The smart phone of the future will be self powering

In a nutshell, the technology involves alternating strips of solar cells overlaid with a lenticular surface; it's not unlike what you find on some glasses-free 3D displays to beam different images to the left and right eyes, except you're beaming sunlight to solar cells and routing the human eye through to the display below. Because the film is applied directly to the screen -- which would lie below the capacitive layer -- there's no effect on touch performance. Clearly, there's some magic involved in making that happen without being optically annoying, and Wysips says they've perfected it over three generations of prototypes.

This is actually pretty neat. 1.2-25v is a long way from fully powering touch slates, but it'd make a nice extension to the battery life.

too bad the majority of people put their phones in their pockets and have the screen up to their ear when talking.

but even on the back would be nice? say im at the office and i put my phone down and put it on the solar side up. granted internal light is NOT anything significant, but if you charged an hour, you might get that 10-20% extra juice you need to play Angry Birds on your subway ride home.
