Scooter (motorcycle)
A scooter (also referred to as a motor scooter to avoid confusion with kick scooter) is a type of motorcycle with step-through frame and a platform for the rider's feet. Elements of scooter design have been present in some of the earliest motorcycles, and motorcycles identifiable as scooters have been made from 1914 or earlier. Scooter development continued in Europe and the United States between the World Wars. The global popularity of scooters dates from the post-World War II introductions of the Vespa and the Lambretta. These scooters were intended to provide economical personal transportation (engines from ).
Electric bicycle laws
Many countries have enacted electric bicycle laws to regulate the use of electric bicycles. Countries such as the United States and Canada have federal regulations governing the safety requirements and standards of manufacture. Other countries like the signatories of the European Union have agreed to wider-ranging legislation covering use and safety of their term EPAC (electric pedal-assisted cycles). However, confusion remains regarding the various laws involving electric bicycles. This stems from the fact that while some countries have national regulations, the legality of road use is left to states and provinces, and then complicated further by municipal laws and restrictions.
Moto Guzzi
Moto Guzzi is an Italian motorcycle manufacturer and the oldest European manufacturer in continuous motorcycle production. Established in 1921 in Mandello del Lario, Italy, the company is noted for its historic role in Italy's motorcycling manufacture, its prominence worldwide in motorcycle racing, and industry innovations—including the first motorcycle centre stand, wind tunnel and eight-cylinder engine. Since 2004, Moto Guzzi has been a "unico azionista", a wholly owned subsidiary, and one of seven brands owned by Piaggio & C. SpA, Europe's largest motorcycle manufacturer and the world's fourth largest motorcycle manufacturer by unit sales.
Honda Super Cub
The Honda Super Cub is a Honda underbone motorcycle with a four stroke single cylinder engine ranging in displacement from . In continuous manufacture since 1958 with production surpassing 60 million in 2008, 87 million in 2014, and 100 million in 2017, the Super Cub is the most produced motor vehicle in history. Variants include the C100, C50, C70, C90, C100EX and C70 Passport. The Super Cub's US advertising campaign, You meet the nicest people on a Honda, had a lasting impact on Honda's image and on American attitudes to motorcycling, and is often used as a marketing case study. The idea for a new "" motorcycle was conceived in 1956, when Honda Motor's Soichiro Honda and Takeo Fujisawa toured Germany and witnessed the popularity of mopeds and lightweight motorcycles.
Vespa
Vespa () is an Italian brand of scooter manufactured by Piaggio. The name means wasp in Italian. The Vespa has evolved from a single model motor scooter manufactured in 1946 by Piaggio & Co. S.p.A. of Pontedera, Italy to a full line of scooters and one of seven companies today owned by Piaggio. From their inception, Vespa scooters have been known for their painted, pressed steel unibody which combines a complete cowling for the engine (enclosing the engine mechanism and concealing dirt or grease), a flat floorboard (providing foot protection), and a prominent front fairing (providing wind protection) into a structural unit.
Harley-Davidson
Harley-Davidson, Inc. (H-D), or Harley, is an American motorcycle manufacturer, founded in Milwaukee, Wisconsin in 1903. One of two major American motorcycle manufacturers to survive the Great Depression (along with Indian), the company has survived numerous ownership arrangements, subsidiary arrangements (e.g., Aermacchi 1974-1978 and Buell 1987-2009), periods of poor economic health and product quality, as well as intense global competition, to become one of the world's largest motorcycle manufacturers and an iconic brand widely known for its loyal following. There are owner clubs and events worldwide as well as a company-sponsored brand-focused museum.
Electric motorcycles and scooters
Electric motorcycles and scooters are plug-in electric vehicles with two or three wheels powered by electricity. The electricity is stored on board in a rechargeable battery, which drives one or more electric motors. Electric scooters (as distinct from motorcycles) have a step-through frame. The early history of electric motorcycles is somewhat unclear. On 19 September 1895, a patent application for an "electrical bicycle" was filed by Ogden Bolton Jr. of Canton Ohio. On 8 November of the same year, another patent application for an "electric bicycle" was filed by Hosea W. Libbey of Boston. At the Stanley Cycle Show in 1896 in London, England, bicycle manufacturer Humber exhibited an electric tandem bicycle.

Economic history of the United States
The economic history of the United States is about characteristics of and important developments in the U.S. economy from colonial times to the present. The emphasis is on economic performance and how it was affected by new technologies, the change of size in economic sectors and the effects of legislation and government policy. Specialized business history is covered in American business history. The colonial economy differed significantly from that of most other regions in that land and  natural resources were abundant in America but labor was scarce. From 1700 to 1775 the output of the thirteen colonies increased 12 fold, giving the colonies an economy about 30% the size of Britain's at the time of independence.
Jet engine
A jet engine is a reaction engine discharging a fast-moving jet that generates thrust by jet propulsion. This broad definition includes airbreathing jet engines (turbojets, turbofans, ramjets, and pulse jets) and non-airbreathing jet engines (such as rocket engines). In general, jet engines are combustion engines. In common parlance, the term "jet engine" loosely refers to an internal combustion airbreathing jet engine. These typically feature a rotating air compressor powered by a turbine, with the leftover power providing thrust via a propelling nozzle — this process is known as the Brayton thermodynamic cycle.
Fuel economy in automobiles
The fuel economy of an automobile is the relationship between the distance traveled and the amount of fuel consumed by the vehicle. Consumption can be expressed in terms of volume of fuel to travel a distance, or the distance travelled per unit volume of fuel consumed. Since fuel consumption of vehicles is a significant factor in air pollution, and since importation of motor fuel can be a large part of a nation's foreign trade, many countries impose requirements for fuel economy. Different methods are used to approximate the actual performance of the vehicle. The energy in fuel is required to overcome various losses (wind resistance, tire drag, and others) encountered while propelling the vehicle, and in providing power to vehicle systems such as ignition or air conditioning.
Scooter (motorcycle)
A scooter (also referred to as a motor scooter to avoid confusion with kick scooter) is a type of motorcycle with step-through frame and a platform for the rider's feet. Elements of scooter design have been present in some of the earliest motorcycles, and motorcycles identifiable as scooters have been made from 1914 or earlier. Scooter development continued in Europe and the United States between the World Wars. The global popularity of scooters dates from the post-World War II introductions of the Vespa and the Lambretta. These scooters were intended to provide economical personal transportation (engines from ).
Fuel economy in aircraft
Fuel economy in aircraft is a measure of how much fuel an aircraft, or a fleet of aircraft of mixed types, needs to operate in relation to a service provided (i.e. number of passengers or ton of freight) and the distance between points of travel. It can be expressed in several ways, for example by the litres of fuel consumed per passenger per kilometer. A powered aircraft counters its weight through aerodynamic lift and counters its aerodynamic drag with thrust. The aircraft's maximum range is determined by the level of efficiency with which thrust can be applied to overcome the aerodynamic drag.
Energy policy of the United States
The energy policy of the United States is determined by federal, state, and local entities in the United States, which address issues of energy production, distribution, and consumption, such as building codes and gas mileage standards. Energy policy may include legislation, international treaties, subsidies and incentives to investment, guidelines for energy conservation, taxation and other public policy techniques. Several mandates have been proposed over the years, such as "gasoline will never exceed $1.00/gallon" (Nixon), and "the United States will never again import as much oil as it did in 1977" (Carter), but no comprehensive long-term energy policy has been proposed, although there has been concern over this failure.
Wankel engine
The Wankel engine is a type of internal combustion engine using an eccentric rotary design to convert pressure into rotating motion. In contrast to the more common reciprocating piston designs, the Wankel engine delivers advantages of simplicity, smoothness, compactness, high revolutions per minute, and a high power-to-weight ratio primarily because three power pulses per rotor revolution are produced compared to one per revolution in a two-stroke piston engine and one per two revolutions in a four-stroke piston engine, although at the actual output shaft, there is only one power pulse per revolution.
