PowerBeam steps closer to launch of wireless electricity

Grier Graham, vice president of product development, said the company can use a laser to generate about 1.5 watts of power to a solar cell as far away as 10 meters.

Thats enough to power an electronic speaker or small low-wattage light-emitting diode (LED) lights. It can also charge the battery in a digital picture frame.
