If we're going to mine someplace in the solar system for 3He, I'd like to see it done on a (currently hypothetical) "Planet X", a Mars to Earth sized planet 100+ AU from the Sun. It could be cold enough out there for a bit of helium to remain bound over the life of the solar system, but it would be much easier to take off from again than, say, Uranus. And presumably with D3He fusion one could get out there with a fusion rocket. |
