Scott Ertz interviews Arun Kumar, partner presenter at the Wireless Power Consortium booth.

They discuss the current state of wireless charging technology. They demonstrate a 15 watt wireless charger hooked to a laptop. It will soon be possible to integrate wireless charging circuitry directly into laptop computers for the first time, perhaps within a year.

Scott also interviews John Perzow, vice president of market development, about longer-distance charging. John demonstrates that it is now possible to charge a Qi device up to an inch away through an inch thick block of wood. Distance charging is problematic since electrical charging efficiency drops off very quickly with distance.
