So the E-M drive is real? And they even have evidence for faster than light transmission? Paging Bill Higgins. ..

Seems like there are still a lot of important questions to be answered, like how does it work, but wouldn't it be amazingly cool if it did?

Most of that article is devoted to "wouldn't it be amazingly cool if it did?" Mars joyrides, warp drives, et cetera. If one is trying to establish some fundamental physics, it's a little early to start talking about the speed of one's Mars ship and what color it will be painted.

I'm not keeping up on this affair (there was an Internet fuss over it last summer), so don't mistake me for someone who has thorougly studied the science here, but color me very, very skeptical. Also, if they ever publish their results in Physical Review Letters rather than Some Internet Forum, let me know. That might be a signal that we should start paying attention.

A friend compared it to cold fusion, and I can't disagree. I've been told that the NASA paper this article is based on is three years old and that nothing else has been published since then, which makes it even more suspect. Still, I am reluctant to give up hope since it would be a great leap in propulsion if it proved out. We really need something like that to make space travel practical.

Katie M. Palmer at Wired has a pretty good rundown on the EM Drive situation, although as often happens, the headline ("That NASA Warp Drive? Yeah, It’s Still Poppycock") is less even-handed than the story itself.

She gets quotes from the people I would have talked to, were I in her shoes, Marc Millis and Eric Davis.

Update says results are about to be confirmed by Germsn scientists. While quotes like
Quote:
virtual particles in the quantum vacuum that behave like propellant ions in magneto-hydrodynamical propulsion systems, extracting "fuel" from the very fabric of space-time
set off my pseudo-science radar, apparently some credible people are taking this seriously.

No FTL though, but still, what's left is damn impressive. I may sprain something crossing my fingers...
