Solar power is extremely inefficient, and I think I read that it takes like 7 years to create the amount of energy it took to make the panels. And hydrogen is weak, too. Hummer made a hydrogen H2 and even with 3 big tanks in the back it could only go 60 miles, yep thats the future.Sparkfist wrote:Well everything cost fresh water, so to claim that it cost fresh water is like saying food cost money. Also there have been plans for awhile that if we switched to a hydrogen based economy local fuel stations could use solar power to crack hydrogen and oxygen apart, it doesn't require too much energy to do just a lot when you need to fill a car. Cold fusion is a myth, and until the Brits can get that nuclear reactor outputing power rather then drawing it in we wont have it.
I say if not cold fusion (I know its far in the future), maybe super high capacity capacitors that would charge from fusion power plants.
