Energy is one of the biggest problems facing human beings. Nuclear fusion may be the ultimate solution. Who can realize this technology is of immeasurable significance. MIT researchers have announced an important development. Its SPARC fusion project has been proved to be feasible and can output 10 times the energy. Nuclear fission and fusion have been learned in physics in middle school. The former is that the big nucleus splits into small nuclei to release energy, while the latter means that small nuclei become big ones to release energy. The sun is nuclear fusion, which gathers hydrogen atoms into helium atoms, burning 620 million tons of hydrogen per second. < / P > < p > the difference between the two technologies used in weapons is the difference between hydrogen bomb, which is more than 10 times more powerful. However, in the civil field, that is, the difference between nuclear power plants. At present, nuclear power plants are still based on fission. The nuclear power plant with fusion technology can’t be used, because it’s uncontrollable – actually, it’s not uncontrollable. Human beings can control nuclear fusion to some extent, but the problem is that the energy used to trigger fusion is higher than the energy generated, that is, the Q value (energy gain factor) is less than 1, which is feasible only when it is greater than 1. < / P > < p > in the current nuclear fusion power generation technology, the Tokamak with superconducting magnetic control and plasma is the mainstream. There are the Dongfang super ring project in China, and the ITER thermal nuclear reactor project jointly constructed by the international community is also the same route. < / P > < p > in 2018, MIT teamed up with a company called Commonwealth fusion systems on a new nuclear fusion project SPARC, which aims to create commercial fusion power plants within 15 years. Recently, MIT released the latest progress of this project. Seven papers from 47 researchers from 12 research institutions have been published in the Journal of isoparticle physics. < / P > < p > these studies have confirmed that one thing is that SPARC fusion project is feasible, which can at least achieve the goal of Q value of 2, that is, the input energy of 1J can generate 2J energy, and the extra 1J is the energy generated by fusion. The Q value of < / P > < p > 2 is not all. The calculation shows that the project can reach the level of q = 10 or higher, that is, 1J energy can produce 10J output, so the income of power generation will be greatly improved. In addition, nuclear fusion projects are burning money one by one, and the investment in ITER projects with international cooperation is expected to exceed 22 billion US dollars. However, MIT did not disclose how much SPARC project will cost or how these huge investments will be spent. Therefore, fusion power generation is still far away.
