Hybrid Electric Bus
A hybrid electric bus is a bus that combines a conventional internal combustion engine propulsion system with an electric propulsion system. These types of buses normally use a diesel–electric powertrain and are also known as hybrid diesel–electric buses. The introduction of hybrid electric vehicles and other green vehicles for purposes of public transport forms a part of sustainable transport schemes. Powertrain Types of hybrid vehicle drivetrain A hybrid electric bus may have either a parallel powertrain (e.g., Volvo B5LH) or a series powertrain (e.g., some versions of the Alexander Dennis Enviro400 MMC). Since 2003, Allison Transmission has produced dual-mode hybrid drive units which take the place of a conventional transmission, mostly for transit buses in North America; as the name implies, it is able to switch between series and parallel modes. Plug-in hybrid A plug-in hybrid school bus effort began in 2003 in Raleigh, NC, when Advanced Energy began ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Vehicle
An electric vehicle (EV) is a motor vehicle whose propulsion is powered fully or mostly by electricity. EVs encompass a wide range of transportation modes, including road vehicle, road and rail vehicles, electric boats and Submersible, submersibles, electric aircraft and electrically powered spacecraft propulsion, electric spacecraft. Early electric vehicles first came into existence in the late 19th century, when the Second Industrial Revolution brought forth electrification and mass utilization of DC motor, DC and AC motor, AC electric motors. Using electricity was among the preferred methods for motor vehicle propulsion as it provided a level of quietness, comfort and ease of operation that could not be achieved by the gasoline engine cars of the time, but range anxiety due to the limited energy storage offered by history of the battery, contemporary battery technologies hindered any mass adoption of private electric vehicles throughout the 20th century.

Electric Range
An electric stove, electric cooker or electric range is a stove with an integrated electrical heating device to cook and bake. Electric stoves became popular as replacements for solid-fuel (wood or coal) stoves which required more labor to operate and maintain. Some modern stoves come in a unit with built-in extractor hoods. The stove's one or more "burners" (heating elements) may be controlled by a rotary switch with a finite number of positions; or may have an " infinite switch" called a ''simmerstat'' that allows constant variability between minimum and maximum heat settings. Some stove burners and controls incorporate thermostats. History Early patents On September 20, 1859, George B. Simpson was awarded US patent #25532 for an 'electro-heater' surface heated by a platinum-wire coil powered by batteries. In his words, useful to "warm rooms, boil water, cook victuals...". Canadian inventor Thomas Ahearn filed patent #39916 in 1892 for an "Electric Oven," a device he proba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tyne And Wear
Tyne and Wear () is a Ceremonial counties of England, ceremonial county in North East England. It borders Northumberland to the north and County Durham to the south, and the largest settlement is the city of Newcastle upon Tyne. The county is largely urbanised, with a population of 1.14 million in 2021. After Newcastle, the largest settlements are the city of Sunderland, Gateshead, and South Shields. Nearly all of the county's settlements belong to the Tyneside or Wearside conurbations, the latter of which extends into County Durham. For local government purposes Tyne and Wear comprises five metropolitan boroughs: Metropolitan Borough of Gateshead, Gateshead, Newcastle upon Tyne, City of Sunderland, Sunderland, North Tyneside and South Tyneside. The borough councils collaborate through the North East Combined Authority, which also includes Durham County Council and Northumberland County Council.

QuayLink
QuayLink was a bus service in Tyne and Wear, England, which connected Gateshead and Newcastle upon Tyne, and later North Tyneside, with the Quayside. Funded by the Tyne and Wear Passenger Transport Executive, the service was launched on 22 July 2005. Operated initially by Stagecoach North East, the service was transferred to Go North East in July 2010 – later being operated commercially from July 2015, following budget cuts. History QuayLink was designed as a frequent, high quality bus service, for the newly developed and expanding Quayside area. Despite being located a short distance from the town centre of Gateshead and city centre of Newcastle upon Tyne, the area was poorly served by public transport. In June 2002, both Gateshead Council and Newcastle City Council, along with the Tyne and Wear Passenger Transport Executive, invited tenders for operation of a proposed Tyne Quayside Link, as well as the manufacture of eight alternatively-fuelled buses. The proposed project ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gas Turbine
A gas turbine or gas turbine engine is a type of Internal combustion engine#Continuous combustion, continuous flow internal combustion engine. The main parts common to all gas turbine engines form the power-producing part (known as the gas generator or core) and are, in the direction of flow: * a rotating gas compressor * a combustor * a compressor-driving turbine. Additional components have to be added to the gas generator to suit its application. Common to all is an air inlet but with different configurations to suit the requirements of marine use, land use or flight at speeds varying from stationary to supersonic. A propelling nozzle is added to produce thrust for flight. An extra turbine is added to drive a propeller (turboprop) or ducted fan (turbofan) to reduce fuel consumption (by increasing propulsive efficiency) at subsonic flight speeds. An extra turbine is also required to drive a helicopter rotor or land-vehicle transmission (turboshaft), marine propeller or electric ...

Greenhouse Gas Emissions
Greenhouse gas (GHG) emissions from human activities intensify the greenhouse effect. This contributes to climate change. Carbon dioxide (), from burning fossil fuels such as coal, petroleum, oil, and natural gas, is the main cause of climate change. The top contributors to greenhouse gas emissions, largest annual emissions are from China followed by the United States. The United States has List of countries by greenhouse gas emissions per capita, higher emissions per capita. The main producers fueling the emissions globally are Big Oil, large oil and gas companies. Emissions from human activities have increased Carbon dioxide in Earth's atmosphere, atmospheric carbon dioxide by about 50% over pre-industrial levels. The growing levels of emissions have varied, but have been consistent among all greenhouse gases. Emissions in the 2010s averaged 56 billion tons a year, higher than any decade before. Total cumulative emissions from 1870 to 2022 were 703 (2575 ), of which 484±20 (177 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biodiesel
Biodiesel is a renewable biofuel, a form of diesel fuel, derived from biological sources like vegetable oils, animal fats, or recycled greases, and consisting of long-chain fatty acid esters. It is typically made from fats. The roots of biodiesel as a fuel source can be traced back to when J. Patrick and E. Duffy first conducted transesterification of vegetable oil in 1853, predating Rudolf Diesel's development of the diesel engine. Diesel's engine, initially designed for mineral oil, successfully ran on peanut oil at the 1900 Paris Exposition. This landmark event highlighted the potential of vegetable oils as an alternative fuel source. The interest in using vegetable oils as fuels resurfaced periodically, particularly during resource-constrained periods such as World War II. However, challenges such as high viscosity and resultant engine deposits were significant hurdles. The modern form of biodiesel emerged in the 1930s, when a method was found for transforming vegetable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ultracapacitor
alt=Supercapacitor, upright=1.5, Schematic illustration of a supercapacitor upright=1.5, A diagram that shows a hierarchical classification of supercapacitors and capacitors of related types A supercapacitor (SC), also called an ultracapacitor, is a high-capacity capacitor, with a capacitance value much higher than solid-state capacitors but with lower voltage limits. It bridges the gap between electrolytic capacitors and rechargeable batteries. It typically stores 10 to 100 times more energy per unit volume or mass than electrolytic capacitors, can accept and deliver charge much faster than batteries, and tolerates many more charge and discharge cycles than rechargeable batteries. Unlike ordinary capacitors, supercapacitors do not use the conventional solid dielectric, but rather, they use electrostatic double-layer capacitance and electrochemical pseudocapacitance, both of which contribute to the total energy storage of the capacitor. Supercapacitors are used in applicati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
