|World Power Grid|
Buckminster Fuller had a plan for a world power grid run mainly off wind farms- see, the wind is always blowing somewhere within a 500-mile radius, so if you link all the world's power grids together, they support each other and run forever off natural global air currents for free. You fit private homes with wind generators to take up the slack, and when you're not home, it puts power BACK into the grid and MAKES you money, how good's that? Trick is getting the world's governments to agree that UNLLLLIMITEEEEDDD POWWWWWWERRRRRR is a good thing, even if they have to share, and getting it past the petroleum and nuclear entities. Sigh.
