Before the Sun finally explodes and expands and takes our solar system with it, Japan and its JAXA space agency want to find a way to extract energy from the Sun and use it here on Earth.
Japan aims to be the first country in the world to send solar power from space to Earth for large-scale power generation.
According to local reports, the first satellite transmitters will be built by 2025 through a public-private partnership led by the Japanese space agency JAXA.

Touching the sun power in space for use on The earth will get closer reality if researchers in Japan is doing well in broadcast power from outer space to the ground using microwaves.

The project, led by Naoki Shinohara, a professor at Nikki Kyoto University who has been working on the solar energy program since 2009, aims to have a series of small satellites in orbit convert solar energy into microwaves and send it to ground receiving stations. which then convert it into electrical energy.
The concept, first theorized in 1968, has a number of advantages over ground-based solar installations, notably the ability to harvest solar power over a longer period of time not constrained by the typical solar cycle.
These microwaves will be able to pass through the clouds, so the technology is able to work in adverse weather conditions.
Japan has already taken many first steps in this field, first transmitting energy via microwaves into space in the 1980s.
And in 2015, JAXA scientists made another breakthrough when 1.8 kilowatts of power was sent to a ground receiver, about enough to power an electric kettle.
Many other countries and regions are also working on this technology, and the European Space Agency last year unveiled a plan to test the feasibility of using solar energy in space.
More research needs to be done before this is widely possible, although recent advances in high-efficiency solar cells, wireless power transmission, and in-orbit automated power harvesting mean that China and the United States are also working on ways to harness solar power from solar power. energy outer space.
Among the concerns associated with this technology is the impact of low-power microwaves on the health of humans, animals and plants.
