Why DARPA Is Betting a Million Bucks on an "Impossible" Space Drive
Posted on Monday, November 05, 2018 @ 16:49:25 GMT by vlad

Devices Anonymous writes: via PopularMechanics/By David Hambling
Agency responsible with filling the government's coffers with cutting-edge tech is funding a controversial drive that's based on unproven science.

The law of conservation of momentum says that a rocket (or anything else) can't accelerate forward without some form of exhaust ejected backward. But in 1998, a British engineer named Roger Shawyer announced the seemingly impossible—he had built a closed system that could generate thrust.

Twenty years later and many scientists still call the Shawyer's EmDrive impossible, but that hasn't stopped DARPA, the Defense Department agency that funds potential technological breakthroughs of all kinds, from putting serious money behind it.


An Irritating Anomaly

Here's how the EmDrive works. Imagine you have a truncated cone—a tube wider at one end than the other—made of copper. Seal it, then fill it with microwaves. Like other electromagnetic radiation, microwaves exert a tiny amount of pressure. But because of the shape of this device, they would exert slightly more force on one end than the other. So, even though it’s a closed system, the cone would experience a net thrust and, if you had enough microwaves, it would gradually accelerate.

Build it to a large enough scale and you could revolutionize propulsion...

Scientists pinpoint source of "impossible" EmDrive's thrust (Score: 1)

Via Newatlas.com: ..."When power flows into the EmDrive," he continued, "the engine warms up. This also causes the fastening elements on the scale to warp, causing the scale to move to a new zero point. We were able to prevent that in an improved structure. Our measurements refute all EmDrive claims by at least three orders of magnitude.” The team presented its results at this year's Space Propulsion 2020+1 conference, which was held online due to the pandemic....
