Flexible thin-film solar panels have been quickly making their way onto everyday garb in recent years, adding on-the-go charging systems for cellphones, iPods, PDAs, cameras and gaming devices to your wearables. Here's a quick roundup of the hottest planet-positive gizmos: Voltaic Systems [1] has a super-snazzy solar backpack and messenger bag [2] with battery storage capacity that allows it to function as a power reservoir even at night or on a cloudy day. Silver, orange or green panels add a dash of style.

A team of Iowa State University [3] students recently invented a surprisingly chic solar-powered handbag [4] (eat your heart out Prada!) and rice paddy hat [5] for portable PV charging on the town or in the field. A cowboy-style solar hat is also in the works. The products will be available to consumers this year, according to the Discovery Channel [6].

And Solar Style [7] now offers both portable solar chargers that you can pop in a briefcase, plus a combo solar-powered radio/flashlight/charger. They convert both artificial light and sunlight into usable electricity.

Finally, coming soon from SCOTTeVEST [8]: a jacket for the likes of Buck Rodgers [9]. A bank of multicolored solar panels on the back of the jacket connects to a power source in the pockets where you can plug in your hand-held devices.
