Motukawa Power Station
The Motukawa Power Station is a hydroelectric power facility in Taranaki in New Zealand which makes use of water from the Manganui River and Waitara River catchments. Water is drawn from behind a weir on the Manganui River near Tariki and diverts this water through a race to Lake Ratapiko and then through penstocks to the Motukawa Power Station. The power station discharges into the Mākara Stream, a tributary of the Waitara River. History Development Of the first 14 publicly available electricity supplies in New Zealand, seven were in the province of Taranaki. Most of these were hydroelectric schemes, utilising the seasonally consistent water supply provided by Mount Taranaki’s many streams. These development was driven by the demand for electric lighting by both town and rural dwellers plus farmers wishing to power their new electric shearing sheds, milking machines and separator.

Taranaki, New Zealand
Taranaki is a region in the west of New Zealand's North Island. It is named after its main geographical feature, the stratovolcano of Mount Taranaki, also known as Mount Egmont. The main centre is the city of New Plymouth. The New Plymouth District is home to more than 65 per cent of the population of Taranaki. New Plymouth is in North Taranaki along with Inglewood and Waitara. South Taranaki towns include Hāwera, Stratford, Eltham, and Ōpunake. Since 2005, Taranaki has used the promotional brand "Like no other". Geography Taranaki is on the west coast of the North Island, surrounding the volcanic peak of Mount Taranaki. The region covers an area of 7258 km2. Its large bays north-west and south-west of Cape Egmont are North Taranaki Bight and South Taranaki Bight. Mount Taranaki is the second highest mountain in the North Island, and the dominant geographical feature of the region. A Māori legend says that Mount Taranaki previously lived with the Tongariro, Ngaur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Plymouth
New Plymouth ( mi, Ngāmotu) is the major city of the Taranaki region on the west coast of the North Island of New Zealand. It is named after the English city of Plymouth, Devon from where the first English settlers to New Plymouth migrated. The New Plymouth District, which includes New Plymouth City and several smaller towns, is the 10th largest district (out of 67) in New Zealand, and has a population of – about two-thirds of the total population of the Taranaki Region and % of New Zealand's population. This includes New Plymouth City (), Waitara (), Inglewood (), Ōakura (), Ōkato (561) and Urenui (429). The city itself is a service centre for the region's principal economic activities including intensive pastoral activities (mainly dairy farming) as well as oil, natural gas and petrochemical exploration and production. It is also the region's financial centre as the home of the TSB Bank (formerly the Taranaki Savings Bank), the largest of the remaining non-governm ...

Hydroelectricity In New Zealand
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Transpower New Zealand
Transpower New Zealand Limited (TPNZ) is the state-owned enterprise responsible for electric power transmission in New Zealand. It performs two major functions in the New Zealand electricity market. As the owner of the National Grid it provides the infrastructure of electric power transmission that allows consumers to have access to generation from a wide range of sources, and enables competition in the wholesale electricity market; as system operator it manages the real-time operation of the grid and the physical operation of the electricity market. Transpower was initially formed as an operating division of the Electricity Corporation of New Zealand (ECNZ) in 1987. In 1994 it was separated from ECNZ and corporatised to become a state-owned enterprise with its own board of directors and ministerial shareholders, the Minister of Finance and the Minister of State-Owned Enterprises.

New Zealand Longfin Eel
The New Zealand longfin eel (''Anguilla dieffenbachii'') is a species of freshwater eel that is endemic to New Zealand. It is the largest freshwater eel in New Zealand and the only endemic species – the other eels found in New Zealand are the native shortfin eel (''Anguilla australis''), also found in Australia, and the naturally introduced Australian longfin eel (''Anguilla reinhardtii''). Longfin eels are long-lived, migrating to the Pacific Ocean near Tonga to breed at the end of their lives. They are good climbers as juveniles and so are found in streams and lakes a long way inland. An important traditional food source for Māori, longfin eels numbers are declining and they are classified as endangered, but over one hundred tonnes are still commercially fished each year. Description The easiest way to identify the longfin eel is by the length of its fins: the dorsal (top) fin is about two-thirds the length of the body and starts significantly further towards the head than ...

Fish Ladder
A fish ladder, also known as a fishway, fish pass, fish steps, or fish cannon is a structure on or around artificial and natural barriers (such as dams, locks and waterfalls) to facilitate diadromous fishes' natural migration as well as movements of potamodromous species. Most fishways enable fish to pass around the barriers by swimming and leaping up a series of relatively low steps (hence the term ''ladder'') into the waters on the other side. The velocity of water falling over the steps has to be great enough to attract the fish to the ladder, but it cannot be so great that it washes fish back downstream or exhausts them to the point of inability to continue their journey upriver. History Written reports of rough fishways date to 17th-century France, where bundles of branches were used to make steps in steep channels to bypass obstructions. A pool and weir salmon ladder was built around 1830 by James Smith, a Scottish engineer on the River Teith, near Deanston, Perthshire ...

Shotcrete
Shotcrete, gunite (), or sprayed concrete is concrete or mortar conveyed through a hose and pneumatically projected at high velocity onto a surface, as a construction technique, first used in 1907 invented by Carl Akeley. It is typically reinforced by conventional steel rods, steel mesh, or fibers. Shotcrete is usually an all-inclusive term for both the wet-mix and dry-mix versions invented by Akeley. In pool construction, however, ''shotcrete'' refers to wet mix and ''gunite'' to dry mix. In this context, these terms are not interchangeable. Shotcrete is placed and compacted/consolidated at the same time, due to the force with which it is ejected from the nozzle. It can be sprayed onto any type or shape of surface, including vertical or overhead areas. Shotcrete has the characteristics of high compressive strength, good durability, water tightness and frost resistance. History Shotcrete, then known as gunite, was invented in 1907 by American taxidermist Carl Akeley to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mudstone
Mudstone, a type of mudrock, is a fine-grained sedimentary rock whose original constituents were clays or muds. Mudstone is distinguished from '' shale'' by its lack of fissility (parallel layering).Blatt, H., and R.J. Tracy, 1996, ''Petrology.'' New York, New York, W. H. Freeman, 2nd ed, 529 pp. The term ''mudstone'' is also used to describe carbonate rocks (limestone or dolomite) that are composed predominantly of carbonate mud. However, in most contexts, the term refers to siliciclastic mudstone, composed mostly of silicate minerals. The NASA Curiosity rover has found deposits of mudstone on Mars that contain organic substances such as propane, benzene and toluene. Definition There is not a single definition of mudstone that has gained general acceptance,Boggs 2006, p.143 though there is wide agreement that mudstones are fine-grained sedimentary rocks, composed mostly of silicate grains with a grain size less than . Individual grains this size are too small to be disting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waitara, New Zealand
Waitara is a town in the northern part of the Taranaki region of the North Island of New Zealand. Waitara is located just off State Highway 3, northeast of New Plymouth. Waitara was the site of the outbreak of the Taranaki Wars in 1860 following the attempted purchase of land for British settlers from its Māori owners. Disputes over land that was subsequently confiscated by the Government continue to this day. The commonly accepted meaning of the name Waitara is "mountain stream", though Maori legend also states that it was originally Whai-tara—"path of the dart". In 1867 the settlement was named Raleigh, after Sir Walter Raleigh. It reverted to its former name with the establishment of the borough of Waitara in 1904. History and culture Early history Prior to European colonisation, Waitara lay on the main overland route between the Waikato and Taranaki districts. Vestiges of numerous pā on all strategic heights in the district indicate close settlement and closely c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
