CNET reports on a new method of generating power that was displayed at the recent Consumer Electronics Show. RCA demonstrated a small battery pack that can convert energy transmitted in Wi-Fi signals into DC power.

They explain:

The device, called the Airnergy, uses an antenna and circuitry to harvest the energy and an internal battery to store the electrical charge. A company representative told OhGizmo that they were able to charge a BlackBerry from 30 percent to full charge in about 90 minutes using the ambient Wi-Fi signal at CES, although the charge time varies depending on how close the battery is to the original signal.
