Yeah, um, not so much.
Probably not going to happen, given the immense cost to benefit ratio. Who's going to fund this, considering that no one is even willing to pay for a serious potential impact project here on this planet?
Clean fusion power, enough to power the Earth for probably 10,000 years exists on the Moon. This is of course assuming that we can get a fusion reactor running. If not, then Helium-3 becomes basically worthless.
Nah. There's no money in an Antarctic settlement, while there's potentially unlimited fundage in a Moon settlement.
