The cars of tomorrow
The instability of oil prices, its more than likely expiration date medium to long term and "green" that is looming in some governments, including the U.S. , a leader in pollution, is a point turning for manufacturers to start, or retrieve your files, alternative energy projects to move their vehicles.
A need for change that comes with a rush that could have been avoided if products such as Citroen Saxo / Berlingo Electric had received more support from the media or consumers. A high price and poor, or no publicity was made to stop a car that everyone would like to make today. GM ended its EV1 project without ever studying the market. Different destination than the Toyota Prius, which despite having passed almost unnoticed and discrete sales numbers until recently, can boast of being a pioneer and respect as a vehicle powered by a hybrid engine. But the need for renewal has opened a war between engine manufacturers to achieve the final, instead of joining forces to more efficient technology. Thus we have a range of possibilities for the coming years. Cars helped or driven by electric motors, combustion engines that use alternative fuels and even compressed air powered cars that are still experimental.
As for cars with electric motors, we can differentiate between pure electric, hybrid and fuel cell.
The pure electric car is one that stores energy in rechargeable batteries and uses it to move one or more motors. Its acceleration level performance is superior to other technologies. In contrast, the maximum range and speed are still very limited. For this reason is almost relegated to urban use, favored also by its zero emissions and low noise.
The hybrid car combines two types of use of the engine. In parallel, that is, both motors can drive the wheels, usually the electrical works in solitary below 50 km / h accompanying the explosion acceleration. Be a series hybrid, when the combustion engine only responsible for producing electric power for moving the wheels. Both solve the problem of autonomy and speed of car batteries, but give off noxious gases. Still significantly reduce consumption. 
The fuel cell cars use a tank of hydrogen , which, by electrolysis is converted into energy to drive an electric motor. Its performance is exactly equal to the car battery, but increasing their autonomy because we can fill up when it started to call, hidrogeneras, which are only stations with hydrogen supplier. The only thing that expels its exhaust is water vapor.
There are also some combustion engine adapted to use hydrogen as fuel, but we will review these other options in the next article that will try to explain all the fossil fuels that bet the manufacturers.
