Apple to work with sun - files patent to use solar power for handsets

iSun adapters for iPhone

It was only a matter of time before Apple formed an alliance with the sun

Apple has filed a patent application which suggests that it's looking to build solar charging technology into future devices.

This is not a new idea, writes Adamson Rust in TechEye.net.

The surface area is very important for solar cells, and much depends on the efficiency of management your device achieves.

But with power management constantly improving, we are approaching the point at which the sun could just about provide enough juice to power a handset. One day.

The patent was filed in 2008 and the description suggests powering portable electronic devices using multiple solar cells - linked to the device, so the device can power up again.
