How about windmills built using manganese nodules harvested from the ocean floor? Still not exotic enough? Okay, we drill this hole down to the Earth's molten outer core in Tanganyika, use the heat of the molten nickel-iron that comes up it to run a giant geothermal power plant and the metal itself to build huge stainless-steel windmills...as the earthquakes produced by the atomic bomb we used to breach the ultra-hard shell around the outer core generate tsunamis that we can extract vast amounts of tidal energy from. Why screw around with asteroids when we can have so much fun right here on Earth? ;-) Pat

No one has yet figured out exactly what those things are that can only be made in space, but one of these days... Still, the far side of the Moon would make a great place to store nuclear waste. Pat

I'll go tell the folks I know using it that you've proven their systems don't work. -- Greg Moore Ask me about lily, an RPI based CMC.
