Here's how it works: a thin charging station takes electricity and converts it into sounds, which are then transmitted over ultrasound. A receiver stuck to a phone or any other device then catches those sound waves and converts them back into energy. It does have limitations, though, such as not being able to pass through walls like WiFi, so you'll have to buy several transmitters if you want to be able to charge wirelessly in every room. Despite that, Perry has huge faith in her brainchild and believes that it has the potential to become as ubiquitous as WiFi. She even believes that it could influence the way manufacturers design their devices, leading to smaller batteries, since phones with uBeam receivers will constantly be charging anyway.

The company founder didn't say when the first consumer devices will come out, but she promised to sell directly to consumers and to businesses when the time comes.
