You can save on energy and never run out of power for your mp3 player or cell phone. This portable solar panel can be used to power small electronic devices, so anywhere there's sun is a place to recharge. If that's not a great excuse to stay at the beach another hour, I don't know what is.

And if you don't want to spring for the mini solar panel, just use a bottle of gatorade and an onion. Don't believe me? Check out this YouTube video.
