British scientists from the University of Newcastle have developed a technology for storing and storing energy using "thermal power units". Its prospects are so great that a new company, MGA Thermal, has already been established, which is starting the construction of a plant for their production in South Wales. The name is conditional, the expression "Miscibility Gaps Alloy" is also used, which can be translated as "a very porous alloy" or "a material with a large number of micropores."
To describe the technology, its authors compare it with a cupcake with chocolate chips. The thermal conductivity of the dough, cake base, and chocolate is different, so when heated, energy is quickly transferred to the chocolate and it melts, but the whole structure remains intact. We can move the cake wherever we want and it will stay hot for a long time until the chocolate cools down. Also the power unit - it can be used for simple storage of thermal energy, for transferring it to other objects, for generating steam for a generator, etc.
The materials from which the thermal power units are made were not disclosed. However, it is stated that they are not toxic, not explosive, do not pose a threat to the environment, and are still cheap and affordable. Therefore, power units can be taken with bare hands, created in any quantity, stored without special conditions. Also, after some modernization, it is convenient to use them at old coal-fired power plants, so as not to close them immediately, but to operate during the transition period, but no longer burning coal and not creating emissions into the atmosphere.
At the same time, a working prototype of another alternative energy storage system is already being built in Scotland. It's called Gravitricity, and it's based on gravity.
