BTW my theory on the He3 origin is that it was brought to Earth by the meteorite that created the Hiawatha Crater. This meteor also triggered the opening of a rift in the crust from which lava flowed forth carrying the He-3 with it. The meteor acquired it's He-3 over millions of years of Sun grazing orbits in space. On one of the trips around the Sun it managed to impact the Earth. The sun grazing orbits did two things:- 1) They exposed it to high intensity He3 bombardment. 2) The object got hot enough for the He3 to diffuse into the core of the object. Regards,
