Rather than Aether thrusters... suppose we're living in a cloud of dark matter right now. How to apply a thrust? Maybe electromagnetically. One thing that I've never heard that anyone investigates: vacuum propulsion by fluid analogy to smoke-ring launchers! With smoke-ring launchers, the device uses an oscillating piston to draw in air from all directions, then periodically emit a high-speed "air glob" in just one direction. It can thrust itself along, even though the piston is pure AC. The "AC" waveform is spikes or a sawtooth. It's a DC pump that relies on nonlinear turbulence phenomena for its rectification: in some Reynolds Number regions, sucking is not the same as blowing. Our goal then becomes to find an antenna which, when given a strange AC waveform, will launch out "smoke rings" made of dark matter when pulsed in a certain way. Possible test: build a small copper tank that looks like an actual smoke-ring launcher (with a hole in one end,) then put a one-turn coil inside it and feed the coil with unipolar spikes: capacitor discharge with series resistance to create neutral damping. But maybe Dark Matter is neutral. In that case we'd want to add a strong e-field; perhaps charging the metal tank negative in order to attract positive-charged Dark Matter particles to the interior. Total rumor: Tesla bounced electromagnetic "smoke rings" off the moon, but found that their energy increased with distance travelled, and when they return to Earth (in Siberia) they knock down forests but without leaving any trace that a meteor caused the blast.
