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.

Lisa asks…
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.

Your Questions About Solar Generators For The Home
Robert asks…
Build a solar or wind propelled generator?
I want to know how to make a solar or wind propelled generator? First if i can make a solar and wind propelled generator and combine them to work at the same time. The solar panel can be around 12 volts. I just want to do this as a home project. I don’t want extreme power out of this. I am young but have a lot of experience with building electronics so keep it simple enough for me to do it.
admin answers:
Well i dont know much but i hope this will help, i whould imagine for the wind power you whould need the light propeler to be somehow conected to a magnetic generater. And for the solar power, well i dont know much about that but i hope to find out soon.
Sharon asks…
How many solar panels does it take to run an A/C unit? Also, How many batteries in an array?
I was wondering how many 700 W solar panels it would take to run a household A/C unit. Also curious how many batteries it would take to keep A/C running in inhospitable environments. Would a 3500 W inverter be enough if it were to run 220 AC?
admin answers:
Here we are doing the math of two facts to multiply or divide, to find the third, and you don’t give enough to make up the equation!
My 2.5 ton unit needs 220 VAC at 5 KW for the heater coils, and 3.5 KW for the cooling and fans, but, in electricity, we are always having to discriminate between inductive loads (transformers, oven coils, heater coils) and other uses, like lncandescent lighting.
To run my HVAC unit, in my 1,000 square foot home, would demand a10KW unit, and the 5200 watt (5500 watt Surge rated)
would not work. A generator simply stalls out under load, possibly smokes the generator electrics, while a solar unit and batteries can reverse potential under severe load, and explode!
The surge rating for my HVAC unit is 3X higher, (the Switching Load), for either heating or cooling. When figuring out the generator load for an emergency generator, for warranty purposes, they demand we install a generator with a ‘surge’ power rating triple the start-up load of our equipment, and that is the way to try to load your Solar panel, also!
Now, go to the hardware store, and get a booklet or pamphlet about emergency power generation, and look at the descriptions of the generator start up power capabilities for the ‘switching loads’!

Your Questions About Solar Energy For Kids
Mark asks…
What do you think of creating your own wind and solar energy?
I stumbled across this site that shows you how to make your own windmill and solar panels… earth4energy.i8.com
Do you think it’s a good investment? If it works I’m a welder and I could pop a whole bunch of windmills up easy but thats only if this works.. What do you think?
admin answers:
Wind Power wouldn’t really benefit you unless you have a lot of wind near your house. Also Wind Turbines cause a lot of noise pollution (annoying noise) and kill birds (I’m not kidding, migratory birds get killed when they get near the turbine because they get stuck). I wouldn’t invest in wing power unless I live near the beach where there is a lot of wind or a place with a lot of wind.
It will take you about 10 years to get back the money you have invested in a solar panel. Keep in mind that the days get shorter during winter until the winter solstice and there is less sunlight. Solar Panels absorb very little of the energy of the sun.
Keep in mind what I said before investing in solar and wind power. I suggest waiting till the solar panel cost gets cheaper till you buy.
Betty asks…
Can you get solar energy when your renting a town house in Las Vegas?
Or do you still have to pay an electric bill with the energy company?
admin answers:
It would cost a substantial amount to eradicate an electric bill. Keep in mind that most states have laws regarding housing, specifically anything that is physical attached becomes the property of the property owner. This would apply even to something as simple as an under counter can opener.
If you want to maintain ownership get it in writing.
You will also need permission to make an addition to the property. A homemade window box collector would not need attaching necessarily but fits into a partially open window. Search it like

Your Questions About Solar Energy Environments
Susan asks…
What are the ways that Solar Energy is more environment-friendly and feasible than Nuclear Energy?
The more, the better. The arguments should be at least remotely feasible. I’m looking for ecological arguments why Solar Energy is a better alternative than Nuclear Reactors.
admin answers:
They both have their place, so if you’re planning for a debate, you’ll have to take this into consideration. Your argument should be for solar, but not against complete replacement of nuclear. If you argue the latter, you’re sure to lose, unless your opponents are incompetent.
But to answer your question directly:
– Solar can provide heat directly, without being converted to mechanical motion and then electricity. It is thus more efficient at heating (say) water.
– Solar scales down well, so a single house system can be feasibly installed. A nuclear reactor needs at least an apartment-building load to be feasible. And they would only do that in Russia, because
– Nuclear reactor technology can be used to breed weapons materials. And even if you couldn’t construct an A-bomb, if you could order fuel for your home reactor, a bad person could grind it up into a fine power that would make a hazardous mess when blown up in a public place.
– The nuclear waste and radiation hazard also make nuclear unsuitable for single-home usage. These are not as much of a problem for a centralized plant.

Thomas asks…
How does solar energy effect australia?
For example, how does it effect the environment?
How much solar energy is used in australia?
admin answers:
Without solar energy there would most likely be no life on Earth let alone Australia.
There is an argument that all energy except geothermal and nuclear derives from our Solar source.
As Australia is closer to the ozone depleated South Pole the sunlight there is more intense than in other places in the world. As a result skin cancer rates can be expected to be higher.
You might wish to narrow your question a bit.

Your Questions About Solar Generators For Home Use
George asks…
How does an electric inverter used at the tail end of wind generator stay in phase with the power company.?
how does an electric inverter used at the tail end of either home solar panels or wind generator stay in phase with the incoming household current. It would seem to me that if the phase was just slightly out of time with that from the power company, much of the power produced would be lost.
admin answers:
The best inverters use a pulse-width-modulated output and a low-pass power filter for the line frequency (60 Hz or 50Hz). The high voltage DC input is modulated at a rate in the 20-40 kHz range or even higher. The modulation is controlled directly by the line to which the power is fed into. Some of these inverters can run in the high 90% efficiency range.
For the PWM inverter to work, whatever the output of the generator, it must be converted (any phase, any frequency, or even DC) to high voltage DC. This can be done independantly of the line frequency or phase.

How to set up a wind power system in the home?
Hi yahoo answers tell me the procedure for setting up the power system in the home..
admin answers:
Electricity can be generated by building Windmills which rotate when there is wind blowing and generate electricity through a generator.Nowadays, the Technology is so improved that we can build our own Solar Panels or Wind Power Generators at home with materials available in our local hardware stores to generate electricity. This way we can eliminate or reduce our Electricity bill.

Steven asks…
Is the usage of Wind Powered Generators & Solar Generators Illegal in Singapore?
I’m planning to buy either a Wind Powered Generators, Solar Generators or a Hybrid Generator to be more “Green” & at the same time save on electric bills… I’m able to install such a generator on my home…
admin answers:
Its sad that Singaporeans should ask such questions. We are so timid. At the very worst you get a fine for installing green equipments. Take a MRT ride where you can see many terrace houses. You will find many with solar roofs.Their owners are not languishing in Changi prison. As for wind power, Singapore is not windy whole year round. Best stick with solar panels.
Maria asks…
Can a solar generator and panels be hooked up to a trailer home on a rural field?
I plan on moving a newly manufactured trailer home onto around ten acres of rural field. I need a source of power, i have found solar power can be fairly inexpensive in the long run, though i have been told trailer homes cannot be hooked up to solar generators and panels. Is this true? if not how do i hook six 80 watt panels up to the trailer home?
admin answers:
USA Yes you can, unless there is a local municipal ordinance against it – which I have never heard of. But, why 80 watt panels? The industry standard is 230 watt. Six 80 watt panels won’t even power a normal refrigerator (they’re usually 700 watts). If you have all the parts and equipment, or if you can get them for free, then it is worth it to hook them up. But, if you have to buy the items, the average cost is $5 per watt, which is $2400.00 for a 480 watt set up. Generating 480 watts per hour will total 5000 watts on a good day. That is about $0.50 worth of electricity. At $0.50 per day, it will take you 4800 days – that is more than 13 years – just to break even.
You should add up the power requirements for everything in the home that might be used at the same time – cooking, refrig, cooling or heating, well pump, lights, TV – and base the size of your system on how many watts you will need. If you can, go more than what you need and sell the extra to the utility. They have to buy it from you.

The Basics On Solar And Wind Power
Energy is quite literally what makes the world go around, and without the continuous supply of energy that is taken for granted on the whole, everything in life would dramatically and quickly come to a halt. Solar and wind power are two incredibly important and highly significant factors in this matter, and both should be properly and thoroughly understood and considered in order to gain a respective ideal on the subject issue. In order to truly gain a proper understanding on solar and wind power, all key issues should be taken fully into consideration.
What Are Solar And Wind Power?
Solar and wind power are alike and different in many ways, and the similarities and differences of solar and wind power should both be properly learned and understood. First, the term solar power is used to describe the number of methods which include the harnessing of energy from the sun. Solar power has been around and been considered and used for centuries, although it has truly only come into completely widespread use as of particularly lately.
Solar energy is energy which is derived directly from the sun, and passive solar heating involves that of the design of homes and buildings in order to make use of direct sunlight for that of heating purposes. Most of the solar energy today is harnessed as heat or electricity, and the most common uses for solar power involve that of: solar design in architecture, solar heating systems, solar cooking, solar lighting, and more.
Wind power is literally defined as the conversion of wind energy into more useful forms, which is usually that of electricity using wind turbines. Most of the modern wind power is primarily generated in the form of electricity by converting the rotation of turbine blades into electrical current through the means of an electrical generator. Wind energy is incredibly abundant, widely distributed, clean, and renewable.
We as a people have, in fact, used the wind as an energy source for a particularly lengthy amount of time. In fact, the electricity-generating wind turbines were invented in the United States and Europe in the late 1800s. Wind power didn’t used to be much of a topic of interest, however as of recently there has been a sudden increasing interest in it. There are two primary reasons for this, which are: one, most electricity generated today uses non-renewable fuels such as coal, oil, and gas and secondly, advances in wind power science and technology are reducing the cost of wind power to a point where it is actually becoming competitive with many other energy sources.
