I never think that I am going to die by accident, but if I were to die then all I can say is that I was wrong, and the hardened realists who kept their feet on the ground were right.

Helium-3 is made under extreme pressure and extreme heat. It was made when the moon ripped out of the Earth and flew into orbit around it, and continues to be made by solar winds down countless millions of years. Scientists can make only minuscule amounts, at a cost of billions of dollars, in the accelerator at Cern. Getting it from the moon – where it would be ‘mined’ from the dust and then heated to release the gas itself – would not be wildly expensive, nor beyond our ability. Helium-3 could supply all of the Earth’s energy needs way into the future by using fusion, which is both clean and safe.
