The development of moon bricks capable of generating energy began in Europe

The European Space Agency has ordered a series of studies to develop a technology for the manufacture of building materials from the lunar regolith. Today it is clear that just mixing dust and soil with cement is not enough - "moon bricks" must perform many atypical functions. A new study is devoted to the question: can they be used to accumulate the energy of the Sun during a lunar day in order to use it on a lunar night?

The conditions simulated in the test chamber are as follows. At first, 14 Earth days, there is constant heating at temperatures up to 127 ° C and low pressure. Then the camera is cooled down for the same period to -173 ° C in complete darkness. The task set before the scientists is as follows: to develop the structure of a brick that would not have time to cool down during a moonlit night.

By itself, a permanently warm brick is already good, because the lunar colonists' dwellings will not need to be heated during the night. But is it possible to make it even more efficient, to achieve such a level of energy accumulation that it would be possible to connect a simple heat engine to the wall of a building to generate electricity? Theoretically, this is quite realistic, in practice, the study has just begun and the result is not yet obvious.

The project is also interesting because its success will open up new prospects for the development of the solar system. At least up to the level of Jupiter's orbit, there is an abundance of sunlight, and if you learn how to create ultra-high-capacity batteries, future expeditions and colonies will receive an excellent source of free energy.
