Looks like there are going to be greener ways to charge up AA and AAA batteries, and it's not just a conept. Energizer is going to debut a solar powered battery charger at the upcoming Consumer Electronics Show.
The device:
- will feature a USB-out port to power other devices (since some cellphones, cameras, and GPS units have USB plugs, like most iPods forexample);
- can be charged from an AC wall outlet in addition to the sun;
- and is weatherproof to withstand the elements.
