LOL Suckrip!
One thing wrong with that though........if partciels are attracted INTO the impulse engines form the back, they'd be tranferring their momentum forwards, which would actually give the ship forward thrust and not reverse thrust. For reverse thrust to happen you have to have thrust exhaust going to the front of the ship.
But that is a novel idea.....
Actually, I don't see why our two ideas couldn't be COMBINED........that the impulse engines can suck as well as spew with re-directed exhaust, but just not at the same time.
Sorry for hijacking your thread, A.
