This wearable solar charger/watch is currently on Kickstarter trying to become a reality. Created by Sean Ebersold, of EnergyBionics, for those times when your phone battery needs a boost. The design of the Carbon Wearable Solar Charger + Watch looks a bit clunky. Not sure how that can change much with todays battery technology.
The Carbon Solar Watch will give you an extra 3 hours of talk time or web browsing (assuming you have an iPhone 4S or equivalent). Video of the Carbon Solar Charger Watch after the break.
