Most cars use petrol, made from oil, which causes pollution and adds to global warming. Oil supplies are running out too. That's why car designers are turning to electric engines, which can use energy from cleaner sources. An electric car is an automobile that is propelled by one or more electric motors, using energy stored in rechargeable batteries. The first practical electric cars were produced in the 1880s.
The hydrogen tank stores enough fuel to power the car for 450 km.
The fuel cell chemically reacts hydrogen from the tank with oxygen from the air to make electricity.
The rechargeable battery stores energy released when the car brakes and helps the fuel cell power the car.
The power drive unit works like gear box. It makes more electricity flow from the battery to the motor.
The electric motor is light and compact, and turns the front wheels to drive the car along.
Few electric cars are 100 percent eco-friendly, because their batteries have to be charged using electricity. Most electricity still comes from power stations burning dirty fuels. These make pollution and add to global warming.
Honda FCX might look like an ordinary car but it's powered in what could be a much cleaner way. In a normal car, the engine burns petrol, releases energy, and makes pollution. But in this car the fuel tank is replaced by a kind of battery called a hydrogen fuel cell. This takes hydrogen from a tank and oxygen from the air, reacts them together, and produces electricity. The only waste product is stem, so if the hydrogen comes from a clean source there is no pollution at all.
Suzuki have created a single-seater electric pod that is great for short journeys. It is a three wheeled and low-speed city car. This made in Japan vehicle can travel not more than 30 kmph and the range is about 30 km. Two of the Pixy pods can sit in a fuel-cell coach that recharges them as it moves. The larger coach can go on longer journeys.
Micro cab is useful for short journeys and top speed is 64 kmph where range is 80-160 km and made in United Kindom. Fuel cells are being used as taxis in Birmingham, England. They are incredibly light and car travel for 160 km before they need to stop and fuel.
The life car is built from lightweight aluminum which is stylish and speedy fuel-cell sports car. This car speeds up to 140 kmph and range is about 320 km. This United Kingdom car uses five times less energy than an ordinary steel-bodied car. It speeds from 0-100kmph. in 7 seconds!
Venturi Astrolab is a solar car with no engine or no fuel cell. This high-performance car powered by sunlight can speed up to 120 kmph and range is about 110 km. This car is made in France. It's covered in solar panels with lenses on top. These capture sunlight, turn it into electricity, and store it in batteries.
The tesla is designed for people who love ordinary cars but want them to be environmentally friendly as well. This car is fast and can go up to 210 kmph which is more than ordinary cars and range is about 400 km. This car is made in USA. Its powerful electric motor can accelerate almost as fast as a petrol driven Ferrari!
Tesla road roaster is 100 per cent electric and is powered by 6831 laptop batteries. The lithium-ion battery pack takes three and half hours to charge and burns no oil. It can accelerate to 100 kmph in just 4 seconds. So, what are you waiting for just buy an eco-friendly electric car and have a pollution free journey!
