• Researchers used microwaves to deliver 1.8 kilowatts of power—enough to run an electric kettle—through the air with pinpoint accuracy to a receiver 55 metres (170 feet) 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.
  • The idea would be for microwave-transmitting solar satellites—which would have sunlight-gathering panels and antennae—to be set up about 36,000 kilometres (22,300 miles) from the earth.
