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.
