Apple is reportedly looking into solar panels as a power source for mobile devices. A recently published patent application discovered by the Apple enthusiast site MacRumors.com describes a technique in which solar panels would be built behind a portable device’s LCD screen. From that location, the panels could absorb ambient light that passes through.
The technique would eliminate the need for Apple to redesign its iPods and laptops to make room for the new technology. Among the problems with using solar panels on devices are durability and the need to take up valuable space on the compact devices.
Apple isn’t the first to consider this technique for using solar power. Motorola describes a similar approach in a 2001 patent.

Apple and technology companies routinely apply for patents on technology that may never find its way into products.
