More likely we'd build orbital satellite components on the Moon and launch from there to orbit the Earth in a position they can be lit more or less 24/7. The moon's got a 14 day night so that's an awful lot of down time for your very very expensive electricity generating equipment.
I know you're joking, but consider the novelty marketing potential.... Some day. Not in our life time, but some day. Maybe.
Except that we don't yet know how to make electricity by fusing He3. How many chickens we got in them thar eggs? Dunno, they ain't hatched yet.Digging a patch of lunar surface roughly three-quarters of a square mile to a depth of about 9 ft. should yield about 220 pounds of helium-3--enough to power a city the size of Dallas or Detroit for a year.
Flying on the moon? Read about it somewhere in some Popular Mechanics style futurism bull shit article. If you consider you'll weight 1/6 there but have the same muscle power you earned down here, why would you not be able to flap a set of wings and take off? Its worth a try at least, no?
With all that water, someone's going to make a swimming pool eventually. Imagine the splash you'll make with your precision cannon ball.
