http://www.americanantigravity.com - Dr. Mehran Tavakoli Keshe discusses antigravity and the MAGRAV technology that he's developed as a part of a novel plasma reactor system. Dr. Keshe is the founder of the Keshe Foundation, which holds a variety of international patents on antigravity, energy, health, and other devices.
In this interview, Keshe begins by describing his model of the "Neutron as a Plasma", and indicates that control over the plasma within the neutron leads directly to antigravity effects, and not any intermediary field generators such as electromagnetic coils.
Keshe additionally responds to a question about magnetic-gravitational to the Earth's gravitational field by indicating that it is not required, and that any body's position on the Earth is a product of the balance between magnetic and gravitational fields in that body and the Earth itself.
Although Dr. Keshe does not describe a mechanism for these antigravity effects, but indicates that he has blueprints for the MAGRAV device available to any government that comes forward to claim them. This, he states, is designed to assist with a smooth transition to Keshe technologies and avoid disruptions to society that might otherwise arise.
For individuals interested in replicating antigravity experiments based on Keshe technology, he suggests visiting the Keshe Foundation website and reviewing the international patents online there.
