Elektriautod

refers to any vehicle that uses electric motors for propulsion, while "electric car" generally refers to road-going automobiles powered by electricity. While an electric car's power source is not explicitly an on-board battery, electric cars with motors powered by other energy sources are generally referred to by a different name: an electric car powered by sunlight is a solar car, and an electric car powered by a gasoline generator is a form of hybrid car. Thus, an electric car that derives its power from an on-board battery pack is a form of battery electric vehicle (BEV). Most often, the term "electric car" is used to refer to pure battery electric vehicles. What types electric cars we have Usual electric cars have a batterey and elecrtic motor jusr like toy cars. Hybrid vehicle Then we have already hybrid vehicle (HEV) is a type of hybrid vehicle and electric

6,5 per cent and petrol cars declined 5,3 per cent. Consumers are purchasing more diesel engine cars which have smaller fuel consumption. For that reason drivers can save money on the fuel.(http://academic.mintel.com E) Political Drivers are more likely to buy a small car with a smaller engine; then they will have lower taxes for their vehicle. The government is also trying to lead UK car production and car demand towards the fully electrical and hybrid electric cars. But it is not so easy because of the low demand and high production costs. Although in 2009 fully electric and hybrid electric cars have made a rise from 16000 to 20000. It might be because of the scrappage scheme, when customers get £2000 discount for buying a new car. Also when consumer wants to buy himself/herself a new Mini then the discount will apply. The government started scrappage

Environment and transportation

The following 10 activities will be a great help in solving our transportation problems. Do as many of these as you can, and encourage your friends and family to do the same. Together we can make a difference! 1. Get a Better Vehicle --- If you need to drive, replace your old car with one of the new hybrid gas and electric cars - and you could save as much as $11,000 on gas and produce 107 fewer tons of carbon dioxide. The new efficient hybrids are reliable and drive just like standard cars. If you make no other transportation changes in your life, this one will make a huge difference. 2. Walk to Your Destination --- If it's a reasonable distance, you'll save energy and improve your health. Walking also helps to reduce tension and stress. Get some good walking shoes, dress for the weather, and hoof it! 3. Ride Your Bike --- If you need to travel a greater distance, take your bike. Again, it's good exercise, it feels great and it's fun. 4. Take a Bus --- Many communities have a pub

Electric car (biological cars)

Limitations · The large mass of the batteries. · Battery charging time, but there are ways to "quick charge" to the part-time battery capacity. · In most cases, low dynamic performance. · In some hybrids in general there are no electric batteries. · The major auto companies after the 2000s, paid little attention to electric cars in favor of hybrids. and many other Advantages · Overall simplicity of design and management in comparison with hybrid vehicles. · lower number mechanical parts and components. · Improved reliability. · Ease of repair and service, and as a result, and lower operation cost. · Less pollution. No transmission unlike mechanical hybrids. modern Application The world leader in electric transportation - China. widely used in various enterprises are widely used for transportation of goods in railway stations, shops and large stores, as well as an attraction. models electric cars

robustness are required. Fixed pitch propellers are usually installed for ocean sailing vessels, for example Container vessels Tankers Bulk carriers Dry cargo vessels 1.3) The Rolls-Royce gearbox range is based on the single-input single-output design with built- in clutch and thrustblock - and a wide variety of power-take-offs that enable large-shaft generators to be driven - and electric motors to feed power for get-you-home propulsion or as part of a hybrid propulsion system. The input shaft is provided with keyway for mounting of the flexible coupling and the output shaft with a cylindrical shaft or flange. 2) Auxiliary machinery 2.1)Generator As you know that a ship is a mobile power plant or a moving mini-city. Air comp these moving giants have a pre-designed and erected compressed air system, which facilitates many activities onboard a ship. There are mostly 4 to 8 and sometimes 10 air compressors found onboard. These air compressors

GLOBAL WARMING Global warming is the observed century-scale rise in the average temperature of Earth's climate system. Since 1971, 90% of the increased energy has been stored in the oceans, mostly in the 0 to 700m region. Despite the oceans' dominant role in energy storage, the term "global warming" is also used to refer to increases in average temperature of the air and sea at Earth's surface. Since the early 20th century, the global air and sea surface temperature has increased about 0.8 °C (1.4 °F), with about two-thirds of the increase occurring since 1980.Each of the last three decades has been successively warmer at the Earth's surface than any preceding decade since 1850. More than 90% certain that most of global warming was being caused by increasing concentrations of greenhouse gases produced by human activities.In 2010 that finding was recognized by the national science academies of all major industrialized nations. Affirming these findin
