List of New Zealand national cricket captains: This is a complete list of all of New Zealand's national cricket captains at official international level.  As such it includes details of all the men who have captained at least one Test match or One Day International, all boys who have captained in at least one Youth Test or Youth ODI, and all women who have captained at least one women's Test match or women's one-day international.  New Zealand became a full member of the Imperial Cricket Conference (now the International Cricket Council) on 31 May 1926 at the same time as India were made up to full membership, and their first-class cricket matches against other full member nations since that date have been Tests.

Spiral tube water wheel: A spiral tube water wheel is a method of pumping water by using an undershot water wheel which has a scoop connected to a spiral tube.  As the wheel turns the scoop will alternatively introduce either water or air into the spiral tube.  The pressure generated from the column of water introduced by the scoop is added to the pressure from previous scoops and so as the wheel turns it will increase the water pressure with every turn of the spiral.  These wheels have only one moving part and have been known to pump water with no maintenance for several years.

Ball detent: A ball detent is a simple mechanical arrangement used to hold a moving part in a temporarily fixed position relative to another part.  Usually the moving parts slide with respect to each other, or one part rotates within the other.

Hitbox: A hitbox is an invisible shape commonly used in video games for real-time collision detection.  It is often a rectangle (in 2D games) or cuboid (in 3D) that is attached to and follows a point on a visible object (such as a model or a sprite), though circular or spheroidial shapes are also common.  It is common for animated objects to have a set of hitboxes attached to one moving part each to ensure accuracy during motion.

Turbine: A turbine (from the Latin "turbo", a vortex, related to the Greek τύρβη , "tyrbē", meaning "turbulence") is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work.  The work produced by a turbine can be used for generating electrical power when combined with a generator or producing thrust, as in the case of jet engines.  A turbine is a turbomachine with at least one moving part called a rotor assembly, which is a shaft or drum with blades attached.  Moving fluid acts on the blades so that they move and impart rotational energy to the rotor.  Early turbine examples are windmills and waterwheels.

Gate: A gate or gateway is a point of entry to a space which is enclosed by walls. Gates may prevent or control the entry or exit of individuals, or they may be merely decorative.  Other terms for gate include yett and port.  The word derives from the old Norse "gata", meaning road or path, and originally referred to the gap in the wall or fence, rather than the barrier which closed it.  The moving part or parts of a gateway may be called "doors", but used for the whole point of entry door usually refers to the entry to a building, or an internal opening between different rooms.

Commutator (electric): A commutator is a moving part of a rotary electrical switch in certain types of electric motors and electrical generators that periodically reverses the current direction between the rotor and the external circuit.  It consists of a cylinder composed of multiple metal contact segments on the rotating armature of the machine.  Two or more electrical contacts called "brushes" made of a soft conductive material like carbon press against the commutator, making sliding contact with successive segments of the commutator as it rotates.  The windings (coils of wire) on the armature are connected to the commutator segments.

Nutating disc engine: A nutating disc engine (also sometimes called a disc engine) is an internal combustion engine comprising fundamentally of one moving part and a direct drive onto the crankshaft.  Initially patented in 1993, it differs from earlier internal combustion engines in a number of ways and utilizes a circular rocking or wobbling "nutating motion", drawing heavily from similar steam-powered engines developed in the 19th century, and similar to the motion of the non-rotating portion of a swash plate on a swash plate engine.

Valve: A valve is a device that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways.  Valves are technically fittings, but are usually discussed as a separate category.  In an open valve, fluid flows in a direction from higher pressure to lower pressure.  The word is derived from the Latin "valva", the moving part of a door, in turn from "volvere", to turn, roll.

Fairsky: The Turbine Steamship Fairsky was a one-class Italian-styled passenger ship operated by the Sitmar Line, best known for service on the migrant passenger route from Britain to Australia from May 1958 until February 1972.  After a 20-month lay-up at Southampton, "Fairsky" completed two further voyages to Australia, before returning to be based at Sydney as a popular full-time cruise ship, until striking an unmarked wreck in 1977 which rendered the vessel uneconomic to permanently repair.  The ship was finally sold to a Philippines based consortium, intended for static use as a casino and floating hotel.  In 1979 during refurbishment at Manila Bay for her new role, a fire broke out onboard which destroyed the accommodation.  The wreck was towed to Hong Kong for demolition in 1980.
