You could very appropriately call this the "cockroach of the physics world." NOBODY in mainstream science is taking this seriously. Basically a man named T. Thompson Brown did experiments using a capacitor and dome of aluminium foil. When charged with electricity the dome became lighter and lifted off. WELL, the boys over at American Anti-gravity.com have replicated his experiments and came up with these triangle shaped craft, that do, when charged with electricity lift off the ground and hover. Cool stuff! This isn't something only pointy headed scientist types can do. ANYONE can replicate their work, provided they know how to harness electricity (it takes some serious voltage/wattage) and can afford the components. Anyway, I'm going to provide a link so all can go to the site and see for themselves.
