I like this new solar charger, the P-Flip™ Foldable Solar Power from Denix. It’s foldable, rechargeable and generates up to 8 hours talk time, 15 hours of video or gaming, and 60 hours of music. The design makes it easy as to use as a desktop holder. Costs $79.90 USD. Via PicoCool
Prius has some solar wi-fi benches setup in Yerba Buena Gardens. Would love to see SF have permanent free solar powered wi-fi stations.
