Sony Prototype Sends Electricity Through the Air
Despite the numerous technologies that exist for sending data through the air there’s one cable that most gadgets can’t do without at some time. The power cable remains a necessary but sometimes unsightly part of many modern electronic appliances — but now even that might be on the way out.
Sony has developed a prototype power system that can send enough electricity to power a television set wirelessly over a short distance, it said Friday. In tests the company succeeded in sending a conventional 100 volt electricity supply over a distance of 50 centimeters to power a 22-inch LCD television.
