In this video from RoboBusiness 2008, we interview Steven from Powercast who shows off some cool wireless power technology.
From the Powercast website:
Founded in 2003, Powercast developed a receiver module with breakthrough efficiency levels. Coupled with a transmitter that sends RF energy using algorithms developed by Powercast, the Powercast Wireless Power Platform™ was born. While the concept of sending power “through the air” has been discussed for more than 100 years, Powercast is the first company to make it commercially viable. Powercast is now leading the cross-industry initiative to bring wireless power to a hundreds of low power devices.
