So as a kid you watched Star Wars and since then you’ve wanted your very own Landspeeder. The problem is, how to make things hover without using fans, magnets, or special effects? Well, a maverick UK scientist may have invented a way to do it. By harnessing microwaves, and a loophole provided by special relativity, Roger Shawyer has developed a new kind of "relativity drive" that may be the future of space propulsion, and perhaps even terrestrial hovering cars and aircraft. He’s received high-level interest from the UK, US military, and the Chinese and hopes to test it in space in a few years.
