Boyd Bushman

From Wikipedia, the free encyclopedia

Boyd Bushman (1928–) is a retired senior research engineer who worked for Lockheed Martin,Texas Instruments and Hughes Aircraft. Regarded as one of the inventors of the Stinger missile.

[edit] Antigravity claims

Boyd Bushman has claimed that Lockheed Martin has carried research on antigravity technology,specially gravity manipulation by means of magnetic fields, he even has stated that he carried experiments at Lockheed's White Settlement,Texas facilities,where is proven that magnetic fields affect the gravitational field and because of that ,bodies don't fall with the same acceleration,a result different from the classical experiments made by Galileo. He currently lives in Lewisville, Texas.

[edit] Parlor Trick

Mr. Bushman demonstrated a levitation experiment on film to several interviewers. He claims that 250 turns of wire plugged into a 120V 60Hz AC outlet causes a levitation effect that he does not fully understand. The part of this experiment that he does not explain is the material upon which the coil is placed. The surface the coil is placed upon is is a 1/4 inch thick aluminum plate. This experiment is commonly used in electrical engineering and physics courses to demonstrate electromotive force.

The alternating magnetic field inside of the coil induces a parallel circular electric current in the aluminum plate due to the changing magnetic field. When the magnetic field reverses in the coil due to the applied alternating current, the current in the aluminum plate continues to flow in its original direction. The two electrical currents then flow in opposite directions, both generating opposite magnetic fields. The opposite magnetic fields repel each other and thus forces the unfixed coil away from the aluminum plate. Nothing mysterious here. All squirrel cage rotors, used in induction motors (originally invented by Tesla) operate on this same principal. The difference between Bushman's experiment and the AC induction motor is in the motor the electromotive force is applied tangental to the axis of rotation of the rotor rather than parallel to the object carrying its induced current.
