Nuclear fusion milestone passed at US lab
BBC ^ | 7 October 2013 Last updated at 17:25 ET | By Paul Rincon Science Editor

Posted on 10/08/2013 6:23:05 AM PDT by Red Badger

Researchers at a US lab have passed a crucial milestone on the way to their ultimate goal of achieving self-sustaining nuclear fusion.

Harnessing fusion - the process that powers the Sun - could provide an unlimited and cheap source of energy.

But to be viable, fusion power plants would have to produce more energy than they consume, which has proven elusive.

Now, a breakthrough by scientists at the National Ignition Facility (NIF) could boost hopes of scaling up fusion.

NIF, based at Livermore in California, uses 192 beams from the world's most powerful laser to heat and compress a small pellet of hydrogen fuel to the point where nuclear fusion reactions take place.

The BBC understands that during an experiment in late September, the amount of energy released through the fusion reaction exceeded the amount of energy being absorbed by the fuel - the first time this had been achieved at any fusion facility in the world.

This is a step short of the lab's stated goal of "ignition", where nuclear fusion generates as much energy as the lasers supply. This is because known "inefficiencies" in different parts of the system mean not all the energy supplied through the laser is delivered to the fuel.

But the latest achievement has been described as the single most meaningful step for fusion in recent years, and demonstrates NIF is well on its way towards the coveted target of ignition and self-sustaining fusion.

For half a century, researchers have strived for controlled nuclear fusion and been disappointed. It was hoped that NIF would provide the breakthrough fusion research needed.

In 2009, NIF officials announced an aim to demonstrate nuclear fusion producing net energy by 30 September 2012. But unexpected technical problems ensured the deadline came and went;

192 laser beams are focused through holes in a target container called a hohlraum Inside the hohlraum is a tiny pellet containing an extremely cold, solid mixture of hydrogen isotopes Lasers strike the hohlraum's walls, which in turn radiate X-rays X-rays strip material from the outer shell of the fuel pellet, heating it up to millions of degrees If the compression of the fuel is high enough and uniform enough, nuclear fusion can result

Any day now millions of home cold fusion reactors will be rolling off secret factory lines. Within the next five to ten years for certain after the first five to ten years a possible design will perhaps be found to Change The WORLD!

The last time I checked in on progress in fusion technology, which was many years ago, the big goal was constraining a very hot plasma in order to extract energy from the fusion process.

This looks different.

Is it?

Harnessing fusion - the process that powers the Sun - could provide an unlimited and cheap source of energy.

Thus solving the energy crisis and leading us directly into the thermal crisis. If we really have nearly unlimited and relatively cheap energy we will start to heat up the planet. Time to get serious about getting off this rock. Oh, wait, that's right. NASA's primary focus is Muslim outreach or some such. Guess we're all going to fry while praying to Mecca...

If anyone is successful in accomplishing fusion energy, how long will it take for the Left to outlaw it? Probably about as long as it takes to measure the first fusion reaction.

Inertial confinement fusion, rather than "contained-plasma" (tokamak, Bussard Polywell, etc.). They're trying to do on a small scale what happens in a fusion bomb, only instead of triggering a fission bomb around a container of (insert your favorite fusion mix here) to get it compressed, they are focussing the energy of many, many, many laser beams onto a very small target that contains (insert your favorite fusion mix here).

The outer shell of the target explodes outward (and inward) under the impact of the lasers. The inward compression wave increases the temperature and pressure to above the fusion threshold. Fusion happens, and the innards of the small pellet now explode outwards, yielding excess energy.

NOT a practical route to routine energy production.

Much more likely to happen than this gizmo to become a practical power plant. LENR reached (and passed) "breakeven" years ago.

This is all propaganda.
This was already achieved in 1972 but taken over by the US. Air Force Black Curtain Project for military purposes, using common single-beamed split laser targeted mineral-based pellets with +++ n-results,

tested in battle with aircraft-platform delivered n-bombs in Serbia during Bosnian War to knock out tanks, keeping tanks intact undamaged but killing the crews.

a breakthrough by scientists at the National Ignition Facility (NIF) could boost hopes of scaling up fusion.

Hope is not a good strategy....even if it is spoken at budget time.

Keep in mind that, like fission, fusion isn’t something that produces electricity and you can stick an electrical plug into.

Fusion would be used to create the heat to boil the water that would be used to turn steam turbine/generator rigs used to produce electricity.

There wouldn’t be the radioactive byproducts created by fission, but it would require a lot of water snd there would be a heck of a lot of waste heat ejected into the atmosphere or into water (like the rivers/lakes/reservoirs the plants would gave to be located on)

THAT would form the basis for the enviros getting it banned.

Then look upon it as a jobs program. But for the over 55 out of work crowd retraining as a nuclear scientist is probably out of the question.

I haven’t seen anyone carrying a sign, “Will fuse for food”.

As long as you confine your attention span solely to Andrea Rossi, yes. But only a monomaniacal idiot would do that. LENR has many more practitioners than AR, and the scientific data produced by those practicioners provides the necessary proof. But then, you haven't bothered to look at any of THAT evidence, have you??

Oh, and I'm still waiting for you to tell me what "game" all those other scientists are playing.

My 1980 Master’s paper was on “Fusion by Laser Implosion”, based on research at Lawrence Livermore Lab.

Hope they keep quiet on any success over the next 3 years or this Energy hating administration will shut them down again.

I am not a physicist, I just play one on TV. Ok, I get that the energy released is greater than the energy input. However, the energy released, which I assume is heat, must be converted to electrical energy. To make electricity from heat a steam turbine is used. This type energy transfer mechanics is only 37% efficient. So unless the energy output is well over 3:1, fusion energy is still a long ways away.

The amount of energy needed to contain a fusion reaction must be derived from the reaction itself. That is the next step they have not engineered. The containment for reactions today require outside power and we cannot generate enough energy to contain a fusion reaction but for a brief moment.

Until a factory, an office, a house, an “out” house, a dog house is heated or has hot water provided by cold fusion it’s a lab experiment, a curious one and as I’ve said, It should be explored to find out what is really happening.

But save the attempts at petty personal insults, “Only to a “man of constant snarkiness” such as yourself.”, they fail.

"I don't follow it closely, but where is the best place to find factual reports on the progress of LENR research?"

Jed Rothwell's LENR-CARN.org website. If it has been published, and copyright allows it, it will be there, either in abstract or full paper.

He also reports "major news". Best unfiltered source is the vortex-l mail site.

"On another subject, what is the current news status of Rossi's antics?"

Not much on the science side. Latest is that he was visiting Sweden where one of his devices is either under test or about to begin a test.

If it’s a curious lab experiment — which has been replicated more than 14,720 times — that shows energy densities 50,000 times that of gasoline, how is it that you can say that “ the simplest use application is available”? By your reasoning, gasoline would not have “ the simplest use application is available.” You’re so anti-LENR that it fogs your vision when you look at the facts.
