I just tried to check out the US Patent Office's online system for patents by Boyd Bushman.

Why the fuck can I search just about every damn thing imaginable on a free web forum (i.e., HERE), but the Patent Office uses some special bullshit characters such as IN/ and blah$, etc.?

Anyway, here is some patents by Boyd Bushman:

Apparatus and method for amplifying a magnetic beam

A method for detecting objects while eliminating unwanted background

Boyd Bushman, who worked for Lockheed, Hughes and General Dynamics is one who has made many energy and propulsion breakthroughs in his career (he holds 26 patents). He invented a laser that dissociates air to produce propulsion (US Patent 5,542,247 and 5,680,135) and also has found a way to achieve flight using standing wave acoustics (Patent 5,511,044). Boyd was featured on the two-hour Discovery Channel special, “The Billion Dollar Secret” with journalist, Nick Cook, the author of The Hunt for Zero Point.

I don't know if the PERSON is Boyd Bushman, but the real Boyd Bushman has some serious shit behind his name.
