Iceland
Iceland ( is, Ísland; ) is a Nordic island country in the North Atlantic Ocean and in the Arctic Ocean. Iceland is the most sparsely populated country in Europe. Iceland's capital and largest city is Reykjavík, which (along with its surrounding areas) is home to over 65% of the population. Iceland is the biggest part of the Mid-Atlantic Ridge that rises above sea level, and its central volcanic plateau is erupting almost constantly. The interior consists of a plateau characterised by sand and lava fields, mountains, and glaciers, and many glacial rivers flow to the sea through the lowlands. Iceland is warmed by the Gulf Stream and has a temperate climate, despite a high latitude just outside the Arctic Circle. Its high latitude and marine influence keep summers chilly, and most of its islands have a polar climate. According to the ancient manuscript , the settlement of Iceland began in 874 AD when the Norwegian chieftain Ingólfr Arnarson became the first p ...

Highlands Of Iceland
The Highlands of Iceland ( is, hálendið ) are a sparsely inhabited plateau that covers most of the interior of Iceland. They are situated above 400–500 metres (1300–1600 feet) and are mostly an uninhabitable volcanic desert, because the water precipitating as rain or snow infiltrates so quickly into the ground that it is unavailable for plant growth. This results largely in a surface of grey, black or brown earth, lava and volcanic ashes. A few oasis-like areas, such as Herðubreiðarlindir near Askja, are found only in proximity to rivers. Icelanders categorise the Highlands as: * "Háls", meaning a broad mountain ridge between valleys, such as the one near Langavatn north of Borgarnes; or * "Heiði", meaning the real highlands, such as those alongside the Sprengisandur road. Most of the numerous glaciers, such as Vatnajökull, Langjökull and Hofsjökull, are also part of the Icelandic Highlands. Vegetation is only found on the shores of the glacier rivers. There is al ...

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] |
Landsvirkjun
Landsvirkjun, () the National Power Company of Iceland, is Iceland's largest electricity generator. Landsvirkjun operates 18 power plants in Iceland concentrated on five main areas of operation. History Landsvirkjun was founded on 1 July 1965 by the state of Iceland and the city of Reykjavík. The city of Reykjavík contributed to the company three power stations on the Sog River. Shortly after its founding construction on the Búrfell hydropower station began. From 1965 until 2005 the purpose of Landsvirkjun was to produce and distribute high voltage electricity. The municipality of Akureyri acquired a 5% share in Landsvirkjun in 1983 and became the third owner. Three hydropower stations on the Laxá River previously owned by the municipality of Akureyri were merged into Landsvirkjun. The hydropower stations Búrfell, Sigalda, Hrauneyjafoss, Blanda, Sultartangi, Vatnsfell, and Fljótsdalsstöð were all built by Landsvirkjun. The geothermal power station Krafla came under Lan ...

Watt
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one newton, the rate at which work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit). : ...

Icelandic Hydroelectric Power Stations
Iceland is a world leader in renewable energy. 100% of Iceland's electricity grid is produced from renewable resources. In terms of total energy supply, 85% of the total primary energy supply in Iceland is derived from domestically produced renewable energy sources. Geothermal energy provided about 65% of primary energy in 2016, the share of hydropower was 20%, and the share of fossil fuels (mainly oil products for the transport sector) was 15%. The Icelandic government aspires that the nation will be carbon neutral by 2040. The largest obstacles to this are road transport and the fishing industry. In 2015, the total electricity consumption in Iceland was 18,798 GWh. Renewable energy provided almost 100% of production, with 75% coming from hydropower and 24% from geothermal power. Only two islands, Grimsey and Flatey, are not connected to the national grid and so rely primarily on diesel generators for electricity. Most of the hydropower plants are owned by Landsvirkjun (the Nati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Þórisvatn
Þórisvatn (; sometimes anglicized to Thorisvatn) is the largest lake of Iceland, situated at the south end of Sprengisandur highland road within the highlands of Iceland. It is a reservoir of a surface about 88 km2 and uses the energy of the river Þjórsá, which comes down from the glacier Hofsjökull. Here in the south, it is exploited in a power station. It is like other Icelandic lakes, which are mostly glacial lakes or volcanic lakes, it normally has a stark green color.

Sprengisandur
Sprengisandur () is a highland plateau in Iceland, defined roughly as the area between the Hofsjökull and Vatnajökull glaciers. History and etymology Like Kjölur and Kaldidalur, Sprengisandur is an ancient pass - during the time of the Icelandic Free State (ca. 930–1265) it was one of the several important north–south routes that connected remote regions of the island to the Plains of the Parliament, Þingvellir, where the yearly parliament, Alþingi, was held each year at midsummer. In the sagas of Icelanders it is often called simply ''Sandr'' "Sand" or ''Sandleið'', "Sand trail". At its southern end, it was joined with another such route, Fjallabaksvegur nyrðri, running west from Landmannalaugar mountain hot springs area. Sprengisandur is only accessible during summer - like other parts of the inner desert, it is impassable in winter because of the snow, and in spring because of floods. While being the shortest way to the Alþingi for some Icelanders, for example ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
