I guess that's somewhat game-changing. This, however, would be much more game-changing (if we can get confirmation once and for all whether it's real or not): http://www.extremetech.com/extreme/191754-cold-fusion-reacto...

Earlier quoted context omitted.

From what I've heard, the reactor actually outlives the ship, no?

I know there are some very smart people at skunk works who've done incredible things in the past but humans have cried wolf so many times on fusion it's sort of hard to just accept until they've actually built a working reactor, shown it and had it independently verified.

Fusion physicists I know are very sceptical that this design can work. It's a variant on a known design with a known problem: the plasma leaks out of the ends of the magnetic containment. It's also unclear why Lockheed would be publicising it this way at this point, unless it's a naked ploy for more funding from the DoD, and an attempt to bring in money (and possibly pressure) from non-classified sources.

That being said, if they've genuinely cracked it, the game changes so much as to be unrecognisable.

We have working reactors they just don't output more energy than they consume.

We should be throwing more money at this...

I don't know much about fusion. It seems that the breakthrough they're talking about is that reactors are ~10x smaller. Why is this a big deal? Square footage is plentiful. I thought the problems are safety and how much energy it could produce.

If it's 10x smaller it is available for portable applications. Like boats/planes/space ships. It would also presumably be easier to air drop in developing regions to bypass building a giant energy grid (similar to cell phone deployment).

>U.S. submarines and aircraft carriers run on nuclear power, but they have large fusion reactors on board that have to be replaced on a regular cycle. I don't think so.

This bothers me immensely. Clearly, neither the author nor the editor for a "Scientific American" article (for pete's sake, science is in the name!) know the difference between nuclear fission and nuclear fusion.

This article is the cognitive equivalent of parrots squawking, because they don't even understand why the news actually is news.

People calling this a "typo" are giving too much credit. It could be a mistake, but the whole point of having an editor is to catch typos and mistakes! And it's a simple, short article!

> could be ready for use in a decade. That's the standard issue joke. "Nuclear fusion has been just ten years away for the last fifty years" It is so common as a joke I'm surprised the article didn't mention it.

What's different this time (yeah, I know, I know) is that, if what they and EMC2 are separately claiming is true, it's gone from being a fundamental physics problem to relatively tractable engineering, with well-understood risks and timelines.

Compare this with ITER, where they still don't know what material some fairly critical components can even be theoretically made of. It's just night and day.

Then the dilemma becomes: Does the USA share this with other countries? Or do we keep our clean, plentiful power for ourselves, become energy independent, have clean skies, and keep (exploit?) this technological advantage over the rest of the developed world for the next 20-30 years?
