Water is poured into the i-H2GO car’s refueling station, then it is electrolyzed. The process splits H2O into hydrogen and oxygen using the power of a solar panel. The hydrogen is then directed into the car, and the car basically runs off hydrogen by converting it into electricity. On cloudy days, you can use a USB cable to electrolyze the water.
The i-H2GO is controlled by an iOS app at the moment. An Android app is forthcoming.
