SolSol's baseball hat can charge your phone using solar power
Solar technology is still far from becoming ordinary, but we're seeing more and more of it make its way to consumer products. And now that includes hats. SolSol, a startup from Los Angeles, made a baseball cap that has a small solar panel built into its brim. You can use it to charge your smartphone, tablet or any other device that needs to be plugged in via USB. It looks kind of odd to have a cable hanging down from your head, but the hat could come in handy if your gadget's battery is running low and there are no other outlets nearby.
