MS Beluga Skysails
MS ''Onego Deusto'' (christened ''Beluga SkySails'') is a commercial Containerization, container cargo ship. It is the world's first ship partially powered by a computer-controlled kite rig, called the SkySails system. It consists of a kite similar to a huge paraglider of up to area. Kite power The kite has an area of and reduces fuel consumption by 15–20% on average; it was set to be upgraded to in order to increase fuel savings by about 30%. Stephan Wrage, managing director of SkySails GmbH – which installed the kite – announced: "During the next few months we will finally be able to prove that our technology works in practice and significantly reduces fuel consumption and emissions." Verena Frank, project manager at Beluga Shipping GmbH, SkySails GmbH's partner, further stated that "the project's core concept was using wind energy as auxiliary propulsion power and using wind as a free of charge energy". This kite is connected to the ship by a cable, and controlled by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kite Applications
Different types of flying kites (such as water kites, bi-media kites, fluid kites, gas kites, kytoons, Paravane (water kite), paravanes, soil kites, solid kites, and plasma kites) have niche applications. In nature, some animals, such as spiders, also make use of Ballooning (spider), kiting. Aerial photography File:PicEddyKite.jpg, William Abner Eddy patented a kite.

Kite Rig
Kite rigs are wind-assisted propulsion systems for propelling a vehicle. They differ from conventional sails in that they are flown from kite control lines, not supported by masts. Vehicles driven by kites include boats, buggies, and vehicles with snow and ice runners. They may be as simple as a person flying a kite while standing on a specialized skateboard, or be large, complex systems fixed to the vehicle, with powered and automated controls. They have recreational and commercial uses. Structure Current kite rigs can be sailed within 50 degrees of the wind.Skysails Captain John Konrad, Mariner's Weather Log, April 2009, Volume 53, No. 1, This allows them to s ...

Marine Propulsion
Marine propulsion is the mechanism or system used to generate thrust to move a watercraft through water. While paddles and sails are still used on some smaller boats, most modern ships are propelled by mechanical systems consisting of an electric motor or internal combustion engine driving a propeller, or less frequently, in pump-jets, an impeller. Marine engineering is the discipline concerned with the engineering design process of marine propulsion systems. Human-powered watercraft, Human-powered paddles and oars, and later, sails were the first forms of marine propulsion. Rowed galleys, some equipped with sail, played an important early role in early human seafaring and naval warfare, warfare. The first advanced mechanical means of marine propulsion was the marine steam engine, introduced in the early 19th century. During the 20th century it was replaced by two-stroke diesel engine, two-stroke or four-stroke diesel engines, outboard motors, and gas turbine engines on faster sh ...

Kitesurfing
Kiteboarding or kitesurfing is a sport that involves using wind power with a large power kite to pull a rider across a water, land, snow, sand, or other surface. It combines the aspects of paragliding, surfing, windsurfing, skateboarding, snowboarding, and wakeboarding. Kiteboarding is among the less expensive and more convenient sailing sports. After some concepts and designs that emerged in the late 1970s and early 1980s were successfully tested, the sport received a wider audience in the late 1990s and became mainstream at the turn of the century. It has freestyle, wave-riding, and racing competitions. The sport held the speed sailing record, reaching before being eclipsed by the Vestas Sailrocket. Worldwide, there are 1.5 million kitesurfers, while the industry sells around 100,000 to 150,000 kites per year. Most power kites are leading edge inflatable kite, leading-edge inflatable kites or foil kites attached by about of flying lines to a control bar and a harn ...

Kite Control Lines
Kite types, kite mooring, and kite applications result in a variety of kite control systems. Contemporary manufacturers, kite athletes, kite pilots, scientists, and engineers are expanding the possibilities. Kite control systems encompass a range of methods and technologies used for maneuvering and stabilizing kites in various applications. These systems have evolved from simple manual controls, to intricate automated and powered configurations, reflecting the spectrum of kite uses from recreational activities, to scientific research and energy generation. The development and refinement of these control systems have significantly expanded the capabilities and applications of kites, sometimes changing them from traditional leisure objects, into tools for modern-day purposes. High-altitude kite control systems, especially notable in record-setting flights, incorporate advanced mechanisms such as on-board angle-of-attack adjusters. These systems are designed to manage kite line tens ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airborne Wind Energy
Airborne wind energy (AWE) is the direct use or generation of wind energy by the use of aerodynamic or aerostatic lift devices. AWE technology is able to harvest high altitude winds, in contrast to wind turbines, which use a rotor mounted on a tower. The term high-altitude wind power (HAWP) has been used to refer to AWE systems. However, semantically HAWP might also include wind energy conversion systems that are somehow positioned at a large height from the ground or sea surface. Various mechanisms are proposed for capturing the kinetic energy of winds such as kites, kytoons, aerostats, gliders, gliders with turbines for regenerative soaring, sailplanes with turbines, or other airfoils, including multiple-point building- or terrain-enabled holdings. Once the mechanical energy is derived from the wind's kinetic energy, then many options are available for using that mechanical energy: direct traction, conversion to electricity aloft or at ground station, conversion to laser or m ...

Hybrid Vehicle
A hybrid vehicle is one that uses two or more distinct types of power, such as submarines that use diesel when surfaced and batteries when submerged. Other means to store energy include pressurized fluid in hydraulic hybrids. Hybrid powertrains are designed to switch from one power source to another to maximize both fuel efficiency and energy efficiency. In hybrid electric vehicles, for instance, the electric motor is more efficient at producing torque, or turning power, while the combustion engine is better for maintaining high speed. Improved efficiency, lower emissions, and reduced running costs relative to non-hybrid vehicles are three primary benefits of hybridization. Vehicle types Two-wheeled and cycle-type vehicles Mopeds, electric bicycles, and even electric kick scooters are a simple form of a hybrid, powered by an internal combustion engine or electric motor and the rider's muscles. Early prototype motorcycles in the late 19th century used the same principle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sail
A sail is a tensile structure, which is made from fabric or other membrane materials, that uses wind power to propel sailing craft, including sailing ships, sailboats, windsurfers, ice boats, and even sail-powered land vehicles. Sails may be made from a combination of woven materials—including canvas or polyester cloth, laminated membranes or bonded filaments, usually in a three- or four-sided shape. A sail provides propulsive force via a combination of lift and drag, depending on its angle of attack, its angle with respect to the apparent wind. Apparent wind is the air velocity experienced on the moving craft and is the combined effect of the true wind velocity with the velocity of the sailing craft. Angle of attack is often constrained by the sailing craft's orientation to the wind or point of sail. On points of sail where it is possible to align the leading edge of the sail with the apparent wind, the sail may act as an airfoil, generating propulsive force as air pa ...
