Are we that far off from the ability to go 100% solar energy? Electric cars are developing now and have been around for years. I drove one in about 1980 ( I forget the exact year). I made my own solar heater sometime in the 80's. You can store the energy long term, I've had my tractor battery stay up all winter . Is anyone working on better storage medium? I have heard before how much solar energy hits the US in a day but don't remember the figures. Anybody out there know? If we could quit buying foreign oil I think most of these troubles with the Arab countrys would dry up. And the world would be much better off , pollution , wasted dollars,etc. What do you think?
