Power transmission without wires

Japan has successfully tested wireless power transmission technology, an important step that opens up the ability to produce electricity from outer space using solar energy and transmit it to Earth, according to RT news agency.

Japanese scientists boiled a kettle by using 1.8 kW of microwave power through the air to a receiver about 55 m away, RT reported on 12.3.

Although only a sufficient amount of electric water has been boiled and the small distance is successful, this success has also made a big jump. It could open up the possibility of generating electricity from solar energy infinitely out of space and transmitting to Earth , a spokesman for the Japan Space Exploration Agency (JAXA) told AFP.

The idea of ​​a satellite about 36,000 kilometers from the ground with solar-absorbing panels and generating electricity to transmit to Earth using microwaves can be done with this research. However, we can take decades to see this technology applied in practice, be it in the 2040s or later, JAXA spokesman added.

Japanese scientists have to solve a lot of challenges to turn this idea into reality, such as how to put systems with large structures into space and how to build and maintain their operations. it, according to AFP.

The production of solar electricity on space has many advantages over ground production, especially the power source to generate electricity at all times and is not affected by weather or time .

It is known that Japan's research project on outer solar power system (SSPS) started in 2009 funded by the government of this country.

The idea of ​​space-based solar power was first introduced by Dr. Peter Glaser in 1968 in the United States and he was granted a patent in 1973. The project was funded by the Aeronautics and Space Agency. US (NASA) and US Department of Energy sponsored. However, it ended in the 1980s because it was too expensive, according to RT.
