Skylon, Space X, NASA, India, China, Japan: what am I missing is why
non-chemical propulsion gets no priority (in order to make it real). Like
fission or fusion propulsion or space elevators.
As for an energy source on the surface, I'd but my bets on lava streams below
heat exchangers like Iceland does. Not windmills, nor powersats.
