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 ...

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 ...

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 ...

A new theory of inertia could explain how NASA is generating thrust with a new drive design, and may even show them how to make it more powerful. Share on Facebook (opens in a new window) Share on X ...
