A unique system that can produce Hydrogen inside a car using common metals such as Magnesium and Aluminum was developed by an Israeli company.
The system solves all of the obstacles associated with the manufacturing, transporting and storing of hydrogen to be used in cars.
When it becomes commercial in a few years time, the system will be incorporated into cars that will cost about the same as existing conventional cars to run, and will be completely emission free.

SUMMARY OF THE INVENTION . According to the invention a method of generating hydrogen comprises the steps of exposing a fresh metal surface to water and heating the interface between the metal surface and the water at least to the lowest temperature at which the metal reacts with water to form a metal oxide and hydrogen, the metal being chosen from metals which are higher in the electromotive series than hydrogen and having stable and safe handling characteristics. Preferably the metal surface is exposed and the interface heated by pressing an electrode of the relevant metal against a second electrode under water and applying a high voltage between the electrodes while preferably moving the electrode surfaces relatively to one another.
Refuelling the car based on this technology will also be remarkably simple. The vehicle will contain a mechanism for rolling the metal wire into a coil during the process of fuelling and the spent metal oxide, which was produced in the previous phase, will be collected from the car by vacuum suction.
The only minor drawback, which also limits the choice of possible metal fuel sources, is the weight of the coil. In order for the Hydrogen car to be able to travel as far as a conventional car it needs a metal coil three-times heavier than an equivalent petrol tank. Although this sound like a lot in most cars this will add up to about 100kg (220 pounds) and should not affect the performance of the car.
