No matter what happens from here, Roger Shawyer can feel at least a bit of vindication. There's no way to know whether his potentially world-changing new fuel-free thruster called the EM Drive will be ...

At this point, the EM Drive will be important -- if not for revolutionizing space travel, then at least for dramatically illustrating the difficulty of taking accurate force measurements at extremely ...

This update revisits the controversial EM Drive, once hailed as a potential fuel-free propulsion breakthrough. Recent German experiments, however, suggest that any observed thrust may simply be ...

Who needs the laws of physics, anyway? Not NASA. At least, that is what a new peer-reviewed paper indicates. The paper discusses what was a fuel-free rocket engine, which tests now show works. But how ...
