"The hull can be made in a variety of shapes; sphere, football, disc, or streamlined rectangle or triangle, as long as these metal sheets, "are of considerable area and arranged along ideal enveloping surfaces of very large radii of curvature," p. 85. My Inventions, by Nikola Tesla."
"A short range machine can use a hydrogen-oxygen fuel cell to run a low-voltage motor to turn the generators, occasionally recharging by hovering next to high voltage power lines and using antennas mounted on the outer hull to take in the electricity."
"A machine built with a set of super conducting magnets would simplify and reduce electricity needs from a vehicle's transformer circuits to the point of flying along efficiently and hovering with little electricity."
"Actually Tesla’s “flying stove” used an electro-propulsion system, which was to be powered by external power stations and Tesla’s ‘wireless transmission of energy-system’ or with a power generator inside the craft."
"“The application of this principle will give the world a flying machine unlike anything that has ever been suggested before. It will have no planes, no screw propellers or devices of any kind hitherto used.
“It will be small and compact, excessively swift, and, above all, perfectly safe in the greatest storm. It can be built of any size and can carry any weight that may be desired” – The Sun, New York – ‘Tesla Promises Big Things’"

"The essence of electrogravitics thrust is the use of a very strong positive charge on one side of the vehicle and a negative on the other. The core of the motor is a condenser and the ability of the condenser to hold its charge (the k-number) is the yardstick of performance."

"the Electromagnetic force is (2.2 x 10^39) stronger than the Gravitational. To put it into perspective, if the energy required for mechanically lifting a block at a distance of one-quarter of a millimetre is, say X. If the same energy given to the block using Electromagnetic force, it could lift the block (5.6 x 10^24) km"
