Kite Skating
Kite skating, sometimes referred to as Kiteblading, is a land-based extreme sport that uses powerful and controllable kite A kite is a tethered heavier than air flight, heavier-than-air craft with wing surfaces that react against the air to create Lift (force), lift and Drag (physics), drag forces. A kite consists of wings, tethers and anchors. Kites often have ...s to propel riders of inline skates or off-road skates. They can reach speeds up to 60+ mph across parking lots, desert dry lakes, grassy fields, and sandy beaches. Four-line, steerable para-foil kites are used as the power source. Typically used in rough terrain, kite skates use large pneumatic tires (8 to 12 inch diameter). Similar to Kite ice skating.

Kite
A kite is a tethered heavier than air flight, heavier-than-air craft with wing surfaces that react against the air to create Lift (force), lift and Drag (physics), drag forces. A kite consists of wings, tethers and anchors. Kites often have a bridle and tail to guide the face of the kite so the wind can lift it. Some kite designs do not need a bridle; box kites can have a single attachment point. A kite may have fixed or moving anchors that can balance the kite. The name is derived from the kite (bird), kite, the hovering bird of prey. There are several shapes of kites. The Lift (force), lift that sustains the kite in flight is generated when air moves around the kite's surface, producing low pressure above and high pressure below the wings. The interaction with the wind also generates horizontal Drag (physics), drag along the direction of the wind. The resultant force vector from the lift and drag force components is opposed by the tension of one or more of the rope, lines ...

Kite Ice Skating
Kite ice skating, sometimes referred to as ice kiting, ice kite skating, para-skating or para ice skating, is a sport practised on ice skates using a large controllable kite to propel across frozen rivers, frozen lakes and other frozen surfaces. In gusty conditions, speed must be controlled by raising the kite in the air parallel to the ice, or moving it in the opposite direction to the direction of riding to slow down. Kite ice skaters often perform tricks and invent new ones, for example, "Double around the world". Safety considerations With a traditional diamond-shaped kite skaters can travel faster than wind speed by angling the kite, similarly to the method used in sailing to trim a boat's course and sails for greater speed. It is possible to quickly exceed safe speeds, exhausting the skater's legs from absorbing the shock of bumpy ice, and becoming susceptible to crashes. A helmet, elbow, and knee protection are strongly advised. Care should be taken not to ride over the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Popular Science
Popular science (also called pop-science or popsci) is an interpretation of science intended for a general audience. While science journalism focuses on recent scientific developments, popular science is more broad ranging. It may be written by professional science journalists or by scientists themselves. It is presented in many forms, including books, film and television documentaries, magazine articles, and web pages. History Before the modern specialization and professionalization of science, there was often little distinction between "science" and "popular science", and works intended to share scientific knowledge with a general reader existed as far back as Greek and Roman antiquity. Without these popular works, much of the scientific knowledge of the era might have been lost. For example, none of the original works of the Greek astronomer Eudoxus (4th century BC) have survived, but his contributions were largely preserved due to the didactic poem '' Phenomena'' writte ...

Inline Skating
Inline skating is a multi-disciplinary sport and can refer to a number of activities practiced using inline skates. Inline skates typically have two to five polyurethane wheels depending on the style of practice, arranged in a single line by a metal or plastic frame on the underside of a boot. The in-line design allows for greater speed and maneuverability than traditional (or "quad") roller skates. Following this basic design principle, inline skates can be modified to varying degrees to accommodate niche disciplines. Inline skating is commonly referred to as ''rollerblading'', or just ''blading'', due to the popular brand of inline skates, Rollerblade. History of skating An inline skate appeared in a Paris patent in 1819, but were overtaken in popularity by quad skates. The German branch of SKF developed and produced inline skates in 1978 with wheels designed for hockey rinks and streets. The product was discontinued after one year as the management did not want a consu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
