Since then, several studies have been carried out by NASA, Boeing and Mitsubishi. Its promise: access to almost unlimited energy, making it possible to put an end to fossil fuels.

The concept is experiencing renewed interest, because it would be an effective way to fight global warming and reduce polluting emissions while securing access to clean energy across the planet. Better still, the conditions are now met. “ The technology of converting solar radiation into electricity and then into radio frequency signals sent to Earth works. It is used by telecom satellites…
