Cobb Power Station
The Cobb Power Station is a hydroelectric facility on the Cobb River (New Zealand), Cobb River, in the Tasman District of New Zealand. The power station is located in Upper Tākaka, northwest of Nelson, New Zealand, Nelson. Annual generation is approximately . The initial stages of the construction of the station began as a privately-funded scheme in 1935, but the investor failed to raise the necessary capital. The national government took over building the station and the first power was produced in 1944, operating as a Run-of-the-river hydroelectricity, run-of-river station. A storage dam was completed in 1954. The resulting hydro lake is the highest in the country and at , the station has New Zealand's highest hydraulic head of any power station. History Early supply of electricity to the Nelson /Tasman region included a small scheme at Motueka that had been approved in 1919, and a coal-fired steam generating plant commissioned in Nelson in 1923.

Tasman District
Tasman District () is a local government district in the northwest of the South Island of New Zealand. It borders the Canterbury Region, West Coast Region, Marlborough Region and Nelson City. It is administered by the Tasman District Council, a unitary authority, which sits at Richmond, with community boards serving outlying communities in Motueka and Golden Bay / Mohua. The city of Nelson has its own unitary authority separate from Tasman District, and together they comprise a single region in some contexts, but not for local government functions or resource management (planning) functions. Name Tasman Bay, the largest indentation in the north coast of the South Island, was named after Dutch seafarer, explorer and merchant Abel Tasman. He was the first European to discover New Zealand on 13 December 1642 while on an expedition for the Dutch East India Company. Tasman Bay passed the name on to the adjoining district, which was formed in 1989 largely from the merger of Wai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asbestos
Asbestos ( ) is a group of naturally occurring, Toxicity, toxic, carcinogenic and fibrous silicate minerals. There are six types, all of which are composed of long and thin fibrous Crystal habit, crystals, each fibre (particulate with length substantially greater than width) being composed of many microscopic "fibrils" that can be released into the atmosphere by Abrasion (mechanical), abrasion and other processes. Inhalation of asbestos fibres can lead to various dangerous lung conditions, including mesothelioma, asbestosis, and lung cancer. As a result of these health effects, asbestos is considered a serious Health hazard, health and safety hazard. Archaeological studies have found evidence of asbestos being used as far back as the Stone Age to strengthen ceramic pots, but large-scale mining began at the end of the 19th century when manufacturers and builders began using asbestos for its desirable physical properties. Asbestos is an excellent Thermal insulation, thermal and In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pelton Wheel
The Pelton wheel or Pelton Turbine is an Impulse (physics), 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 Energy conversion efficiency, 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 ov ...

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 of Scots origin, and was inherited from the earlier technology of mill ponds and watermills, with penstocks diverting pond waters to drive the mills. 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 to suit turbine operation and is cut off 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, allowing waters to go anoxic, and desiccation used to dry fouling out so that it may slough off or become easier to remove through manual processes.

Cobb Reservoir
The Cobb Reservoir is a hydro storage lake fed by the Cobb River in the Tasman District of the South Island of New Zealand. The reservoir feeds the Cobb Power Station and is above sea level but drops significantly with low rainfall. Cobb Reservoir is the highest hydro storage lake in New Zealand, and is entirely surrounded by Kahurangi National Park Kahurangi National Park is a national park in the northwest of the South Island of New Zealand. It is the second largest of the thirteen national parks of New Zealand. It was gazetted in 1996 and covers , ranging from the Buller River near Murc ....

Walter Nash
Sir Walter Nash (12 February 1882 – 4 June 1968) was a New Zealand politician who served as the 27th prime minister of New Zealand in the Second Labour Government from 1957 to 1960. He is noted for his long period of political service, having been associated with the New Zealand Labour Party since its creation. Nash was born in the West Midlands, England, and is the most recent New Zealand prime minister to be born outside the country. He arrived in New Zealand in 1909, soon joined the original Labour Party, and became a member of the party's executive in 1919. Guided to politics by his beliefs in Anglicanism, Christian socialism and pacifism, he gained a reputation for brilliant ability as an organiser and administrator which compensated for a lack of charisma and bouts of indecisiveness. Nash was elected to the House of Representatives in the Hutt by-election of 1929. He served as the member of Parliament (MP) for the Hutt electorate for 13 consecutive terms, over a ...
