For nearly 20 years, scientists have debated the viability of an EmDrive, a hypothetical type of engine that could propel a spacecraft without the need for any fuel. Now, a team of German physicists ...

On 17 November 2016, a team of engineers from an experimental research group (nicknamed Eagleworks Laboratories) at NASA’s Johnson Space Center published the results of a test purporting to ...

George Hathaway provides a detailed analysis of the EMDrive and the recent peer reviewed research paper that measured some thrust and tried to eliminate sources of ...

A radio frequency (RF) resonant cavity thruster is a proposed type of electromagnetic thruster. Unlike conventional electromagnetic thrusters, a resonant cavity thruster uses no reaction mass and ...

The "EmDrive" claims to make the impossible possible: a method of pushing spacecraft around without the need for — well, pushing. No propulsion. No exhaust. Just plug it in, fire it up and you can ...

Given fuel usually makes up the majority of the mass of any spacecraft trying to break the bonds of gravity, developing propellantless propulsion systems might be the key we need to really open up ...

In 2014, no less an authority than NASA proclaimed in peer-reviewed papers that it was getting mysterious thrust from the EmDrive, a strange, brassy trumpet of a thing that its creators claimed could ...

Researchers at NASA's Eagleworks advanced-propulsion lab have been working on a technology that can theoretically bring humans to Mars in just 70 days. The rocket propulsion engine known as EmDrive is ...

More experiments on the much-overhyped EMDrive continue to prove absolutely nothing except that it’s easy to create ambiguous results if you’re sufficiently sloppy with your experimental design.

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 ...
