Japan conducts successful experiment on wireless power transmission for space project

    Mitsubishi Heavy Industries engineers conducted a successful experiment on wireless energy transfer at an industrial level. One of the customers of the work is Japan Space Systems, which is engaged in the implementation of a scientific project on the transfer of solar energy. The program is sponsored by the Japanese Minister of Economics and is called Space solar power systems (SSPS). According to the project, the end result should be the appearance of special satellites in near-Earth orbit, which will be actually solar panels and simultaneously transmitters of energy to the Earth.

    The experiment so far had a purely “earthly” character both in the place of the conduct and in the distance over which the energy was transmitted. Engineers installed a transmitter and a power receiver at a distance of 500 meters between them:

    The transmission power was 10 kW and was transmitted in the form of microwave radiation. The LED indicator installed on the receiver signaled to the engineers that the transmission was successful. Aft of the very fact of transmission, a special orientation system of the energy beam in space was checked so as not to scatter it into space without any benefit.

    The SPSS program - with the aim of which the experiment was carried out - implies that energy will be transmitted from the geostationary orbit of the Earth in the form of microwave or laser radiation. Its receiver will be special stations that they plan to build on an artificial island in Tokyo Bay. Similar projects were planned by American scientists in the 60s of the last century, but they were in serious development only in 2009.
