Knowing the increasing problems of pollution and its effects to the human beings and the environment at large, it has become a need of every conscious literate to think about the alternatives to save the environment and the human society. We shall have to think on the future needs of bearing the environmental responsibilities along with being professional enough to make it an ideal choice for the real world functionality. Emerging needs of alternate fuel arrangements has been a hot issue in the world today.
Pure Electric
Electric vehicles cause zero emission and no noise. They run on batteries that can be charged overnight by plugging it in to an electric outlet. The only moving part is an electric motor that makes the vehicle completely maintenance free. A drive system drives the vehicle and a control system offers controls as per the need of a regular vehicle. An EV is hence, noiseless, a zero emission vehicle best used for intracity transport needs and for commuters traveling short distances. One charge of battery offers 80-100 kms with as cheap as 80 paise per km for a four seater car.
Hybrid Electric
Hybrid electric cars are vehicles that use electric batteries and gasoline to power them. Toyota and Honda already have their version of the hybrid electric car on the market. The logic behind a hybrid electric car is that the gas will power the acceleration of the car then when it gets up to speed the electric battery motor kicks in. There is no need to ever charge up these type of vehicles because the gasoline motor charges the battery while driving.
Fuel Cell
A fuel cell is an electrochemical device that produces electricity efficiently, silently and without combustion. Hydrogen fuel (which can be obtained from methanol, natural gas, water, or petroleum products) is combined with oxygen (from air) to produce electrical energy. Fuel cells and batteries are similar as they both deliver electrical power from a chemical reaction. However, in a battery, the chemical reactants are stored within the battery, are used up during the reaction and the battery must be recharged or thrown away. In a fuel cell, the reactants are stored externally to the fuel cell, so it will keep producing electricity as long as reactants (fuels) are delivered to the fuel cell. Therefore a fuel cell vehicle is refueled instead of recharged.
