New hope for ultimate clean energy: fusion power
April 12, 2010 By Bob Beale(PhysOrg.com) -- Imagine if you could generate electricity using nuclear power that emitted no radioactivity: it would be the answer to the world's dream of finding a clean, sustainable energy source.
That is the great hope raised by researchers who believe they have found a radical new path to the ultimate goal of solving the world's energy crisis through nuclear fusion power, as detailed in a paper published in the journal Energy and Environmental Science.
The international team of researchers - led by Emeritus Professor Heinrich Hora, of the University of New South Wales Department of Theoretical Physics -has shown through computational studies that a special fuel ignited by brief but powerful pulses of energy from new high-energy lasers may be the key to a success that has long eluded physicists.
The intense laser beam would be used to ignite a fuel made of light hydrogen and boron-11. The resulting ignition would be largely free of radioactive emissions and would release more than enough energy to generate electricity.
The amount of radiation released would be even less than that emitted by current power stations that burn coal, which contains trace amounts of uranium. In another plus, the fuel source is plentiful and readily accessible and the waste product of ignition would be clean helium gas.
"This has the potential to be the best route to fusion energy," says Steve Haan, an expert in nuclear fusion at Lawrence Livermore National Laboratory in California, in a news report in the Royal Chemical Society's Highlights in Chemical Technology.
Both Haan and Hora caution that the study only demonstrates the potential of the new process and that much work would need to be done to demonstrate it in practice.
The conventional fusion process uses highly compressed spheres of deuterium and tritium as fuel. Hora says the proposed new process overcomes previous objections to hydrogen-boron11 fuel because it would not have to be compressed and therefore need much less energy than previously thought to start the ignition.
"It was a surprise when we used hydrogen-boron instead of deuterium-tritium," says Hora. "It was not 100,000 times more difficult to ignite, as it would be under the usual compression process. It would be only 10 times more difficult, using the latest generation of lasers."
As it happens, a unique new laser capable of producing the required amount of ignition energy is in its early stages of testing in the US at the Los Alamos National Laboratory.
Another extraordinarily powerful US laser known as the National Ignition Facility has been built at Lawrence Livermore National Laboratory: "It is the largest laser on earth and has cost about US$ 4 billion," he says. "The laser pulse of about few billionths of a second duration produces 500 times more power than all US power stations."
Professor Hora, who founded the UNSW Department of Theoretical Physics in 1975 and has been an Emeritus Professor since 1992, is known for his work on the theory of fusion energy with lasers.

The ICEs of the past was a lot more robust and could run on different fuels, but as far as I'm aware, today's engines are a bit more picky as they're specifically designed for the fuel they're supposed to run on.

There is no "Peak Oil"- a marketing scam to drive up price.
Gasoline engines are the driving force behind oil price fluctuations. Eliminate the gasoline-powered engine through phase-out, and phase in alternatively derived fuels/electricity/fusion/inertial storage- whatever.
Why do we insist on relying upon a manifestly harmful, poisonous, polluting fuel????
It's all about profit!!!! The entire global economy, the health of our environment, and our individual quality of life will continue to be dictated by the fossil-fuel industry until we decide -individually and collectively- to find a way to employ these new technologies and processes to entirely supplant the fossil-fuel economy.
Take your money out of Petro-based investments, and put it in alt-energy start-ups like Bloom, Siemens, et al(there are plenty). That money's not going to do you or anyone else any good, if you live in a wasteland, fighting over some scraps of food and a few mouthfuls of dirty water.

But Peak Oil is no myth my friend. There was only so much bioslime that died during the anoxic conditions and abiogenic production hasn't been replicated. Kerogen is always appearing to be a biotic waste product more and more each day, and with no Kerogen, and a lack of geological time and heat, we'll certainly run out.

The idealistic left want to fix everything now, without having any alternatives in place that could even come close to substituting oil/coal.

It's not recommended to just throw B100 or E100 into a desiel or gas powered car as they are now. Modifications can be made to the vehicles to make them run better for B100 and E100, but that goes back to my original point that it would be difficult to get everyone to retune all the cars on the road to run on alternative fuel sources. Even "flex-fuel" cars (which are fairly new) are only designed to go up to about 85% ethanol.

You *can* run a car on pure ethanol, but it requires the car to be re-tuned for the correct fuel-air mix. Probably requires a different set of additives to maintain the octane number (not that that's a huge problem, seeing as though they already have high ethanol fuels available).
The big problem is in the production and refining. You can't just switch the whole industry to another fuel source overnight - the supply just wouldn't be there. And bioethanol production is still expensive; a lot of our ethanol just comes from petrol ANYWYAY.

Absolutely wrong. To force a "solution" is to break from existing free market, and would require social engineering (leftist button pushing), to moderate use. This is a fundamental change in the form or role of government. Alternatives must COMPETE with oil and win it's share of the market naturally, otherwise it's socialism, period.

Since it's an annual crop and can grow on marginal land quite well (hell, kids grow it in their basements in old PC cases under CFLs), and it is an annual crop, it's a sure fire winner.

As far as the debate over oil and fossil fuels go, I can tell you that the deck is stacked for the fossil fuel companies. They get huge tax breaks on exploration. People here are using words like "freedom" to describe using fossil fuels. Of course, we're borrowing money from China to finance oil exploration. If we cut all tax breaks for the oil companies, you'll see just how expensive that stuff is (hint, about twice as much).

b. Actually that's probably what it is. And a heads up to citizens to expect their next vehicle to be green... peak oil can be artificially created. Oil is valuable for many things besides combustion. We should expect to be using it long after we stop burning it. Crises can be a way of forcing conversion from one tech to another. By the time the price comes down again we'll be running fusion plants and driving electric cars and won't need petrol any more.
Besides, irans army hasn't had a war for too long. Unless it is used (up) soon it will become a problem. This is why saddam invaded Kuwait; so he said.

OK, forget about naive, how about provably wrong. Sooooo much technological innovation comes from Government ... for example, the internet. It's way worse (for you than that). In a totally free market, the internet NEVER gets created. It's because of local minimums -- there is no investment move by a private entity that makes an internet pay off. It's only when the internet is already proven and created that a google can arise. Same is true for all fundamental research -- it's simply a waste of money to do it, because you, privately, will not benefit from the advance ... your neighbor who didn't waste all his capital researching will.

More seriously: If compression fusion requires such profligate amounts of energy and design to kick start it, how can it happen in star formation when there's nothing but thinly dispersed gas clouds without any outside help? Surely Not? Doesn't the compression of a gas heat it up and then the pressure resists any more compression? And we know from fusion reactors that close to critical temperature the magnetic fields just go absolutely haywire - to the extend that plasma just leaps out at random? So just HOW can stars form in the vacuum of space where there are no constraints? Seems impossible to me.
