How interesting, in that the Usenet lights go out and the door slams
shut whenever speaking of seriously big and powerful ion propulsion
alternatives, that by rights of physics and of peer replicated science
should work, and should scale up without limitations.

Clearly those pesky MI5/CIA MIBs are in charge of this Usenet, and
they obviously do not like what some of us outsiders are having to
say.
