Japanese Scientists Have Successfully Transmitted Electricity Wirelessly Through The Air

Scientists in Japan have successfully transmitted electricity wirelessly through the air, validating much of the work Nikola Tesla did while he was alive. Debate has raged for decades about whether it could be done, and scientists with the Japan Aerospace Exploration Agency have done it. They used microwaves to deliver electricity to a target 55 meters away.

“This was the first time anyone has managed to send a high output of nearly two kilowatts of electric power via microwaves to a small target, using a delicate directivity control device,” a spokesman for the agency told AFP on Thursday.

“SSPS consists of a space-based power generation/transmission facility that gathers sunlight, converts it into microwaves or laser beams, and transmits those to the ground; and a power receiving facility on the ground,” explained researcher Yasuyuki Fukumuro.

“There are many technological challenges to solve before SSPS can be implemented. When transmitting power by microwaves, a significant technological challenge is how to control the direction, and transmit it with pinpoint accuracy from a geostationary orbit to a receiving site on the ground,” he added.
