Helium-3 (He3) has potential to be used as fuel in future
nuclear fusion power plants. It would produce a clean fusion
process, leaving little of the radioactive waste that plagues
nuclear fission. But Helium-3 is found rarely on Earth and is
therefore worth $16 million dollars per kilo. With prices like
that, resource extraction on the Moon all of a sudden becomes a
fairly reasonable economic activity to pursue. Several governments
have subsequently signaled their intention to go to the Moon to
mine helium-3 as a fuel supply.
Is this a potential and viable solution to our energy problems? What are the pros and cons?
