New Advances Bring Fusion Closer to Reality

An anonymous reader writes "The Christian Science Monitor reports on new advances in nuclear fusion research. For years we've been waiting for the technical breakthroughs that would make cost-effective fusion energy a reality. Are we getting close, or are the problems insurmountable?"

    I object to the insinuation that we are the ones splitting the nuclei of the radioactive elements

    Well, fine. But you can say that by refining the uranium, and bringing sub-critical amounts of together in a pile, or supercritical amount together in a bomb, we are utilising the nucleus's innate tendency to split, and to thereby trigger a chain reaction in nearby uranium nuclei, in order to generate a self-sustaining level of radioactivity that would not have otherwise occured.

    You could also say when making tea that we are not the ones boiling water, we are merely allowing electricity to flow through a restisting metal rod, which generates heat which when transfered to the water causes a rise in temperatre to boiling point that would not have otherwise occured. But that would be very, very pedantic.

    Is this an Ask Slashdot?

    If so then my answer is yes! I mean no! err..What was the question again?

    IANANE (I am not a nuclear engineer) but if I read that article correctly then it seems some of the many problems have theoretical solutions. In other words, it worked in the simulation. We need to get this thing built and do real tests before we can even think about being "close" to having fusion plants.

    They can't even decide where to build it! Why can't I vote to spend my (US) tax money on putting one of these over here. Even as a test bed it will give the contry it's in some home field advantage.
    You can use my back yard if you want! Don't listen to my whiney neighbors, they don't know what's good for them!

    since when does a fossil fuel power plant produce radioactive waste? :)

    Take a look at some of the research and data on how much naturally radioactive particles are released into the atmosphere through burning of fossil fuels, you'll probably be surprised. I believe it's a few orders of magnitude more than the amount generated in current fission plants.

    Sorry to be a nathering nabob of negativism, but...

    Practical nuclear fusion would be the best thing that ever happened to our planet: we'd lose our dependence on the Middle East for energy, and dramatically cut pollution. If it were up to me, I'd launch a nuclear fusion program on the scale of the Manhattan Project.

    However, the Bush family and that crowd will never allow nuclear fusion to become a reality - they make too darned much money on oil, and cash is all they understand.

    Not to reveal my age, but when I was an engineering student in the early 60s the big science news was that flat screen TV was only 2 years away, and that CRTs would be rendered obsolete. Flat screen TV was perpetually 2 years away in the future for most of my life, but it finally did arrive.

    Our goal should be to have commercially useful fusion energy in operation by the end of the 21st century. It's vital, but not easy, for the public to support such long-term goals. That's particularly true when we can't visualize the links in the chain that will connect now with then.

    The actual breakthroughs that make energy power cheap and safe are likely to come closer to the end of the century, and we can't imagine what they might be. Still, we must support constant inquiry and scientific research to create the fertile conditions for breakthrough discoveries.

    The only reservation I have about supporting big science is a serious one. Money should go for science, not to feed the egos of the pricipals. The bigger the project, the harder it is to assure that.

  6. Re:Reason for Low Funding by R.Caley · · Score: 5, Insightful
    People want a return on investment before the next election, not 30 years from now.

    I think you are missing the point the writer was making. The 30 is a constant, ie we are always 30 years from fussion. This is not a return in 30 years, but a return an infinite amount of time in the future.

    Now, I think the fusion experiments are worth funding because they are fun. I think it's a shame that the political environment is such that the scientists need to pretend there is gold at the end of the rainbow, when the rainbow is so beautiful itself.

    We aren't talking big money here in government terms. Eg IIRC the proposed ITER budget is 10 billion Euro over 30 years. The EU pours approximately 100 billion into the common agrecultural policy every year and I presume the USA is operating on basicly the same level, just to prop up buisinesses who produce food no one wants to eat.
