    A couple of corrections:
    At 3:13 I said the processes the wrong way round. The FISSION part is only there to aid the FUSION part. And ICF is Inertial Confinement Fusion not Internal. Sorry about that.

    I strongly recommend everybody to take a look at the video that Improbable Matter made in response to the Real Engineering one about Helion. He has worked in the field and can explain all the challenges of fusion in great detail.
    What happened on december 5th was historic, in the sense that is the first time we extract more energy that we put in without using an A-bomb as a trigger (we cannot ignore that we had been building fusion reactors that work as insteded since the 50's, they are just single-use only). But if we write down a list of the engineering problems we still have to manage that we don't know how to solve, it's amazing how astronomically far we are from a comercial fusion reactor. I'm sorry guys, but apparently we are going to get out of this energy-poverty well with fission, and the sooner we start the better...

    I visited JET (Joint European Torus) in '96 at a physics tour in England among other things. We were shown the torus (Magnetic Confinement Fusion) and the facility. They told us that they had to phone the power-stations in advance in the area when an experiment was due or else the entire area (a small city and two or three suburbs) went without power. JET used that much power! And it's rather small in comparison to what it uses; kind of a small living room or an apartment with a single room.
    Edit: I forgot to say, that the power-stations was able to turn up to full power and THEN the experiment could take place without any bother.

    If I'm not mistaken, the main source of Tritium is Fission Reactors. So, ironically, in order to scale up Fusion we may need to scale up the number of Fission Reactors, with all of the problems associated with that. Unless we can find a different isotope to use in the fusion we're going to need to have nuclear power in a lot more places. Apart from the dangers and mess they make, they are also very expensive, slow and complex to build.

    I'm glad you're being cautious to make sure people know that the practicality for this is still decades away. But I think the step taken here is more than just "a large step". Most people thought it was fantasy before (not even sci-fi) because of how long it was taking to take this one large step. Now that this has been confirmed to work on this scale, so much more support for it will begin pouring back in. More *human excitement* was produced from this reaction than was put in.

    It's a step, it's a milestone, but not yet a breakthrough. I'm so excited to see this happen in my lifetime!
    I think a big step forward would be finding a way to not need such high purity precursors. Ultrapure water in of itself is a nightmare to purify and store (ask anyone in the semiconductor fabrication industry). When dealing with heavy water for fusion, I can only imagine the headache associated with ultrapure heavy water. I believe that not needing ultrapure grade heavy water I think is a possible next milestone, and possibly not needing heavy water could be another one, though I have less faith in that idea, since deuterium is the most thermodynamically efficient precursor as far as I know.
    DISCLAIMER: my background is materials science, chemical engineering, electrochemistry, and molecular physics. I am not a nuclear chemist or physicist. My only exposure to nuclear fusion work is reading the scientific papers associated with the work out of my own interest.

One facet of chemical engineering, specifically reaction engineering, is being able to produce a product more reliably, like tritium as you stated. But another frontier that a lot of people work on is to be able to perform the same reaction at a lower energetic or economic cost without sacrificing too much yield. So you are right to be worried about the yield loss if you took this approach. You are trying to have it both ways: low cost and high yield.

    Fusion will be great when it happens. I had a chance to work briefly on ITER, and I can say that it is an experimental facility that MIGHT overcome many of the limitations of prior tokamak reactors. In any case, commercial fusion power generation is still a couple decades off.
    In the meantime, we should be pushing for molten chloride fast reactors (MCFR). These are fission reactors, BUT without many of the concerns that plague traditional fission reactors in current operation in the US, and with many of the advantages of fusion.
    MCFR does not use water to slow neutrons down or to cool the reaction. Instead the reaction happens with fast neutrons, which can much more completely use up the fuel, resulting in only short half-life waste products, and can use a wider variety of materials as fuel, including natural/depleted uranium and thorium, as well as much of the existing spent fuel waste stockpile (which still contains a lot of fissile material that simply could not be utilized by the slow neutron reactors). Since the system doesn't use water for primary cooling, there is no high pressure steam to contain, thus reactor vessels can be made much more cheaply. And the reaction is self-limiting. As the temperature increases out of normal operating margin, the liquid reactants expand, slowing down the reaction.
    Key advantages:
    Can't melt down
    Can't have steam explosion or release of radioactive steam
    Self regulating
    Broad range of fuels
    Little new waste and using up existing waste
    TerraPower and Elysium Industries are both working on pilot plants to prove commercial viability.

    Why are even science/tech channels that should know better spouting this B.S. The overall power input of the whole system was about 400 MJ. They produced about 3 MJ. They did not produce more energy than what was put into the overall system. This garbage that it produced more is from the fact that the lasers only delivered about 2MJ to the fuel.
    Power delivered to the fuel: 2 / 400 = 0.5% of input.
    Power produced: 3 / 400 = 0.75% of input.
    Yes this is an important milestone but telling people more energy was produced that used is just flat out wrong and people aren't going to look into or even understand the distinction when this line is being pushed by those they consider experts.

      Yep, also it's important to note that the "energy generated" wasn't converted into electrical, I'm pretty sure they were just measuring the thermal energy, a large percentage of which would've been lost in any conversion.
      I've yet to hear a realistic pathway for generating electrical power from inertial confinement, it just looks like blue-sky research to me with no practical end goal. Tokamaks and stellarators on the other hand, do look like they could produce real power plants but may end up being far too expensive and complex to get any commercial value from.

      I would love to know what each of those tiny pellets cost to make. Multiply that by millions a week, and the electricity coming out of that thing will cost a fortune. And the statement about no radioactive waste is false. Over time, the neutrons coming from the fusion will make the walls of the reactor slightly radioactive, weaken the metal, and the metal will have to be discarded as low level radioactive waste. You can't recycle it, since there is no way to remove the radioactive isotopes made by the neutrons.
