Nice topic.
We pump electromagnetic waves (momentum is given by p=h/lambda=h'k) into a resonator and by the asymmetric design of the resonator the reflection and losses are not the same at both ends of it? --> k of the wave changes with resonator diameter (I looked up the equations for propagation in waveguides)
So we have a higher p=h'k at the bigger side of the tube?
Either I am an amateur or the science journalists have no clue what they are writing.
I hope I can witness the first spacecraft in 20-50 years to utilize this technology

Can't trust journalists these days to really figure out anything.

This is one of the most exciting technologies that i've read about. For starters, its inventor has been mocked and derided by the physics establishment. The Chinese thankfully are more interested in science than upholding a dogmatic view of science.

I hope its inventor is vindicated with a free flight to space. I find the current class of most scientists these days to be as bad as the catholic church was back in the days before the enlightenment.

Anything to get us off of this rock and into our solar system is a good thing. Humans needs constant growth and since there isn't anything new here on this planet, we need a new frontier to conquer.

The EmDrive peer review paper has been leaked and is out in the public domain.

Quote:

The paper was leaked onto the Nasa Spaceflight enthusiast forum on Saturday 5 November by an Australian EmDrive fan called Phil Wilson, who goes by the username "The Traveller". Nasa Spaceflight's moderators decided to delete the post, since the paper has not yet been released, as did Reddit's moderators. It is slated to be published by the American Institute of Aeronautics and Astronautics (AIAA) in December.

Nasa Spaceflight's moderators decided to delete the post, since the paper has not yet been released, as did Reddit's moderators. It is slated to be published by the American Institute of Aeronautics and Astronautics (AIAA) in December.

However, science-tech news site Next Big Future has decided to link to the paper and upload diagrams from it, thus ensuring that the content is now, irrevocably, in the public domain.

IBTimes UK was given access to this early draft of the paper and an accompanying video of an EmDrive experiment in October, but we made the decision not to interfere with the scientific peer review process, as it goes against journalism best practice.

The paper is exciting to EmDrive fans as it indicates Nasa has succeeded in replicating the work British engineer/scientist Roger Shawyer did in 2006 to produce rotating thrusters and prove the controversial device does in fact obey Newton's Laws of Motion.

Nasa Eagleworks researchers detail in the paper that, using light sales and microwave photon propulsion, they were able to produce 3.33-6.67 micronewtons per kilowatt in thrust, which is two orders of magnitude less than Shawyer's 2006 results.

IBTimes UK published a video of Shawyer's experiment back in 2014, which simulates a 100kg spacecraft on an air bearing being moved counter-clockwise by a microwave thruster. Above is the video of the same experiment, replicated in Nasa Eagleworks' laboratory in 2015.

In the experiment, Nasa's thruster achieved 270 degrees of rotation under power, over 32 minutes, before the battery ran out and then allowed the turntable to rotate 12 turns over a further 89 minutes.

"[It's] all very slow but very convincing. There's some very serious work going on and I expect to see a lot of exciting stuff about the EmDrive in the news in the near future," Shawyer told IBTimes UK.

"It's a nice bit of publicity but really it's nothing new. But for the people who are really sceptical about it, seeing something move is the most important thing. When Galileo was put on trial by the Catholic Church in 1633, he reportedly said of the Earth moving around the Sun, 'Even so, it does move.'"

The Nasa Eagleworks paper does seem to prove that the EmDrive works, however enthusiasts on the Nasa Spaceflight forum feel that the leaked paper is very likely not the same as the one that AIAA will publish, and in fact relates to research dating back to 2014 and 2015, much of which is already known to enthusiasts.

For his part, Wilson says that he chose to release the data onto the Nasa Spaceflight forum because he didn't believe AIAA intends to actually publish the paper.

He is concerned that Nasa could in fact soon decide to close down the Eagleworks Laboratory, which is considered to be a sort of "moonshot" experimental laboratory for investigating fringe theories in advanced propulsion physics.

"All this work was funded by the US taxpayer and conducted by a US government nonmilitary establishment, so nothing done by Eagleworks was classified," he told IBTimes UK.

"Despite that, very significant EmDrive research has not seen the light of day and many around the world make incorrect assumption about the non-functionality of the EmDrive and the work that EW achieved.

"I need to ensure this information sees the light of day and is not held back from the public."

This is the sort of shit Elon Musk needs to get his ass into, not self-driving cars.

That EM drive works because it's not part of a closed system as the author explains here:

The topic of anti-gravity and electro-gravity propulsion is fascinating to me (who wouldn't find it so!), and is of national and world-wide importance. However having dived into that rabbit hole a bit and encountered various characters it seems there's an entire industry devoted to keeping discovery and actual devices from the everyday citizen.

Many brilliant investigators in this field have met untimely ends. I've watched several videos that have made it clear the science is sound, if not what's taught in schools (hmm I wonder why, like how we know 9/11 was not a bunch of terrorists flying planes into buildings).

What non-scientists or paid-establishment shills decry when hearing about 'free energy devices' is an unfortunate attempt to discuss an ancient and vitally important area of study. The gov't frowns upon open experimentation (if not blocking or confiscating work as with Thomas Townsend Brown in the 1930s). I do believe we are opening up a new renaissance with the widespread use of the internet to disseminate information but not sure even DT can do much in this realm. He'll have his own secret briefings when the time comes but the black op gov't projects are not known to standing presidents.

If / when someone can offer a DIY gravity drive then we've got something. We can't rely even on Musk (who even though he's a visioneer I regard with some suspicion).

Fairly technical but illustrates the science already being done in this area and important conceptual findings. I've ordered several books from the speaker:

The first time a group of people can actually coordinate and meet in secret to build a working anti-gravity craft will be the modern equivalent of the Wright Brothers achieving powered, manned flight. The less public the project, the better off we are.
