SolarFocus' Kindle Cover
OLPC wasn’t the only CES-goer to show off a solar-powered device. SolarFocus, a tech organization that has dedicated itself to the pursuit of solar energy, unveiled its SolarKindle Lighted Cover for Amazon’s Kindle e-book tablet.
As its name suggests, the SolarKindle Lighted Cover acts as a solar panel that conserves a Kindle’s power. When placed over the device, the cover uses sunlight to fuel its own built-in reserve battery rather than the Kindle’s own battery, allowing it to conserve overall battery life.
Despite the additional functionality, SolarKindle said the cover is still a hit aesthetically, designed to "look smart and feel great" without being bulky.
