Carl-Georg Rasmussen
Carl Georg Rasmussen is a mechanical engineer with a PhD in physics; an ecologist specializing in noise pollution; and a light aircraft pilot. He is the designer and manufacturer of the Leitra velomobile. Velomobiles were produced in the 1930s, but commercial production ended after the second world war. Rasmussen's Leitra, or "light individual transportation", was motivated by the oil crisis; it is the first commercial production velomobile using "modern" materials and designs. Rasmussen was interested in daily transport and tours, which guided his design choices for the Leitra. He last owned a car in the 1980s. Rasmussen had an early Leitra confiscated in 1982 by Danish police as a dangerous vehicle; this led him get legal status of velomobiles in Denmark. Rasmussen also organizes velomobile tours. Rasmussen rode a Leitra in the 1987 Paris–Brest–Paris (PBP). Although the Mochet Velocar is French, Rasmussen is probably the first PBP velomobile rider. In order to increas ...

Ecologist
Ecology () is the study of the relationships between living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere level. Ecology overlaps with the closely related sciences of biogeography, evolutionary biology, genetics, ethology, and natural history. Ecology is a branch of biology, and it is not synonymous with environmentalism. Among other things, ecology is the study of: * The abundance, biomass, and distribution of organisms in the context of the environment * Life processes, antifragility, interactions, and adaptations * The movement of materials and energy through living communities * The successional development of ecosystems * Cooperation, competition, and predation within and between species * Patterns of biodiversity and its effect on ecosystem processes Ecology has practical applications in conservation biology, wetland management, natural resource managemen ...

Noise Pollution
Noise pollution, also known as environmental noise or sound pollution, is the propagation of noise with ranging impacts on the activity of human or animal life, most of them are harmful to a degree. The source of outdoor noise worldwide is mainly caused by machines, transport, and propagation systems.Senate Public Works Committee. ''Noise Pollution and Abatement Act of 1972''. S. Rep. No. 1160, 92nd Congress. 2nd session Poor urban planning may give rise to noise disintegration or pollution, side-by-side industrial and residential buildings can result in noise pollution in the residential areas. Some of the main sources of noise in residential areas include loud music, transportation (traffic, rail, airplanes, etc.), lawn care maintenance, construction, electrical generators, wind turbines, explosions, and people. Documented problems associated with noise in urban environments go back as far as ancient Rome. Research suggests that noise pollution in the United States is the high ...

Light Aircraft
A light aircraft is an aircraft that has a maximum gross takeoff weight of or less.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 308. Aviation Supplies & Academics, 1997. Light aircraft are used as utility aircraft commercially for passenger and freight transport, sightseeing, photography, and other roles, as well as personal use. Examples of aircraft that are at the maximum gross takeoff weight for this category include the de Havilland Canada DHC-6 Twin Otter and Beechcraft B200 Super King Air. Uses Uses include aerial surveying, such as monitoring pipelines, light cargo operations, such as "feeding" cargo hubs, and passenger operations. Light aircraft are used for marketing purposes, such as banner towing and skywriting, and flight instruction. The majority of personal aircraft are light aircraft, the most popular in history being the Cessna 172, and most popular in modern history being the Cirrus SR22 and Robinson R44. Larger light aircraft, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leitra
Leitra is a Danish company and also the name of the velomobile it produces. In Sweden designs for a two-person, four-wheeled velomobile called the Fantom were sold as blueprints in the 1930s and 40s. Many thousands of sets of DIY instructions were sold, but very few vehicles were actually built. The body was made of plywood. The oil shock of 1978-9 inspired Carl Georg Rasmussen, a Danish engineer and pilot, to design and build the first practical velomobile. A tadpole recumbent tricycle with full glass-fiber fairing, it was dubbed the Leitra (''Danish Danish may refer to: * Something of, from, or related to the country of Denmark People * A national or citizen of Denmark, also called a "Dane," see Demographics of Denmark * Culture of Denmark * Danish people or Danes, people with a Danish a ...'': Let individuel transport, meaning "light individual transport"). About the company Carl Georg Rasmussen initially formed the company as a limited partnership with ten investors ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Velomobile
A velomobile (); velomobiel, velo, or bicycle car is a human-powered vehicle (HPV) enclosed for aerodynamic advantage and/or protection from weather and collisions. Velomobiles are similar to recumbent bicycles, pedal go-karts and tricycles, but with a full fairing (aerodynamic or weather protective shell) and are not to be confused with purpose-built mobiles for racing or speed records fully faired vehicles with two wheels, generally called streamliners. Streamliners have set many speed and distance records. Though fast in their own right, velomobiles are considered much more suitable for the street than two-wheeled streamliners. Using three or more wheels can have advantages for everyday use, including the ability to stop and start unaided, better stability, cross-wind handling, etc., though there are arguments made that the multiple track machines (three or more wheels) have aerodynamic disadvantages due to the drag of the extra wheels and the surface contact points.

Danish Police
The Police of Denmark ( da, Politiet, fo, Løgreglan, kl, Politiit) is the Danish National Police force, and the interior part of the Danish security forces (the Danish military being the exterior) in the Kingdom ( The Danish Realm: Denmark (proper), Greenland, Faroe Islands). The police are empowered to enforce the law and to effect public and social order, as well as being responsible for border control. Organization The police of Denmark consists of 12 districts each managed by a director and two minor districts in Greenland and the Faroe Islands, run by a local chief of police. The district of Copenhagen is somewhat differently organized due to its size and tasks. Besides the regular districts other organizations exist that work outside the general police: * Rigspolitiet - a nationwide police force with specialized tasks such as ''Budgets and Accounts'', ''Building Surveying Department'' and the ''Data Investigating Department'' * Politiets Efterretningstjeneste - th ...

Paris–Brest–Paris
Paris–Brest–Paris (PBP) is a long-distance cycling event. It was originally a 1,200 km () bicycle race from Paris to Brest and back to Paris in 1891. The last time it was run as a race was 1951. The most recent edition of PBP was held on 18–22 August 2019. In 1931 amateur cyclists were separated from professionals. There are two independent long distance bicycle tours. One is the ''brevet'' (also called ''randonnée''), in which cyclists ride individually. The goal is to make it within 90 hours, but with no competition. This is held every four years. The other is an '' audax'' where cyclists ride in a group, held every five years. So in 1931 there were three independent cycling events, sharing the same route. The ''audax'' is organised by the Union des Audax Françaises, while the ''brevet'' is organised by the Audax Club Parisien. The ''brevet'' As in all ''brevet'' events, there is emphasis on self-sufficiency. Riders buy supplies anywhere along the course, but supp ...

Velocar
Velocar was the name given to velomobiles made in the 1930s and 1940s by Mochet et Cie of Puteaux, France and colloquially to the company's recumbent bicycles. was the inventive maker of lightweight powered cyclecars (Le P'tit Auto) and pedal-powered cars (quadricycles), mainly two-seaters, built on a tubular-steel chassis with bicycle-sized wheels, variable gears, and aerodynamic bodywork, in effect a faired-in "sociable". The popularity of the little cars declined in the late 1930s as cheaper, powered cars became available, only to rise rapidly when petrol became almost unobtainable during World War II, 1939–1945. However, Mochet's stroke of genius was to make what was the first performance recumbent bicycle, or ''vélo couché'', using a design that was based on half of his four-wheeled Velocar. This machine, called by the factory the "Velo-Velocar", or "V-V" for short, broke many world cycling records in 1933. Although Mochet had verified with the UCI and the UVF that ...

Year Of Birth Missing (living People)
A year or annus is the orbital period of a planetary body, for example, the Earth, moving in its orbit around the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by change in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons are generally recognized: spring, summer, autumn and winter. In tropical and subtropical regions, several geographical sectors do not present defined seasons; but in the seasonal tropics, the annual wet and dry seasons are recognized and tracked. A calendar year is an approximation of the number of days of the Earth's orbital period, as counted in a given calendar. The Gregorian calendar, or modern calendar, presents its calendar year to be either a common year of 365 days or a leap year of 366 days, as do the Julian calendars. For the Gregorian calendar, the average length of the calendar year (the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
