Electric cars are not a new concept as we think, people hve been using them for a long time .In fact in the 1900's people used more electric cars than cars run on gas.In the 1920's when the popularity for cars was growing, gas was very costly.Starting a gas run car was also a very tedious process, there was no key to ignite the engine, in fact a rod used to fit into the front of the car which had to be turned round and round to get the car started.
Not only were gas run cars tedious to start , they emitted alot of smoke and were very noisy, as either the mufflers used were not good or there were no mufflers at all. Beleive it or not , at one point of time electric cars were so popular that there were about 50,000 electric cars running on the streets of United States .
As new discoveries were underway to make gasoline cheaper, electric cars started disappearing from the market. The discovery of the electric starter made way for the exit of the crank and the car was started with a key.A car run on gas could travel more distance than the electric car.Thus cars run on gas started getting more pouplar than the electric car.
Now, once again because of the awareness towards protecting the environment and reducing the dangers caused by the emission of the greenhouse gases " green " electric cars are once again getting
popularized.
Gasoline is not used to run an electric car, it runs on the energy stored in batteries in the car. 12,14 or more batteries may be needed to run the car.The operation of the electric car is similar to that a remote controlled one since both have an electric motor that turns the wheel and a battery that that runs the motor.
Charging of the batteries can either be done all night or some cars need to be plugged into a standard electric wall.There are some which need a large electric outlet, something like what is used for an electric stove or electric clothes dryer. These are the various ways electricity is stored in the cars.
The batteries used to run the cars have to be either lead acid batteries, similar to those used in torch lights or ni-cad (nickel-cadium) used to run portable viodeo recorders or video games , only much larger in size. A lot of work is going on to upgrade the batteries to hold more energy and last longer. By the time the fifth graders in 2001 are ready to drive we should have electric cars which will be able to travel 150 to 200 miles before needing to get recharged.
Manufacturers of cars and scientists are making constant endeavours to make better cars which will be more eco-friendly. The revival of electric cars and the challenge to make them more attractive is on in a big way and enticing more people to switch over to electric cars.
