Alternative Methods of Transportation
New transportation options can help to cut back on greenhouse gasses and reduce air pollution in the environment.
Most people today now recognize the pitfalls of the automobile. North American society is addicted to the car, but the staggering amount of pollution (exhaust, noise, oil drilling, oil shipping and oil refining) caused by the fuelling of the internal combustion engine is very harmful to the environment.
While it seems unlikely that we will eliminate the car as a personal transportation system (at least anytime soon) there are many alternatives that are becoming more prevalent and practical.The majority (but not all, by any means) of these alternative transportation systems revolve around public transit for those who live in large cities.
At first glance mass transit seems like the perfect solution. It takes cars off the road and reduces pollution and congestion.
But what about rural populations where mass transit is impractical?
One of the most promising new innovations in mass transit is the creation of the hydrogen fuel cell as it is adapted to public buses.
The goal of the hydrogen fuel cell is to use the hydrogen that is naturally found in pure water as a fuel that can be burned yielding a waste product of oxygen.
Hydrogen burns much more completely and efficiently than gasoline and seems to hold the most promise among many alternative transportation methods.
There is also the possibility that a hydrogen fuel cell might be adapted to power our favorite automobile. This is promising because it would mean that as a society we would not have to change our personal habits, although the fuelling infrastructure would need to change.
If we don't have to change our habits it seems more likely that it will be adopted. It will also mean that those who live in rural areas where mass transit is unsuitable due to low population density will be able to avail themselves of this transportation alternative.
