US is preparing a thermonuclear breakthrough

It is difficult to overestimate the benefits that the energy of the processes occurring inside the stars, which are based on thermonuclear fusion, could bring to mankind, and according to the physicists at the Massachusetts Institute of Technology (MIT), this may soon cease to be fantastic. MIT scientists, together with Commonwealth Fusion Systems, have announced that they are ready to build a fusion reactor within 15 years.




In the 20th century, mankind was able to curb the energy of nuclear fission, in which the atomic nucleus is divided into two nuclei with close masses, which is accompanied by the release of energy. Nuclear fusion is the reverse process, consisting in the fusion of heavier atomic nuclei from lighter ones. So some stars, including our Sun, release energy from the conversion of lighter hydrogen to heavier helium. The synthesis is accompanied by the release of a colossal amount of thermal energy, which people have long learned to turn into electrical energy.

The first attempts to build thermonuclear reactors began in the 40s of the twentieth century, but the main obstacle to progress was the inability to create a reactor capable of withstanding the process of thermonuclear fusion. MIT physicists are sure that they have found a solution - it will become a compact SPARC tokamak (toroidal chamber with a powerful magnetic field inside), which will allow holding a hot plasma, thereby ensuring the synthesis process. According to scientists, the resulting reactor will be able to generate 100 MW of thermal energy, which will be used to create 10-second pulses. According to the developers, this energy is enough to power a small city. The next step with a positive result will be the construction of a 200 megawatt reactor.

The magnetic field for the reactor will be generated by yttrium-barium-copper oxide superconductors magnets, which make it possible to maintain an enormous magnetic field. A magnet of this type, built by National High Magnetic Field Laboratory, can create a 32 T field (Tesla). For comparison, the magnetic field that creates a spot on the Sun is 15 T, and the standard MRI apparatus is 1,5 T.

It should be noted that MIT scientists are not the first to try to curb the energy of stars. The ITER reactor of the same company is planned to be commissioned in 2025, and the British Tokamak Energy is working on the development of ideas for creating even more powerful reactors.

    compact tokamak

    Well, at least they explained what TOKAMAK is. Who and where invented and implemented it once.

      What is this?
      ... toroidal chamber with a powerful magnetic field inside

      Move on
      MIT physicists are sure that they have found a solution - it will become a compact tokamak

      Obviously, we are not able to search for information in the material.
      Well, and if you need special details, you should go further to the Internet. This is still a news resource, not an encyclopedia.

        Boris, I know what a tokamak has been for 50 years. But you obviously have problems with humor and sarcasm.

      "TOKAMAK" is a fat dog that lives overseas and urgently needs a lot of money for a grand project. Where else can the mafia take money from, only from taxpayers, so that they can then saw it.

      Soviet scientists came up with. In Russia, work is also underway on controlled thermonuclear fusion! For some reason it seems to me that people do not need cheap energy, in any case, the global oil and gas lobby is very, very against it!

    Yes Yes Yes. Of course. I believe. This song is about 60 years old.

    All the principles and technologies for the production and further conversion of nuclear energy or cold gas are fundamental reasons for the impossibility of further progress. The whole problem lies in the fact that in all processes there is no ideology of energy concentration, its phased transformation without significant loss of potential in the transition stages.

      Since when is low efficiency with high performance relative to analogs a reason to abandon development? According to this logic, it is urgent to abandon the use of nuclear power plants. Can we only warm the water? Well then, this nuclear reactor is in the furnace!

      With the D + T reaction, direct conversion will not work because the vast majority of the energy is carried away by neutrons.
      "The whole problem lies in the fact that in all processes there is no ideology of concentration of energy, its stage-by-stage transformation without significant loss of potential during the transitional stages." And today, tomorrow, not everyone can watch ...
      You will never achieve less than one conversion.

    All this hype for the money. Although the fusion is tamed, it is partially true, the whole trick is that you need to spend four to five times more energy on it than it can give. So for now, all this can be used only for fundamental scientific purposes. And for commerce, if only under the cut laughing then yes.

      Well, well, it takes about 0,1 MeV to overcome the Coulomb repulsion forces, and 17,6 MeV stands out. Losses, losses spoil everything.
