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

In this essay I am going to be telling you about to what extent electric cars solve the fuel crisis. The critical steps are: 1. Evolve autos from gasoline/diesel to hybrid to plug-in hybrid. 2. Develop a battery that can run 200 miles on a 10-minute recharge. 3. Strengthen Briton’s electrical distribution system. 4. Recharge cars in garages‚ public places and service stations. 5. Build nuclear power plants to enlarge the supply of electricity. 6. Use all alternate sources of energy‚ i.e. wind

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.

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

first applications of electricity was the first incandescent light bulb in around 1870. The electric overhaul of society obviously brought many fresh new dangers with it‚ but it eliminated some of the old ones‚ like the naked flames of gas lighting that was commonly used in homes and factories then. The Joule heating effect that can be found in light bulbs is also present in electric heating. Electric heating has been thought of as wasteful in the past because in order to create that heat energy

The Advantages and Disadvantages of Electric Cars Introduction to Electric Cars An electric car is a vehicle which is driven by electric engines. The engines use electrical energy which is usually stored in batteries. Electric car is a variation of electric vehicle (EV). EV speaks of any vehicles which are propelled by electric engines. “Electric car” is a general term for high-speed vehicles which are powered by electricity. In the United States‚ low-speed vehicles which are powered by electricity
