Don't Get Too Excited About NASA's New Miracle Engine, io9
"Earlier this week, Wired reported on an unusual engine designed and tested by researchers at NASA's Johnson Space Center. Dubbed the "Cannae drive," the propulsion system is similar to the so-called EmDrive, a "reactionless" engine proposed years ago by british engineer Roger Shawyer and popularized in a 2006 writeup in New Scientist. Both space drives are designed to convert electric power into thrust by bouncing microwaves around in a closed container, thereby eliminating the need for onboard propellant. The concept has beenroundly criticized for appearing to violate the law of conservation of momentum."
NASA: New "impossible" engine works, could change space travel forever, Gizmodo
"Now, American scientist Guido Fetta and a team at NASA Eagleworks--the advanced propulsion skunkworks led by Dr Harold "Sonny" White at the Johnson Space Center--have published a new paper that demonstrates that a similar engine working on the same principles does indeed produce thrust. Their model, however, produces much less thrust--just 30 to 50 micronewtons. But it works, which is amazing on its own. They haven't explained why their engine works, but it does work."

"This paper describes the eight-day August 2013 test campaign designed to investigate and demonstrate viability of using classical magnetoplasmadynamics to obtain a propulsive momentum transfer via the quantum vacuum virtual plasma. This paper will not address the physics of the quantum vacuum plasma thruster, but instead will describe the test integration, test operations, and the results obtained from the test campaign."
Nasa validates 'impossible' space drive, Wired UK
"Nasa is a major player in space science, so when a team from the agency this week presents evidence that "impossible" microwave thrusters seem to work, something strange is definitely going on. Either the results are completely wrong, or Nasa has confirmed a major breakthrough in space propulsion."
Improbable Thruster Seems to Work by Violating Known Laws of Physics, PBS
"In the paper, NASA seemed reluctant to dive into the drive's mysterious physics. They wrote nothing to suggest how, exactly, the force was produced. In fact, the mysterious drive actually worked even when they modified it in such a way it shouldn't have produced any thrust, suggesting the mechanics of the system are hazily understood. The one exception was a reference, in the paper's abstract, to a possible interaction with the "quantum vacuum virtual plasma."
Keith's note: JSC sure has some far out stuff under development. You'd think that they'd want to talk about it. But they don't. You'd think that they'd feel some compulsion to tell taxpayers what their money is being spent on - especially if it is cool. Guess again.
Could it be that this thing does not actually work - and NASA is afraid to admit that it doesn't work? This is a much more plausible explanation.
I asked some questions about all of this exotic propulsion stuff going on behind closed doors at JSC last year and got this semi-responsive reply back. The researcher behind all of this secret stuff is Harold G. White. According to people.nasa.gov here is how you contact him: email: email@example.com Phone: 281.482.0178. Every time this guy's research pops up in the news JSC PAO hides under their desks.
