Japanese scientists from the Japan Aerospace Exploration Agency have announced that they have been successful in transmitting energy wirelessly and with high accuracy, being able to microwave 1.8 kilowatts (just enough to heat a kettle) over a distance of 55 meters.
“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 spokesperson for JAXA stated.
Before getting too excited, there is still a long way to go from here. The scientists’ ultimate goal is to set up solar satellites around 36,000 km of Earth’s surface in order to harness the Sun’s power and beam it back to the Earth’s surface via antennae. This means that, if proven successful, we could be looking at an unlimited energy solution. However, there is still a matter of taking everything from the planning stage to the actual application phase… and that takes time.
“But it could take decades before we see practical application of the technology – maybe in the 2040s or later,” the spokesperson stated. “There are a number of challenges to overcome, such as how to send huge structures into space, how to construct them and how to maintain them.”
Even so, given that the experiment will eventually take place and be successful, we are looking at one of the most important technological breakthroughs in human history.
