Pedalo IMG 2877
A pedalo (British English) or paddle boat (U.S., Canadian, and Australian English) is a human-powered watercraft propelled by the action of pedals turning a paddle wheel. Description A pedalo is a human-powered watercraft propelled by the turning of a paddle wheel. The wheel is turned by people of rotating the wiktionary:Pedal, pedals of the craft. The paddle wheel of a pedalo is a smaller version of that used by a paddle steamer. Use Pedalos, being particularly suited to calm waters, are often hired out for use on ponds and small lakes in urban parks. Designs The earliest record of a pedalo is perhaps Leonardo da Vinci's diagram of a craft driven by two pedals. Typically, a two-seat pedalo has two sets of pedals side-by-side, designed to be used together. Some models, however, have three pedals on each side, to allow a person boating alone to pedal from a centrally seated position.

Paddle Steamer
A paddle steamer is a steamship or steamboat powered by a steam engine that drives paddle wheels to propel the craft through the water. In antiquity, paddle wheelers followed the development of poles, oars and sails, where the first uses were wheelers driven by animals or humans. In the early 19th century, paddle wheels were the predominant way of propulsion for steam-powered boats. In the late 19th century, paddle propulsion was largely superseded by the screw propeller and other marine propulsion systems that have a higher efficiency, especially in rough or open water. Paddle wheels continue to be used by small, pedal-powered paddle boats and by some ships that operate tourist voyages. The latter are often powered by diesel engines. Paddle wheels The paddle wheel is a large steel framework wheel. The outer edge of the wheel is fitted with numerous, regularly spaced paddle blades (called floats or buckets). The bottom quarter or so of the wheel travels under water. An e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human-powered Watercraft
Human-powered watercraft are watercraft propelled by human power. The three main methods of collecting human power are directly from the hands or feet, through the hands with oars, paddles, or poles, or through the feet with pedals and a crank or treadle. While most human-powered watercraft use buoyancy to maintain their position relative to the surface of the water, a few, such as human-powered hydrofoils and human-powered submarines, use hydrofoils, either alone or in addition to buoyancy. Oared craft Oars are held at one end, have a blade on the other end, and pivot in between in oarlocks. Oared craft include: * Racing shell Using oars in pairs, with one hand on each oar, is two-oar sculling. The oars may also be called sculls. Two-oared sculled craft include: * Adirondack guideboat * Banks dory, Gloucester dory, and McKenzie River dory * Dinghy * Sampans rowed by foot in Ninh Bình Province of northern Vietnam. * Scull, Single scull, Double scull, Quad scull, and Oc ...

Boat Types
A boat is a watercraft of a large range of types and sizes, but generally smaller than a ship, which is distinguished by its larger size, shape, cargo or passenger capacity, or its ability to carry boats. Small boats are typically found on inland waterways such as rivers and lakes, or in protected coastal areas. However, some boats, such as the whaleboat, were intended for use in an offshore environment. In modern naval terms, a boat is a vessel small enough to be carried aboard a ship. Boats vary in proportion and construction methods with their intended purpose, available materials, or local traditions. Canoes have been used since prehistoric times and remain in use throughout the world for transportation, fishing, and sport. Fishing boats vary widely in style partly to match local conditions. Pleasure craft used in recreational boating include ski boats, pontoon boats, and sailboats. House boats may be used for vacationing or long-term residence. Lighters are used to conve ...

Museum Of Science And Industry (Chicago)
The Museum of Science and Industry (MSI) is a science museum located in Chicago, Illinois, in Jackson Park, in the Hyde Park neighborhood between Lake Michigan and The University of Chicago. It is housed in the former ''Palace of Fine Arts'' from the 1893 World's Columbian Exposition. Initially endowed by Julius Rosenwald, the Sears, Roebuck and Company president and philanthropist, it was supported by the Commercial Club of Chicago and opened in 1933 during the Century of Progress Exposition. Among the museum's exhibits are a full-size replica coal mine, captured during World War II, a model railroad, the command module of Apollo 8, and the first diesel-powered streamlined stainless-steel passenger train (''Pioneer Zephyr''). History The Palace of Fine Arts (also known as the Fine Arts Building) at the 1893 World's Columbian Exposition was designed by Charles B. Atwood for D. H. Burnham & Co. During the fair, the palace displayed paintings, prints, drawing, sculpture, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leonardo Da Vinci
Leonardo di ser Piero da Vinci (15 April 14522 May 1519) was an Italian polymath of the High Renaissance who was active as a painter, Drawing, draughtsman, engineer, scientist, theorist, sculptor, and architect. While his fame initially rested on his achievements as a painter, he also became known for #Journals and notes, his notebooks, in which he made drawings and notes on a variety of subjects, including anatomy, astronomy, botany, cartography, painting, and paleontology. Leonardo is widely regarded to have been a genius who epitomized the Renaissance humanism, Renaissance humanist ideal, and his List of works by Leonardo da Vinci, collective works comprise a contribution to later generations of artists matched only by that of his younger contemporary, Michelangelo. Born Legitimacy (family law), out of wedlock to a successful Civil law notary, notary and a lower-class woman in, or near, Vinci, Tuscany, Vinci, he was educated in Florence by the Italian painter and sculptor ...

Urban Park
An urban park or metropolitan park, also known as a municipal park (North America) or a public park, public open space, or municipal gardens ( UK), is a park in cities and other incorporated places that offer recreation and green space to residents of, and visitors to, the municipality. The design, operation, and maintenance is usually done by government agencies, typically on the local level, but may occasionally be contracted out to a park conservancy, "friends of" group, or private sector company. Common features of municipal parks include playgrounds, gardens, hiking, running and fitness trails or paths, bridle paths, sports fields and courts, public restrooms, boat ramps, and/or picnic facilities, depending on the budget and natural features available. Park advocates claim that having parks near urban residents, including within a 10-minute walk, provide multiple benefits. History A park is an area of open space provided for recreational use, usually owned and maintain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Paddle Wheel
A paddle wheel is a form of waterwheel or impeller in which a number of paddles are set around the periphery of the wheel. It has several uses, of which some are: * Very low-lift water pumping, such as flooding paddy fields at no more than about height above the water source. * To move and mix algae culture in the raceway ponds used for algaculture. * Propulsion of watercraft (as a paddlewheel) * Low head hydro power (as a waterwheel) * Flow sensors * Aerators The paddle wheel is an ancient invention but is still used today in a wide range of industrial and agriculture applications. Ship propulsion Paddle wheels would enable ships to travel without needing wind or oars. They were made obsolete by propellers, which had greater propulsion with lower weight and fuel usage. This was demonstrated by an 1845 tug-of-war competition between and with the screw-driven ''Rattler'' pulling the paddle steamer ''Alecto'' backward at .
