The British have made a great breakthrough on the road to building the first functional nuclear fusion reactors that will provide the world with a cheap, safe and ecological energy source suitable for the 21st century.
This is another great achievement of the Tokamak Energy engineers. Last year, in their artificial sun called ST40, they managed to produce a plasma with a temperature of 15 million degrees Celsius, so a million higher than that prevailing inside the Sun. The next goal is to achieve a plasma temperature of up to 100 million degrees Celsius. Scientists plan to achieve this in the next 2 years. Then the production of energy in the nuclear reactor will become efficient and profitable.
These visions sound beautiful, and to confirm their imminent implementation, scientists have just presented the effects of their hard work in the form of the latest and most advanced HTS magnets in the world at the moment, made of high-temperature superconducting material.
Amazingly, according to the company’s plan, magnets with such properties were to be created only at the end of 2020, but scientists managed to prepare them now. Thanks to them, work on building a functional fusion reactor will now be significantly accelerated.
The HTS magnet called REBCO is made of rare earths, barium and copper oxide. This conductor cooled magnet created a magnetic field of 24.4 Tesla, at 21K, in a cold hole with a diameter of 50 millimeters, which is a world record. In superconducting terms, 21K is a relatively high temperature. In addition, HTS magnets are extremely durable, easy to install, very stable, reliable and simple to manufacture darknethub. We keep our fingers crossed for the British, their technologies and the ST-40 reactor itself.
It is worth emphasizing here that when in 3-5 years the first practical fusion reactors are connected to the power grid, they will not be perfectly perfect devices. Their development will last many decades, so new materials technologies and methods such as, for example, scientists from the University of Washington, testing zeta contraction (see here), may in the future prove to be beneficial in improving artificial suns.
