Is Wireless Power Finally Here?
PowerCast demonstrated wireless power at this year’s CES, showing how up to a watt of energy can be “broadcast” and received by various devices. While this isn’t an entirely new concept, this company seems to be best positioned to do something useful with it. This is nothing like the induction charging you may have seen on razors and toothbrushes. PowerCast’s technology harnesses energy from an RF field. Their initial research is focused on delivering consumer and military applications. The first consumer application could be trickle-charge solutions for portable devices: lay your phone or personal media player on your desk or hotel night-stand, for example, and it would start charging automatically!
