A revolutionary recipe to cook hydrogen has been elaborated by European scientists, and this might be used to drive our future hydrogen cars according to IsraCast. Take some common metal such as zinc oxide (ZnO). Put it under a heat source generated by solar energy. Don't forget to concentrate the solar rays by special mirrors to obtain a temperature of 1200°. Add a teaspoon of carbon in the form of coal. Wait until you get some pure zinc powder. Mix this powder with some water. And here is the result: pure hydrogen with almost no fossil fuels burnt! This clever recipe might be used to produce the hydrogen needed by your next car in about ten years. But this technology could also be used to produce non-toxic and non-flammable zinc-air batteries.
