Hybrid vehicles were the stuff of dreams centuries ago. Nobody ever thought that creating a vehicle independent from fuel was possible. Fortunately with the continuing development of hybrid technology, more efficient and practical vehicles have been created. In the recent years the campaign for global warming has brought the attention of the public. Hybrid cars are now becoming steadily popular available in different types from compact sedans to SUVs.
Environmental issues are not the only reason that has made the public favor hybrid cars. Rising gas prices is also one of the major reasons why people prefer hybrid cars than conventional ones. Its also practical in suburban environments where you don't really need horsepower but gas mileage.
Hybrid Vehicles
There are different types of hybrid vehicles. They can vary from the simplest wheelbarrows to ships. No matter what form they are, these vehicles help in reducing greenhouse and noise emissions. Although these vehicles are expensive due to their unique structures, developments will continue to provide more alternatives to the public. These cars may not compare to conventional ones with a 200 horsepower but why would you need that if you only need 20 in the streets?
The simplest hybrid would be the single wheeled vehicles. These are wheelbarrows famously depicted with sails. This can be seen in Chinese sailing carriages.
The next is two wheeled vehicles. These are usually cycle type vehicles. The best example would be the Moped and electric bicycles. They are powered by an electric motor or an internal combustion engine in combination with the rider's muscles. This concept was also used in the 1800's by motorcycles. The electric bicycle can either be a parallel or a series hybrid.
Hybrid vehicles are not just limited to private cars. There are also hybrid power trains used by heavy vehicles. There are diesel or turbo electric buses, railway locomotives, heavy duty vehicles, hydraulic machinery and ships.
In ships a diesel engine drives the electric generator or hydraulic pump which in turn powers one or more hydraulic or electric motors. Sails and engines were early forms of hybrids which may be used again due to rising fuel costs.
More developments are continually being made in hybrid structures and systems for efficiency. Today buying a hybrid car is expensive but it will be beneficial in the long run. It does not just save fuel costs but also removes pollution that can harm the health of the people and take whatever it is left of the environment.
