      But i cannot imagine how to build economical reactor on base of neutronic DT reaction.
      Today we only can state that if Tokamaks will be big enough, they will produce net power.
      No doubt.
      In ITER 840 m3 plasma is projected to produce 500 MW fusion powe for 3600 seconds.
      Then next shot.
      In about one year I am sure the condition of first wall and other critical components facing to plasma should be revised.
      If maintenance neede plasma facing components will be strongly radioactive and need remote handling.
      There 18 toroidal magnets weighing 310 ton each.
      Vacuum chamber weighs as far as i remember about 5000 ton.
      I quote these numbers only to show how costly maintenance will be.
      New creative idia is needed allowing us to go to aneutronic fusion.
      But ITER is projected for plasma temperature 15 keV.
      DHe3 reaction needs on order of magnitude higher temperature.

    I fully understand that the scientists in this field are painting a rosy picture or leave out some details that would spark questions.

In reality, actually producing meaningful amounts of energy via fusion is a lot closer to the year 2100 than it is to 2050.

    If they can get that projectile and energy food that ignites then we could have a machine use fluidlike dynamics to predict the flow and maybe use multiple explosions in an order in dynamics and instead of cancel waves, build bigger energy waves. Like when you push a swing while it’s swinging to give it more energy or slow it down. A series of explosions detonated by projectile and then using the dynamics to carry the chain reaction or something. Magnetic fields can help guide and circulate the flow maybe.

      That is the mission statement of the NIF, it is to do research in understanding how fusion works in thermo nuclear weapons sometimes called hydrogen bombs. It has only recently been hijacked into a mission that will produce hyperthetical power plants. BTW, all of the energy that comes from so called hydrogen fusion bombs, only a small part is really from fusion. It is more acurate to describe them as Fission/Fusion/Fission weapons since most of the energy comes from the uranium blanket. Teller describes them as Super A bombs, fusion makes fission go much better.

      They already increased the gain by a factor of 1000 so 7 or 8 times more is maybe achievable in the foreseeable time, but on top of that they'll have to come up with a way to reload the machine with targets for a firing rate of 10 Hz, about the rate of fire of a Maxim gun. From my layman perspective, it seems like inertial confinement has a lot more challenges to overcome to go from experimental to industrial when compared to toroidal magnetic confinement.
      On the one slide, they talked about bringing down the cost of a pellet down to 30 cents. A typical coal fired power plant of about 750 MW consumes about $330 in coal in 1/10 of a second.

    Though there are sceptics aplenty, and while it’s true it is a very difficult task to create a star on our planet, the fact is that fusion energy has been created and is being scaled up. On top of it all, achieving a succesful scaled up fusion energy power plant is of vital importance to achieving a long held goal to leave our planet better than we found it. However, if it proves too elusive despite all our best efforts and expenses, then we still have our natural, gravity confined, succesful fusion plant in the sky.

    There are still many steps that have to be taken, and problems solved, to get to practical fusion power. Many talk about getting to higher Q values, but even a Q value of 1000 would not matter if the reactor costs too much to build, or keeps having to be re-built because the plasma destroys the materials. If we get to reactors that work, at all, in the next 10 years, look to many, many more years before the technology matures to be both reliable and economical against other energy sources that exist now, and are expected to become ever lower cost in the next 20 years.

    On inertial fusion, one thing needs to be made clear again: so far, the energy input of the entire machine is still much higher than the fusion yield, only the energy that arrives directly at the pellet to be ignited is lower than the yield! Therefore, the energy yield must be at least 15 times as high as the energy that reaches the pellet. Also, tritium must still be used in inertial fusion, which must first be bred from lithium in a nuclear reactor and is extremely expensive. Per ignition, and 1-10 per second are needed for operation, costs of 100K to 1M dollars must currently be expected. A stellarator will certainly run without tritium as fuel, possibly also without deuterium.

    The big problem for nuclear fusion to become the power source of the future is rarely mentioned. This is the fact that the tritium needed for the operation of a fusion reactor has to be produced by the reactor itself. It is possible to breed tritium in a fusion reactor but producing enough of it will probably turn out to be impossible. The reason for this is that each fusion reactor produces one neutron that could in principle be used to create one tritium atom. But inevitable neutron losses and losses in extracting the tritium will cause the yield to be far less than hundred procent. The only hope to make the losses up is to utilize nuclear reactions that produce more neutrons than they consume. Nobody knows if this will be a solution to the problem.

      Not to say you are wrong, but it's also important to realize that just because a couple of times in the past an idea that seemed futuristic and impossible turned out to be actualized, millions of other ideas that seemed futuristic and impossible turned out to be just that.
      Turning over known science and the status quo is extremely rare. Newtonian physics wasn't overturned by Relativity, which wasn't overturned by Quantum physics, they built upon each other and apply equally well, depending on size and speed. Fusion, as is being looked at now, isn't such a case.
      To your other point that even if it doesn't ever work there may be discoveries made during the research that may be of great unknown benefit (whether in technologies or simply in knowledge) seems reasonable, but it is just as, if not more so, reasonable that if the billions of dollars being spent on fusion was instead spent elsewhere (there are only so many science dollars to go around) even more benefits would arise from that research.

    Where is the super heated Helium? How do you transfer the heat from He atoms to boil the water? Where and how we separate the H from He and then extract the He from system? Self sustained reaction do not make sense if the fuel (H) is consumed, does He atoms breaks into Hydrogen? Is it better just boil the water using all that electricity and magnets and the energy to produce Hydrogen isotopes? How do you ionize H atoms and how ions can turn into plasma and move through the air atoms? Ionization only happens in liquid not gas/air.

    Great talks. Always interesting. Fusion energy can be low carbon but is not inherently sustainable because the fuel will run out relatively quickly. Also the product helium does not cycle back to fuel, deuterium and tritium, so not sustainable. Really nice science though.

    • @evilpanky
      @evilpanky 13 วันที่ผ่านมา +2

      The plasma produces neutrons that carry away 80% of the energy of the fusion reaction. These hit and heat the coolant, making it hot. This coolant then goes out to power the turbine! Most of the remaining 20% of the reaction power stays in the plasma as charged particles, helping to keep it hot enough to keep the fusion reactions going!

      @@JohnDunne001 Speaking theoretically about an experimentally proven set of technologies; on fusion generating helium and able to convert hydrogen....
      There are two things working for us, the direct production, and the indirect enablement to capture helium from the aptmosphere and run the machines or vehichles required to caputure it. Hydrogen based fuels are energy based to produce, so at least we get unlimited energy and rocket / jet / car fuel. Helium doesnt just dissapear into space, we just relied on helium being relatively easier to aquire from underground repositories and low efficiency air capture technologies.
      Ultimately, when energy is fully abundant, we would be able to aquire resources easier, and thus make more fusion reactors with said resources in a slightly positve reinforcement loop.
      If we start running out of resources on earth, we can mine the whole solar system and recycle better (restore sillica for instance) and virtually never run out.
      How do we reach it?
      Having fusion reactors on a pathway in space to turn cargo water into oxygen and hydrogen as fuel, for refuling smaller ships over hops. Then the channel flown in space can be a space road, with sparesely spread out space drones following behind the ship literally launched from the station into another station. The drones purpose is to collect the dispelled ions (H2O, from recombining in combistion) by the rocket, given the rocket has charged its expelled gas via ion thrusters.
      The drones attracts water, curving its trajectory into collisions, and these drones are positively charged with zenneck surface waves which are positive pulsed surface charge. It can attract the ship's expelled gas.
      Multiple drones shot at different times and speeds can capture most water but not all. The drones use slight fuel to slow and aim, and the recepitcal of the drone can capture ions too. The station shoots drones equally in both direction. Each time, balancing it in space. Re-capturing drones from a previous station in the line.
      Thus it may be called a water collector or scientifically a 'Zenneck Samudra drone' meaning 'a drone with positively pulsed electrified surface where water gathers'
      Cheers all, feel free to spread the idea. This was an original idea of mime, that I'm aware of, based on @e.t.h.e.r.official on IG's description of the B-52 secondary ion thrust electro-mechanisim, and years of expensive research on electromagnetic theory and its underlying applications and evidence.
      If a similar ion thrust enginer was used on earth, no recaputre drones are needed, and addding a positively charged leading edge will attract negative ions expelled, causing them to move forwards and create forward thrust. Not sure if this applies to rockets in space, but worth a try, as it may operate a bit like an Albuquerque warp drive?

    I am astounded by the level of ignorance in these comments here. Fusion is the most technologically challenging project in the history of mankind. So how can anyone wonder that it takes a lot of time ? - and the progress is undeniable. Fusion is now done routinely everyday. So people here in the comments talking about it beeing 20 years in the future are either ignorant, stupid or both. Fusion is NOT science anymore it is engineering. It's pretty obvious for anyone with just a small bit of sound reason that ITER will be a huge succes despite smaller setbacks. It's a very good idea that they build it large, so it can convincingly demonstrate the feasability of fusion power.
