Giant International Fusion Reactor Draws Nearer
nnnneedles writes "BBC is reporting that scientists are deciding on where to build the world's first big fusion reactor. The international effort is described as the boldest nuclear initiative since the Manhattan Project, and holds promise for future unlimited, clean energy. The choice on where to build the reactor currently stands between Japan and France, but apparantly, the U.S. is opposing a french site because France opposed the war in Iraq." There's also an AP story.
is eating at French restaurants in DC these days.
Time to move on.
Last time I checked, Canada, Russia and China preferred the Japanese site. And I seem to recall they all opposed the Iraq War.
The site selection has nothing to do with anyone's position on Iraq or else France would have the support of the other countries as well. As it stands, they only have the support of the EU for typical reasons.
-- You see, there would be these conclusions that you could jump to
Fabulous concept, but we've been 20+ years from having fusion power for about 50 years now... Of course, "we can do it in 20 years" is bureaucrat speak for "we don't have a clue, but why don't you give us some money anyway...."
Not to sound like an ass or something but this seems like a really childish behaviour.
--- No, english is not my mother tongue.
What, with their obvious tectonic stability, vast distance from any faults and subduction zones, and lack of volcanic activity, they are the perfect choice for building a big, expensive, multinational fusion reactor.
Personally, my preferred choice would be Canada, somewhere on the Canadian Shield.

which uses enormous power hungry electromagnets to compress hydrogen to the point at which it fuses. Unfortunately, this means that even if it is actually capable of producing more power than it consumes (like they claim on the web site) it will be monumentally inefficient compared to more modern fusion reactor designs, like the zMachine
It's not because they are peace-loving (France doesn't exactly qualify, historically), and it doesn't even have much to do with them not supporting the war in Iraq, though that made a good litmus test.
Basically, the current US administration wants to hurt, as badly as is conveniently possible, and as often as is conveniently possible, any county that does not cooperate fully with the whims of the US government. Regardless of the convictions and ideals of the populace or the government.
So, since France's people overwhelmingly did not want to be a party to the war in Iraq, and because France's government actually listened to its people, instead of listening primarily to the US and only secondarily to its people, it is clear that France is not sufficiently in thrall to the US, and therefor must be punished.
Iraq was just a test. France failed.
Or passed, depending on your viewpoint.

Sign #11 of Slashdot overdose: You see the phrase 'moderate Republican' and you wonder if that would be a +1 or a -1.
Ive seen this one... Japan gets it. They gain ulimited energy, use it to fuel their great cities, only to have their robotic servants rise up and enslave them, all the while unleashing a great evil upon the world, that only a perky, well-drawn, female scientist and a guy with pointy hair can stop... meanwhile the villain is secretly planning to use the mega energy device as a weapon to destroy the world... Then Godzilla comes from the Island of Monsters and smushes everything... and we turn them away thanks to the loveable japanese children who sing to Gamera and those two twins that dance for Mothra... and umm... um... and just when Ultron's energy is about to give up, Skippy says, "Ultron I believe in you!" Then half the characters die in a horrible holocaust, while one or two tokens who might've drawn close together to each other in the conflict end up going away to pursue profitable careers in archeaology...

I worked at the General Atomic D3D facility in San Diego, the 1980s. The biggest limitation on the rate at which they could explore the experimental parameter space was the number of neutrons that the machine would create. The ultimate end of all modern tokamaks is to be turned into low-level radioactive waste when the machine itself becomes activated by the free neutrons liberated by the fusion process.
The more conventional gamma rays, alpha radiation (helium nucleii), and beta rays (fast moving electrons) are dangerous enough but at least they aren't infectious: you can irradiate food with gamma rays and it doesn't turn radioactive. Neutrons get absorbed by nearby nuclei, which then themselves become unstable and radioactive. Ick.
That's not to say we shouldn't explore nuclear fusion as a power source -- just that it is not the perfectly clean energy source that it is often made out to be.
Who in the US administration actually stated that the US opposed a French site because of their opposition to the war in Iraq? What does this have to do with Iraq!? Wouldn't France be the obvious choice? The French have the most experience, e.g. keeping a whole country full of fission reactors humming along.

You might have a point, if this reactor were intended to SUPPLY energy for a large area.
It's not. This is apparently an experimental reactor. We haven't made this work yet; this reactor is being built so we CAN make it work through experimentation. After that, I would imagine all the countries will simply build their own reactors to supply their countries (and neighbors who wish to purchase energy and/or share in the construction costs) with energy.
What did you think, we'd build one reactor and supply the whole world with energy? Please. At the very least each country will want their own simply so their energy source simple to guarantee the existance of their own energy in case of war or natural disaster.
If this technology WORKED, you think the US in particular wouldn't drop $10bil on it in a heartbeat to build it ourselves? It doesn't work yet, and that's why we all want to build this experimental reactor.
Why is that relevant? What are they going to do, recharge their battery powered Humvees?

How do you reach that conclusion exactly? Other than not supporting a war without a second resolution I haven't noticed the French supporting much terrorism. You never hear people in Camp X-Ray breaking down and saying "okay, I give in. M. Chirac made me do it."
France does have a large muslim population due to its old (fairly disastrous) colonial association with Algeria but, as many people have pointed out, muslim != terrorist. I'm sure France is making every effort to root out any terrorists that may be hiding there.
There is far more evidence for active terrorist cells in Frankfurt, Hamburg and Birmingham than France. That doesn't make Germany an untrustworthy country, either.

Can you back up the accusation that France harbors support for terrorism?
Also, can you consider that there is no "need" to adapt fusion power to weapons, it is called the H-bomb and I'm pretty sure France already has them.
excuse me but why is this modded +5 informative? The Z-machine is no more modern than 10 years more modern than the tokamak and it sure as hell isn't efficient (in terms of fusion production) by any means. It's barely producing a million neutrons in its implosions; billions of times less than the energy input into the implosion.

The most viable known methods of generating and sustaining fusion both use and generate radioactive material.
The best fuel for igniting fusion is a tritium/deuterium mix because it fuses at a lower temperature. Tritium is a radioactive form of hydrogen with 2 additional neutrons. It is "bred" from lithium, but it's still a very radioactive substance. Technically speaking, fusion reactions do use radioactive material as fuel. DD reactions are possible, but they require higher temperatures and are less likely to be viable.
Secondly, the DT reaction emits neutrons. It's a simple matter of math - you have a deuterium and tritium nucleus which collide and produce helium. There's a neutron left over, with high amount energy and no electric charge. It will "ping" right out of the magnetically confined plasma. Most such neutrons will be absorbed by the lithium shielding (creating more tritium) but some will fuse with other parts of the reactor, creating, you guessed it, radioactive waste.
Commercially viable fusion reactors, if they ever exist, will almost certainly produce radioactive byproducts. It will be a great improvement on fission power, as there will be less waste in total with a shorter half-life, but radioactive waste is radioactive waste. Like fission waste, fusion waste will be expensive to deal with and be around for many generations.

Not that's I'd expect Slashdot (or the BBC) to get the whole story. As much as I like Slashdot this place is definitely ultra liberal and has an agenda to go with that... so always helps to verify anything you hear on this first before you believe it. (As everyone should on ALL media sources before they go spouting it as fact)
We'll basically be like the Tlulaxu and Ixians, but without all the shape-shifting. All I need is money to buy the island and a tech base. Who's with me? I'll set us up a paypal account.
I am so sick of the how the stories that get posted on Slashdot always have some wording to get this site going on a political bent. This story could have stimulated some interesting technical discussion - but because it had a tag line that mentioned the French / American thing, it will degrade into yet another Slashdot American / European / Asian / etc. bashing....
Please PLEASE keep it about "News for Nerds" and "Stuff that Matters"
The article asserts that the US is opposing the France option because of the Iraq war.
Just because some reporter makes this claim doesn't make it true. What is the source of this? There is nothing in the article to back it up. Maybe the claim comes from a source that is simply guessing as to the US's motives. Maybe the source is trying to divert attention from legitimate objections by claiming this is all politically motivated. We don't know.
Take this article with a grain of salt.
The AP story doesn't prominently mention the us objection to France because of their object to the war in Iraq. Conversly, the BBC story makes ABSOLUTELY NO MENTION of what the "us objections" actually are. I have not been able to find any credible mention of who and what the actual objections are. Is this just a quote from someone with an axe to grind?
The technical aspects of this are much more interesting than the political ones.
Technology will always devolve to the least common denominator. Polictics will always devolve to the marginalized just bitching.
If at first you don't succeed, redefine 'success'
Yes, the "fusion power will be workable in N years" mantra that's been heard from many sources for the past 40 years is frustrating, and considering that here it is 2003 and we still havent even reached ignition in any laboratory reactor is dissapointing to say the least. However, it is important to note that during this time fusion research hase come a VERY long way. I don't see how this progress can continue forever with no results.
- "Hear that?! The percolations are imminent! Cease your ingress!"
Excuse me but what statistics have you read? The war was probably about a 50/50 split in the US. Where did this slim minority BS come from?
Ok, so where are your stats.
Yes the many other Islamic countries were against the war. Islam has taken over 100 countries in the world now. If they feel threatened by anyone dealing with another Islamic country, then that's life.
There are a few interesting things I'd like to point out here. First, your use of 'taken over' in reference to Islam. How many countries has Christianity 'taken over'? Why do you think the country has been captured by a religion? And which hundred countries do you suppose this has happened to? I bet you can't name a dozen.
As far as France, Russia and Germany, yes they also didn't want the war. They were supplying Saddam and were owed billions. They still are. People forget that France was making the planes that Iraq used to gas its own people. That is why there was so much pressure against it. Those countries stood to lose money they were owed if the US invaded. You people are so easily swayed by propaganda instead of looking at facts that you really piss me off.
Ah, yes. It pisses me off too, which is why I'm replying to your bad information.
France, Russia, China, the USA, and Germany have all provided military equipment to Iraq. The USA has additionally outfitted Iran and several neighbours. The Russians, Germans, and French are owed money largely for infrastructure, electrical generators, sanitation equipment, and the like. But get this straight - no one is innocent in this, and the USA is certainly, far and away, the worst offender.
The helicopters - not planes - that Saddam used to gas the Kurds were from Bell Helicopter Textron and Hughes, which are both US companies. Any planes Saddam had have been grounded (and indeed, literally buried) since the No-Fly Zone was established after Gulf War 1.
So go check out that link and educate yourself, before the next time you go spouting off about things you know nothing about.
Fuck France
Oh, you don't want to get into that. France has much more effective curses to hurl back at you.

I urge slashdotters to read some european history
If it doesn't involve nonsense like orcs, mithril armor and little twerps playing 'witch' games, then no Slashdotter will read it.
I suggest Keegan's "The First World War" to dispell any Merikin foolishness about how cowardly the French are in wars. The US showed up in the Great War well after the shit went down. Also, according to cca 1941 GOP policy, WWII was "Roosevelt's War." Godless unpatriotic queers!
Comparing it to Windows will be a moot point, since El Dorado is going to have a 40% larger code base than XP.
You keep using that word. I do not think it means what you think it means.
If Jesus wants me it knows where to find me.
I don't consider 72% in favor of a "slim majority"...
Sure, maybe 72% were in favour of the war after the invasion had begun. That is because 10-20% of Americans appear to be mindless automatons who automatically support their president during wartime (a sensability that is much lauded by the American media).
In the weeks and months leading up to the war, public opinion fluctuated daily (also depending heavily on what question was asked). Go read some of the other surveys on the site you referred to, including this one, taken shortly before the war began, in which the exact words "slim majority" are used to describe support for an invasion without a new UN resolution.

I vividly recall a physics professor of mine, about 25 years ago, who worked on fusion, saying: "It will be almost impossible. The neutron flux for efficient, continous power generation is so intense that no known materials could sustain the exposure". He talked about materials getting brittle- the materials in closest contact with the fusion core would fail (in weeks, months) and there was no cost effective way to deal with that for long term, stable, low-cost power generation.
Well, if you look at the topics of a conference (11th International Conference on Fusion Reactor Materials) in Japan just a few weeks ago, that problem has not gone away yet.
I mean, besides that whole concept of "liberty" and stuff... oh, and they:
*aided us with ships and arms in our most important time in removing King George from the colonies
*provided money for the expansion of our navy to defend our trade to the Barbary Coast
*became our number one trade partner when no king's nation was buying American goods
*admired and respected us that they acted in same manner to start a revolution for their people
*loved us so much that they gave us the Statue of Liberty, and we loved them so much all of our fashions and opinions came from France
*is our oldest national friend, and the first place that really recognized our sovereignity
opened our cultural gates to Europe when we needed help
*has been our staunch ally on the security council, believed with us that the spread of communism in Vietnam was so important that they got involved first, almost religiously backed our initiatives until we freaked out and launched a war unprovoked
*generally put up with our crap, and we them, for generations, out of FRIENDSHIP
*And most importantly, they would LISTEN TO US AND WE THEM WHEN WE DISAGREED
Besides that, what has France ever done for us. And by saying "done for us" I mean the LAST TWENTY MINUTES. After all, America is not good on remembering the truth about France and America, who were, at one time, the only two democracies backed into a corner in the world, struggling for the freedoms of their citizens.
NEVER FORGET THAT.
Take that you anti-France bastards. We're old friends, it is about time you honored the contract, and listened to your friends, you petulant children.
By the way, we had larger influences in Iraq than you think. Read a little.
