Apple was recently granted 16 new patents, including one for a solar photovoltaic power source for mobile electronics, which Apple envisions operating in “remote locations.” This follows Apple’s January patent on a solar power source for mobile devices.
August 24, 2011 — Apple was granted 16 new patents, including one for a solar photovoltaic power source for mobile electronics, which Apple envisions operating in “remote locations.”
The patent, no. 8,004,113, covers solar-power control electronics, such as a voltage converter attached to a solar power source and a controller that supplies this power to the portable electronic device. The solar “tracking” technology would ensure a steady supply of electricity for the electronic device, despite solar’s intermittent nature.
The patent was filed in 2006 by Wendell B. Sander, Daniel A. Warren, and Aaron Leiba of Apple Inc.
