The future is hydrogen . The specialists claim the car. The reasons are clear: sources hydrogen in nature are nothing short of infinite, and it’s clean, because its combustion produces only water vapor. Reasons enough to interest the brands of cars.
The advantages of hydrogen as a fuel are known since long ago. Its mixture with oxygen causes a reaction such as spontaneous violent, whose end result is a harmless substance, while essential water. Sufficient to replace gasoline or diesel by hydrogen in a conventional engine to achieve the dream water car .
The theory is simple, but the practice is not so much. The hydrogen as fuel has practical drawbacks that have prevented its use as an energy source for cars, except for some experimental vehicles. For example, their ability to make burning dangerous maneuvers natural filling.
In addition, the hydrogen in natural gas and to have adequate reserves to ensure the same autonomy as conventional cars, it would be imperative to use liquid hydrogen. And this will only get hydrogen cooled to extremely low temperatures close to absolute zero (-273 ° C), so you need special deposits, known as Cryogenic , bulky, heavy and isolated for the low-temperature-based a lot of pressure.
At the end of 1999 , the researchers worked in a special tank made up of thousands of capillary tubes of a kind of carbon fiber, capable of storing large quantities of hydrogen.
The hydrogen is not as an independent in nature, but, combined, is one of the most abundant. It is part of the water, therefore, can provide an inexhaustible source of hydrogen. Water is composed only of hydrogen and oxygen.
The separation of both elements is done by electric current, through a process called electrolysis. So that there is some contamination, electricity used to be of solar or hydraulic.
