Japan has been trying for decades to make it possible to transmit solar energy from space to Earth. In 2015, the country made a breakthrough when scientists managed to transmit 1.8 kilowatts of power, enough energy to power an electric kettle. Today, Japan is on the verge of bringing this technology closer to reality. Indeed, a project will attempt to deploy a series of small satellites in orbit, from which the solar energy collected by the solar panels will then be transmitted to reception stations on the ground.
