Now, see, this is why we focus on what it does do rather than trying
to palm it off as doing what it can't. Example: I recall another
discussion in the not too distant past (though it might have been on
another list), about how one could possibly slightly improve (make
lighter per KW output) nuclear fission reactors as used to power ships
of the sea, then use them to power particle accelerator engines to get
very low fuel fraction Earth-to-orbit rockets, which should hopefully
be cheaper because most of their mass is reusable. Problem is - or
maybe now, *was* - that particle accelerators cost many billions and
are about the size and mass of a good sized town.
