Japanese scientists donated energy by air at 55 meters

Transmission of energy
Japanese scientists from the JAXA research center managed to transmit energy wirelessly over a distance of 55 meters. According to the researchers, this is the first step on the way to obtaining solar energy from space for its application on Earth.

But meanwhile, we are talking about the successful transfer of only 1.8 kilowatts of energy (just right to start an electric kettle) by means of microwaves and an accurate transmitter.

The developers note that to use as a power source the cosmic energy of the Sun, in comparison with solar energy from the Earth’s atmosphere, is very advantageous: it is always available in the right amount, regardless of weather conditions and time of day.

Space solar energy has long been successfully used on the ISS . But the idea of ​​delivering this inexhaustible energy from outer space to our planet for a long time was perceived as something from the category of science fiction.

Capturing the energy of the Sun

The Japanese expect to receive star energy via microwave satellites-transmitters, remote from the Earth for 36,000 km and equipped with panels and antennas to collect solar energy. However, in theory everything is simpler than in practice. The introduction of technology into reality, perhaps, will require decades, 30 years, or even more. In the meantime, you need to figure out how to send such massive structures into space, how to mount them and maintain them in working order.

Developments in this direction were conducted by American researchers in the 1960s, and the Japanese Ministry of Industry began sponsoring local developments since 2009. First of all, the Japanese are concerned about the problem of the shortage of energy resources in their country, because the import of fuel to Japan reaches huge volumes, especially since the use of nuclear energy after the disaster in Fukushima in 2011 ceased .
