That was a very interesting, TinFoilHat. One thing people don't seem to realize is if someone does come up with a He3 reactor it would be far, far easier to use earth helium than moon helium. The concentration of He3 in lunar helium is only 10 times greater than in earth helium and is much more than 10 times more difficult to obtain. On earth helium can be obtained where it is trapped in natural gas deposits. Some natural gas deposits are up to 7% helium so there is no great shortage of it yet. If we wanted to could extract He3 from commercial helium today that goes into party balloons and scuba tanks and just hang onto it on the off chance He3 reactors become practical.
