An example of an unlimited source of energy is the process of nuclear fusion occurring on the Sun (and other stars), as a result of which the temperature at the surface of the star reaches 1.5 million, and the core is heated to 13.5 million degrees Celsius. In terrestrial conditions, such gigantic temperatures can be achieved only with the help of a special reactor - a tokamak.
Scientists of the recently established British company Tokamac Energy have made significant progress in this area. Using the ST40 installation, they were able to "warm up" it to 15 million degrees Celsius, which is comparable to the temperature inside the solar core.
Briefly, the reaction of nuclear fusion consists in the fact that the light nuclei of deuterium and tritium, combining, form heavier helium nuclei with the release of a gigantic amount of thermal energy.
Tokamac Energy hopes to achieve success through a so-called compression fusion process, in which currents flowing through two symmetrical coils form two rings of plasma around them.
If the current in the coils is reduced to zero, then these plasma rings, connecting with each other, form one. In the process of joining the rings, a huge amount of energy is released, which heats up the plasma.
The goal of British scientists is to bring the plasma temperature from 15 million to 100 million degrees and make the research project commercial by 2030.
