The Walt Disney Company has built a room that it says can wirelessly power and charge any devices inside it. Wireless charging usually only works when a device is touching a power source. But researchers say they have found a way to provide wireless power and charging capability to large areas. A scientific team from Disney Research recently demonstrated the technology. Alanson Sample is the lead researcher at Disney Research. He explained the goal of the project in a video. “What we really want is a three-dimensional charging experience where you walk into your living room or office and your cellphone is charged simply by walking in.” Sample said the idea of wireless power goes way back to the turn of the 1900s. This is when famous scientific inventor Nikola Tesla proposed a method to send wireless power all over the world. His plan, which involved a giant tower built in New York, was not a success. But the Disney team said it was inspired by Telsa’s early efforts to develop a new system for wireless electricity. The process uses magnetic fields to send power to specially designed receivers.
