Electrogravitics & Propulsion
High-voltage asymmetric capacitor effects producing measurable thrust and propulsive force. The Biefeld-Brown effect is experimentally verified and reproducible — the scientific debate centers on whether the mechanism is ionic wind or a deeper electrogravitic coupling.

Biefeld-Brown Effect Lifters
Thomas Townsend Brown
Asymmetric capacitors at high voltage experience a net propulsive force toward the smaller electrode. 'Lifter' devices hover using thin wire corona electrode + aluminum foil skirt + 20-50 kV DC. The thrust is REAL and VERIFIED. Debate centers on mechanism: ion wind vs. something exotic. Vacuum tests largely support ion wind.

Otis T. Carr
An alleged circular antigravity craft utilizing rotating magnetic plates, capacitor disks, and conical transducers. Otis Carr claimed a direct scientific association with Nikola Tesla. Legal records show Carr was convicted of commercial securities fraud in Indiana for selling unregistered stock.
