    someday, our folks are going to have to make their gas and oil from plants or mine it on other planets. Too bad I won't know what they come up with.

      Not exactly.

      Energy-to-mass ratios are horrible when seen through the lens of the delta V required to exit planetary gravity wells. Fuel from other planets will be Helium-3, as it is ridiculously valuable and has a high power release. Many speak of harvesting it from solar wind impregnated lunar regolith, but the cost of extraction from millions of tons of dust and pebbles is very high. It is more likely that the fusion fuel will be derived from tritium-3 degradation products through gaseous fractionation. The problem with the atomic route of acquisition is the multiple decade half-life.

      But, that is, some time off indeed.
