The world doesn’t switch off, and more than ever we need innovative solutions for sustainable energy.
Can the sun’s energy be used to generate electricity 24 hours a day, on a global scale?
The answer is yes, using solar cells from space permanently inclined towards it. If coated with an ultra-light and strongly reflective membrane, thousands of satellites in space could be combined to form an enormous power station.
Solar energy, converted to waves, would be sent to antennas on earth using electromagnetic fields. Many international researchers are working on such concepts, while the European Space Agency is currently also assessing new ideas.
Perhaps in the future it won’t be green men, but green electricity appearing from outer space…
