MW: No one has ever produce 1G similated gravity
habitats in space either-- but physics is physics. And
building a light sail would be a trillion times
easier than building a fusion rocket, or even a mass
driver, IMO. And in an earlier post, I proposed a 1
billion dollar annual NASA research program over the
next ten years to test and to build lightsails in
space.
