Cordless extension cords? Powerbeam has it covered. Right now, Powerbeam is perfecting a wireless, laser-based power transfer system that can act as an extension cord to power devices using a line-of-sight system that will send power as far as you need it to go. The lasers are about the size of pepper flakes, and will transfer tens of watts of power, and in the future could transfer more. Check the video for the full scoop on what looks to be a pretty cool solution for transferring power wirelessly.
