Going Solar electric - your input please?

The last I had heard, it sounds like a good idea, but just one of the batteries would not be powerful enough to power but just a few things for a short period of time. But they would however be able to be linked into others in a row to make one large battery. But then the costs go up also. I think they are on the tight track, and soon there will be a true breakthrough in battery technology that will be the true saving grace to the world. They are very close, just not quite there yet.

Supercapacitors.

So, new thing on the scene is "gravity generators". All surplus energy is used to wind a series of gigantic counterweights. Then when you dont have energy they wind down and turn an alternator by themselves. Looks pretty promising.

Very large and efficient flywheels?

"Free energy"... Second Law of Thermodynamics, everyone?
