The Japanese company proposes to transmit solar energy from the moon

The unusual concept of LUNA RING of the Japanese Shimizu Corporation suggests using solar energy collected by the natural satellite of the Earth using solar batteries and transmitting it to the Earth using microwave or laser radiation. According to the company's forecast, the energy thus obtained will be able to cover the planetary needs, even taking into account their increase by 2030 (the estimate is as follows: 13,000 terawatts) - the theoretical time to bring the concept to life.



Strictly speaking, we are talking about the idea of ​​surrounding the moon at the equator with a network of solar cells approximately 11,000 km long and with a varying width from several kilometers to 400. This will make it possible to use solar energy as efficiently as possible, given the absence of the atmosphere of the moon and the scale of the potential battery network .

Fully aware of the entire technical complexity of the enterprise, the company names the following advantages of LUNA RING. On the one hand, space flight to the Moon is not comparable in cost (both technical and financial) with relatively long-range space missions - to Mars, for example. At the same time, if the concept allows organizing an automatic - using autonomous or controlled robots - the production of auxiliary materials required for construction, then frequent space flights may become unnecessary in general. For example, processing the lunar soil with the help of special units (which, of course, also have to be delivered and assembled on the moon) will allow you to get water, ceramic materials, glass, oxygen, cement, as well as material for the solar cells directly on the spot.



The creators, as an illustration of the last thought, offer this:







What will happen on Earth?



Installed on the surface of the moon, special radiating antennas with a diameter of 20 km will transmit energy in the form of microwave radiation with a frequency of 20 GHz, received on Earth by specially built stations (which can be floating, taking into account their size - about 2 km.) - energy loss at this frequency will be only 2%. A diagram of this process is shown in the figure below:
