The Lifter is an asymmetrical capacitor which uses High Voltage ( > 20KV ) to produce a thrust. The Lifter works without moving parts, flies silently, uses only electrical energy and is able to lift its own weight plus an additional payload. The Lifter uses the Biefeld-Brown effect discovered by Thomas Townsend Brown in 1928. The basic design of the Lifter has been fully described in the Townsend Brown US Patent N°2949550 filed on Aug 16, 1960 and titled “Elektrokinetic Apparatus”, you will find in this patent the full description of the main principle used in the Lifter devices.
Today, more than 350 Lifter replications have been done successfully by many experimenters and physicists Worldwide ( see The Worldwide Lifters replications logbook ).
On January 22th, 2003, I have fully demonstrated with the 250 g weight Lifter “Maximus ][“ experiment, that a Lifter can be scaled up and also that such a device is able to lift 60 g of payload. It is now possible to build a VTOL craft which will use the Biefeld-Brown effect to fly silently and without moving parts ( see VTOL Lifter-Craft Mk III ) only powered by electrical energy…
