the introduction from the page;
============================
Aerospace propulsion technology to date has rested firmly on simple
applications of the reaction principle: creating motion by expelling
propellant mass from a vehicle. We can do better.
A peculiar, overlooked relativistic effect makes it possible to induce
large, transient rest mass fluctuations in electrical circuit
components [Woodward, 1990; 1992].
Such fluctuations may be combined with a synchronized, pulsed thrust
to greatly increase the acceleration attainable from a given amount of
ejected reaction mass.
A yet more innovative implementation of the effect suggests it may be
possible to make engines that accelerate without the expulsion of any
material whatsoever. These "impulse engines" are achieved without any
moving parts (in the conventional sense).
The concepts involved are supported by experimental results already in
hand. Moreover, due to the nonlinearity of the effect, Morris and
Thorne's [1988] traversable wormholes and Alcubierre's [1994] "warp
drive" may be attainable with known technology (while remaining fully
in line with the established laws of physics, despite their "Star
Trek" nature). Here, however, I deal only with impulse engines.
