Electronics such as phones and laptops may start shedding their power cords within a year.
That's the prediction of Eric Giler, CEO of WiTricity, a company that's able to power light bulbs using wireless electricity that travels several feet from a power socket.
WiTricity's version of wireless electricity -- which converts power into a magnetic field and sends it sailing through the air at a particular frequency -- still needs to be refined a bit, he said, but should be commercially available soon.
Giler, whose company is a spinoff of a Massachusetts Institute of Technology research group, says wireless electricity has the potential to cut the need for power cords and throw-away batteries.
"Five years from now, this will seem completely normal," he said.
One set of researchers is able to send power over long distances but in very small amounts
