We are damned good at an uncontrolled fusion reaction tho. We understand how to start them up. We just don't know how to do it in a bottle. The problems make disposing of some spent fuel rods seem trivial compared to fusion without blowing up the city if the plasma gets away from you. The plasma getting away, just seems to make the fire go out. I live the next city over from the Lawrence Livermore Labs and they have been studying fusion for a long time. They know very well how to make uncontainable fusion. But getting a positive energy result out of the reactor is the problem. They have got out more energy than they put in, but not enough to pay for the process. https://www.llnl.gov/news/nif-achiev...e-fusion-yield Luddite can go back in to the business of making thin film energy capsules. The thin film deposition systems we built for the Laboratory for Laser Energetics ( University of Rochester, Omega project) was used to put thin film coatings on the large laser optics used in the laser beam line. Without the coatings the power of the laser would destroy the glass. When NIF was built, the power of it's laser was many times that of the Omega system. Lawrence Livermore went out for bids for the necessary coatings but nobody could meet the necessary laser damage threshold. They ended up having the coatings done (at least initially) in the system we had built for Omega because it was the only one that could come close to meeting the specs. It was more "know-how" by the thin film engineers than the system but it was a feather in our cap none-the-less. Turns out the laser damage was probably one of the reasons the project at Lawrence Livermore was abandoned, although not the only reason. The power in those laser beams is just too much for many of the optics, even with highly sophisticated coatings. The optics used are incredibly expensive to make, polish and coat. |

The Omega project at the Laboratory for Laser Energetics and the NIF project at Lawrence Livermore National Labs are both pursuing nuclear fusion among other things. Huge laser bays focusing multiple, high powered laser beams onto a tiny pellet of deuterium simultaneously and only for a few microseconds. In the case of the Omega system the power delivered on the pellet can be as high as 60 terawatts. The larger NIF laser can deliver 500 terawatts. The instantaneous temperature of the plasma created can be many times the temperature of the sun but it still requires more energy "in" than it produces "out". The NIF laser has achieved about one third the power required for a laser induced nuclear fusion reaction. I am certainly not one to judge but based on my limited knowledge of this research, we are still a long, long ways to having viable nuclear fusion reactors for home or local power generation. https://en.wikipedia.org/wiki/National_Ignition_Facility Gosh, so I probably won't be able to buy a new toyota with a nuclear fusion engine in my lifetime? Darn! Upon re-reading the Wiki article on the NIF program it appears that they gave up trying to create laser induced nuclear fusion. Just wasn't feasible and after years of attempts they couldn't come close. Doesn't mean another method may come along but it still requires an enormous amount of energy. So, the 190 beam NIF laser is now used for it's intended use, the development and testing of nuclear weapons under conditions that do not violate the nuclear arms testing treaty. Should make your day. :-) I’ve got my eye on a slightly used deLorean. Just say you bought one. Just like your other lies. |

He's already got the quarter-mile driveway and Maryland-red barn in which to store it! Hope his two owls don't poop all over it. |
