Japan Will Send Space-Based Solar Energy To Earth By 2025

JAKARTA - Japan is back with its new ambitions that will try to radiate solar energy from space to Earth. This plan will be implemented as early as 2025.

This time, the public and private partnership project was led by a professor at Kyoto University, Japan, Naoki Shinohara, who has been working on space-based solar energy since 2009.

In this latest mission, Shinohara will try to deploy a series of small satellites in orbit, which can later emit solar energy and then be collected by arrays to ground-based receiving stations, hundreds of miles away.

The country, together with the Japan Space Explorer Agency (JAXA), has spent a long time trying to develop a way of emitting solar energy from space.

Almost a decade ago, this Sakura Country has made progress by being able to reduce 1.8 kilowatts of energy. Although reportedly not as high as planned for the project, that energy is enough to turn on the electric cassava.

The distance is about more than 50 meters from wireless receivers, making the electric cassier more striking. Now, Japan plans to take technology one step ahead by doubling it on Shinohara's new project.

In fact, using orbital solar panels and microwaves to transmit energy to Earth was first proposed in 1968.

At that time several countries, including China and the US, had spent time and money pursuing the idea. This is because the orbital solar array represents an unbounded supply of renewable energy.

In outer space, solar panels can collect energy at any time, and by using microwaves to emit the power they produce.

If Japan manages to deploy a set of orbital solar arrays, of course it will cost a lot of money. The Pasa, launching Engadget, Monday, May 29, produces an array that can generate 1 gigawatt power or around the output of one nuclear reactor, will cost about US$7 billion (Rp104.7 trillion) with current technology.
