A fresh patent from Google suggests that future Chromebooks may one day charge wirelessly and even power up smaller devices.

Specifically, Google wants to pack your laptop’s keyboard with small charging coils that could act as both receivers and transmitters. That means you could potentially juice up your smartphone by simply setting it down on top of your keyboard. The coil itself is small enough to sit under a single key, so repairs would be relatively easy if it suddenly stopped working.

Google notes that the technology could exist in a standalone keyboard, though it can also be built into a larger laptop. Of course, there’s no guarantee we’ll see any of this implemented in the near future if at all. Then again, it could be a perfect feature for the Chromebook Pixel lineup, which Google uses to showcase the best of its Chrome OS operating system.
