Blue Sky Limousine

Recently I mentioned how underwater turbines seem like a good idea. Yesterday I watched “Life After People,” and it presented the likely scenarios of how things will fall apart if humanity suddenly disappears. It said the gas-powered electricity-producing facilities would shut down in a matter of hours, nuclear power plants would automatically shut down pretty soon as well, and wind turbines would grind to a halt when no longer kept well-oiled. However, the power-producing Hoover Dam is supposed to last for a couple of years (maybe more) on its own, with no maintenance.

So obviously there’s plenty of power in nature, especially in bodies of water moving around. If we could harness that in a major way, we’d be well off!
