Jupiter's atmosphere is about 25% helium. And then there's the other gas giants, and the sun itself (also about a quarter helium) We risk running out of cheap helium. But if you are willing to pay infinite money there is near-infinite helium | ||

Right now, even with infinite money, you have no way to extract helium from Jupiter and return it to Earth. (To say nothing of the Sun!) Maybe with a couple hundred more years of technological development... Our moon itself is said to have ~1M tons of very valuable Helium-3 in surface deposits, but even that's nigh impossible to harvest commercially right now. | ||
