Last night, I saw Disney Pixar's new animated movie, WALL-E. To my surprise, the little robot was being powered by solar energy.
Every morning, he'd stand under the sun, pull out his solar panels, and begin charging up. If you look at the photo above, you'll see a yellow meter on his chest. This gauge lets him know when he's fully charged.
Pretty cool, right?
The bottom line is...
Be more like WALL-E.
