Both NASA and institutes in China, and Germany having been researching this engine, so its not like this crack pot science.
What do you think ATS? Sounds great to me.
In physics, a virtual particle is an explanatory conceptual entity that is found in mathematical calculations about quantum field theory. It refers to mathematical terms that have some appearance of representing particles inside a subatomic process such as a collision. Virtual particles, however, do not appear directly amongst the observable and detectable input and output quantities of those calculations, which refer only to actual, as distinct from virtual, particles. Virtual particle terms represent "particles" that are said to be 'off mass shell'. For example, they can progress backwards in time, can have apparent mass very different from their regular particle namesake's[dubious – discuss], and can travel faster than light. That is to say, when looked at individually, they appear to be able to violate basic laws of physics.

I didn't really see this in the technology area so I thought I would post it.
I've read about this thruster design in the past, and recent test earlier in the year suggested they wanted to verify results in a vacuum chamber to rule out other causes, but now it looks like even those test are leaving scientists to lean more towards this being the real deal. You can read about the engine HERE on wiki, or just google it up for yourself.
Here is an image from JSC Eagleworks showing the field surface distribution.
The main argument to the premise of this engine, is that initially it was thought to violate the law of conservation of motion. According to its creator Roger Shawyer though, who invented the EM Drive in the early 2000s, says: "To put it simply, electricity converts into microwaves within the cavity that push against the inside of the device, causing the thruster to accelerate in the opposite direction,". Long story short, he basically he thinks it's supported by the Lorentz force - F = q(E + νB).
And according to the Eagleworks vacuum tests it, it actually looks like that may be really be whats happening (but not confirmed yet). NASASpaceflight.com has really tried hard to debunk this, but so far, they haven't.
So now where talking about earth to mars transits of 90 days (for the record, a 1-2 megawatt power source is needed...hard but not impossible to get into space...but just to be devils advocate....).
Guess what? There is icing on this cake....
Reported on NASASpaceflights forum HERE it has been reported that lasers fired (taking measurements i'm assuming) into the resonant chamber that the laser light exceeded the speed of normal light at 300,000 kps...the "theory" is that inside the cavity a bubble of space time is getting warped (causing the appearance of faster than light...er light).
Well..to me this is just incredible. It wouldn't surprise me if the warping theory turns into something that isn't warping at all, but what an extra bonus to an already cool finding on the latest research.

One of the top engineers working on NASA’s controversial EM Drive thruster at the Eagleworks Laboratory at the Johnson Space Center in Texas has spoken publicly about the current state of the project. This is the first direct update in months, as NASA is keeping a very tight lid on the developments.
The latest news regarding the EM Drive, which produces a thrust seemingly from nowhere, comes from Paul March, one of the principal investigators on the EM Drive, and was published on the NASA Spaceflight forum. The post is in reply to an unpublished paper that claims the unaccounted thrust is generated by the Lorentz force between the EM Drive and the Earth’s magnetic field, something that March says his tests prove is not true.
“I will tell you that we first built and installed a 2nd generation, closed face magnetic damper that reduced the stray magnetic fields in the vacuum chamber by at least an order of magnitude and any Lorentz force interactions it could produce,” commented March in the post on October 28. “And yet the anomalous thrust signals remain...” he added.
March also claims that in the latest developments, thermal expansion of the thruster is taken into account to reduce all possible sources of error. But the anomalous thrust is still being observed, indicating a yet unexplained cause for it.

Does this mean that if we all turn our microwaves to power level 10, open the doors and turn them on all on at once, then we can move the Earth?
But really, that this hasn't been debunked (yet) is weird and neat... about time. It's usually anomalies, after all, that open up whole new vistas of knowledge.
The microwaves, behaving as particles , transfer energy to the cone, I'm not seeing how this is a violation of the laws conservation of momentum.

I wouldn't be so excited just yet. No matter how you slice or dice it, this machine violates momentum conservation. Much of fundamental physics known today is built on this principle, and if this machine works, practically all of it would have to be reworked. Not only that, but it would have huge consequences in the way we think about space and the homogeneity of space which follows from momentum conservation.
An FTL device would be a lot easier to incorporate and accept in mainstream physics (would violate only the WEC in GR) than this machine that breaks conservation of momentum. Right now, it's a lot more likely that these people are crackpots who don't know what they are doing than one of the cornerstone principles of physics being found to be violated surprisingly in attempts at building better propulsion systems but was missed at all the accelerators around the world where such violations of conservation laws would easily have shown up by now.

Think a bit harder. Where do the microwaves get their momentum from?
