Electric Cars An electric car is a vehicle which gets power from one electric motor or more‚ and an electric car use electrical energy to store batteries or another energy storage device. The developmental history of electric cars is very long‚ and the first automobile all over the world was an electric car. However‚ electric cars had two terrible disadvantages: the problem of energy technology and mileage limit around 20 century. The problems made electric cars disappeared from citizens eyes for

Our Electric Bicycle Project I have added an electric power assist onto a GT mountain bike. With a 3 HP peak motor‚ it is much more powerful than typical electric bicycles. The basic motivation to build an electric bike was to have a fun and efficient and environmentally friendly way to stay out my car for short trips around town‚ and also as a silent trail bike for exploring the hills. I wanted to get some exercise - this bike can still be pedaled. When I first put this together it was even more

Electric cars vs the gas oh line cars In the next ten years what the average American drives will be very different than today. Electric cars may phase out gasoline (Gasoline is also known as petrol) in the next couple of decade. Electric cars produce no tailpipe emissions and are much cheaper to fill up than the more common gasoline vehicles. Switching to electric cars will have more benefits than drawbacks in comparison to other fuels such as petrol and diesel. In order to switch to electric

Chapter 1 The History of Electric Transformer INTRODUCTION: Transformer is a device that transfers electric energy from one circuit to another‚ usually with a change in voltage. Transformers work only with a varying electric current‚ such as alternating current (AC). Transformers are important in the distribution of electric power. They raise the voltage of the electricity generated at a power plant to the high levels needed to transmit the electricity efficiently. Other transformers

In electricity generation‚ an electric generator is a device that converts mechanical energy to electrical energy. A generator forces electrons in the windings to flow through the external electrical circuit. It is somewhat analogous to a water pump‚ which creates a flow of water but does not create the water inside. The source of mechanical energy may be a reciprocating or turbine steam engine‚ water falling through a turbine or waterwheel‚ an internal combustion engine‚ a wind turbine‚ a hand crank

Advantages and Disadvantages of Electric Vehicles Almost all households in this world uses a gas powered vehicles which causes the greenhouse effect or more known as the global warming. The global warming itself is caused by the emission of the gas powered vehicles. To prevent this‚ technologists have invented a vehicle that uses electricity. Although there are many benefits‚ in a developing countries‚ owning and using an electric car results in having both advantages and also disadvantages.
