an employee of MiniWiz shows off a wind and solar charger for your cellphone. You can plug the solar panel into your cellphone and charge it in a bright place. With the wind charger, you can hook it up to the handle-bars of your bike or hang it out the window of your car to capture the breeze, which then powers your cellphone's battery. It comes with a manual crank you can use as a charger, in case you're in a dark, windless environment.
