Inventor Roger Sawyer  want's to conquer gravity.  If the video above is legit, it looks like he is on his way. He has come up with a theory and working prototype and is looking to take it to the next step.  So far his theory has been scoffed at by the scientists and space agencies around the world.  This doesn't seem to phase Sawyer who also reports that the Chinese is working on a prototype of their own.

Looks pretty cool, hopefully this will shut Avery Brooks up.

Update

New Scientist has a much more indepth article here.
