What if you could wirelessly recharge all your gadgets by simply being in your bedroom. That dread of a dead iPhone would be a thing of that past. This theoretical wonder creation is not longer so theoretical as Disney Research has created an electricity room that can provide free-roaming wireless electricity to any number of devices.
Detailed in PLOS One, the Pittsburgh-based research team funnels 1900 watts of energy into a room with an efficiency between 40 to 95 percent. Crucial to their efforts is the room itself, which was purpose-built for this experiment (your bedroom will have to wait). Although Disney has not developed a machine that will free you from chargers they have completely done away with the need for sockets.
The electricity room itself is pretty simple, but on the less visible side of the spectrum, the walls are all made of aluminium panels.
As for that very visible copper pole in the middle of the electricity room, a part of it has been removed and 15 capacitors installed. Chosen for its “ease of construction,” the researchers say in their paper, the pole controls the resonant frequency and isolates electric fields that are being fed into the room from a signal generator at 1.32 MHz.
While the researchers suggest cabinets, rooms, and warehouses” as potential uses, it’s hard to imagine Disney isn’t dreaming up bigger plans. It’s easy to imagine such a room playing a role in a theme park adventure. Maybe the Haunted Mansion can leave you scared, and your iPhone fully charged.
