NASA’s ‘Impossible’ Space Engine Tested—Here Are the Results
The first independent tests of the EmDrive suggest there’s a mundane explanation for the wildly controversial device.

“The ‘thrust’ is not coming from the EmDrive, but from some electromagnetic interaction,” the team reports in a proceeding for a recent conference on space propulsion.

The group, led by Martin Tajmar of the Technische Universität Dresden, tested the drive in a vacuum chamber with a variety of sensors and automated gizmos attached. Researchers could control for vibrations, thermal fluctuations, resonances, and other potential sources of thrust, but they weren’t quite able to shield the device against the effects of Earth’s own magnetic field.

When they turned on the system but dampened the power going to the actual drive so essentially no microwaves were bouncing around, the EmDrive still managed to produce thrust—something it should not have done if it works the way the NASA team claims.

The researchers have tentatively concluded that the effect they measured is the result of Earth’s magnetic field interacting with power cables in the chamber, a result that other experts agree with.

“In the EmDrive case, interactions with the Earth’s magnetic field seems to be the leading candidate explanation of the small thrusts seen,” says Jim Woodward of California State University, Fullerton.Woodward has theorized a propulsive device of his own called the Mach Effect Thruster, which the Dresden group also tested.

A wonder how much money has been wasted on this Zarkovian device so far.

I don’t think that says it is producing no thwust.

You must have missed this sentence:

“The ‘thrust’ is not coming from the EmDrive, but from some electromagnetic interaction”

Doesn’t seem to mention the result of this test.

If Zarkov himself could attract such funds, he’s have landed his Land Rover on Mars years ago.

It probably worked, and the Dresden group are now on their way to Sirius.

“When they turned on the system but dampened the power going to the actual drive so essentially no microwaves were bouncing around, the EmDrive still managed to produce thrust”

So the drive was still producing thwust when powered up but turned off.
So producing thwust all the time when powered up.
Presumably producing more thwust when turned on though.

They were mistaken when they said: “…the EmDrive still managed to produce thrust”, since the thrust effect had nothing to do with the “engine” itself.

Surely it would be pretty easy to calculate the thrust due to the Earth’s magnetic field, and deduct it from the measured thrust.

Perhaps not. We are talking extremely low, barely significant, readings.

I think the release has been intercepted and interpreted by a ‘journalist’ thus rendering it useless.

Well I’d say if maximum possible thrust due to Earth MF was > minimum possible measured thrust, that was pretty good evidence that further investigation was probably a waste of time.

They’re saying it is some electromagnetic effect of the current in the wires leading to the device.

For a quick check, put a magnet next to it and see what happens.

might be saying any desired thrust effect was swamped by thrust from another effect (produced by earth’s EM field), and given sensitivity of instrumentation the desired thrust effect (if it exists at all) was so small as to be useless.

Id like it to be tested out in space.

Just to be sure.

:)

I hope you all appreciate that this whole thing was an exercise in futility.

Like testing the clinical effect of a homeopathic medicine, the longevity of a perpetual motion machine, or a method of squaring the circle.

Maybe another way can be found to get it to appear as if its doing something.

Only if the underlying assumptions of basic physics are correct.

I want to see it tested in space, just to make sure.

Biases might exist for wanting such devices to work as it means another method of space travel.

On the other hand, biases might exist for wanting such devices not to work, because it would mean that all of science would be wrong.
