Solar backpacks made from plastic bottles

We've seen solar bags ... and we've seen bags made of plastic bottles ... but this is the first time we've seen those two environmental innovations co-existing.

Pretty frikkin cool really. Voltaic and Reware are both making gadget-charging solar bags out of post-consumer plastic.

Post-consumer, recycled-plastic fibers take less energy to create, don't use any new materials, and keep the plastic in use and out of landfills. Meanwhile, solar-powered bags keep your cell phone or iPod going without the need to plug in to the electric grid.

In terms of environmental innovations, it's not gonna change the world -- but it is a pretty cool way to wear your EcoGeek badge on your sleeve.
