Tesla’s Dream is Getting Closer: Japanese Scientists Transmit Electricity Wirelessly Through the Air

Researchers from the Japan Aerospace Exploration Agency (JAXA) managed to transfer 1.8 kilowatts of power via microwaves to a specific receiver located at a distance of 170 feet (55 meters). You may think that it’s not such an impressive distance, and the delivered energy was only enough to power an electric kettle, but the experiment opens up new prospects for alternative energy research. In particular, similar technology could be utilized for collecting solar energy in space and delivering it to Earth. In fact, this is how the International Space Station is powered – it converts sunlight into electric current with the help of solar cells placed on its solar array wings.
