Donna asks…
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.
Joseph asks…
Where exactly are Obama’s Green Jobs going to come from?
Why build a solar panel here when China can pay their workers $1/day to build the panel?
China controls 95% of rare earth metals to make the generators.
70% of the Green Energy components are already being imported.
So exactly what are blue collar workers going to build here that China can for much less?
We might need a few service techs to check on things but I don’t see millions of new jobs.
admin answers:
He is creating thousands of jobs in China and India.
Sheesh. Everyone is so demanding!

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:

James asks…
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?!?
admin answers:
My plan is to look for a walmart with the lights on, grab some weed and bribe my way in.
What, you forgot weed?
It’s your lucky day, let me in !

admin answers:
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.

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.

Anyone read this solar panel ebook before?
I have come across an ebook which talking about building own solar panel and wind generator in less than $200. Anyone read this ebook before? Is the method taught inside it working? My friend, who is an engineer is thinking to purchase one and would like to know some review from those who have read it before. Thanks.
This is the website for the solar panel’s ebook: http://ourguide.brinkster.net
Thanks again.
admin answers:
The only people I trust, since they have been into alternative energy since 1969 , is the folks who run a magazine called Mother Earth News. I’ve got the magazine now for 30 years and several times a year they publish information on how to make your own solar panels, wind generators, hydroelectric and solar drying and dehydrators, and tons of great ideas.
They also have an extensive library, including e-books, of authors who have published articles in their magazine. Get their magazine, like I said I’ve been getting it for 30 years or more and I still eagerly await every issue. It’s all about sustainable living and doing things yourself. Plus it’s only about $10 a year subscription.
Look at their online site to get some ideas and maybe look at their alternative energy library. Whatever books or DVD’s I purchased from them have always been excellent

Ruth asks…
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.

You do not produce solar energy; it is free from the sun. However it can be converted to electricity using solar panels. If you check a picture of a satellite or the space station in orbit, you will see large solar panels to produce electricity to run the machines.
One environmental problem could be the disposal of old and derelict panels.
I came accross a new, proven and tested home made wind power system and solar power system which eliminates our electricity bills.

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

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.

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.

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.

Well it sounds like a logical answer, but due to friction and mechanical losses this would not work.

Your Questions About Solar Generators Hawaii
Mark asks…
Do you believe in climate change or a skeptic?
I’m a believer I have solar panels but I do think we need windmills
admin answers:
You have solar panels? Soalr thermal or Solar PV? Have you performed the math to dertermine how long it will take to get your money back or are you wealthy enough not to care?
Some areas solar PV can pay well. It depnds (HIGHLY) on you local electric rates and government rebates. Example Puerto Rico and Hawaii both have VERY HIGH electric rates ($0.30 – $0.40 / kWh). Solar PV pays realtively well even without utility incentives mostly because they have to import the fuel needed to run their generators and this is costly.
US Midwest with electric rates of $0.05 – $0.10 / kWh have a simple payback of around 30 years to install solar PV without including incentives.
Soalr thermal is a different story. Solar thermal can often offer positive economic return.
Wind can be good if you have a good resource. Not for all areas…
Best renewable resources are still hydroelectric and direct geothermal. Additionally you should look into ground source heat pumps. Long ROI (10ish years) but the base system (wells) have a service life of 200 years.
I am an Energy Manager. I design, install and manage these types of systems.
I have yet to be sold on the idea of AGW.
Climate change? Well, it changes all the time. I do not see the imperical evidence that it is happening in my region of the world. Yes, we use weather data in all of our designs as your systems will NOT function properly without it being included in your calculations. Data is upated annually and there is no discernable trend for the past several decades, hot or cold.

Please help with a project Solar wind and electricity!?
You are to determine a location and set up a home for solar and wind electricity.
1.) The home is 1500 square feet on one story. Determine the typical load requirement for a single family dwelling
2.) select a site (flat land enclosed by woods)
3.) minimal utility power is to be used and allowed for in your setup which includes a contingency plan for no sunlight
4.) explain your reasoning in all selection criteria
* include estimated cost of equipment and labor
admin answers:
1) You have to figure it out. If it’s in Hawaii, you probably don’t need heat, and can get by without A/C, too. In other places, more would be typical.
2) Your choice!
3) Since utilities are allowed, just to be minimized, I’d go with grid-tied solar electricity. The panels can generate 100% of average usage over time (unless this is Alaska or something). The grid is assumed to be reliable, but if there are doubts, I would go with a gas-powered generator for emergencies before I went with batteries to store electricity. The cost and upkeep of batteries would not be worth it unless they were going to be used all the time – typically, and off-grid arrangement.
Our house is 1900 square feet, single story. You can look at my profile and find out web page, with details on how much our system cost, which provides essentially 100% of our electrical needs. The link is called “Our Solar Panel Project” on that page. But we have gas heat. And prices have come down since we had ours installed, so you need to research current pricing.

Your Questions About Solar Energy Generator Suppliers
Michael asks…
I will like set up a solar panel to cut down my eletricity cost in Cameroon.can you allocate me a supplier?
I need a solar panel which can light up 4 full loaded 5 rooms appartment houses
admin answers:
Good idea going solar, i would suggest doing a google search, as their are many suppliers. Then you need to calculate the amount of wattage you think these apartment houses are going to require. Volts x amps = watts. If you are going to be off of the power grid, then you will need a way to store excess energy during good times,( lots of sun) in order to use it during bad times ( no sun ). Or see if you are able to sell your extra power back to your local power company, check because some companies do not allow this. You could even have a generator for emergencies if you go off the power grid. On final note, solar is a pretty sizable investment up front and your profits are seen mainly in the long run, but you will get energy savings immediately, but more likely those savings will go to paying off the solar panels also, you will need a converter to convert the ac (alternate current) produced by the panels into dc ( direct current ) which is used by the apartments. It will tie in to the existing electrical system in the apartments. I know germany is really pushing solar energy and they offer their citizens some pretty sweet deals to go solar. The companies are profiting from this so i would suggest looking for a supplier in germany, first. They may have better deals, or try bp (british petroeum) they have been in the solar business for awhile. I wish you success!

how do power stations make electricity?
ok i have the general idea of a power station they use friction to make electric and cole to make gas i guess the gas will cost money to make but what about electric?.
How do they make electricity?
Does it cost the energy supplier anything to make this energy?
is there a reasonable reason for high energy prices? or are they just making it for free and putting a price on it?
next they will tell us using a solar panel costs money to use :p
they say we are running out of resources thats why they want us to cut back on fuel consumption, with the prices raising it begs to wonder how it all works
admin answers:
Most electricity is generated with a “thermal power station” In these something is burned like: Coal or natural gas or heat is produced in some other way like using a nuclear reactor, concentrating the sun or getting heat from volcanic areas deep in the Earth. The heat is used to produce steam which is then used to turn a turbine that mechanically turns a generator that produces electricity.
But there are a few exceptions. Windmills and water turbines in a hydroelectric plant turn turbines directly without using steam or heat. Solar photovoltaic panels convert the sun’s light to electricity directly. There is also another process called magnetohydrodynamics that produces electricity directly without a turbine or a generator. This involves hot charged plasma moving past a magnetic field.
So there are several different fuels and several different processes that can be used to make electricity. What they all have in common is turning one form of energy into another. This is a business and it costs money to operate. Conventional power plants typically have a lower cost for the facility and an ongoing cost for the fuel that is used. Alternative power stations typically have a larger up front cost for the facility but little or no fuel cost. These would include hydroelectric, geothermal, wind and solar power stations. Both have maintenance costs but newer and alternatively fueled stations will cost less for maintenance.
Once fuel was cheap and now it is getting more expensive to supply fuel to older power stations. These older stations are requiring more maintenance so electricity costs rise. But electricity costs have doubled in the last 20 years. Petrol prices have gone up 4 to 6 times in that same period so it is all relative.
There are many factors that go into supplying electricity. Too many plants raises capital costs too few plants requires that electricity to supply the grid must be purchased from somewhere else at a higher cost. Electrical production must meet a constantly changing demand. There are electricity markets to supply too much and too little but very little of it can be stored at this time.
In some places rapid development requires expansion of the electrical grid in order to carry the supplied power to where it is needed. All of this costs money and if it is mostly invisible that is because someone is making it all work. Sometimes they are using your money to make sure it works.

Your Questions About Solar Energy Materials And Solar Cells
Charles asks…
what is the prospect of solar cells becoming really succesful?
Solar cells have two problems: 1 high cost 2. low efficiency What are the prospects that either of these is going to change ?
admin answers:
Pretty good. The real question is how long will it take for either to change.
First off, the efficiency of solar cells has already grown by leaps and bounds, with the disadvantage being that the methods with the greatest efficiency are very expensive.
There’s a couple of ways to improve the efficiency, perhaps without the associated increase in cost.
1) Increase the spectrum of light that can be converted to electricity. Currently, solar cells only convert a very small range of light frequencies to electricity. You could theoretically expand that range by combining different materials in a solar array, but if the crystal lattices of the different materials differ too much efficiency also suffers.
A new development, discovered during development of LEDs rather than solar cells, could expand the range of frequencies that could be converted to electricity without increasing the cost. Indium gallium nitride holds the promise of increasing efficiency to 50 to 70 percent (the best current solar cells run around 30%). The material is very defect tolerant, meaning the crystal lattices don’t have to match so precisely, decreasing the cost of production, plus it has a high heat capacity. Of course, a p-type version compatible with indium gallium nitride still needs to be developed, but if one is found, the efficiency of solar cells would leap while the cost would plummet.
2) Increase the number of electrons emitted in response to being struck by photons of light. Current solar cells can convert one photon of solar energy to one electron with the rest being lost as heat. Nanotechnology could increase that to three electrons per photon of solar energy, increasing solar cell efficiency to around 65%.

What is the best way to power my refrigerator in my rv when not plugged in?
I have the original generator that came with the rv but it does need some work. I don’t really want to have to run the generator just to power fridge while between places. The fridge is an electric fridge. I had thought about a solar panel or maybe just a smaller portable generator. Any ideas?

Newer RV refrigerators have a variety of of ways to operate now; propane, 12 volt, and 110 volt power. You can purchase a newer one online. I would recommend a 110 volt or propane combo refer. That way when you are using shore power you can use the 110 volt to power the refer or when you are dry camping you can use the propane feature which is very efficient. Or option b: you can purchase a generator (2800 watt or larger) to power it on 110 volt. Option C opower your 110 volt refrigerator with solar panels would require an invertor (2000 watt or higher) as well as a large array of solar panels drilled into the roof accompanied by allot of 6 Volt (golf cart batteries).

Joseph asks…
I need information resources for a hybrid solar/wind system?
I am building a small cabin (500sf) where grid power is not available. I need information not a salesman’s pitch. Anybody have any experience?? Thanks!
admin answers:
Your hybrid system would have to depend on the location where you are building your cabin. If sun is abundant all year around, solar powered system is advisable. Solar cells are not so expensive now as before. If the wind in the area is normal, there are inexpensive designs for a wind powered system. Both system has to store the power in battery banks.
Both system may easily be used in tandem storing energy to a single battery bank provided that your storage (battery banks) has enough capacity. Too much capacity would also mean higher cost. So the battery bank should just be enough to last until the next charging time (or cycle) normally every day.
Check your planned power requirement and match it with the system you might need.
For emergency cases, you must have a small engine driven generator set for lights and whatever emergency equipment you might have, just in case your batteries run out of power.
For suppliers of these system(s), you should check first for any local distributors and manufacturers closest to your cabin. It would make a difference at maintenance ( or other after sales services).
Jenny asks…
I wanna use golf cart batteries but which one?
I found this system on the internet
http://www.wholesalesolar.com/system/solaredge-8-trina-solar-panel-gridtie-system.html
and i know its already grid tied but still i wanna add in some batteries for emergency situations and people keep suggesting golf cart batteries. What voltage of golf cart batteries should i purchase? they keep saying that the voltage used by the solar panels, the batteries and the inverters must be the same but i dunno how to determine the voltage used by the solar panels in the link above.
admin answers:
Hey Stefan, actually, you can build up a, “hybrid,” solar/battery/grid tie system like you’ve described here with parts off the shelf, but I don’t think you’ll find that package already made up at Whole Sale Solar. You could give them a call and tell them what you want to do, they should be able to give you a quote on what parts are necessary and what the price would be.
First of all, all golf cart batteries are 6 volt, but the best one is made by Trojan. They are made in California, the model no. Is Trojan T-105. Each one holds 220 amp hours at 6 volts, has 3 cells, and weighs 80 pounds. We only have 4 of them in our hybrid system, really just enough to keep the basic loads in our home running overnight during power outages until the solar array comes back up in the morning. There are other golf cart battery makers, like Interstate for example, but you’ll get the best longevity from a Trojan. Our home has been powered by the wind and sun for 11 years now, we’ve been through lots of batteries in our day, trust me, the Trojan will hold up best. Look in the phone book for a place that sells and services golf carts, they go through batteries by the truckload, that’s where we found ours. There is a great book at the library on battery charging, I’ll list it below.
Our system uses a 1.4 kw solar array made up of Kyocera 120 panels, and has a Southwest Windpower H-40 900 watt wind turbine. The array and turbine all charge our 24 volt battery bank (using 4 golf cart batteries wired in series) through separate charge controllers. The solar array uses a Xantrex digital C-60 controller, and the wind turbine has its own, like most genny’s do. The heart to the system is the Xantrex SW-4024 sine wave inverter. It can stand alone, using battery power to feed AC power to your home, like ours did for years, or tie with the grid and parallel feed, like we have it doing now. The inverter has multiple connections, output, grid connection, generator, battery, and so on. It is programmable to sell/buy from the grid, and automatically switch to stand alone to keep your house running if the grid goes down, as long as your batteries have power. Since you’ll be charging them from the solar panels, this will work fine.
There are probably other inverters today that can do this same thing, but you have to have one labeled, “Utility Interactive.” A utility tie, or, “Grid Tie,” inverter only works with the grid, and a stand alone or, “independent inverter,” only works with the batteries and your loads, but an interactive inverter can do both simultaneously. I’ll warn you that they are not cheap, last time I checked that inverter was a little over $2,000 USD. This is why most of the grid tie systems do not use them, by listing a less expensive grid tie inverter, and then leaving the batteries off the parts list, they can reduce the total system cost by over 30%. It’s up to you what you are willing to pay for.
What I would do first is spend some time educating yourself on all of this. There is a great magazine that gets into the nuts and bolts of this stuff, and has lots of advertisements from vendors like Wholesale where you can shop for prices and kits. Also consider taking the time to get to one of the energy fairs listed in the back of the mag, we did 12 years ago, and this is where it got us today. The magazine liked some of our system so much they ran an article on our place several years ago. If you subscribe, you can check out articles and write ups on lots of peoples homes that work like ours. In the end, you might decide not to get involved at all, and that’s fine, but at least you will be well informed. Good luck Stefan, and take care, Rudydoo

Particularly well paid jobs will generally require a degree. Physics for research and possibly for planning, engineering for designing installations and possibly planning. Mathematicians or other physical scientists may be able to get involved in the actual planning. Non-scientists may be able to get jobs in solar companies in marketing, human resources etc. Physics or electrical engineering would be my recommendation.

Curious how much people think it would cost to get not only a septic system set-up but also some kind of power and gas supply in a rural field in colorado? Assume a trailer home is on the land for a house. (If that matters) 10 acres of land.

Solar panels are great for electricity,and are better and cheaper now,some on net from 250,Windmills also good make one via car generator,run cable from alternator to one -way diode to battery, use inverter from battery. Or use gas in a tank, delivered by lorry. Pond 100+ power50+ gas tank usually cheap as you buy gas from them.sy.

James asks…
is there an alternative for solar panels that can collect and convert solar energy into electricity?
A solar panel is a device that collects and converts solar energy into electricity or heat which can be used by (for example) nearby buildings. But is there any device that acts like a solar panel?
admin answers:
Besides the silicon type, there are a couple of types:
1. The reflector type of solar power, which uses a mirrored dish to focus sunlight to boil water to drive a generator.
2. Using sunlight to heat a thermocouple which drives a current.
Both of these are larger than your typical solar cell and are not really that efficient – yet.
A solar cell is the only thing that converts photonic energy into electricity, although they can be made of silicon and other materials.
