Jetboard
A jetboard is a motorized surfboard, where the rider controls the speed using a handheld remote control (wireless ot tethered) and uses the bodyweight transfer to maneuver the board. The driveline typically consists of a water jet module (similar to what is found in a PWC), and either a combustion engine or a battery powered electrical motor. Use Jetboards remove the difficulties of conventional surfboards as they can be ridden without wind or waves. There is also no need for paddling, as the boards can be ridden at the touch of a button. Compared to traditional surfing, jetboarding can be easily learned and allows the user to become proficient in a short time. This makes this water sport suitable for a large audience of different physical conditions, ages, experience levels and riding styles. In addition, jetboarding can take place on lakes, rivers, canals, seas and oceans alike, making it further accessible to larger groups of people. In addition to private ownership, rental ...

Surfjet
In hydroflight sports, a jetboard is a device that uses water propulsion as its means of flying above the surface of any body of water. In jetboarding, the athlete is standing in wakeboard Wakeboarding is a water sport in which the rider, standing on a wakeboard (a board with foot bindings), is towed behind a motorboat across its wake and especially up off the crest in order to perform aerial maneuvers. A hallmark of wakeboardin ...-style boots/bindings which are attached to a board or independent base plates with jets extending downward from under the feet. The aim in jetboarding is to perform tricks such as dolphin dives, spins and backflips (even multiples), and combinations of two or more tricks. Competitive jetboarding began in 2012 with the first Flyboard World Cup, a freestyle trick jetboard competition in which athletes are critiqued by a panel of judges. The world's first open competitive event for hydroflight jetboards, Session One, was held at LTS Training school i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Personal Watercraft
A personal watercraft (PWC), also called water scooter or jet ski, is a recreational watercraft that a rider sits or stands on, not within, as in a boat. PWCs have two style categories, first and most popular being a runabout or "sit down" where the rider uses the watercraft mainly sitting down, and the watercraft typically holds two or more people. The second style is a "stand-up", where the rider uses the watercraft standing up. The stand-up styles are built for one rider and are used more for doing tricks, racing, and use in competitions. Both styles have an inboard engine driving a pump-jet that has a screw-shaped impeller to create thrust for propulsion and steering. Most are designed for two or three people, though four-passenger models exist. Many of today's models are built for more extended use and have the fuel capacity to make long cruises, in some cases even beyond 100 miles (161 km). Personal watercraft are often referred by the trademarked brand names of per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Sports
Water (chemical formula ) is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, despite not providing food, energy or organic micronutrients. Its chemical formula, H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. "Water" is also the name of the liquid state of H2O at standard temperature and pressure. A number of natural states of water exist. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds consist of suspended droplets of water and ice, its solid state. When finely divided, crystalline ice may precipitate in the form of snow. The gaseous state of water is steam or water vapor. Water covers ab ...

DC Motor
A DC motor is any of a class of rotary electrical motors that converts direct current (DC) electrical energy into mechanical energy. The most common types rely on the forces produced by induced magnetic fields due to flowing current in the coil. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current in part of the motor. DC motors were the first form of motors widely used, as they could be powered from existing direct-current lighting power distribution systems. A DC motor's speed can be controlled over a wide range, using either a variable supply voltage or by changing the strength of current in its field windings. Small DC motors are used in tools, toys, and appliances. The universal motor, a lightweight brushed motor used for portable power tools and appliances can operate on direct current and alternating current. Larger DC motors are currently used in propulsion of electric vehicle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lithium-ion Battery
A lithium-ion or Li-ion battery is a type of rechargeable battery which uses the reversible reduction of lithium ions to store energy. It is the predominant battery type used in portable consumer electronics and electric vehicles. It also sees significant use for grid-scale energy storage and military and aerospace applications. Compared to other rechargeable battery technologies, Li-ion batteries have high energy densities, low self-discharge, and no memory effect (although a small memory effect reported in LFP cells has been traced to poorly made cells). Chemistry, performance, cost and safety characteristics vary across types of lithium-ion batteries. Most commercial Li-ion cells use intercalation compounds as the active materials. The anode or negative electrode is usually graphite, although silicon-carbon is also being increasingly used. Cells can be manufactured to prioritize either energy or power density. Handheld electronics mostly use lithium polymer batteries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Czech Republic
The Czech Republic, or simply Czechia, is a landlocked country in Central Europe. Historically known as Bohemia, it is bordered by Austria to the south, Germany to the west, Poland to the northeast, and Slovakia to the southeast. The Czech Republic has a hilly landscape that covers an area of with a mostly temperate continental and oceanic climate. The capital and largest city is Prague; other major cities and urban areas include Brno, Ostrava, Plzeň and Liberec. The Duchy of Bohemia was founded in the late 9th century under Great Moravia. It was formally recognized as an Imperial State of the Holy Roman Empire in 1002 and became a kingdom in 1198. Following the Battle of Mohács in 1526, the whole Crown of Bohemia was gradually integrated into the Habsburg monarchy. The Protestant Bohemian Revolt led to the Thirty Years' War. After the Battle of White Mountain, the Habsburgs consolidated their rule. With the dissolution of the Holy Empire in 1806, the Cro ...

Electric Skateboard
An electric skateboard is a personal transporter based on a skateboard. The speed is usually controlled by a wireless hand-held throttle remote or rider body weight-shifting between front of the board for forward motion and rear for braking. As for the direction of travel to the right or left, it is adjusted by tilting the board to one side or the other. The classification of electric skateboards (e.g. whether they qualify as a 'vehicle') and legality of their use on roads or pavements varies between countries. History Early incarnations The MotoBoard, which was gasoline-powered, was released in the summer of 1975 but was banned in California in 1997 due to noise and pollution. Modern electric devices Louie Finkle of Seal Beach, California is often cited as an originator of the modern electric skateboard, offering his first wireless electric skateboard in 1997 and a patent filed in April 1999, however it was not until the 2004–2006 that electric motors and batteries were avail ...
