I bet that if one simply suspended the dean drive assembly from a rafter using a long spring, no net motion would be seen. I will say that with Non-Inertial Navigation, after talking with the inventor on a video conference, my instinct was that he was sincere but misguided. After watching the asymmetrical capacitor video presentation, my instinct is that the inventor is a complete huckster, and does know better, as I watched him deftly include everything likely to impress the relevant audience, up to and including perpetual motion, free energy, and alien technology. But no warp drive. As for Dean, I have no idea, but tend towards pure huckster. Joe Gwinn
