The Alan was a German "inflation-period" automobile of simple design; it was manufactured by J Mayer in Bamberg in limited numbers between 1923 and 1925. The only model, the 6/30, had a 30hp, four-cylinder engine with overhead valves, made in Berlin by Siemens and Halske.
A car is a wheeled, self-powered motor vehicle used for transportation and a product of the automotive industry. Most definitions of the term specify that cars are designed to run primarily on roads, to have seating for one to eight people, to typically have four wheels with tyres, and to be constructed principally for the transport of people rather than goods. The year 1886 is regarded as the birth year of the modern car. In that year, German inventor Karl Benz built the Benz Patent-Motorwagen. Cars did not become widely available until the early 20th century. One of the first cars that was accessible to the masses was the 1908 Model T, an American car manufactured by the Ford Motor Company. Cars were rapidly adopted in the United States of America, where they replaced animal-drawn carriages and carts, but took much longer to be accepted in Western Europe and other parts of the world.
Cars are equipped with controls used for driving, parking, passenger comfort and safety, and controlling a variety of lights. Over the decades, additional features and controls have been added to vehicles, making them progressively more complex. Examples include rear reversing cameras, air conditioning, navigation systems, and in car entertainment. Most cars in use in the 2010s are propelled by an internal combustion engine, fueled by deflagration of gasoline (also known as petrol) or diesel. Both fuels cause air pollution and are also blamed for contributing to climate change and global warming. Vehicles using alternative fuels such as ethanol flexible-fuel vehicles and natural gas vehicles are also gaining popularity in some countries. Electric cars, which were invented early in the history of the car, began to become commercially available in 2008.
An automobile or car is a kind of wheeled motor vehicle. Automobile may also refer to:

Since the premiere of the children's television program Sesame Street on November 10, 1969, it has included what writer Malcolm Gladwell has called "the essence of Sesame Street—the artful blend of fluffy monsters and earnest adults". The original cast, chosen by producer Jon Stone, consisted of four human actors—Matt Robinson, who played Gordon; Loretta Long, who played Gordon's wife, Susan; Will Lee, who played Mr. Hooper; and Bob McGrath, who played Bob. Unlike most children's television programs at the time, the producers of Sesame Street decided against using a single host and cast a group of ethnically diverse actors, with, as Sesame Street researcher Gerald S. Lesser put it, "a variety of distinctive and reliable personalities".
Stone did not audition actors until spring 1969, a few weeks before five shows, designed to test the show's appeal to children and to examine their comprehension of the material, were due to be filmed. Stone videotaped the auditions, and researcher Ed Palmer took them out into the field to test children's reactions. The actors who received the "most enthusiastic thumbs up" were cast. For example, when the children saw Long's audition, they stood up and sang along with her rendition of "I'm a Little Teapot". As Stone said, casting was the only aspect of the show that was "just completely haphazard". Most of the cast and crew found jobs on Sesame Street through personal relationships with Stone and the other producers.
Davy is a small lunar crater that is located on the eastern edge of the Mare Nubium. It overlies the lava-flooded remains of the satellite crater Davy Y to the east, a formation which contains a crater chain designated Catena Davy. To the southeast of Davy is the prominent crater Alphonsus.
The outer rim of Davy is low, and the interior has been partly resurfaced. The perimeter is somewhat polygonal in shape, especially in the western half, and the southeast rim has been overlain by Davy A. The latter is bowl-shaped with a notch in the northern rim. The interior of Davy lacks a central peak, although there are some low central mounds and the rim of Davy Y forms a low ridge leading from the northern outer rim.
This linear string of 23 tiny craters runs from the midpoint of Davy Y towards the walled basin Ptolemaeus, following a slightly curving course to the east-northeast. It is located at selenographic coordinates 11.0° S, 7.0° W, and has a diameter of 50 km.
This formation is not believed to be due to secondary cratering because it is not radial to a suitable source crater. The most likely cause is believed to be due to a single body that broke apart prior to impact due to tidal effects. High resolution images have demonstrated that the craters formed at about the same time since the ejecta from each crater does not overlay neighboring craters. However, there are still some scientists who believe that this chain of craters may be volcanic in origin.
