Cold Fusion in a Breadbox Instead of a Bottle

rawbytes writes "For the last few years, mentioning cold fusion around scientists has been a little like mentioning Bigfoot or UFO sightings. After the 1989 announcement of fusion in a bottle and the subsequent retraction, the whole idea of cold fusion seemed a bit beyond the pale. But that's all about to change. A very reputable, very careful group of scientists at the University of Los Angeles (Brian Naranjo, Jim Gimzewski, Seth Putterman) has initiated a fusion reaction using a laboratory device that's not much bigger than a breadbox, and works at roughly room temperature. This time, it looks like the real thing." From the article: "Scientists have gotten fusion to occur in the laboratory before, but for the most part, they've tried to mimic conditions inside the sun by whipping hydrogen gas up to extreme temperatures or slamming atoms together in particle accelerators. Both of those options require huge energies and gigantic equipment, not the sort of stuff easily available to build a generator. Is there any way of getting protons close enough together for fusion to occur that doesnt require the energy output of a large city to make it happen? The answer, it turns out, is yes."

Neither one manages to produce positive net energy output.

      There's no particular reason to doubt it, and assuming it's true, it's not even particularly exciting or promising as a way of producing useful energy. "Fusion" is a broad term. Particle accelerators fuse nuclei all the time, and there's nothing unusual about doing it with beams that have been accelerated by an electrostatic field. A small tandem van de Graaff accelerator can easily be fit in a small room, and some colleges run them for use in undergraduate and graduate lab courses. The thing is, nuclei are small targets, so the cross-section for fusion is extremely small. Virtually all of the beam particles stop in the target without undergoing fusion, and all the energy spent in accelerating them is wasted. In a typical nuclear physics experiment with a beam hitting a metal foil target, the power required to run the accelerator is many kilowatts, the power deposited by the beam's kinetic energy in the target is in the watt or milliwatt range, and the energy used up or produced in the actual fusion reactions is a many, many orders of magnitude too small to be detected as heat.

      Not that there aren't interesting techniques to watch. ITER is almost guaranteed to work; whether it will ever be economical is a big question. Muon-catalyzed fusion is interesting because if you can stop the muon from sticking to helium so frequently (which some researchers claim to be able to do), you can have a single muon cause numerous reactions, and easily pay off the generation cost. Sonofusion is new, and relatively unexplored, so there's plenty of potential. Inertial electrostatic confinement is old and has only been making baby steps since then, but does keep on improving (I'd be interested in seing how some of the penning-trap gridless and magnetically-shielded grid designs work out), and has interesting potential to be scaled up to everyone's favorite, boron-hydrogen fusion.

  30. Well, what about these ideas .... by ankhank · · Score: 3, Informative

    Let's see -- they've talked about cracks in the electrodes, and stressed crystals.

    Can we make a better fusion device using precise fabrication tools? -- produce exactly the right materials and spacing to create tiny little accelerators, artificial crystals, to optimize this procedure?

    If so, can we make a "sea urchin" with a few thousand such little accelerators, all pointed precisely at a tiny pellet -- a miniature version of the giant laser devices currently being built?
    Build the capacitor, the accelerators and the fusion core all on a little chip, wind it up ...

    If so there'd be a nice pellet for for a fusion pellet gun to use to drive an Orion-type spacecraft. Even if it DID take more energy to manufacture than it'd produce, it'd be one heck of a good way to store energy for, um, rapid decomposition devices (things that go boom).

    Or, a wholly different approach --

    I've always wondered what would happen if someone manages to cause fusion to occur between a couple of Bose-Einstein Condensates.

    Make them out of, on the one hand, tritium atoms, and on the other hand, deuterium atoms. Result, one large 'atom' of each element. Very large. Then clap your hands. Fusion?

    Or better yet, use condensates of boron and hydrogen, of course.

    The boron-hydrogen method is described as currently being worked on (not using Bose-Einstein condensates -- using something like the Philo Farnsworth accelerator), if I read it correctly, here:
