A student of mine submitted this story for his weekly science article. Let's just say that I am interested.

Shouldn't find it at all surprising that Skunk Works may usher in yet another major shift in technology (U2, SR71, B2).

If (when?) they succeed, I cant imagine how much this will change the world as we know it.

I would imagine those cost/ease of production will be important but if there's no radiation to worry about, I have a feeling they will be cheaper to make than the Nuclear reactors we have now.
It may even be one of those things like they said in the 50's where eventually people could have water-heater sized powerplants in their garage someday....



with 3-D printers who knows?

To paraphrase what the person said in the comment section of the SA article, "Fusion power is 10 years away, it always has been and always will be".

The super-safe small modular fission reactors mentioned in the comment section also seem to to have been just a few years in the future for a long time also. The Popular Science articles about future power sources always sound so convincing, but somehow they can never really get a commercial one built.

I sure hope I am proved wrong in the next few years.

I don't know if it would change the world, but holy cow, it would be a really REALLY good thing.

Virtually limitless fuel.
No chain reaction, no "meltdowns".
Very little of that pesky nuclear waste.

I read a LOT about this today and I'm pretty skeptical about this news. I really hope they have stumbled upon a break through. I mean billions upon BILLIONS have been spent in the past decades trying to sustain a usable fusion reaction.

Generating useable electricity from a fusion powerplant has been around for a long while.

Yabbut how much energy was put in versus how much was put out?

Got a link?

Thermonuclear bombs? Or do you mean photovoltaic cells?

Before I get my panties in a wad over what the journalists report, I kind of want peer reviewed details about what this "technological breakthrough" is. Otherwise all I see is:

"Lockheed Martin Corp said on Wednesday it had made a technological breakthrough in an erroneous sensor reading while developing a power source based on nuclear fusion"

And then I notice they say "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."

Orly?

Meh. Even if it becomes feasible, I have a sneaking suspicion that the huge energy corporations by of of backdoor government deals will have a chokehold on the systems. Hell maybe they already do, waiting for the oil to run out before they go "oh haaaayyyy guyyys, look what WE figured out, just in time for the runout of oil! We are your saviours! Give us more money!"

Does anyone have an article how they plan to take this energy from laser based fusion and turn it into electricity? Some sort of jacket around the metal to absorb it and then make steam/run conventional turbines? Or something more exotic?

That's kind of funny that this just popped up on my newsfeed.

Scientists Are Bashing Lockheed Martin's Nuclear Fusion 'Breakthrough'


Quote:
Although Lockheed Martin issued a press release saying it had several pending patents for its approach, the company has yet to publish any scientific papers on this latest work.
