EU Fusion Experiment's Financial Woes Get More Concrete
fiannaFailMan writes "An international plan to build a nuclear fusion reactor is being threatened by rising costs, delays and technical challenges. 'Emails leaked to the BBC indicate that construction costs for the experimental fusion project called Iter have more than doubled. Some scientists also believe that the technical hurdles to fusion have become more difficult to overcome and that the development of fusion as a commercial power source is still at least 100 years away. At a meeting in Japan on Wednesday, members of the governing Iter council will review the plans and may agree to scale back the project.' Iter will be a Tokamak device, a successor to the Joint European Torus (JET) in England. Meanwhile, an experiment in fusion by laser doesn't seem to be running into the same high profile funding problems just yet."
Wow, in the 50's it was any day now; 70's real soon now; 90's became 50 years; now 2010 we're at 100. That's a heck of a curve. In 100 years we'll be at only 200 years away!
The EU spends way more than that on agricultural subsidies every single year. I'm probably a cultural barbarian, but I happen to think that developing fusion, even if it will take a while, is more important than subsidising French wine.
As for all those "fusion will always be 50 years away" remarks: that's what happens if you never start. ITER could have started a decade ago, if everyone hadn't been fighting over where to build it. Fusion would be ten years closer if we had somehow managed to select a piece of ground somewhere in a reasonable amount of time.
Practical fusion will always be 50 years ahead, because that's what we are (inadvertently) paying scientists to say.
Scientist in lab: "Ha! Another positive energy run! Well, we'll just fudge the numbers so it looks like it took more energy to start the fusion than we got back. Can't jeopardize our funding..."
Nope, I don't buy it. Once fusion hits positive returns, there will be more money spent on it, to develop it to practical status. And the lab that first hits positive return will go down in history, famous forever.
Scientists working on fusion would love to succeed.
since governments fund research, not solutions, that's what they're getting -- research, not solutions.
I don't know how you can skip the research and go straight to the solution. If you know how, then please go do it for fusion, and make yourself fabulously wealthy as you solve all our long-term energy problems.
And if you don't know how, then stop bad-mouthing the fusion scientists. Kthxbye.
Far as I know there's been no progress, even in the lab, since then.
Then perhaps it is time to expand your knowledge?
We have built working toroid reactors since the 1970s. Just such a reactor, JET, is mentioned in TFA. The problem is no longer whether such a design will work. Nor is ignition the problem; we've achieved that years ago. Controlled fusion exists, here, now, in the present. This wasn't the case in the 1970s (well, there were Farnsworth fusors and H-bombs, but those are both significantly different cases).
The problem now lies in getting net energy out of it, and keeping the reaction going over long enough durations to generate useful amounts of electricity. This is indeed physically possible (see for instance the centre of the sun), it's just very challenging from a practical standpoint. The engineering hasn't caught up, in part because the number of testbeds for new designs is sharply limited. ITER is supposed to be the next such testing ground for new engineering solutions, but as you can see, it's having trouble getting political and financial backing.
Also, this "fusion has been 50 years away for the past 30 years" meme gets on my nerves. It's selective perception, and utter bullshit. People remember the promise of fusion, but forget that we were politically and financially unwilling to pay for it. The research wasn't going to just happen magically, someone needed to underwrite it.
Had we done the needed R&D decades ago, we would be decades ahead of where we are now. We didn't. You get what you put in, and in this case we put in nowhere near what we ought to have. Result is that we're behind.
