Little River (New Zealand)
The Little River is a tributary of Rakaia River, about long, in the Canterbury Plains of New Zealand's South Island. It rises on the Mount Hutt and enters the Rakaia above sea level. Little River is also the name of a short river, roughly , on Stewart Island, about a 2-hour walk from Oban. Wairewa marae, a ''marae'' (tribal meeting ground) of Ngāi Tahu and its Wairewa Rūnanga branch, is located at Little River. It includes Te Mako ''wharenui'' (meeting house). Power station MainPower’s Cleardale power station, was built in 2010. It takes up to /second through a fibreglass penstock, up from, and above, the station, to drive a pelton wheel.

Mount Hutt
Mount Hutt ( mi, Opuke) rises to the west of the Canterbury Plains in the South Island of New Zealand, above the braided upper reaches of the Rakaia River, and 80 kilometres west of Christchurch. Its summit is 2190 metres above sea level. The New Zealand Ministry for Culture and Heritage gives a translation of "place of the hill" for ''Ōpuke''. Ski field The mountain is home to a commercial alpine ski area offering 3.65 square kilometres of skiable terrain and a vertical of 683 metres.

Wharenui
A wharenui (; literally "large house") is a communal house of the Māori people of New Zealand, generally situated as the focal point of a ''marae''. Wharenui are usually called meeting houses in New Zealand English, or simply called ''whare'' (a more generic term simply referring to a house or building). Also called a ''whare rūnanga'' ("meeting house") or ''whare whakairo'' (literally "carved house"), the present style of wharenui originated in the early to middle nineteenth century. The houses are often carved inside and out with stylized images of the iwi's (or tribe's) ancestors, with the style used for the carvings varying from tribe to tribe. Modern meeting houses are built to regular building standards. Photographs of recent ancestors may be used as well as carvings. The houses always have names, sometimes the name of a famous ancestor or sometimes a figure from Māori mythology. Some meeting houses are built at places that are not the location of a tribe, but where many ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Wheel
A water wheel is a machine for converting the energy of flowing or falling water into useful forms of power, often in a watermill. A water wheel consists of a wheel (usually constructed from wood or metal), with a number of blades or buckets arranged on the outside rim forming the driving car. Water wheels were still in commercial use well into the 20th century but they are no longer in common use. Uses included milling flour in gristmills, grinding wood into pulp for papermaking, hammering wrought iron, machining, ore crushing and pounding fibre for use in the manufacture of cloth. Some water wheels are fed by water from a mill pond, which is formed when a flowing stream is dammed. A channel for the water flowing to or from a water wheel is called a mill race. The race bringing water from the mill pond to the water wheel is a headrace; the one carrying water after it has left the wheel is commonly referred to as a tailrace. Waterwheels were used for various purposes from ag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electricity Ashburton
Electricity Ashburton Limited, trading as EA Networks is a co-operatively-owned electricity distribution company, based in Ashburton, New Zealand.

Pelton Wheel
The Pelton wheel or Pelton Turbine is an impulse-type water turbine invented by American inventor Lester Allan Pelton in the 1870s. The Pelton wheel extracts energy from the impulse of moving water, as opposed to water's dead weight like the traditional overshot water wheel. Many earlier variations of impulse turbines existed, but they were less efficient than Pelton's design. Water leaving those wheels typically still had high speed, carrying away much of the dynamic energy brought to the wheels. Pelton's paddle geometry was designed so that when the rim ran at half the speed of the water jet, the water left the wheel with very little speed; thus his design extracted almost all of the water's impulse energywhich made for a very efficient turbine. History file:Pelton wheel (patent).png, Figure from Lester Allan Pelton's original October 1880 patent Lester Allan Pelton was born in Vermillion, Ohio in 1829. In 1850, he traveled overland to take part in the California Gold Rush. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Penstock
A penstock is a sluice or gate or intake structure that controls water flow, or an enclosed pipe that delivers water to hydro turbines and sewerage systems. The term is inherited from the earlier technology of mill ponds and watermills. Hydroelectric systems and dams Penstocks for hydroelectric installations are normally equipped with a gate system and a surge tank. They can be a combination of many components such as anchor block, drain valve, air bleed valve, and support piers depending on the application. Flow is regulated by turbine operation and is nil when turbines are not in service. Penstocks, particularly where used in polluted water systems, need to be maintained by hot water washing, manual cleaning, antifouling coatings, and desiccation. The term is also used in irrigation dams to refer to the channels leading to and from high-pressure sluice gates. Penstocks are also used in mine tailings dam construction. The penstock is usually situated fairly close to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fiberglass
Fiberglass (American English) or fibreglass (Commonwealth English) is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinyl ester resin—or a thermoplastic. Cheaper and more flexible than carbon fiber, it is stronger than many metals by weight, non- magnetic, non-conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under many circumstances. Applications include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, orthopedic casts, surfboards, and external door skins. Other common names for fiberglass are glass-reinforced plastic (GRP), glass-fiber reinforced plastic (GFRP) or GF ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rakaia River
The Rakaia River is in the Canterbury Plains in New Zealand's South Island. The Rakaia River is one of the largest braided rivers in New Zealand. The Rakaia River has a mean flow of and a mean annual seven-day low flow of . In the 1850s, European settlers named it the ''Cholmondeley River'', but this name lapsed into disuse. Description It rises in the Southern Alps, travelling in a generally easterly or southeasterly direction before entering the Pacific Ocean south of Christchurch. It forms a hapua as it reaches the ocean. For much of its journey, the river is braided river, braided, running through a wide shingle bed. Close to Mount Hutt, however, it is briefly confined to a narrow canyon known as the Rakaia Gorge. The Rakaia River is bridged in two places. The busiest crossing is at the small town of Rakaia, from the river mouth, where State Highway 1 (New Zealand), State Highway 1 using Rakaia Bridge and the South Island Main Trunk Railway cross the river using sepa ...

Ngāi Tahu
Ngāi Tahu, or Kāi Tahu, is the principal Māori (tribe) of the South Island. Its (tribal area) is the largest in New Zealand, and extends from the White Bluffs / Te Parinui o Whiti (southeast of Blenheim), Mount Mahanga and Kahurangi Point in the north to Stewart Island / Rakiura in the south. The comprises 18 (governance areas) corresponding to traditional settlements. Ngāi Tahu originated in the Gisborne District of the North Island, along with Ngāti Porou and Ngāti Kahungunu, who all intermarried amongst the local Ngāti Ira. Over time, all but Ngāti Porou would migrate away from the district. Several were already occupying the South Island prior to Ngāi Tahu's arrival, with Kāti Māmoe only having arrived about a century earlier from the Hastings District, and already having conquered Waitaha, who themselves were a collection of ancient groups. Other that Ngāi Tahu encountered while migrating through the South Island were Ngāi Tara, Rangitāne, Ngāti T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marae
A ' (in New Zealand Māori, Cook Islands Māori, Tahitian), ' (in Tongan), ' (in Marquesan) or ' (in Samoan) is a communal or sacred place that serves religious and social purposes in Polynesian societies. In all these languages, the term also means cleared and free of weeds or trees. generally consist of an area of cleared land roughly rectangular (the itself), bordered with stones or wooden posts (called ' in Tahitian and Cook Islands Māori) perhaps with ' (terraces) which were traditionally used for ceremonial purposes; and in some cases, a central stone ' or ''a'u''. In the Rapa Nui culture of Easter Island, the term ' has become a synonym for the whole marae complex. In some modern Polynesian societies, notably that of the Māori of New Zealand, the marae is still a vital part of everyday life. In tropical Polynesia, most marae were destroyed or abandoned with the arrival of Christianity in the 19th century, and some have become an attraction for tourists or archaeol ...
