    In the book "LifeProbe" (which, by the way, has a sequal "Procyon's
Promise") the propulsion for Earthie ships and the LifeProbe was a
gravity-using drive. Matter was thrown into very small black holes
that had been given a high rate of spin. The matter would be whipped
around, given energy and thrown out again, and the ship moved via
one of Newton's laws. Michael McCollum explained it a lot better than
I did, but you get the drift.
