Another hydrogen car concept

Yet another idea in the ever growing concepts for alternative fuels for cars; well in this case, another way to produce that fuel:

The Car That Makes Its Own Fuel

From the article:

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.

You may be thinking that if it costs the same as existing conventional cars to run, why bother? Firstly, oil prices are only going to be getting higher, so this would be considered reasonable, but mainly what you should be thinking of is a sustainable future. Being an engineering student, I have come to realise how important it is to think of a sustainable future and with ideas like this, it looks like engineers of today are heading in the right direction.
