EM drive tests appear to show that it may actually work.



"The drive, which has been likened to Star Trek’s Impulse Drive, has left scientists scratching their heads because it defies one of the fundamental concepts of physics – the conservation of momentum – which states that if something is propelled forward, something must be pushed in the opposite direction. So the forces inside the chamber should cancel each other out."


If this is true, it could be a huge step forward in space travel.

It is a terribly written article.  The only new information is that some unspecified tests were conducted in Dresden.

do you know how is this working?

technicals details?

I know how it's working and I posted most of the technical details on this site nearly 5 years ago.  What they're showing to the public is only a small portion of the device.  What is being shown is nothing more than a modified cathode ray tube.  Seek and you shall find.  Also note, the technical details can almost be found in your username of "madama".  What a coincidence!

It is my position that Shawyer is wrong.  This is what Shawyer claims:  E/M waves bouncing around a metal can that uses a near vacuum dielectric has E/M wavefronts that propagate close to the speed of light.  When those wavefronts hit a metal wall, Faraday induction occurs resulting in reflections.  Shawyer claims that by tapering the can, the net force of the reflections in one direction along the central axis will be different than in the other, giving rise to a net accelerating force parallel to the central axis.  Various SMEs who have examined his math in detail assert that he misaccounts for the forces on the tapers and so his idea is one of GIGO.  NASA tests should be complete this year that competently isolate sources of experimental error to see once and for all if there is something to Shawyer's claims or not. 

Personally, I chalk Shawyer's ideas up to something that belongs in the Museum of Unworkable Devices.  I think his idea is akin to propelling something by placing a laser in a cavity with a highly reflective mirror at one end and a highly absorbant material at the other.  Or to put it another way:  a fan in a sailboat blowing on the sailboat's sail.

I agree with your analysis above.  I must say though, the effect does have something to do with the vacuum.  This leads to questions, such as do they even have the slightest idea to what is going on, or is it more misdirection for the general public?

How does this work?
Probably due to a mass of the boat much bigger than the mass of the expelled air...
Interesting - can greatly increase the efficiency of the jet engine!

It's more than likely due to a combination of phenomenon.  I say there's a potential difference in the air pressure that is at play.  I won't need to expand on this if Madame or someone else reports back with the technical details I posted 5 years ago. 

My ex g/f deleted all of my research papers and I can't find the publications on the internet that may be related to this phenomenon.  If my memory serves me correctly, the publications were referenced in the papers written by Ioannis Xydous which were titled, "the secrets of the electron-positron pairs".  It should be fairly easy to find once I decide to search for it.

In addition to the potential difference in air pressure, angular momentum is at play also.

its is quite obvious that there is some pressure difference on the sale.
What is not obvious, is why it manages to go forward, even though it is supposed to jerk backward  due to the reaction of the boat.

The QV really doesn't enter into the claims as Shawyer makes them.  Special relativity does though.

I may be wrong but I am fairly sure I read that the actual thrust from one of the devices under discussion was measured as a few hundred millinewtons. It would take several weeks to accelerate a bicycle from 5 mph to 10 mph.

Brown-Biefield effect. There's a thrust in a capacitor toward the negative charge plate too. The plasma produces a magnetic field.

Shawyer claims that using superconductors the Q of the cavity can be greatly increased (it can) and the specific thrust will also then increase (0*N = 0).

Yes, I was not too impressed with the way it was written either.  At some point in the article, a guy is quoted saying something like...well...we can not really confirm nor deny if it works from these tests...which does not really jive with the whole upsetting of the laws of conservation of energy thing.

I just copied and pasted the headline from the article for the topic title but really...that headline is a little too optimistic at this point.  I really hope it does work and, I hope that the tests are done correctly and verified by others.  Then, we might really have something.
