Lifter Version 1 & 2 Tests American Antigravity is currently conducting tests with the Lifter version 1 & 2 designs. The version 1 design features a single lifting-cell, whereas the version 2 design features a multi-celled lifting design.		Breakthroughs American Antigravity is working towards improving Lifter technology. We are achieving breakthroughs in the areas of performance, stability, reliability, noise-reduction, and power-use.

Currently, all American Antigravity video clips are in an mpeg video-format. Future plans are in progress to offer RealPlayer versions of these clips. Downloadable video clips are either 50 second 160x120 format or 15 second 320x240 pixel display -- this is due to mpeg format bandwidth limitations.
Lifter Version 1 [Facing] The Lifter v1 is shown in a facing view on 8-inch tethers during an April 4th test. This design was initially created by Transimensional Technologies in Huntsville, AL.
Lifter Version 1 [Angle] The Lifter version 1 is shown levitating on 8 inch tethers during an April 4th follow up test.
Lifter Version 2 [Angle] This overhead photo of the Lifter v2 was taken during operation to show the multi-celled approach to generating propulsion.
Lifter Version 2 [Dist.] This is a distance view of the lifter version 2 during operation. The Lifter is levitating on 4-inch tethers.
Lifter Flight Ceiling Recent tests by Rolland Swank and confirmed by Jean-Louis Naudin at JLN Labs and Stefan Kaechele indicate that the operation ceiling for the lifter degrades at 500 Torr (the equivalent to approx 4000-5000 m above sea level: 15'000 ft). Repeated tests indicate that voltage had to be decreased as pressure dropped due to excessive electrical arcing, and that operation ceased once the pressure dropped below 500 Torr. Special thanks to researcher Bruno Tilgner for this information. Some researchers have voiced concerns that this air-pressure limitation may indicate that the Lifter operates on ion-wind effects after all, however, American Antigravity's belief is that this test failure stems from a difference in required distance between the corona-wire and the foil as pressure decreases.
