A solar bus or solar-charged bus is a bus that is powered exclusively or mainly by solar energy. Solar-powered bus service is referred to as a solar bus service. The use of the term "solar bus" normally implies that solar energy is used not only for powering electric equipment on the bus, but also for the propulsion of the vehicle. Existing solar buses are battery-electric buses or (in the case of hybrid solar buses) hybrid buses equipped with batteries that are recharged from solar (or other) power sources; a launch of solar bus service often goes hand in hand with investments for large-scale installations of stationary solar panels with photovoltaic cells. Similarly, like other solar vehicles, many solar buses have photovoltaic cells contained in solar panels on the vehicle's roof which converts the sun's energy directly into electric energy to be used by the engine. The introduction of solar buses and other green vehicles for purposes of public transport forms a part of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battery Electric Vehicle
A battery electric vehicle (BEV), pure electric vehicle, only-electric vehicle, fully electric vehicle or all-electric vehicle is a type of electric vehicle (EV) that exclusively uses chemical energy stored in rechargeable battery packs, with no secondary source of propulsion (a hydrogen fuel cell, internal combustion engine, etc.). BEVs use electric motors and motor controllers instead of internal combustion engines (ICEs) for propulsion. They derive all power from battery packs and thus have no internal combustion engine, fuel cell, or fuel tank. BEVs include – but are not limited to – motorcycles, bicycles, scooters, skateboards, railcars, watercraft, forklifts, buses, trucks, and cars. In 2016, there were 210 million electric bikes worldwide used daily. Cumulative global sales of highway-capable light-duty pure electric car vehicles passed the one million unit milestone in September 2016. , the world's top selling all-electric car in history is the Tesla Model 3, w ...

Solar Vehicle
A solar vehicle or solar electric vehicle is an electric vehicle powered completely or significantly by direct solar energy. Usually, photovoltaic (PV) cells contained in solar panels convert the sun's energy directly into electric energy. The term "solar vehicle" usually implies that solar energy is used to power all or part of a vehicle's propulsion. Solar power may be also used to provide power for communications or controls or other auxiliary functions. Solar vehicles are not sold as practical day-to-day transportation devices at present, but are primarily demonstration vehicles and engineering exercises, often sponsored by government agencies. However, indirectly solar-charged vehicles are widespread and solar boats are available commercially. Land Solar cars Solar cars are electric cars that use photovoltaic (PV) cells to convert sunlight into electrical power to charge the car's battery and to power the car's electric motors. Solar cars have been designed for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kaurna Language
Kaurna ( or ) is a Pama-Nyungan language historically spoken by the Kaurna peoples of the Adelaide Plains of South Australia. The Kaurna peoples are made up of various tribal clan groups, each with their own ''parnkarra'' district of land and local dialect. These dialects were historically spoken in the area bounded by Crystal Brook and Clare in the north, Cape Jervis in the south, and just over the Mount Lofty Ranges. Kaurna ceased to be spoken on an everyday basis in the 19th century and the last known native speaker, Ivaritji, died in 1929. Language revival efforts began in the 1980s, with the language now frequently used for ceremonial purposes, such as dual naming and welcome to country ceremonies. Classification R. M. W. Dixon (2002) classified Kaurna as a dialect of the Kadli language, along with Ngadjuri, Narungga, and Nukunu, and "Nantuwara", with ''kadli'' meaning "dog" in these varieties. However this name has not gained wide acceptance and is not recorded as a la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Green Vehicle
A green vehicle, clean vehicle, eco-friendly vehicle or environmentally friendly vehicle is a road motor vehicle that produces less harmful impacts to the environment than comparable conventional internal combustion engine vehicles running on gasoline or diesel, or one that uses certain alternative fuels. Presently, in some countries the term is used for any vehicle complying or surpassing the more stringent European emission standards (such as Euro6), or California's zero-emissions vehicle standards (such as ZEV, ULEV, SULEV, PZEV), or the low-carbon fuel standards enacted in several countries. Green vehicles can be powered by alternative fuels and advanced vehicle technologies and include hybrid electric vehicles, plug-in hybrid electric vehicles, battery electric vehicles, compressed-air vehicles, hydrogen and fuel-cell vehicles, neat ethanol vehicles, flexible-fuel vehicles, natural gas vehicles, clean diesel vehicles, and some sources also include vehicles using blend ...

Design Specification
A design specification is a detailed document that sets out exactly what a product or a process should present. For example, the design specification could include required dimensions, environmental factors, ergonomic factors, aesthetic factors, maintenance that will be needed, etc. It may also give specific examples of how the design should be executed, helping others work properly (a guideline for what the person should do). Example of a design specification An example design specification is shown below. Columns and information may be adjustable based on the output format (may be a physical product, or software, etc.) See also * Data sheet (Spec sheet) * Design by contract * Software requirements specification * Specification A specification often refers to a set of documented requirements to be satisfied by a material, design, product, or service. A specification is often a type of technical standard. There are different types of technical or engineering specificati .. ...

Powertrain
A drivetrain (also frequently spelled as drive train or sometimes drive-train) is the group of components that deliver mechanical power from the prime mover to the driven components. In automotive engineering, the drivetrain is the components of a motor vehicle that deliver power to the drive wheels. This excludes the engine or motor that generates the power. In marine applications, the drive shaft will drive a propeller, thruster, or waterjet rather than a drive axle, while the actual engine might be similar to an automotive engine. Other machinery, equipment and vehicles may also use a drivetrain to deliver power from the engine(s) to the driven components. In contrast, the powertrain is considered to include both the engine and/or motor(s) as well as the drivetrain. Function The function of the drivetrain is to couple the engine that produces the power to the driving wheels that use this mechanical power to rotate the axle. This connection involves physically linking the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lithium-ion Battery
A lithium-ion or Li-ion battery is a type of rechargeable battery which uses the reversible reduction of lithium ions to store energy. It is the predominant battery type used in portable consumer electronics and electric vehicles. It also sees significant use for grid-scale energy storage and military and aerospace applications. Compared to other rechargeable battery technologies, Li-ion batteries have high energy densities, low self-discharge, and no memory effect (although a small memory effect reported in LFP cells has been traced to poorly made cells). Chemistry, performance, cost and safety characteristics vary across types of lithium-ion batteries. Most commercial Li-ion cells use intercalation compounds as the active materials. The anode or negative electrode is usually graphite, although silicon-carbon is also being increasingly used. Cells can be manufactured to prioritize either energy or power density. Handheld electronics mostly use lithium polymer batteries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
