Carrying Bags for Eco-Conscious Gadget Freaks

Here's a way for the on-to-go gadget freak to stay powered up: As part of their line of green products, Office Depot is offering the Voltaic series of bags. Like the Voltaic Converter pictured here, the knapsacks and messenger bags (with prices ranging from $179 to $219) sport waterproof solar panels that generate up to 4 watts of power for whatever gadgets you happen to be toting around. There's also a lithium-ion battery pack for storing any extra juice, so you can charge your devices even on cloudy days. If you're looking for a little extra eco-karma, the bags are largely made of recycled soda bottles.

Passers-by might do a double take when they notice the shiny panels on the bags, but don't let it concern you -- you're walking away from them, anyway.
