One of the ultimate dreams of humans everywhere is limitless, free energy. It's the ability to do the impossible: to pull power out of empty space itself; to create a device that spins ...

In major international tests, the physics-defying EmDrive has failed to produce the amount of thrust proponents were expecting. In fact, in one test at Germany’s Dresden University, it didn’t produce ...

Over the last few years, we’ve heard a lot about the EmDrive NASA has been working on at its Eagleworks lab under the direction of Doctor Harold White. Also known as the EM Drive, the EmDrive is based ...

After years of unwarranted hype and dubious experimental claims, the EmDrive, an “impossible” propulsion device that claims to produce thrust while violating Newton’s Laws of Motion, has received its ...

A lingering, improbable concept called the EmDrive says it moves itself without fuel. DARPA funding caused a fresh news cycle and drew attention to the inexplicable design. Momentum without a catalyst ...
