A company in the US claims to have created more than 1 gravity of thrust using electromagnetic fields. Worth noting, even they are not entirely sure why it works. They claim that it seems to violate several laws of physics. They also say that they have observed objects maintaining thrust days after electrical input was cut off, so long as the object still held a charge.
