From a discussion on Slashdot today:

I’ve come up with a way to reduce– perhaps even eliminate– our dependence on foreign oil as an energy source. As more and more civil liberties are trampled upon, faster and faster will the Founding Fathers spin in their respective graves.

If we attach magnets to each Founding Father, then wrap copper wire around each of them, we should have a potentially unlimited energy source. Well, at least until the Libertarians get elected in significant numbers– so yeah, come to think of it, it truly is unlimited.
