      For many years (almost 25 years) I have been convincing scientists that thermonuclear fusion in the Sun occurs not in the core of the Sun, but in the solar corona !!! But scientists are very stubborn, and do not want to believe the obvious. Why are scientists not accepting new breakthrough scientific ideas? There is an assumption, accepted by most scientists, that thermonuclear fusion in the Sun occurs in the Sun's core. But no one has ever actually confirmed this. This is just a guess, the fantasy of an authoritative physicist. Scientists are currently using two methods to achieve nuclear fusion: inertial confinement and magnetic confinement. But there is also a third method of achieving nuclear fusion, this is the repetition of physical conditions as in the solar corona. Nobody is using this third method to achieve nuclear fusion? In 6 months there will be a small prototype of a commercial fusion reactor. A commercial fusion reactor in 1-2 years! I propose a technology transfer for a commercial fusion reactor under a contract.

    Dr. Ruzic-
    Chemistry major here from Oregon State University. It’s been a few years, but I did take calculus-based physics and 5 terms of calculus. Solid A- average in all of those.
    This video was you at your best: you remind me of stories I’ve heard about Feynman, in that you are very very good at simplifying the science into something everyone can understand.
    I started the video by thinking “how the hell can you have molten Lithium flowing on the walls of the reactor??”. When you mentioned the voltage in the Lithium channels, for a second I thought you were going to say that the flowing Lithium would create its own magnetic field that would help the confinement of the plasma. When you talked about Force from B-cross-J, my jaw dropped just a bit and I thought “HOLY CRAP THAT’S AWESOME!”.
    When you started talking about your research and gave a mini-tour of your lab, I thought “....yeah, I won’t be surprised if he gets a Nobel Prize in the next 10 years...”.
    These were just some thoughts I wanted to share. This is possibly my favorite video you’ve posted, the contender being your Chernobyl video. I’d love to see more videos (as much as can/choose to share, of course) of the research that you do. It brings back a part of that Chemistry/Calculus/Physics chimera from my college days.
    Thank you very much, sir.

    What I love about this video is that as you were talking about the solution more and more, the more my train of thought about where you were going next became identical to the actual experiments. This is a really interesting way to flow the lithium across the reactor walls without adding much complexity to the reactor design. The fact that the temperature difference can turn the liquid metal into an electric motor that pumps the liquid metal across the surface of the reactor is just such an awesome way to solve the problem of being able to pull heat out of the chamber and circulate the lithium for fuel recovery.

    Now while the liquid lithium is outside getting cleaned can it be used for steam generation, or even pre-heating fuel being added like an economizer? Can some of that current generated in the thermoelectric effect be taken out for power generation, or is it all needed to push the lithium around?

    Questions:
    1. Do you envision a difference in performance between Li-6 and Li-7 in this setup?
    2. I take it that the surface tension of the liquid lithium will keep it in the trenches at the top where gravity would otherwise pull it out?
    3. Lithium boils at 1330 °C - you are confident that the heat transfer out of the device can maintain the lithium below this temp even when the fusion extends out to the walls?

    I want some time alone in your lab, LOL. So many awesome devices. I'm making a fusor myself at the moment, saving some cash for a high quality vacuum pump. Have my stuff set up for electrolysis of heavy water. Working on my screen set up and 1 inch thick acrylic vacuum chamber. I'm a ham radio operator so I have some high voltage transformers up to 10 Kilovolts and a variac to control my input voltage to the DC transformer. Hoping I can do some electrostatic confinement fusion by next year. I'm a beekeeper also, and we have the big fall nectar flow going on, and I'm doing treatments for varrora mites to get my bees pest free for winter. So right now my other projects are on hold until after the honey harvest. Hoping I can get some good videos of the fusor in star mode when I have things all ready to go.
    Last year I made a diy railgun, but the rails really wore out fast. After about 200 shots the rails were toast, and the projectile would not travel down them. There was too much slag and debris from previous shots. It was hard to take videos of it, because the emp it gave off when fired messed with the cameras.

    @magnustorque5528 Рік тому

    With brilliant scientists such as this guy involved that have a passion to achieve viable fusion energy and are tackling every challenge that presents itself by looking for innovations to overcome those challenges, this is going to happen.
    They already know what's required. They already know that's it's possible to achieve this on Earth. They know that there are no "brick wall" limitations that would prevent this from happening regardless of innovative effort.
    It will come together as it evolves (that's already happening). As these kinds of things evolve, discoveries that weren't conceived prior emerge, and often times can exponentially accelerate the process related to the objective.
    Fusion is the holy grail objective here, but Fission in the interim is a very fine close second that we already have perfected.
    Fission reactors this very minute could sustain all of our energy needs if we just proceeded to build the plants.
    The stigma and misguided fear about nuclear energy is what's holding this back unfortunately.

    Nice idea Dr. Ruzic. Does the lithium and the chamber wall eventually become neutron embrittled? What does the logistics look like for replacing/disposing of the radioactive parts?

      The lithium is not adversely effected by lithium, but you are right that the structural material can be. There is a lot of work going on to find structural materials which will anneal their damage automatically, and there are some possible candidates.

    Lithium-7 was used in the Castle Bravo nuclear test.
    Originally, they were supposed to use Lithium-6, but it was in very short supply and was extremely expensive.
    Using Lithium-7 instead of Lithium-6 resulted in the yield being 15 megatons instead of the expected 8 megatons.

    So, is the Lithium also the radiation shield? The neutrons from the T+D hit the Lithium and make more T that you can then extract?

    1. Why lithium doesn't produce cold flux? Why it is unique in this respect? It seems, this questions were omitted in the video.
    2. Btw, 3^3=27. And also 20 times smaller doesn't necessarily mean 20 times cheaper. The link between size and cost isn't obliged to be linear.

    • @illinoisenergyprof6878
      @illinoisenergyprof6878  4 роки тому +4

      Since the H is absorbed when it hits the lithium wall, it does not return to the plasma. The lithium does not saturate because it is flowing.
      Yes, I used to say 27 times smaller, but it isn't exactly a sphere, so I thought 20 is more likely. You are right that size and cost are not directly a one- to one comparison, but it certainly gets us far in the right direction.

  • @AOL18155

    Excellent video!!
    I have a question though. By using lithium over the walls, wouldn't the neutrons from the reaction (if using D+T) be creating more tritium, and thus, creating a need to replenish the lithium constantly?
    Thank you very much

    • @MrCasual14
      @MrCasual14 4 роки тому

      Isn't the current that creates the flow in the lithium supposed to move away the affected lithium so you can replenish the walls with fresh lithiem. I don't know.
