The article is completely wrong about US Navy ships having fusion reactors. They have fission reactors, not fusion. I wonder if they are even reporting the breakthrough right since they clearly don't know the difference. For all we know the breakthrough may be smaller fission reactors too, which isn't a big deal at all.

> 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. sigh To the extent this is true I suspect those "large fusion reactors" are tuned not so much for generating electricity and a great deal for annihilating whatever the carrying missile is pointed at. But never mind fuzzy thinking at Reuters right now. This is amazing…

Here is more on the tech, including a drawing: http://aviationweek.com/technology/skunk-works-reveals-compa...

This article provides a lot more engineering information and other background and is well worth a thorough read. Thanks to flexie for finding and sharing the link.

I'm not sure why this article is focusing on things like whether the reactor can fit on a truck, where you get deuterium, and how many coal power plants it can replace - instead of the actual question which is how they managed to produce a stable exothermal fusion reaction.

nevermind, this is hype - buried in the article

The team acknowledges that the project is in its earliest stages, and many key challenges remain before a viable prototype can be built

This falls under the xkcd 10 year plan:

"we haven't finished inventing it yet, but when we do, it'll be awesome"

Very cheap energy means cheap war and lots of it. This could be bad.

If they can manage to build what they envision we will have tanks with with laser weapons.

On a similar vein, I wonder what are the strategical consequences of such an advance. Assuming it works as described in the article, do you allow the technology to be exported ?

Because a whole fleet of fusion air carriers, battleships, submarines and bombers versus a conventional army has plenty of implications in term of autonomy, reach, etc.

But on the other hand, there is a such demand for energy everywhere that it would really hard to morally ban all the civilians applications.

Our main reason for war right now is scarce energy.

Cheap clean electricity means no-one needs to care about the Middle East for starters — most of the fighting there is superpower proxy fighting — e.g. Assad would be gone if not backed by Russia and China, so no Islamic State. No Oil, no Iraq war x2. No oil, no Hugo Chavez for that matter.
