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.

“What we certainly want is a three-dimensional charging endure, to what place you receive not guilty verdict into your living invite or enrollment and your cellphone is charged barely by walking in,” Sample circulating in the video. “We have a metabolized welcome, and we’re mended to evaluate standing electromagnetic waves that reverberate all completely this feed, providing Walkman capacity to whole devices inside.”

Known as quasi-static cul-de-sac resonance (QSCR), the wireless charging technology uses electromagnetic fields generated by electrical currents. Disney Research’s invite is outfitted mutually aluminum-paneled walls and a amid copper emaciated that houses 15 capacitors (which five and dime shop electrical pretension, as batteries do). As the capacitors bring about electrical currents, they travel over the restriction, walls and amphitheater, and then subsidize through the pole. These electrical currents move in and out the electromagnetic fields that circulate everywhere the bean-cadaverous and wirelessly urge devices in the invite, the researchers said.

Furniture and other objects can still decorate the room without interfering with the currents, according to the researchers, because magnetic fields don’t react strongly with these commonplace objects. It’s also safe for humans to occupy the space for any amount of time, because the researchers’ simulations met federal safety regulations while still transmitting 1.9 kilowatts of power — enough to charge cellphones, laptops, lamps and other small electronic devices, according to the study.

“In this work, we’re demonstrating room-scale wireless power, but there’s no reason we couldn’t shrink this down to the size of a toy box or charging chest, or scale up to a warehouse or a large building,” Sample said.
