How Modern Transport Fuels Effect our Environment

Why is looking at alternate fuels important? There are several reasons, but the most important reason is that air pollution kills in the neighborhood of 3 million people every year and air pollution affects more than 1 billion people in a negative way. That 's over 1/6 of the earths population being harmed by air pollution, that 's a trend that cannot continue without extreme repercussions to everyone on the planet.

Granted, air pollution created by cars is not the only pollution on the planet but it is imperative to begin with what pollutes the air and atmosphere first. How are we going to do that? Is it by keeping the status quo and allowing these harmful pollutants to

At this point BMW has showcased its fleet of hydrogen powered vehicle very successfully and hope 's to have the cars on the market in Europe in 2005.

Before thinking that Hydrogen is ready for use right now, it should be noted that there are issues to be resolved to make this system work as perfectly as it should. As mentioned earlier, BMW has achieved some measure of success with their hydrogen fueled vehicles, but what was not mentioned is that in order for this fuel to work properly in these cars, it has to be compressed enough to provide the required amount to make it practical (around 400 miles from a full tank) therefore it has to be cooled to a temperature of -423 degrees Fahrenheit. BMW has safely achieved this with its fuel tank, but now needs to make the fuel tank cost effective and mass produce it. If it were not cooled, the fuel tank would be too large for any automobile. Also the fuel tank would have to be insulated and designed to keep it at that temperature and because it is compressed it would need to withstand 10,000 psi – 50 times the pressure of a normal gas tank.

The infrastructure is a large problem to overcome: how to begin manufacturing, storing and building or retrofitting fueling stations across the nation, this in itself is an enormous economic undertaking to overcome. It will require a commitment from the private and government sector similar
