Japan emission of solar energy from space

Japan and JAXA, the country's space agency, have spent decades trying to make it possible to emit solar energy from space.

Το 2015, η Ιαπωνία έκανε μια σημαντική ανακάλυψη όταν οι επιστήμονες της JAXA απέδωσαν με επιτυχία 1,8 κιλοβάτ ισχύος, αρκετή ενέργεια για να τροφοδοτήσουν έναν ηλεκτρικό βραστήρα, περισσότερα από 50 μέτρα με έναν ασύρματο δέκτη. Τώρα, η χώρα φαίνεται να είναι έτοιμη να πάει την one step closer to reality.energy from space

The Nikkei he says that a Japanese public-private partnership will attempt to beam solar power from space in 2025.

The project, led by Naoki Shinohara, a professor at Kyoto University who has been working on space solar energy since 2009, will attempt to send a series of small satellites into orbit. They will then attempt to transmit the solar energy collected by the arrays to ground receiving stations hundreds of miles away.

The use of orbiting solar panels and microwaves to send energy to Earth was first proposed in 1968.

Since then, some countries, including China and the US, have spent a lot of time and money to implement the idea.

The technology is attractive because orbital solar arrays represent a potentially limitless supply of renewable energy. In space, solar panels can collect energy regardless of the time of day, and by using microwaves to emit the energy they generate, clouds are not a concern.

However, even if Japan develops and manages to send a fleet of orbital solar arrays, the technology will still be closer to science fiction than reality.

Why; Building an array capable of producing 1 gigawatt of power – or about the power of a nuclear reactor – would cost about $7 billion with available technologies.
