A safety bicycle is a type of bicycle that became very popular beginning in the late 1880s as an alternative to the penny-farthing or ordinary and is now the most common type of bicycle. Early bicycles of this style were known as safety bicycles because they were noted for, and marketed as, being safer than the high wheelers they were replacing.Even though modern bicy.. Read More..
Motorcycle history begins in the second half of the 19th century. Motorcycles are descended from the "safety bicycle," a bicycle with front and rear wheels of the same size and a pedal crank mechanism to drive the rear wheel.Despite some early landmarks in its development, motorcycles lack a rigid pedigree that can be traced back to a single idea or machine. Instead, .. Read More..
In 1815 the Tambora volcano in indonesia erupted,starting a chain of events that led to the invention of the bicycle.The eruption was the largest in recorded history and dumped tons of ash into Earth's atmosphere.This caused the global themperature to drop,and did terrible things to crops.Three years earlier,following some bad weather in 1812,the price of oats was..

Ginger came out .. Read More..
A jetboat is a boat propelled by a jet of water ejected from the back of the craft. Unlike a powerboat or motorboat that uses a propeller in the water below or behind the boat, a jetboat draws the water from under the boat into a pump inside the boat, then expels it through a nozzle at the stern.Jetboats were originally designed by Sir William Hamilton (who developed ..

An escalator is a moving staircase – a conveyor transport device for carrying people between floors of a building. The device consists of a motor-driven chain of individual, linked steps that move up or down on tracks, allowing the step treads to remain horizontal.An escalator is a conveyor type transport device that moves people. It is a moving staircase with steps.. Read More..
An elevator is a type of vertical transport equipment that efficiently moves people or goods between floors (levels, decks) of a building, vessel, or other structure. Elevators are generally powered by electric motors that either drive traction cables or counterweight systems like a hoist, or pump hydraulic fluid to raise a cylindrical piston like a jack.Although elev..

A rack railway is a steep grade railway with a toothed rack rail, usually between the running rails. The trains are fitted with one or more cog wheels or pinions that mesh with this rack rail. This allows the trains to operate on steep grades above 7%, which is the maximum for friction-based rail. Most rack railways are mountain railways, although a few are transit ra.. Read More..
Vespa is an Italian brand of scooter manufactured by Piaggio. 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.D'Ascanio designed the first production helicopter, for Agusta, and designed the first motor scooter fo..

A snowmobile is a vehicle designed for winter travel and recreation on snow. It is designed to be operated on snow and ice and does not require a road or trail but most are driven on open terrain or trails.In 1935, Bombardier assembled a vehicle that ran on caterpillar tracks similar to a tank’s. The first snowmobile, the vehicle was steered by skis and could hold t.. Read More..
The Caspian Sea Monster also known as the "Kaspian Monster", was an experimental ekranoplan, developed at the design bureau of Rostislav Alexeyev.HistoryThe KM was designed in 1964 – 1965, and was unique in size and payload. The first spy photographs from American spy satellites showed a strange aircraft carrying letters "KM" on its fuselage. CIA disambiguated it as.. Read More..
A steam locomotive is a railway locomotive that produces its pulling power through a steam engine. These locomotives are fueled by burning combustible material—usually coal, wood, or oil—to produce steam in a boiler. The steam moves reciprocating pistons which are mechanically connected to the locomotive's main wheels (Drivers). Both fuel and water supplies ar.. Read More..
The RT-23 (NATO reporting name SS-24 Scalpel) was a Soviet ICBM developed and produced by the Yuzhnoye Design Bureau before 1991. It is cold-launched, and comes in silo– and railway-car–based variants. It is a three-stage missile that uses solid fuel and thrust vectoring for the first stage, with 10 MIRV warheads, each with a 550–kt yield.The missile was the cul.. Read More..
The first successful rack railway in the US was the Mount Washington Cog Railway, developed by Sylvester Marsh.While ascending Mount Washington in 1852, he lost his way, and then conceived the idea of building a railroad to its summit, believing that such an enterprise could be made profitable. He obtained a charter for the road on 25 June 1858, but the American Civil.. Read More..
A gyrocar is a two-wheeled automobile. The difference between a bicycle or motorcycle and a gyrocar is that in a bike, dynamic balance is provided by the rider, and in some cases by the geometry and mass distribution of the bike itself, and the gyroscopic effects from the wheels. Steering a motorcycle is done by precessing the front wheel; gyroscopic effects play a ma.. Read More..
Land sailing, also known as sand yachting or land yachting, is the act of moving across land in a three-wheeled vehicle powered by wind through the use of a sail. The term comes from analogy with water sailing. Historically, land sailing was used as a mode of transportation or recreation. Since the 1950s it has evolved primarily into a racing sport.Simon StevinStevin .. Read More..

Maglev or magnetic levitation is a transport method that uses magnetic levitation to move vehicles without touching the ground. With maglev, a vehicle travels along a guideway using magnets to create both lift and propulsion, thereby reducing friction by a great extent and allowing very high speeds.In 1968, while delayed in traffic on the Throgs Neck Bridge, James Pow..

The Caprotti valve gear is a type of steam engine valve gear invented in the early 1920s by Italian architect and engineer Arturo Caprotti. It uses camshafts and poppet valves rather than the piston valves used in other valve gear. While basing his design on automotive valves, Caprotti made several significant departures from this design to adapt the valves for steam... Read More..
The deep column station is a type of subway station, consisting of a central hall with two side halls, connected by ring-like passages between a row of columns. Depending on the type of station, the rings transmit load to the columns either by "wedged arches" or through purlins, forming a "column-purlin complex".The fundamental advantage of the column station is the s..
