Fig. 6 CS lab w/horizontal lightning-ray.
Accurate depiction of the Colorado Springs experiment:
aurora gun, an animation from the film "Secret of Nikola Tesla."
The sound effects are notable: very, very accurate from what I
understand of this. They reveal a main key to the mystery.

"There is a method of conveying great power to ships at sea which would be
able to propel them across oceans at high speed. This method I conceived
between 1897 and 1899, and in Colorado Springs in 1899. I made experiments
along this line on a large scale. The principle is this: A ray of great
ionizing power is used to give to
the atmosphere great powers of conduction. A high tension current of
10,000,000 to 12,000,000 volts is then passed along this ray to the upper
strata of the air, which strata can be broken down very readily and will
conduct electricity very well. N. Tesla, 1935
ELECTROSTATIC HOVERCRAFT: force limits for a giant "lifter"
Assume 1-atm, max surface e-field of 3MV/M
C = farads/cc = 8.9e-14
E = energy stored per cc at max field = 4.01e-4 joule
F = mech. force to store E with work over 1cm = 4.01e-3 newton
F = surface lifting force on one M^2 = 40.1 newton = 9.0lbs
F = lift produced by 50ft disk = 1640 lbs
The above value is for ideal conditions: a permeable wire grid fuselage
with charged-exhaust reaction force only, and no aerodynamic lift. If
instead we used a solid fuselage shaped like a Frisbee or like an icecream
cone, perhaps Coanda effect would give us far higher thrust, much like
replacing a 1950s-era narrow-aperture turbojet engine with a modern
turbofan. But that ignores a fascinating possibility: active suppression
of normal gas-breakdown.
