Perhaps...
After over a decade of skepticism, a newly released NASA paper seems to show that it works. They don't say why it works, and it only works a little bit, but even if it's only a little bit, then it breaks some accepted laws of physics, and opens some doors to future long range and duration space propulsion systems.

The abstract states that a modified version which should not have worked - also works. Third paragraph:

"Thrust was observed on both test articles, even though one of the test articles was designed with the expectation that it would not produce thrust. Specifically, one test article contained internal physical modifications that were designed to produce thrust, while the other did not (with the latter being referred to as the “null” test article)"

I'm not sure what to make of this.

Edit: Full paper for those with Uni access: http://arc.aiaa.org/doi/abs/10.2514/6.2014-4029.

Yes - that's a serious problem.
