The vehicle in the above picture is the i-H2GO by Horizon Fuel Cell Technologies and Corgi International. It is a remote-controlled car which is powered by a hydrogen fuel cell… meaning it is indirectly powered by water.
Simply pour some water into the storage tank and the water is split via electrolysis into hydrogen and oxygen using electricity generated either by a solar panel or using a USB charging cable in situations where this is little or no sunlight. To control the car, you can use your iOS device to power the car and an Android app is said to be in the works. This is in contrast to the older H2Go which utilized a conventional radio controller.
Purchasing one of these bad boys will set you back $180. See the video below for a demo of the fuel cell powered RC car.
