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.

In 6 months there will be a small prototype of a commercial fusion reactor. A commercial fusion reactor in 1-2 years! Power 100 kW. 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?

[@Chelnaka]

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.

@5:05 - How does having Lithium walls suddenly mean no cold flux from those walls?

Because the lithium is pulled out before it is saturated

@@manofsan molten flowing lithium covers the inner walls of the reactor, held on by surface tension, and flows into and out of the reactor. Distillation processing clears out the solutes from the lithium once removed, and is then recycled back into the reactor.

@@johnfedoruk so does that mean the molten lithium is hot enough that there's no cold flux returning from the walls to the rest of the reaction, and thus allows the full available volume to be of relatively more uniform and higher temperature?

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? Other than these concerns, your idea seems excellent to me.

[@magnustorque5528]

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.

[@extraintelligence]

Wouldn't it be closer to 30x smaller, given that (1/3)^3 = 1/27? Then again, I presume there are diminishing returns on the miniaturization since certain parts have to be a certain size regardless of the size of the fusion chamber (eg, thickness of the chamber walls).

Perhaps a Li-Al molten solution can expand the range of the concept if Li starts to boil off due to high temp. and low pressure. What is the order of magnitude for allowable LIH content? - LiH forms hard ceramic particles so the some upper limit of LiH concentration could impact flow. I've worked with large scale LiH production and I've seen the crystals grow into very large particles. Does LiH have any solubility in bulk Li liquid? Perhaps the temps stay above the LiH melting points. The Rankine cycle reference made me cringe.

[@CelticKnight2004]

With the hot lithium coming out of the reactor, wouldn't this mean the lithium has to be cooled? Could the cooling of this lithium, as part of it's cycle, be the extraction of the energy put in? In the process of cooling, convert water to steam, and create usable electricity? Or would the scavenging of energy from the lithium work counter productive to what's trying to be achieved?

[@lewisdoherty7621]

That was my initial assumption. I think in the drawing to simplify it he just had "coolant" so to remove heat. There will likely be loops going out and a heat exchanger. It may well be two heat exchangers with a intermediate fluid to reduce the possibility of any of the lithium leaks coming in contact with water.

[@georhodiumgeo9827]

I might be wrong but I see 2 problems, 1 the amount of lithium flowing “through” the reactor I would imagine is very small. The capillary action holding it in place would fail if it were too thick 2 the specific heat of lithium is less than water (still very high for a metal) and Li is 1/2 as dense meaning you would need 2-3 X as much flow to accomplish the same cooling as water. Still very interesting because you are essential cooling from inside the chamber. You might be onto something.

[@jagmarz]

@@georhodiumgeo9827 But the lithium isn't what's doing the cooling, it's just collecting hydrogen so cold hydrogen doesn't reenter the flux, right? The cooling is still inside the fins, if I heard correctly.

[@georhodiumgeo9827]

jagmarz from what I understood you are correct and I would extend that to say it would be difficult to impossible to use the lithium as a heat transfer mechanism in a meaningful way. This is the single most clever scavenger implementation I have ever heard of. The magnetic field keeps the plasma contained in the center of the chamber but you will have some stragglers hit the wall and cool down. When they return to the plasma they wreak havoc while they heat up again. These guys just absorb the gas with a flowing wall to remove it and replenish the wall later. Beyond me, I’m still trying to wrap my head around how much hydrogen will dissolve in liquid lithium. Next level stuff.

[@catchnkill]

@@Sidowse Tonycmac is very valid. He asks a very important question. You want to use fusion to generate electricity. How? Like the ITER you need magnetic confinement to restrain the plasma in the centre of the loop to start fusion. All the heat is in that plasma. You cannot allow the plasma to hit the wall. Then how to take the heat out to boil water to generate steam to drive the generator to generate electricity?

[@catchnkill]

@@Sidowse You mean fission? Fusion can potentially radiation free provided you do aneutronic fusion. You need to use materials that requires a order of magnitude higher temperature to start the reaction.
