Inductive

The Power Mole wirelessly transmits 10 watts of electricity through window glass, allowing indoor outlets to power outdoor devices. It's built on the inductive coupling technology utilized in wireless smartphone charging systems.

​Given that the battery life of most multicopter drones typically doesn't exceed 30 minutes of flight time per charge, there are many tasks that they simply can't perform. That's why scientists are developing an alternative – they're wirelessly transferring power to a drone as it's flying.

The Apple Watch may not be in stores just yet, but that isn't stopping various companies from designing accessories for it. We spotted one such product at CES this week – Standzout's aluminum-bodied Bandstand inductive charging stand.

To overcome the frustrating morning surprise of forgetting to plug in an electric car, BMW Group is developing a new generation of wireless inductive charger technology that’s comparable in speed to cables, but requires no more effort than parking and pressing a button.

Researchers at the Korea Advanced Institute of Science and Technology (KAIST), have developed a wireless charging system that can charge around 40 smart phones at a time, from a distance of 5 meters (16 ft).
