PowerPockets portable solar chargers
These portable solar chargers may be a bit on the pricey side ($150 for the 6.5-volt model, $275 for the 12-volt), but it looks like that's the price ya gotta pay to be an evironmentally conscious geek. Both PowerPocket models will fold up to stash away in your bag and come with full array of adapters to accomodate most any electronic device you've plunked down on. Apparently the 6.5-volt model will charge most devices—like PDAs, MP3 players and digital cameras—in 2-4 hours, with the 12 volt PowerPocket cuts that down to 1-3.
