Wind turbine design
Wind turbine design is the engineering discipline covering the rotor and blades, drivetrain, tower and foundation, and controls of a machine that turns wind's kinetic energy into electricity.
Wind turbine icing
Wind turbine icing is the accumulation of ice on wind turbine blades, which reduces power output, disables sensors, and creates safety hazards; annual losses at harsh sites can reach 50%.
Wind turbine noise
Wind turbine noise is the sound emitted by operating wind turbines, produced mainly by aerodynamic interaction of the rotating blades with the air, plus smaller mechanical contributions from the drivetrain.
Wind wave
A wind wave, or ocean surface wave, is a wave on water generated by local wind blowing across the surface, as distinct from swell, tides, and seiches.
Wind-assisted propulsion
Wind-assisted propulsion uses devices such as rotor sails, wing sails, or kites to add wind thrust to a ship that keeps its engine as its main means of propulsion.
Wind-driven circulation
Wind-driven circulation is the water motion generated when wind stress acts on a lake or sea surface, organizing currents, gyres, and waves, and usually the main flow-generating mechanism in lakes.
Wind, Sand and Stars
Wind, Sand and Stars (French: Terre des hommes) is a 1939 memoir by aviator Antoine de Saint-Exupéry drawing on his airmail flights over the Sahara and Andes.
Windaria (ウインダリア)
Windaria (ウインダリア, Dōwa Meita Senshi Windaria), also Once Upon a Time, is a 1986 Kaname Productions anime film directed by Kunihiko Yuyama, written by Keisuke Fujikawa, a tragedy of war and broken promises between Paro and Itha, with Mutsumi Inomata's character designs.
Windbreak
A windbreak, also called a shelterbelt, is a linear planting of trees or shrubs that slows wind and creates a protected zone, reducing soil erosion and protecting crops and livestock.
Windbreaker
Windbreaker (British: windcheater): a lightweight, wind-resistant jacket, word dating to 1918-1924, popularized in the 1970s, descended from Inuit parkas; typically nylon with DWR, water-resistant but not waterproof, distinct from softshells and rain jackets.
Windcatcher
A windcatcher, known in Persian as badgir and in Egypt as malqaf, is a tower that channels wind into buildings for passive cooling, especially in Yazd, Iran.
Windchill
Windchill is a product lifecycle management software platform created by PTC, first released in 1998, that helps manufacturers manage product data, bills of materials, and change processes.
Windell Middlebrooks
Windell Middlebrooks (Windell Dwain Middlebrooks Jr.) was an American actor (1979–2015) from Fort Worth, Texas, known as the Miller High Life deliveryman and as Dr. Curtis Brumfield on Body of Proof, plus Kirby on The Suite Life on Deck.
Windermere
Windermere (Lake Windermere) is England's largest natural lake, a glacial twin-basin lake in the Lake District, Cumbria; 14.8 km², 64 m deep, famed for scenery, Arctic charr, and ongoing sewage and nutrient pollution disputes.
WindEurope
WindEurope, formerly the European Wind Energy Association (EWEA), is a Brussels-based non-profit trade association representing more than 600 members of the European wind energy supply chain.
Windfall (2022 film)
Windfall (2022) is a Netflix crime thriller directed by Charlie McDowell, starring Jason Segel, Lily Collins, and Jesse Plemons as an intruder and wealthy couple trapped in an Ojai vacation home; released March 18, 2022.
WindFloat
WindFloat is a three-column semi-submersible floating foundation for offshore wind turbines, developed by Principle Power and first deployed off Aguçadoura, Portugal, in 2011, later used at WindFloat Atlantic and Kincardine.
Windhand
Windhand is a doom metal band from Richmond, Virginia, formed in 2009, on Relapse Records. Albums: Windhand (2012), Soma (2013), Grief's Infernal Flower (2015), Eternal Return (2018); fronted by vocalist Dorthia Cottrell.
Windhoek
Windhoek is the capital and largest city of Namibia, in the central highlands at about 1,650 m. Known for the 1890 Alte Feste fort, Katutura's history, and pioneering direct potable wastewater reuse since 1968.
Winding number
The winding number, also called the index, counts the net number of times a closed curve travels around a point, positive for counterclockwise and negative for clockwise turns.
Windland Smith Rice
Windland Smith Rice (Sandra Windland "Wendy" Smith Rice, 1970-2005) was an American nature photographer for National Geographic and Nature's Best Photography; the Windland Smith Rice International Awards are named for her and her family endowed the Smithsonian program.
Windlass
A windlass is a hauling and lifting machine with a horizontal drum turned by a crank or motor, around which a rope or chain winds to raise a load.
Windmill
A windmill is a machine that converts wind energy into rotational mechanical power, traditionally with sails, for grinding grain, pumping water, and crushing materials; its modern descendant is the wind turbine.
Windmill Hill
Windmill Hill, a hill north-west of Avebury in Wiltshire, England, is topped by the largest known Neolithic causewayed enclosure in Britain, which gave its name to the Windmill Hill culture.
Windmill scene

Window
A window is a building component of a frame and one or more panes of glazing, fitted into a wall or roof opening to admit light and often air.
Window air conditioner
A window air conditioner is a self-contained room cooling unit that mounts in a window opening and expels heat outdoors, with compressor, condenser, evaporator, and fan in one chassis.
Window blind
A window blind, also called a window shade or sun blind, is a covering of slats or fabric panels that raise, lower, or tilt to control a room's light and privacy.
Window film
Window film, also called window tint, is a thin polyester laminate applied to glass in homes, commercial buildings, and vehicles to cut solar heat, glare, and UV, and improve privacy.
Window function
A window function, also called a tapering or apodization function, weights a finite signal segment before Fourier analysis, reducing spectral leakage at the cost of frequency resolution.
