When you need to charge your electronic devices on the go, it can be a hassle trying to find somewhere to plug in. And though some devices can already be charged without wires, researchers at The Walt Disney Company have recently supersized the technology by building a wireless “charging room.”
Scientists at a branch of The Walt Disney Company called Disney Research have converted an entire room into a wireless charger that can boost the batteries of 10 objects at one time, according to the study. The researchers said they were inspired by inventor Nikola Tesla, who created the first system to wirelessly transmit electricity — the Tesla coil.
Tesla believed there could be a global network of wireless electricity that would use an electromagnetic wave that reverberated between the ionosphere (a layer of the Earth’s atmosphere filled with ions and free electrons) and the ground, study co-author Alanson Sample, an associate lab director and principal research scientist at Disney Research, explained in a video. While Tesla’s vision didn’t come to fruition, Sample and his colleagues were inspired to investigate how wireless charging could be set up in large spaces.
