Mangorei Power Station
The Mangorei Power Station is a hydroelectric power facility near Mangorei in Taranaki in New Zealand which makes use of water from the Waiwhakaiho River (which is often written as Waiwakaiho) and the Mangamahoe Stream catchments. History Initial 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, utilizing the seasonally consistent water supply provided by Mount Taranaki’s many streams. This 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. In the late 19th century the New Plymouth Borough Council decided to investigate its options for constructing a hydro-electric power station to supply the town with electricity as well as providing a water supply. The nearby Waiwhakaiho River was identified as a suitable source of water. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Plumb Bob
A plumb bob, plumb bob level, or plummet, is a weight, usually with a pointed tip on the bottom, suspended from a string and used as a vertical reference line, or plumb-line. It is a precursor to the spirit level and used to establish a vertical datum. It is typically made of stone, wood, or lead, but can also be made of other metals. If it is used for decoration, it may be made of bone or ivory. The instrument has been used since at least the time of ancient EgyptDenys A. Stocks. Experiments in Egyptian archaeology: stoneworking technology in ncient Egypt'. Routledge; 2003. . p. 180. to ensure that constructions are "plumb", or vertical. It is also used in surveying, to establish the nadir with respect to gravity of a point in space. It is used with a variety of instruments (including levels, theodolites, and steel tapes) to set the instrument exactly over a fixed survey marker or to transcribe positions onto the ground for placing a marker.

Hydroelectric Power Stations 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 ...

Theodolite
A theodolite () is a precision optical instrument for measuring angles between designated visible points in the horizontal and vertical planes. The traditional use has been for land surveying, but it is also used extensively for building and infrastructure construction, and some specialized applications such as meteorology and rocket launching. It consists of a moveable telescope mounted so it can rotate around horizontal and vertical axes and provide angular readouts. These indicate the orientation of the telescope, and are used to relate the first point sighted through the telescope to subsequent sightings of other points from the same theodolite position. These angles can be measured with accuracies down to microradians or seconds of arc. From these readings a plan can be drawn, or objects can be positioned in accordance with an existing plan. The modern theodolite has evolved into what is known as a total station where angles and distances are measured electronically, and ...

Mount Taranaki
Mount Taranaki (), also known as Mount Egmont, is a dormant stratovolcano in the Taranaki region on the west coast of New Zealand's North Island. It is the second highest point in the North Island, after Mount Ruapehu. The mountain has a secondary cone, Fanthams Peak ( mi, Panitahi), , on its south side. Name The name ''Taranaki'' comes from the Māori language. The Māori word means mountain peak, and is thought to come from , meaning "shining", a reference to the snow-clad winter nature of the upper slopes. It was also named and by iwi who lived in the region in "ancient times". Captain Cook named it Mount Egmont on 11 January 1770 after John Perceval, 2nd Earl of Egmont, a former First Lord of the Admiralty who had supported the concept of an oceanic search for ''Terra Australis Incognita''. Cook described it as "of a prodigious height and its top cover'd with everlasting snow," surrounded by a "flat country ... which afforded a very good aspect, being clothed with wood ...

Business The New Zealand electricity reforms of the 1980s split the electricity industry broadly into four sections - generators, transmitters, distributors and retailers. Six main generator businesses (Cont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waiwhakaiho River
The Waiwhakaiho River is a river of the Taranaki Region of New Zealand's North Island. One of many rivers and streams radiating from the slopes of Taranaki/Mount Egmont, it flows initially northeast before veering northwest to reach the Tasman Sea close to the New Plymouth suburb of Fitzroy. Near the sea, it is crossed by the coastal walkway, connecting New Plymouth with Bell Block via the Te Rewa Rewa Bridge. The river is also bridged by SH3 and the Marton–New Plymouth railway line.

New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...
