Japan will try to extract solar energy from space in 2025

Japan’s aerospace research agency JAXA will try to transmit solar energy from space as early as 2025. This is reported by Engadget.

The project envisages the deployment of a series of small satellites in orbit, which will then try to direct the collected solar energy to ground receiving stations located hundreds of kilometers away.

In 2015, Japan made a breakthrough when JAXA scientists successfully transmitted 1.8 kilowatts of energy, enough to power an electric kettle, over a distance of more than 50 meters to a wireless receiver. Now the country is ready to make this technology one step closer to reality.

It was first proposed to use orbital solar panels and microwaves to transmit energy to Earth in 1968. Since then, several countries, including China and the USA, have spent time and money on the implementation of this idea.

The technology is attractive because orbital solar panels represent a potentially unlimited renewable energy. In space, solar panels can collect energy regardless of the time of day, and thanks to the use of microwaves to transmit the energy they produce, clouds are also not a concern.

However, even if Japan were to successfully deploy an array of orbiting solar arrays, the technology would still be closer to science fiction than reality, because producing an array that can generate 1 gigawatt of electricity — or about the power of one nuclear reactor — would cost roughly $7 billion a year. currently available technologies.
