Obviously it’s an eco-friendly gadget exploiting solar energy. It’s called Solar Pebble, a solar powered lamp designed by Adam Robinson for Plus Minus Solar.
Solar Pebble comes with a efficient solar panel, which can turn solar energy into electricity and storage in the batteries of the lamp. And moreover, the solar lamp can also charge other gadgets such as iPhone or MP3 player. The U-shaped handle allows you to easily carry the solar lamp.
Unfortunately, Solar Pebble is still a prototype. We have no any information about the release.
