REVAi
The REVA''i'', known as G-Wiz in the United Kingdom, is a small micro electric car, made by the Indian manufacturer Reva Electric Car Company between 2001 and 2012. By late 2013 Reva had sold about 4,600 vehicles worldwide, in 26 countries. Sales in the United Kingdom, its main market, and was replaced by the Mahindra e2o. In many countries the REVA''i'' does not meet the criteria to qualify as a highway-capable motor vehicle, and fits into other classes, such as neighborhood electric vehicle (NEV) in the United States and heavy quadricycle in Europe. The vehicle was originally known as simply the REVA, but was then improved and renamed the REVA''i''. Design The REVA''i'' is a small three-door hatchback measuring long, wide and high. The car can accommodate two adults in the front and two children in the rear. The back seats can be folded down to provide cargo space. The maximum passenger and cargo weight is . The REVA''i'' is intended for city trips and commuting, ...

Mahindra E2o
The Mahindra e2o, previously Reva NXR, is an urban electric car hatchback manufactured by Mahindra Reva or Reva Electric Vehicles in 2013–2017. The e2o is the successor of the REVAi (or G-Wiz as it was known in the UK) and was developed using Reva's technology, and has a range of . In 2006, the G-Wiz became the world's best-selling electric vehicle and by 2008, the company managed to sell over 950 G-Wiz electric cars, making it the UK's best-selling electric car of all time at that time (the record was later surpassed by the Nissan LEAF, with over 14,000 sold by 2016; the LEAF was in turn surpassed by the Mitsubishi Outlander, with over 23,000 sold in the UK by the end of 2016). The e2o, a two-door, four-seater hatchback, is equipped with features like automatic transmission and allows the buyer to lock the car and operate the air conditioning using a mobile application. According to Forbes, the car "will inoculate its buyers from rising gas prices, provide relief from tai ...

Charging Station
A charging station, also known as a charge point or electric vehicle supply equipment (EVSE), is a piece of equipment that supplies electrical power for charging plug-in electric vehicles (including electric cars, electric trucks, electric buses, neighborhood electric vehicles, and plug-in hybrids). There are two main types: AC charging stations and DC charging stations. Batteries can only be charged with direct current (DC) electric power, while most electricity is delivered from the power grid as alternating current (AC). For this reason, most electric vehicles have a built-in AC-to-DC converter, commonly known as the "onboard charger". At an AC charging station, AC power from the grid is supplied to this onboard charger, which produces DC power to charge the battery. DC chargers facilitate higher power charging (which requires much larger AC-to-DC converters) by building the converter into the charging station instead of the vehicle to avoid size and weight restrictions. ...

Microcar
Microcar is a term often used for the smallest size of cars, with three or four wheels and often an engine smaller than . Specific types of microcars include bubble cars, cycle cars, invacar, quadricycles and voiturettes. Microcars are often covered by separate regulations to normal cars, having relaxed requirements for registration and licensing. Predecessors Voiturette is a term used by some small cars and tricycles manufactured from 1895 to 1910. Cyclecars are a type of small, lightweight and inexpensive car manufactured mainly between 1910 and the late 1920s. Europe 1940-1970: Microcars The first cars to be described as microcars (earlier equivalents were called voiturettes or cyclecars) were built in the United Kingdom and Germany following World War II, and remained popular until the 1960s. They were originally called minicars, but later became known as microcars. France also produced large numbers of similar tiny vehicles called voiturettes, but they were ...

Solar Energy
Solar energy is radiant light and heat from the Sun that is harnessed using a range of technologies such as solar power to generate electricity, solar thermal energy (including solar water heating), and solar architecture. It is an essential source of renewable energy, and its technologies are broadly characterized as either passive solar or active solar depending on how they capture and distribute solar energy or convert it into solar power. Active solar techniques include the use of photovoltaic systems, concentrated solar power, and solar water heating to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light-dispersing properties, and designing spaces that naturally circulate air. The large magnitude of solar energy available makes it a highly appealing source of electricity. In 2020 solar energy has been the cheapest source of Electricity. In Saudi Arabia a power purchase agre ...

Disc Brakes
A disc brake is a type of brake that uses the calipers to squeeze pairs of pads against a disc or a "rotor" to create friction. This action slows the rotation of a shaft, such as a vehicle axle, either to reduce its rotational speed or to hold it stationary. The energy of motion is converted into waste heat which must be dispersed. Hydraulically actuated disc brakes are the most commonly used form of brake for motor vehicles, but the principles of a disc brake are applicable to almost any rotating shaft. The components include the disc, master cylinder, and caliper (which contains a cylinder and two brake pads) on both sides of the disc. Design The development of disc-type brakes began in England in the 1890s. In 1902, the Lanchester Motor Company designed brakes that looked and operated in a similar way to a modern disc-brake system even though the disc was thin and a cable activated the brake pad. Other designs were not practical or widely available in cars for another 6 ...

Drum Brakes
A drum brake is a brake that uses friction caused by a set of shoes or pads that press outward against a rotating cylinder-shaped part called a brake drum. The term ''drum brake'' usually means a brake in which shoes press on the inner surface of the drum. When shoes press on the outside of the drum, it is usually called a ''clasp brake''. Where the drum is pinched between two shoes, similar to a conventional disc brake, it is sometimes called a ''pinch drum brake'', though such brakes are relatively rare. A related type called a band brake uses a flexible belt or "band" wrapping around the outside of a drum. History The modern automobile drum brake was first used in a car made by Maybach in 1900, although the principle was only later patented in 1902 by Louis Renault. He used woven asbestos lining for the drum brake lining, as no alternative dissipated heat like the asbestos lining, though Maybach had used a less sophisticated drum brake. In the first drum brakes, levers a ...

London Congestion Charge
The London congestion charge is a fee charged on most cars and motor vehicles being driven within the Congestion Charge Zone (CCZ) in Central London between 7:00 am and 6:00 pm Monday to Friday, and between 12:00 noon and 6:00 pm Saturday and Sunday. Inspired by Singapore's Electronic Road Pricing (ERP) system after London officials had travelled to the country, the charge was first introduced on 17 February 2003. The London charge zone is one of the largest congestion charge zones in the world, despite the removal of the Western Extension which operated between February 2007 and January 2011. The charge not only helps to reduce high traffic flow in the city streets, but also reduces air and noise pollution in the central London area and raises investment funds for London's transport system. The standard charge is £15, every day from 7:00 am to 6:00 pm, for each non-exempt vehicle driven within the zone, with a penalty of between £65 and £195 levied for non-payment. The c ...
