Re: Exploiting space; the Man IN the moon


He-3 is a very rich fuel, it should be cheaper per energy unit to ship
He-3 from the moon than coal from the earth.

What power plant currently uses He-3 to run? What's the use of a rich
fuel we can't use?

Getting -anything- from the Moon to the Earth is wildly expensive.
Digging up coal and shipping it down the road a few hundred miles is
orders of magnitude cheaper.
