> I imagine unlimited cheap energy would help facilitate moving us off this floating rock we call earth. With a working small scale fusion reactor we could colonise the entire solar system, the raw materials are all out there but energy is always one of the main issues. I remember reading back in the 80's a plan for extracting metals, creating metal foam that would float and then dropping them into the ocean (some would be lost to rentry heat but it was a tiny percentage) where a drone ship would sail out and tow them in. I would love to see something like that in my lifetime.
