Solar Arcadia (http://www.solararcadia.com) has released the Solar
Charger for Apple iPhones. It harnasses power from the sun to charge
both first generation and 3G iPhones. The US$45.95 charger is
designed with a reclaimed sheepskin phone cover and a built-in solar
charger.
To charge, users attach the iPhone to the charging case, find some
sun, and go. The Solar Chargers can even derive power from artificial
light. The charger utilizes state-of-the-art solar technology that
enables users to charge their iPhones while walking, biking, or even
hiking without ever having to plug them into electrical outlets.
