The Japanese have invented a car that runs on nothing but water. (See Reuters News Report, etc). It extracts hydrogen from water to propel the car. It will run for about an hour at 55 mph (80 km) per hour on only one liter of water. A very simply action that everyone can take, is to promote such technology as this where ever they can. Imagine every vehicle in the world running on nothing but water. We certainly have enough of that on this planet. And that would have an immediate effect on our environment for certain.
