What are engineering challenges to develop solar energy for comfort/home uses?
admin answers:
Solar is an old technology now and is fairly developed. Cost is a bit of a barrier but that is coming down quickly. Production scale could also be considered a barrier, as the industry can’t yet make enough solar panels to satisfy demand. The panels themselves are limited in how much energy they can take out of the sun’s rays, but they are getting better at this. Materials are a big thing now, mostly in trying out different materials and structures in the cells to bring down the cost and boost the efficiency.
I came accross a new, proven and tested home made wind power system and solar power system which eliminates our electricity bills. It was written by a Renewable energy enthusiasts Michael Harvey the diy called Earth4energy. You can get your copy to save energy and help environment while eliminating your power bills.

What are the democratic and republican views on solar energy?
What are the democratic and republican views on solar energy?
what are the views, and how do they affect america?

In reality – Solar Farms are not practical or cost effective – YET!
They need to be subsidized by government. Solar panels only have a 10-20 year life.
When solar panels go below the 8 cent per watt cost – then they will be more cost effective.
Some Democrats don’t want their development or wind Farms.
Http://www.nytimes.com/2009/12/22/business/energy-environment/22solar.html
“AMBOY, Calif. — Senator Dianne Feinstein introduced legislation in Congress on Monday to protect a million acres of the Mojave Desert in California by scuttling some 13 big solar plants and wind farms planned for the region.” – – Plus the Kennedy’s stopped a wind farm in Massachusetts.

Your Questions About Solar Generators Costco
Laura asks…
I need help with building an electric car?
I’m soon to be for fourteen and I have been ideas for the future, I plan on building an electric car. I need to find somebody that has already built one and ask you about it.
admin answers:
The one EV car I currently have (have 2 vehicles that run on hydrogen also) I converted from a vw bug and is free to charge. As I live completely off the grid all my electricity comes from solar panels and 2 wind generators, which I also built.
However I did charge up at Costco in Carlsbad California (I actually only drove up there to fill up) if I remember right it was around $2.00
Not sure if you’re interesting in doing it yourself, but I’d be willing to walk you step by step threw the conversion. I’ve converted 3 of my own cars (a datsun truck, ford ban, and a vw bug) and a few for neighbors. I’ve also converted cars to run on hydrogen, ethanol and biodiesel, by far EV is the easiest.
If you’re interested here’s what it would entitle…
– The engine compartment is first cleaned out of any gasoline components.
– Electric components are then installed in exchange.
– A battery bank is built and incorporated.
– Existing starter and driving systems are connected.
– Turn the key, step on the gas pedal sending more energy to the electric motor, & thus more power to the drive system, which in return creates more speed, more acceleration.
– The system has normal automotive top speeds and acceleration, typical to the vehicle your modifying. If your top speed was 85 mph and your acceleration was 1 mile per min, then this will be what your left with after the conversion.
The methods are extremely simple, making the process possible for anyone, everyone, ANYWHERE.
Typical tools, hardware & supplies are used, making access to parts available for all.
Electric Conversions can be easily accomplished in ANY model vehicle, even tractors, Generators, types of machinery, etc.
Project lengths range from 1 day to 1 month.
If you’re interested I wrote a guide on it which is available at www agua-luna com
My last EV conversion ran me about $1400. Everything is available online. I have a how to do it yourself guide available at www agua-luna com that will walk you step by step through the process. If you have ANY questions feel free to contact me through the site. Here’s a list of what you’d need…
Advanced DC Motor
The motor is an 8″ Advanced DC series-wound motor. It weighs 107 pounds and is rated at 68 peak horsepower. These motors are available in several sizes.
Adaptor plate
The adaptor plate mates the motor to the transmission. It is constructed of 1/2 inch aluminum and is pre-drilled with bolt hole patterns for both the motor and transmission. An aluminum spacer is also used for proper spacing between the shafts of the transmission and motor. Adaptor plates are available for many cars.
DC Motor Controller
The controller regulates current going to the motor. It is a solid-state device that uses a pulse width modulator (PWM) that sends short bursts of current to the motor at a rate of 15 kHz. Controllers are available from both Curtis and DCP.
Potbox (Potentiometer)
The potbox is a 5K ohm throttle between the controller and the accelerator, similar to the way a sewing machine pedal works. The potbox’s lever arm is attached to the existing accelerator cable.
Main Contactor
An electric relay that serves the same purpose as the ignition switch in a gas car. When the key is turned to the start position, the contactor closes the circuit to allow current to flow to the controller.
Circuit Breaker
A safety device that shuts down power for servicing or during an emergency. The circuit breaker is installed under the hood and can be switched both off and on from the drivers seat with an extension or cable.
Main Fuse
The main fuse protect the system from high voltage spikes. A fuse should be installed at each battery box or group of batteries.
Shunt
A shunt is placed in series within the wiring as a means to connect meters. Shunts are available in different sizes for both high and low power configurations.
Charger interlock
A relay that keeps the circuit open so nobody will inadvertantly drive off with the charge cord plugged into the car.
DC/DC Converter
The DC/DC converter is similar in function to a gas car’s alternator. It charges the 12 volt accessory battery by chopping voltage from the main battery pack down to 13.5 volts.

Your Questions About Solar Energy Generator Cost
Ruth asks…
How hard is it to install solar panels on a swimming pool?
I was thinking about adding a solar heater to my swimming pool. The panels seem very affordable, but is this something I could install myself with no experience or do i need a professional?
admin answers:
Not hard. This web site provides you a step by step process to build a devise that generates solar and wind energy. Not only will it provide electric for your pool, but can lower your utility bill. The cost to build this generator is under $200.
Carol asks…
What are the best Deep Cycle batteries to use when storing energy from a wind generator and a solar panel?
I hear the forklift batteries are the best but they are to heavy to transport so I was thinking something a bit smaller but still capable of storing a lot of energy.
Well thank you very much !
admin answers:
Deep cycle batteries are the correct choice for renewable energy systems. Unlike your car battery, deep cycle batteries are made to be deeply discharged and recharged many times over the life. When selecting batteries for solar and wind systems, flooded lead acid (FLA) batteries are the most cost effective. They also require maintenance -i.e. Regularly checking the fluid level to ensure longest life. FLA batteries offer the largest storage potential, and batteries can be up to several hundred pounds each.
Besides FLA batteries there are also sealed gel cell and absorbed glass mat (AGM) batteries for RE applications. These batteries are more expensive than FLA batteries and are generally smaller in storage capacity. They are good for remote applications where maintenance would be difficult, and because fluid levels do not need to be maintained, they have a shorter lifespan than the FLA batteries.
Remember to be conservative when calculating battery size for a stand-alone solar or wind system. If your battery bank is undersized, you will not be able to supply the energy you had planned. Battery bank is size is directly dependent on the amount of Watt-hours you are supplying; how many days of autonomy you will need; the depth of discharge; and inverter efficiency. Be sure to look at the battery warranty as well. Rolls-Surrette batteries are known for their quality and are also a bit more expensive upfront. But high quality batteries, if properly cared for, will outlast cheaper batteries and save money in the long run.
Good luck!

Your Questions About Solar Energy Materials And Solar Cells
Maria asks…
How much fossil fuel does it take to make solar cells (energy ratio)?
Count the energy the solar cell can harvest over its lifetime. For the fossil-fuel side, you can use the chemical energy in the material, or the amount that could be obtained with heat engines, but in either event specify which measure you used.

Paul asks…
How do solar cells work?
Hi, can anyone please tell me how solar cells work? Not in too much detail with alot of compicated terminology. I just need to know how they convert solar energy into electrical energy without all the complicated stuff.
Thanks alot!
admin answers:
Detailed Version: A solar cell is composed of a semiconductor with n-type and p-type material, that has a built-in potential at the junction. When light photons hit the semiconductor, they are absorbed and convert the photons energy into an electron and hole pair. These carriers are split by the built-in electric field of the junction in the semiconductor which outputs a current and voltage that can be used for energy.
Less complicated version: light hits a solar cell and the light is converted into a voltage and current similar to a battery which can be used to supply electrical power.

What would you do if society colapsed end every one was on their own?
no cooperation between anyone, not even families
no utilities or power, unless you can provide it for yourself like your own well or generator and if you can you have to protect it from any one else who might want to steal it for them selves.
no sale or trade between people you just have what you own and what you can take or steal from others.
how long do you think you could last? Where would you go? What’s your plan?

Your Questions About Solar Energy Generator Companies
Linda asks…
solar energy used in a real life for what ? and is it successful?
1.successful example of solar power in use of the real life .where in the world it’s successful and why can all sources be used in any country?
2.why not success economically?what improvement have been made ?
admin answers:
You are asking a big question so I advise you to do some research. I will offer some of what I’ve learned.
Solar is getting cheaper at a rapid rate. The solar industry was one of the hotter sectors in the stock market in the last year. Prices are expected to reach grid parity over the next ten years, depending on where you live.
Grid parity means solar is competitive in price without subsidies. Till then we have subsidies.
Some photovoltaic panel makers are saying they may be at grid parity in two to five years.
In sunny areas like California, which also have high electricity prices, prices are already competitive.
In California, the three power companies have already signed on for solar power plants totaling 3 gigawatts. One gigawatt would power San Francisco, for comparison.
These are both photovoltaic and solar thermal power plants.
They are hundreds of megawatts each, and plants as big as 900 megawatts have been proposed. That’s 9/10 of a gigawatt.
Solar thermal power plants use the heat from the sun to generate electricity, usually by boiling water to drive a steam turbine generator. The heat from these plants can be stored and electricity generated at night. Solar thermal plants also won’t fade when a cloud goes over them.
They are fairly competitive now, with claims of 8-12 cents per kilowatt hour.
There is also concentrating solar photovoltaic power plants.
Both these and solar thermal plants, use parabolic mirrors, mirrors that track the sun, or fresnel lenses to concentrate sunlight up to 1000 fold onto a receiver, either thermal, or photovoltaic.
Using less than 1% of our southwest desert lands, solar power plants could power the whole country. This is an area 92 miles by 92 miles, an area which is less than the land now used for coal mining. The January 08 issue of Scientific American featured an article called “A Solar Grand Plan”, a proposal, which you can read online, to do just that.
It proposes building solar thermal and concentrating photovoltaic power plants and a network of high voltage DC transmission lines to distribute the power to other parts of the country. This HVDC distribution system is the same thing that T Boone Pickens is recommending to move wind generated power from Texas to the rest of the country. This will have the added benefit of beefing up the grid, something that is needed anyway.
There is no shortage of good ideas out there. At setamericafree.org, you will find another plan called “A Blueprint for U.S. Energy Security”. This plan shows how we can achieve energy security and meet the goals of reducing the threat of global warming, using current technology. It calls for plug in hybrid cars, which would achieve an overall 100 mpg for the average driver. Once the grid is clean energy, it can power much of our transportation as well.
At that point, electric cars will make perfect sense and will have had more time to perfect the technology.
If you study these two plans and that of T Boone Pickens, you will see they have much in common. By combining the best ideas of these and other similar plans, we can get the job done. For instance, Pickens wants to use natural gas as a cleaner alternative to gasoline in cars. How about plug in hybrid natural gas powered cars? Plug in Partners website has good information on plug in hybrids.
Pickins’ argument for natural gas for cars is a good one, it’s cheap, it’s abundant, it’s cleaner than gasoline, and it’s ours.
And he’s right about something else, we can’t drill our way out of it, and oil is killing our economy.
Those in power want you to believe that these solutions will be too expensive. Nothing could be further from the truth. For example, the solar proposal published by SciAm calls for spending about $400 billion in public money, over a period of about 40 years. This is less public money, than we spent to build the high speed information highway over the last 35 years. And that is about how much we give to oil companies, in the form of tax credits and subsidies, every five years. So by spending about 1/8 of what we now give away to oil companies, we could power the entire nation with solar energy in the southwest.
Add to this solar panels on rooftops, large scale arrays on the ground and such all over the country, and you have both distributed energy and centralized energy, all from solar.
Wind has huge potential too and is cheap.
Both wind and solar large projects are quicker to get up and running than nuclear or coal plants. Cheaper too!
Http://greenwombat.blogs.fortune.cnn.com/
Green Wombat has lots of articles on related issues, with several stories about solar power plants in the southwest.
One thing that is helping is power purchase agreements and other financing designed so that a homeowner, for instance, could install solar panels with no money down. This is also being done in larger commercial installations and utility scale installations.
Berkeley California just voted to finance solar for homeowners. They will sell bonds to finance solar panels for any homeowner that wants them, with no money down. Each year, along with your property tax, you will pay down part of the loan. If you sell your house you can pass on the solar and the debt. It’s a win win.
It no longer will take 20 years to pay off a solar system as someone else said.
There is much dis information out there. Big powers are trying to convince us that renewable energy can’t power the country. It is not true.
All we lack is the political will.
Nancy asks…
how do ordinary people buy and install green technology such as solar and wind in Michigan?
I know these things are MADE in Michigan and TV shows people doing this, but when I search all I get are companies looking to do business with other companies or sites that have no buying info just product info. I don’t understand why there is this disconnect with TV and the Internet. TV pushes the new technology while the internet seems to just now be admitting it exists.
admin answers:
Let me start off by saying we (my family and I) live completely, 100% “off of the grid and are completely self sufficient”
The house is built utilizing natures natural elements, in the shape of an octagon with 8ft wide arch doors on every wall to catch every angle of wind (typical 4 sided homes have half the chance as one with 8 sides. A circle being the most efficient design). Woodburning stoves, solar chimney, solar AC, solar heating, solar water heating (pool and home), solar stove, solar power, wind power, hydrogen powered back up generator, hydrogen back up water heater, hydrogen stove, 2 hydrogen powered trucks, 1 EV (electric vehicle) and satellite internet.
There are no utility lines, no water lines, no roads, tv, cell service, etc. On our ranch. EVERYTHING needed is produced here. All electricity comes from 27 solar panels, 2 main wind gens and a back hydrogen generator if needed (typically we can last 9 days with all luxuries of sunless windless weather, hasn’t happened yet). Water is caught and storaged from the rain. Hot water is made with solar batch water heaters with an on-demand hydrogen hot water heater as backup. Even our vehicles use alternative energy (2 hydrogen trucks, 1 EV electric vehicle converted). Because of this we have no bills, no debt and no mortgage.
The fallowing steps were taking directly out of a DIY guide I offer to those who would like to run their homes on solar power safely, reducing their monthly utility bills or even selling power back the the electrical companies. The entire guide is available at www agua-luna com. Its pretty simple but if you have any problems feel free to contact me directly I can walk you threw the process.
Materials you will need
A sheet of copper flashing from the hardware store. This normally costs about $5.00 per square foot. We will need about half a square foot.
Two alligator clip leads.
A sensitive micro-ammeter that can read currents between 10 and 50 microamperes. Radio Shack sells small LCD multimeters that will do, but I used a small surplus meter with a needle.
An electric stove. My kitchen stove is gas, so I bought a small one-burner electric hotplate for about $25. The little 700 watt burners probably won’t work — mine is 1100 watts, so the burner gets red hot.
A large clear plastic bottle off of which you can cut the top. I used a 2 liter spring water bottle. A large mouth glass jar will also work.
Table salt. We will want a couple tablespoons of salt.
Tap water.
Sand paper or a wire brush on an electric drill.
Sheet metal shears for cutting the copper sheet.
The first step is to cut a piece of the copper sheeting that is about the size of the burner on the stove. Wash your hands so they don’t have any grease or oil on them. Then wash the copper sheet with soap or cleanser to get any oil or grease off of it. Use the sandpaper or wire brush to thoroughly clean the copper sheeting, so that any sulphide or other light corrosion is removed.
Next, place the cleaned and dried copper sheet on the burner and turn the burner to its highest setting.
As the copper starts to heat up, you will see beautiful oxidation patterns begin to form. Oranges, purples, and reds will cover the copper.
As the copper gets hotter, the colors are replaced with a black coating of cupric oxide. This is not the oxide we want, but it will flake off later, showing the reds, oranges, pinks, and purples of the cuprous oxide layer underneath.
The last bits of color disappear as the burner starts to glow red.
When the burner is glowing red-hot, the sheet of copper will be coated with a black cupric oxide coat. Let it cook for a half an hour, so the black coating will be thick. This is important, since a thick coating will flake off nicely, while a thin coat will stay stuck to the copper.
After the half hour of cooking, turn off the burner. Leave the hot copper on the burner to cool slowly. If you cool it too quickly, the black oxide will stay stuck to the copper.
As the copper cools, it shrinks. The black cupric oxide also shrinks. But they shrink at different rates, which makes the black cupric oxide flake off.
The little black flakes pop off the copper with enough force to make them fly a few inches. This means a little more cleaning effort around the stove, but it is fun to watch.
When the copper has cooled to room temperature (this takes about 20 minutes), most of the black oxide will be gone. A light scrubbing with your hands under running water will remove most of the small bits. Resist the temptation to remove all of the black spots by hard scrubbing or by flexing the soft copper. This might damage the delicate red cuprous oxide layer we need to make to solar cell work.
Cut another sheet of copper about the same size as the first one. Bend both pieces gently, so they will fit into the plastic bottle or jar without touching one another. The cuprous oxide coating that was facing up on the burner is usually the best side to face outwards in the jar, because it has the smoothest, cleanest surface.
Attach the two alligator clip leads, one to the new copper plate, and one to the cuprous oxide coated plate. Connect the lead from the clean copper plate to the positive terminal of the meter. Connect the lead from the cuprous oxide plate to the negative terminal of the meter.
Now mix a couple tablespoons of salt into some hot tap water. Stir the saltwater until all the salt is dissolved. Then carefully pour the saltwater into the jar, being careful not to get the clip leads wet. The saltwater should not completely cover the plates — you should leave about an inch of plate above the water, so you can move the solar cell around without getting the clip leads wet.
Now place in the sun with the magnefied on top.
The solar cell is a battery, even in the dark, and will usually show a few microamps of current.
That’s it it’s that simple. If you’d a more detailed process and some pics (ouldn’t put them here) it’s available along with some other DIY alternative energy projects at www agua-luna com
Hope this helped, feel free to contact me personally if you have any questions if you’d like assistance in making your first self sufficient steps, I’m willing to walk you step by step threw the process. I’ve written several how-to DIY guides available at www agua-luna com on the subject. I also offer online and on-site workshops, seminars and internships to help others help the environment.

Your Questions About Solar Energy Facts
Chris asks…
What are some inherencies on solar energy?
Hello, I am in a debate class and I need some inherencies on solar energy please, thanks
admin answers:
Sure:
Inherency-Current administration opposes R+D now
“Top energy official extols Colorado based federal lab” Nov 8 2007
Judith Kohler.
Fact: NREL has laid off 32 employees and suffered a $28 million shortfall (National Renewable Energy Lab) So currently understaffed and underfunded national labs for renewable energy research.
Inherency-tax credits for renewable energy have fallen prey to cost cutting related to the Iraq war
“Foster: Dems pushing for renewable energy,” March 29, 2008 UPI
There is an effort underway to extend and renew tax cuts supporting the production and use of renewable energy. The tax cuts for renewable energy have little chance of passing due to the costs of the Iraq war. (how ironic is that, LOL)
These two inherencies prove that the US is not currently doing enough to support research and development of renewable energy such as solar, and also not extending tax credits to promote development and purchase of renewable energy such as solar.
Also, look out your window. How many solar panels do you see? There is an inherency right there.
Ken asks…
I have a 300+ acre land and I want to build a green energy farm. What do I have to do and consider?
I am thinking of utilizing geothermal, wind, and solar energy generation. Can I do that on my land?
admin answers:
You need to find out what potential your property has. Any of the three will work but the question is what will be the better of the three and at what cost. Geothermal, while one of the best forms of electricity, is also the most expensive to place in areas where Geothermal heat is located to deep underground to be practical to be harnessed.
Wind energy can be very efficient and cheap to harness but in areas where the wind doesn’t blow consistently wind generation can be a frivolous pursuit.
Solar energy while not as efficient is very cheap and can be set up in pretty much any location that gets a good supply of light. The down side to solar energy is the fact that current capture capabilities of solar are only about 10% at the very best (8% is industry standard to date) The lack of efficiency in the collection cells makes it necessary to build Immense collectors to make up for the deficiency in energy capture.
You might begin by conducting a few simple tests to see what energy would best be created on your location. Other than that I would consider only making what you need to sustain your own life on 300 acres because what you will get out of a commercial endevour is minimal.

It won’t always save money. In general, solar saves money where
1) Electricity is expensive
2) There is a lot of sun year-round
3) There is already grid electricity
These conditions are satisfied in most of California and Hawaii. In other places, google for local solar installers, and ask them for local references. If there are no local references, chances are your area is not good for solar, at least not today.

thanks in advance to all your answers
admin answers:
The Thermosiphon hot water system is the best. No moving parts and no electricity needed. The size is dependent of the number of people using it. The down side is the weight of the system. If you have the space on the ground, it would be ideal. If not you may need to make your roof stronger.
Solar systems work better in tropical zones. If you live in outside this area you need more panels. Best if you talk with several solar companies and compare prices.
Photovoltaic systems to convert sun to electrical is very expensive at this time, but some parking lots in my state (Hawaii) have installed solar lights with wind generators to keep the system going 24/7. That system has been running for over four years and is a wonderful addition to any area where you want security lights during the nights. The downside is the noise from the wind generators. It will keep you up all night if you are a light sleeper. I purchased a couple of solar spotlights and it’s ok but only gives about six hours after the sun goes down.
Solar cookers designs are all over the Internet. Best if you build and design one yourself.. The down side is most people are working during the day to get full advantage of this system.
Hope you get your 100 dollars.

Why is solar energy generators are so costly (India)?
When the whole world is speaking about global warming, extinction resources like charcoal for electricity why is the Solar energy generating equipments are so costly ? It roughly takes 15000 INR for 1 fan, 1 tube light, 5 9W CFL bulbs for 1 hour back up.
admin answers:
Solar energy itself may be considered clean and easy to harness, but the materials needed to transduce sunlight into electricity are very expensive.
Http://en.wikipedia.org/wiki/Solar_cell
http://en.wikipedia.org/wiki/Refined_silicon#Purification
Silicon wafers, needed to produce solar cells, are difficult to manufacture. The silicon must be of high purity, which is achieved by a lengthy and expensive process.
There are other possible ways being researched, such as polymer solar cells that don’t require silicon.

Jenny asks…
Careers in Solar energy and Photovoltaics?
I am really interested in solar energy(currently in high school).I wanted to take up a career in this field.I would like to know the available choice of careers in the area and the academic requirements for the same.
admin answers:
You can do research on making and fitting solar cells. This would require engineering, chemistry or physics… At school you’d have to stay on top of maths & sciences.
You could work for a company that fits solar cells, in which case you could get on an apprenticeship or similar. A bit of maths and practical subjects like electronics (if you can) wouldn’t go amiss.
Alternatively, you could try getting work for a power company that deals with solar power. They will need people with skills in marketing and business. For other things they would need people with problem solving skills, the sort of things you pick up from maths, physics etc. I’m not sure how competitive these are…
I did a physics degree and I’m now writing up my Masters thesis in solar cell research. The other people in my research group either had degrees in physics, although one guy did electronics engineering.
I could have got a job with a power company, solar cell company or a PhD in solar cell research from here. Whatever path to solar you take, it’s safest to make sure you stay on top of maths and science at school IMO.
Chris asks…
I’m interested in a career in Solar Energy. What kind of College Major is required?
I’m going to be a senior in high school this year and I need to find a major to accomodate my goals. I believe a degree in engineering is the way to go. I hope go to to the University of Texas at Austin because they have courses in Solar, but it is not indicated what major it is associated with. Even if I do carreer in solar energy, what can I expect to be doing as part of my job?
admin answers:
If you want to stay on the “practical side” of solar energy, take a degree in Mechanical Engineering or Mechanical Engineering Technology for your undergraduate degree.
If you want to go to the Research side, take Engineering Physics or Engineering Mechanics, or perhaps Electrical Engineering, then follow up with a Master’s degree.
One interesting non-Engineering degree is offered by James Madison University:

Whats YOUR plan for the Zombie Apocalypse?
Zombie Apocalypse is “code” for any general widespread disaster (the plan remains the same)
So. Here’s the deal. No power/plumbing, Harsh sun radiation, infected Zombies. Going out in the sun will be like being in a microwave oven, but night is OK. Others are also trying to survive the apocalypse in your neighborhood, so there will be Bandits/Gangs taking a violent path to survive the Apocalypse.
So whats your Plan to survive? What? no PLAN?!? I guess you’re Zombie meat then. Here’s MY plan
I have this Wal-Mart nearby. Up on a ridge near a highway hill cutout- 2 bridges that cross the cutout “canyon” to get to it. It is a Wal-Mart, Home Depot, Grocery Store complex… and will be my Fortress. I will board up the WalMart, and arm up in the hunting supply section of the store. Walmart has those cinder block-proof windows, so is actually pretty defensible. Theres an auto shop in the back of the WalMart where I will up-armor my Truck.
In the nights I will go over to the Home Depot, and get all the Portable Generators, Propane tanks, Sheet Rock, Diamond Plate, Piping, Tubing, and Fencing to further Fortify WalMart, as well as tools and solar panels and other much needed items.
I am an Electrician by trade, so MY Fortress will be one of the few outposts with Power and Lights still. I know how to power a microwave with a 10 speed, a car alternator, a car battery, and an inverter. There will be lots of cars out in the walmart parkinglot, alternators, batteries, and gas tanks as well.
One of my first long distance missions will be to get to a gun store/pawn shop, to get serious weapons, not so much for Zombies, but for bandit raiders who may try to TAKE what Ive got.
and so on, and so on. Thats my rough Zombie Apocalypse Plan. So.. whats YOURS?!?

What is it that you need to know.
Enjoy island living-hang out at the beach before sundown, and early on the weekends.
Don’t be afraid to explore and get to know the island folks. Everyone is always welcome to a church fiesta (To honor the church’s saints) Catholic or not. Check out the Chamorro village Wednesday nights and mix with the locals and check out the food and handicrafts. Go to the island fairs.
Its hot 95% of the time but it cools off a bit at night (Sure you know that).
Power costs are high. Use energy saver lightbulbs and appliances.
Always have an umbrella handy in your car for occasional rain.
Be prepared for occasional power outages and typhoons (Its been awhile though). You know, battery operated flashlights, radio, matches/lighters, candles, gas stove, and even a generator come in handy for extended power outages after a typhoon. Also, canned foods, etc..
Bring stuff from the states that you can’t find here at either Home Depot, Macy’s, Ross, Payless Shoes, or Kmart. Creature comforts. We brought solar camping lanterns with us from Wal-Mart stateside.

Your Questions About Solar Energy Generators
Mary asks…
New horizons spacecraft now in a way to fly by Pluto around 2015 is fueled by solar energy alone or what else?
Is it possible to send the spaceship entirely working over solar energy?
admin answers:
New Horizons is powered by a Radioisotope Thermoelectric Generator. Most spacecraft are indeed powered by solar panels linked to a bank of batteries, but that would not be feasible for New Horizons. The sunlight in the outer Solar System is too feeble for solar cells to be effective. Although they are powered by the decay of Plutonium-238, they are not nuclear reactors. They are pellets of plutonium dioxide encapsulated in a heavily armored container to prevent the plutonium from escaping in the event of a launch vehicle failure that results in a crash or explosion. Plutonium 238 has a half-life of 87 years and because it emits mostly alpha particles, it it not very dangerous unless it was inhaled or ingested from a radiological point of view. Indeed, only lightweight radiation shielding is required for an RTG. Plutonium is however also a very poisonous heavy metal, which is why NASA builds as strong a container for the RTG’s as possible to reduce the risk of Plutonium escaping. That is one reason it is put in RTG’s in the form of an oxide and that is vitrified to further contain the Plutonium. Inside them are devices called thermocouples. As the Plutonium-238 decays alpha particles and heat are released. The heat is converted by the thermocouples to generate electrical power, which operates all of New Horizon’s systems. The advantage of this system over a nuclear reactor is there’s no way for it to melt down or go “runaway.” They cannot explode, nor can they cause a massive radiation release because the amount of fuel they carry is very small. Plutonium-238 cannot be used to build nuclear weapons either. They are compact, radiation proof and will generate power for decades no matter how the spacecraft is oriented with respect to the Sun. As they Voyagers have shown, they will operate even in interstellar space. They gradually produce less and less electricity over time, and eventually New Horizons will not have enough power to run it’s instruments and it’s other systems. At that point it’s mission will end and New Horizons will become mankind’s fifth piece of interstellar space junk as well as time capsule.
Steven asks…
Would it be possible to derive electrical energy from roads heating up during the day?
Just an idea that occurred to me during a conversation today. Solar energy is becoming pretty trendy these days, and it seems to be that with how hot roads get, they are basically solar panels. Admittedly thermal rather than electric, but would it somehow be possible to turn this heat into electricity? It seems to be a rather vast untapped resource if so.
admin answers:
Its complex, and expensive, but a great idea. I’ve thought it before.
The only way to do it is to use a thermal cycle with a refrigerant. You need to embed a heat exchanger (tubes) in the road. They need to be able to withstand temperatures, thermal flexing, salt, mechanical loading from cars. There are some issues to overcome.
If you use the right medium it undergoes a phase-change at the operating temperature of a road, that sucks up a TON of energy. You pump in a liquid, pump out a gas. With hot gas you can either run it through some sort of generator, or use it to heat something else up then run the something else through a generator.
So you might think of putting fins on the coils and making them more like long lines. Here in Phoenix AZ the hot summer sun only radiates 1kw/sq-meter. You can compute from the radiation coefficient and the temperature of the pavement what part of that is re-radiated away. Its likely significant. Bottom line: to get meaningful power you must have large area of pavement soaking up light.
There is a good book in thermal system design by Boehme from the 1980’s. You could find it, check it out using inter-library loan, and then put the idea as something in a science fair. If someone likes it, they could support your work, if not you can still earn glory and scholarships. A good heat transfer text would also do you pretty well.

I am making a model of a miniature eco friendly city, Please help!?
We’ll be making many small houses, showing different means of non-conventional power resources and their uses. One of the house will have a small LED light, which will be using a small solar cell, which I’ll take out from a Simple calculator. The other house will have a hydro-generator, that is, a small motor, used in electric car toys, which will too generate electricity.
Can anyone give me any more ideas, and review my current ideas?
Will they actually work?
admin answers:
If you could find a piece of tile, or a clay pot, and it it on the “south wall” of the house. Ad take an incandescent light to simulate the sun (incandescent for the heat) this will act as a heat storage wall. (one way to save on heating bills is to have clay/tile floors or walls, with the southern sun directly on it. Some walls even can have water capsuls in them. And this takes the sun’s heat and retains it for the night.

The one EV car I currently have (have 2 vehicles that run on hydrogen also) I converted from a vw bug and is free to charge. As I live completely off the grid all my electricity comes from solar panels and 2 wind generators, which I also built.
However I did charge up at Costco in Carlsbad California (I actually only drove up there to fill up) if I remember right it was around $2.00
Not sure if you’re interesting in doing it yourself, but I’d be willing to walk you step by step threw the conversion. I’ve converted 3 of my own cars (a datsun truck, ford ban, and a vw bug) and a few for neighbors. I’ve also converted cars to run on hydrogen, ethanol and biodiesel, by far EV is the easiest.
If you’re interested here’s what it would entitle…
– The engine compartment is first cleaned out of any gasoline components.
– Electric components are then installed in exchange.
– A battery bank is built and incorporated.
– Existing starter and driving systems are connected.
– Turn the key, step on the gas pedal sending more energy to the electric motor, & thus more power to the drive system, which in return creates more speed, more acceleration.
– The system has normal automotive top speeds and acceleration, typical to the vehicle your modifying. If your top speed was 85 mph and your acceleration was 1 mile per min, then this will be what your left with after the conversion.
The methods are extremely simple, making the process possible for anyone, everyone, ANYWHERE.
Typical tools, hardware & supplies are used, making access to parts available for all.
Electric Conversions can be easily accomplished in ANY model vehicle, even tractors, Generators, types of machinery, etc.
Project lengths range from 1 day to 1 month.
If you’re interested I wrote a guide on it which is available at www agua-luna com
My last EV conversion ran me about $1400. Everything is available online. I have a how to do it yourself guide available at www agua-luna com that will walk you step by step through the process. If you have ANY questions feel free to contact me through the site. Here’s a list of what you’d need…
Advanced DC Motor
The motor is an 8″ Advanced DC series-wound motor. It weighs 107 pounds and is rated at 68 peak horsepower. These motors are available in several sizes.
Adaptor plate
The adaptor plate mates the motor to the transmission. It is constructed of 1/2 inch aluminum and is pre-drilled with bolt hole patterns for both the motor and transmission. An aluminum spacer is also used for proper spacing between the shafts of the transmission and motor. Adaptor plates are available for many cars.
DC Motor Controller
The controller regulates current going to the motor. It is a solid-state device that uses a pulse width modulator (PWM) that sends short bursts of current to the motor at a rate of 15 kHz. Controllers are available from both Curtis and DCP.
Potbox (Potentiometer)
The potbox is a 5K ohm throttle between the controller and the accelerator, similar to the way a sewing machine pedal works. The potbox’s lever arm is attached to the existing accelerator cable.
Main Contactor
An electric relay that serves the same purpose as the ignition switch in a gas car. When the key is turned to the start position, the contactor closes the circuit to allow current to flow to the controller.
Circuit Breaker
A safety device that shuts down power for servicing or during an emergency. The circuit breaker is installed under the hood and can be switched both off and on from the drivers seat with an extension or cable.
Main Fuse
The main fuse protect the system from high voltage spikes. A fuse should be installed at each battery box or group of batteries.
Shunt
A shunt is placed in series within the wiring as a means to connect meters. Shunts are available in different sizes for both high and low power configurations.
Charger interlock
A relay that keeps the circuit open so nobody will inadvertantly drive off with the charge cord plugged into the car.
DC/DC Converter
The DC/DC converter is similar in function to a gas car’s alternator. It charges the 12 volt accessory battery by chopping voltage from the main battery pack down to 13.5 volts.

Jenny asks…
I wan to install solar panels in all my windows. Any help and can I get enough energy?
I am living in a high rise apartment. I have heard of solar panels use for all sorts of things but I have not heard of solar panels being install in any window. Windows are normally inserted vertically. If it can be done, I would save a lot of money on my electrical bills on all electrical ancillary items. It is so scary to have electrical bills going up everyday with the increase onwards of fuel prices.
admin answers:
Solar power windows can save you a lot of money on your energy bill. This type of window actually doubles as a solar panel for the home. The are generally designed to keep cold air out of the home. If you’re looking to improve your home and to make it a green home, then purchasing solar panel windows and installing them is a project you will want to do. Follow this guide to install your new solar power windows.
Step 1 – Understand What the Window Is
Before you install the new windows, you should understand what they do. Solar power windows are made with solar panels. The solar panels allow the passage of light through the window into the home. In addition, it also produces energy for the home. In 2008, scientists created a much more powerful solar paneled window for home use. Some research shows that these newer panels are 10 times more effective in drawing out energy for the home. If the home has a generator that can connect the solar power to produce energy, it will become much more efficient in energy production and less dependent upon traditional energy resources.
Step 2 – Remove Old Windows
Remove the old windows from the home. Tape up the hole that you just created, especially if you don’t plan on installing the new windows just yet. You can usually pull out the old window by removing the window framing and the window sill. The window should just pop out.
Step 3 – Add the New Solar Window
Installing solar powered windows is similar to installing a regular window. It comes with a frame and a sash, a sill and any necessary hardware. Install the window from the outside of the home to the inside. It will usually pop into place. Be careful not to scratch the surface of the window, as the solar properties will reduce if the window is damaged. Add the sash, the sill and the frame. Nail into place.
Step 4 – Connect to the Generator
Follow the directions on your solar powered window. There will be instructions on how to appropriately connect the window to the solar generator. If you don’t have a solar generator, you can skip this step. Understand that in order to harness the solar effects the windows create, you will need to have a generator or power pack that can change this energy from solar into usable energy for your home.
Step 5 – Clean the Window
Using a non-abrasive solution, clean your window. Usually water and newspaper works the best. Don’t use razors or any other types of sharp objects on your window, because you will ruin the solar properties.
Good luck!
Sandra asks…
Why should people use solar panels more for houses?
I need to write a pressuasive essay on why we should use solar panels more than we do. and convince people that their good and stuff.. if u guys could give me some good key reasons why..that would be great.
admin answers:
Hey Dave. There are lots of good reasons why we should use more solar panels. To set one thing straight, panels do not have toxins in their manufacture. Photovoltiac panels, the ones that produce electricity are made up almost entirely of silicone, aluminum and acrylic. The other type, that heat water and air from the sun are made primarily of sheet metal, copper and glass, and have a type of alcohol called glycol running through them. It’s the same type that we use to deice aircraft in the winter.
Whsgreen is quite right on the payback. If you invest properly in solar power today and take advantage of any grants and tax incentives, even if your electric rates do not go up as they are forecast too, you will get your money back over time, well within the lifetime of the equipment, and sooner if there is a rate increase in the future. There are also enviromental benefits. At one time there was an argument that a solar panel will never produce as much power as was used to manufacture it. First of all, this is not correct. The, “Embodied Energy,” in a solar panel is earned back in 2 – 6 years, depending on the type panel, where the raw materials were shipped from, and how it was installed and used in the end. Most panels are warrantied to last at least 25 years, and most last much longer than that. But the argument is not important anyway. We have been living with electricity for over a century now, so it isn’t going away anytime soon. The question is, “What is the best way to produce it?” If you build a panel, and put it along side a similar sized natural gas fired turbine generator for example, which earns back its embodied energy sooner? The answer is the gas turbine never does, because once you build it, ship it and install it, you now have to feed it natural gas for the rest of its life, so it keeps on digging itself a deeper and deeper embodied energy hole that it can never crawl out of. At least the panel has a chance to get even environmentally. So manufacturing and using solar panels in the end releases less pollution into our environment.
There are also mechanical and political benefits. We all know after the oil embargo of 1973, and the gulf war what it means for our country to rely on foreign oil. Wouldn’t it be nice if we only shipped in 20% of our energy instead of 60% the next time something like that happens? Our home has been powered by the wind and sun for years now, but we still remain connected to the electric grid. Last year alone there were two power failures in our county that lasted about a half day each. In both cases, we were not aware of them because our solar array kept on feeding the house. It’s difficult to put a price tag on something like that.
Beyond the mechanical, political and environmental benefits however, lies a less obvious benefit, the social benefit. Right now we pump oil out of the ground, and mine for coal. The process of getting those materials to market involves shipping, military escorts and other activities that use up a good portion of that energy as well as putting lives at risk. Jobs in solar power are higher tech than jobs in coal mining, oil drilling and shipping, and there are more of them. Using more solar power would require us to put more people to work, and increase our education base because the work involved requires certain skills. I would personally like to take all those people out of the coal mines, send them to school and put them to work building solar panels. Nobody would have to die again in one orf those dark holes in the ground trying to find food for our hungry power plants. They could work on a factory floor where they would not be exposed to coal dust, radon and other toxins and dangers. Most of our solar and wind resources are spread pretty evenly over the middle half of our globe, so everyone has access. This puts people in Bogota on a more equal footing with people in Boca Raton by giving them access to electricity, heat and clean water, and the education to use the solar resources that provide those things. Oil, coal and natural gas is generally piled up in a few places, such as Russia and the Middle East. This gives those countries and the richer governments that rule them more horse power in bargaining for the other resources of our planet. These are the things that wars are made of.
So there are lots of good reason to use more solar in our everyday life. Here are some resources to look up and do some of your own reading. Good luck Dave, and take care. Rudydoo

Your Questions About Solar Energy International
Sandra asks…
Which types of Solar Energy are available in India?What is Solar Panel ?What is the scope of Solar Energy?
Picture of solar Panel.What is Solar Cooker?Advantages of Solar Energy.Disadvantages of Solar Energy.Uses of Solar Energy.
admin answers:
A photovoltaic module or photovoltaic panel is a packaged interconnected assembly of photovoltaic cells, also known as solar cells. The photovoltaic module, known more commonly as the solar panel, is then used as a component in a larger photovoltaic system to offer electricity for commercial and residential applications.
Because a single photovoltaic module can only produce a limited amount of power, many installations contain several modules or panels and this is known as a photovoltaic array. A photovoltaic installation typically includes an array of photovoltaic modules or panels, an inverter, batteries and interconnection wiring.
Solar Energy Advantages :
———————————–
Saves you money :
————————
After the initial investment has been recovered, the energy from the sun is practically FREE.
The recovery/ payback period for this investment can be very short depending on how much electricity your household uses.
Financial incentives are available form the government that will reduce your cost. (visit www.dsireusa.org to find out about incentives available in the state you live in!).
If your system produces more energy than you use, your utility company can buy it from you, building up a credit on your account! This nifty little scheme is called “net-metering”.
It will save you money on your electricity bill if you have one at all.
Solar energy does not require any fuel.
It’s not affected by the supply and demand of fuel and is therefore not subjected to the ever-increasing price of gasoline.
The savings are immediate and for many years to come.
The use of solar energy indirectly reduces health costs.
Environmentally friendly:
——————————–
Solar Energy is clean, renewable (unlike gas, oil and coal) and sustainable, helping to protect our environment.
It does not pollute our air by releasing carbon dioxide, nitrogen oxide, sulphur dioxide or mercury into the atmosphere like many traditional forms of electrical generation does.
Therefore Solar Energy does not contribute to global warming, acid rain or smog.
It actively contributes to the decrease of harmful green house gas emissions.
It’s generated where it is needed.
By not using any fuel, Solar Energy does not contribute to the cost and problems of the recovery and transportation of fuel or the storage of radioactive waste.
Independent/ semi-independent:
——————————————–
Solar Energy can be utilized to offset utility-supplied energy consumption. It does not only reduce your electricity bill, but will also continue to supply your home/ business with electricity in the event of a power outage.
A Solar Energy system can operate entirely independently, not requiring a connection to a power or gas grid at all. Systems can therefore be installed in remote locations (like holiday log cabins), making it more practical and cost-effective than the supply of utility electricity to a new site.
The use of Solar Energy reduces our dependence on foreign and/or centralized sources of energy, influenced by natural disasters or international events and so contributes to a sustainable future.
Solar Energy supports local job and wealth creation, fuelling local economies.
Low/ no maintenance:
—————————–
Solar Energy systems are virtually maintenance free and will last for decades.
Once installed, there are no recurring costs.
They operate silently, have no moving parts, do not release offensive smells and do not require you to add any fuel.
More solar panels can easily be added in the future when your family’s needs grow.
Solar Energy Disadvantages:
—————————————
The initial cost is the main disadvantage of installing a solar energy system, largely because of the high cost of the semi-conducting materials used in building one.
The cost of solar energy is also high compared to non-renewable utility-supplied electricity. As energy shortages are becoming more common, solar energy is becoming more price-competitive.
Solar panels require quite a large area for installation to achieve a good level of efficiency.
The efficiency of the system also relies on the location of the sun, although this problem can be overcome with the installation of certain components.
The production of solar energy is influenced by the presence of clouds or pollution in the air.
Similarly, no solar energy will be produced during nighttime although a battery backup system and/or net metering will solve this problem. See www.dsireusa.org for details on how net metering allows you to save electricity and money.
As far as solar powered cars go – their slower speed might not appeal to everyone caught up in today’s rat race.
Mark asks…
How do I make my own country?
Well.. I have a massive ship out at sea. We have over 100 potential citizens, we’ve been out at sea in the Pacific for 13 years. When we’re near another country in international waters, we send rowboats to do some international business (buying food and whatnot). We are self sufficient in that we process seaweed snacks and fish. We are also energy efficient with solar energy. How do we apply for countryship?
admin answers:
Buy a bunch of dirt–a real big bunch–and find a place in the middle of the ocean where there is no country and put the dirt there. Build houses, make a flag and move in.

Your Questions About Solar Generators Lowes
Helen asks…
how much solar power do i need to run a small frig and heater?
admin answers:
Get the wattage ratings off the name plates, double the wattage rating of the frig and add that to the wattage ratting of the heater and you have you answer. Enough solar cells to power this would cost a LOT more than a generator from Lowe’s.

Your Questions About Solar Energy Generator Wikipedia
James asks…
could the weight of a boat generate energy?
in other words can you harness the energy from the rise and fall of the tide with a cable tied to a very heavy boat then to a pier generate energy? or used to pull a flywheel or something? would the weight of the boat pulling on the cable be able to wind something or spin a flywheel?
what about the simple fact that the boat lowering down would pull the cable with the force of the weight of the boat?
admin answers:
Yes, and New York has installed them on the bottom of the Hudson River.
In this case they are using the in flow and out flow of the tide to generate electricity. The installation was shown on the Discovery Channel and the first one installed was bent because they didn’t plan on the force being so great.
There are wave generators and have been for a while they use up and down motion of the water to move a piston harnessed to a wheel that turns a generator making electrical energy.
Since the waves always move you won’t have to worry about not having enough windy days or not. The problem is that if you are not careful with the design ti will break too easily. This is using wave motion not tidal energy.
If you wanted to create a tide generator then you should go to the Bay of Fundy (http://en.wikipedia.org/wiki/Bay_of_Fundy), which has over 12′ tides each day.
The tides themselves are not that strong, they are only dependent on the gravitational energy of the moon and the sun. The heat of the sun drives the motion of waves and the winds that energy is more consistent and reliable. A more efficient conversion is to take the energy from the original source (the sun) in the first place. Solar panels are a good example of this and recent work in carbon fibers have increased the efficiency of them, once the price of making carbon nanofibers drops (or the price of energy continues to rise) it will become worthy of mass scale production.
There is an idea to use electrical generators on the bottom of the ocean just off the Eastern shore of North America in the middle of the Gulf Stream. The Gulf Stream is a reliable current that constantly runs and the turbines can be made large enough so that they would move slowly so as to not harm fish. It would be just like putting windmills on the floor of the ocean. The only problem of course is making sure to not let the water get in and salt water is very corrosive. A magnetic induction system could solve that problem though.
Steven asks…
what is the political and social effects of geothermal energy?
what is the economical cost ?
what is the opportunity cost?
please help!
admin answers:
Geothermal power requires no fuel (except for pumps), and is therefore immune to fuel cost fluctuations, but capital costs are significant. Drilling accounts for over half the costs, and exploration of deep resources entails significant risks. A typical well doublet (extraction and injection wells) in Nevada can support 4.5 megawatts (MW) and costs about $10 million to drill, with a 20% failure rate.
In total, electrical plant construction and well drilling cost about 2-5 million € per MW of electrical capacity, while the break–even price is 0.04-0.10 € per kW·h. Enhanced geothermal systems tend to be on the high side of these ranges, with capital costs above $4 million per MW and break–even above $0.054 per kW·h in 2007. Direct heating applications can use much shallower wells with lower temperatures, so smaller systems with lower costs and risks are feasible. Residential geothermal heat pumps with a capacity of 10 kilowatt (kW) are routinely installed for around $1–3,000 per kilowatt. District heating systems may benefit from economies of scale if demand is geographically dense, as in cities, but otherwise piping installation dominates capital costs. The capital cost of one such district heating system in Bavaria was estimated at somewhat over 1 million € per MW. Direct systems of any size are much simpler than electric generators and have lower maintenance costs per kW·h, but they must consume electricity to run pumps and compressors. Some governments subsidize geothermal projects.
Geothermal power is highly scalable: from a rural village to an entire city.
A geothermal heat pump can extract enough heat from shallow ground anywhere in the world to provide home heating, but industrial applications need the higher temperatures of deep resources. The thermal efficiency and profitability of electricity generation is particularly sensitive to temperature. The more demanding applications receive the greatest benefit from a high natural heat flux, ideally from using a hot spring. The next best option is to drill a well into a hot aquifer. If no adequate aquifer is available, an artificial one may be built by injecting water to hydraulically fracture the bedrock. This last approach is called hot dry rock geothermal energy in Europe, or enhanced geothermal systems in North America. Much greater potential may be available from this approach than from conventional tapping of natural aquifers.
Estimates of the electricity generating potential of geothermal energy vary six–fold, from .035 to 2 TW depending on the scale of investments. Upper estimates of geothermal resources assume enhanced geothermal wells as deep as 10 kilometres (6 mi), whereas existing geothermal wells are rarely more than 3 kilometres (2 mi) deep. Wells of this depth are now common in the petroleum industry. The deepest research well in the world, the Kola superdeep borehole, is 12 kilometres (7 mi) deep. This record has recently been imitated by commercial oil wells, such as Exxon’s Z-12 well in the Chayvo field, Sakhalin.
System efficiency does not materially affect operational costs as it would for plants that use fuel, but it does affect return on the capital used to build the plant. In order to produce more energy than the pumps consume, electricity generation requires relatively hot fields and specialized heat cycles.[citation needed] Because geothermal power does not rely on variable sources of energy, unlike, for example, wind or solar, its capacity factor can be quite large – up to 96% has been demonstrated. The global average was 73% in 2005.

Daniel asks…
How solar energy can be generated at competitive cost?
How solar energy can be produced at competitive cost for the welfare of people at large?Presently what is the status of its use in india?
admin answers:
Use materials from space (moon or asteroids) to build solar generating plants in Geostationary orbit and beam the power down to a rectena using microwaves.
We lack the space infrastructure needed to do that so it’s decades away but it is probably the only way solar will be cost competitive (and if we didn’t have nuclear power which could provide the zero emissions power we need it’d be our best bet for solving global warming).
There aren’t really any countries that actually have significant amounts of solar generation (and certainly none that get the majority of power from solar, unless you count hydro-electricity or fossil fuels as solar power (but if you do that then you’d also have to call photovoltaics nuclear)).
I came accross a new, proven and tested home made wind power system and solar power system which eliminates our electricity bills. It was written by a Renewable energy enthusiasts Michael Harvey the diy called Earth4energy. You can get your copy to save energy and help environment while eliminating your power bills.

How can we store solar energy in Springs to run a vehicle?
Is there any way we can store solar energy into compression of spring and later release springs when we want to run vehicle. Is there any way we can use compressed springs to run motor.
Any idea on possible system design would be highly appreciated.
admin answers:
Well it sounds like a logical answer, but due to friction and mechanical losses this would not work.
The current ideas are the best store solar energy in batteries for future use yes that does work.
Pressure vessels is another idea the problems are also not a good idea so discount that one.
The idea of a hydrogen cell which gets it’s gas from water is probably the best idea but this does require a small amount of acid to make the water change state with a little electricity.
