Okere Falls Power Station
Okere Falls Power Station is a hydroelectric power station that came into production in May 1901, bringing electricity to Rotorua. At the time, Rotorua was only the fourth town in New Zealand to have electricity. The power station was the first power station built by the New Zealand government, and it remained in operation until 1936. History With Rotorua's expanding tourism industry in the 19th century, demand grew for having electrical lighting. In 1897, land was secured at Okere Falls for a powerhouse, followed by a tender in 1899 to build a hydro-electric power plant.Information contained on "Power for People" information panel at the viewing platform over Okere Falls. Rotorua's demand for electricity grew rapidly and by 1907 could not be met by the existing turbine anymore. In 1908, a new wing dam out from the head gates into the river was completed, bringing in enough water to run a second turbine, doubling the station's output to .

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 ...

Kaituna River
The Kaituna River is in the Bay of Plenty region of the North Island of New Zealand. It is the outflow from Lakes Lake Rotorua, Rotorua and Lake Rotoiti (Bay of Plenty), Rotoiti, and flows northwards for , emptying into the Bay of Plenty near Te Puke. It was the subject of a claim concerning the effluent flowing down the river from Lake Rotorua, which resulted in movement to a land treatment system. The New Zealand Ministry for Culture and Heritage gives a translation of "eat eels" for ''Kaituna''. The upper section of the Kaituna, also referred to as Okere River, offers some of the best whitewater kayaking and rafting in the world, with the Okere Falls area containing the highest commercially rafted waterfall, , in the world. It is also famous for its trout fishing. Cultural claim During the 1970s Lake Rotorua was becoming eutrophication, eutrophic under heavy nutrient loadings, leading the New Zealand Ministry of Works, Ministry of Works to propose diverting some sewage flow ...

Rotorua
Rotorua () is a city in the Bay of Plenty region of New Zealand's North Island. The city lies on the southern shores of Lake Rotorua, from which it takes its name. It is the seat of the Rotorua Lakes District, a territorial authority encompassing Rotorua and several other nearby towns. Rotorua has an estimated resident population of , making it the country's 12th largest urban area, and the Bay of Plenty's second largest urban area behind Tauranga. Rotorua is a major destination for both domestic and international tourists; the tourism industry is by far the largest industry in the district.

This thermal activity is sourced to the Rotorua Caldera, in which the town lies. Rotorua is home to the Toi Ohomai Institute of Technology. History The name Rotorua comes from the Māori language, where the full name for the city and lake is . ''Roto'' m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Okere Falls
Okere Falls is a small town located 21 km from Rotorua on SH 33 between Rotorua and Tauranga on the North Island of New Zealand.

Waterfall
A waterfall is a point in a river or stream where water flows over a vertical drop or a series of steep drops. Waterfalls also occur where meltwater drops over the edge of a tabular iceberg or ice shelf. Waterfalls can be formed in several ways, but the most common method of formation is that a river courses over a top layer of resistant bedrock before falling on to softer rock, which Erosion, erodes faster, leading to an increasingly high fall. Waterfalls have been studied for their impact on species living in and around them. Humans have had a distinct relationship with waterfalls for years, travelling to see them, exploring and naming them. They can present formidable barriers to navigation along rivers. Waterfalls are religious sites in many cultures. Since the 18th century they have received increased attention as tourist destinations, sources of hydropower, andparticularly since the mid-20th centuryas subjects of research.

Dynamo
file:DynamoElectricMachinesEndViewPartlySection USP284110.png, "Dynamo Electric Machine" (end view, partly section, ) A dynamo is an electrical generator that creates direct current using a commutator (electric), commutator. Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later Electric power conversion, electric-power conversion devices were based, including the electric motor, the Alternating current, alternating-current alternator, and the rotary converter. Today, the simpler alternator dominates large scale Electricity generation, power generation, for efficiency, reliability and cost reasons. A dynamo has the disadvantages of a commutator (electric), mechanical commutator. Also, converting alternating to direct current using rectifiers (such as vacuum tubes or more recently via Solid state (electronics), solid state technology) is effective and usually economical.

Buildings And Structures In The Bay Of Plenty Region
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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.
