I hate this keyboard. It is a new lap top and the keyboard sucks.
Back to the subject (third try). This is a low power demonstration. A real system would take a larger current source. Low voltage, high current. The advantage is that it can be run from a low voltage source, such as a solar cell.
That means that low-voltage electricity can be used successfully to generate Hydrogen and Oxygen. It is possible that a vehicle could be made that generates electricity while its wheels are turning, which could then be used to split water, the end product of burning Hydrogen and Oxygen. You could have almost limitless power on a cup of water if the exhaust water was recycled inside the engine. Next to no emissions, too. All you'd have to worry about is the water freezing if it's in a cold climate. Maybe some antifreeze would do to keep that from happening. This has a great potential to change the way we drive.
