Designer Sayalee Kaluskar has a new concept that will make sunglasses better than just being used to protect you against the sun. Adding a thin solar cell to each arm, the glasses become a subtle way to top off your gadgets when you're out and about.

The solar power collection arms on the Ray-Ban Shama Shades can be removed to reveal a microUSB or Lightning connectors to transfer all that juice collected to your devices. [Sayalee Kaluskar via Taxi]
