Klabböle Power Plant
Klabböle Power Plant (''Swedish:'' Klabböle Kraftverk) was a hydroelectric plant located near Umeå in northern Sweden. The plant was commissioned in 1899 and supplied power to the city until 1958, when it was replaced by a newly constructed state-owned power plant in Norrforsen. Klabböle Kraftverk is now a museum located at Ume River's south bank, below the village of Klabböle, about upstream from Umeå. History In the 1500s, there was a water mill in Klabböleforsen which was used for grinding flour and for powering a saw. A steam-powered plant was located in the centre of Umeå, but by 1892 it needed to be replaced and the city agreed to use the rapids to build a hydroelectric plant in 1897. The work was subcontracted to the Qvist & Gjers engineering company in Arboga. Qvist & Gjers designed, engineered, and built the plant with two turbine-generator units totaling 400 kW, along with extra space for two more should they be needed in the future. Due to financial const ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Umeå
Umeå ( , , , locally ; South Westrobothnian: ;). fi, Uumaja; sju, Ubmeje; sma, Upmeje; se, Ubmi) is a city in northeast Sweden. It is the seat of Umeå Municipality and the capital of Västerbotten County. Situated on the Ume River, Umeå is the largest locality in Norrland and the thirteenth largest in Sweden, with a wider municipal population of 130,224 inhabitants in 2020. When Umeå University was established in 1965, growth accelerated, and the amount of housing has doubled in 30 years from 1980 to 2010. , Umeå was gaining around 1000 inhabitants per year and the municipality plans for having 200 000 inhabitants by 2050. The projection of municipality size in 2050 has, however, been questioned as an overestimation in an independent study. Umeå is a university town and centre of education, technical and medical research in northern Sweden. The two universities located in the city, Umeå University and one of the 3 main branches of SLU, host around 40,000 enrolled s ...

Slush
Slush, also called slush ice, is a slurry mixture of small ice crystals (e.g., snow) and liquid water. In the natural environment, slush forms when ice or snow melts or during mixed precipitation. This often mixes with dirt and other pollutants on the surface, resulting in a gray or muddy brown color. Often, solid ice or snow can block the drainage of fluid water from slushy areas, so slush often goes through multiple freeze/thaw cycles before being able to completely drain and disappear. In areas where road salt is used to clear roadways, slush forms at lower temperatures in salted areas than it would ordinarily. This can produce a number of different consistencies over the same geographical area with scattered salted areas covered with slush and others covered with frozen precipitation . Hazards Because slush behaves like a non-Newtonian fluid, which means it behaves like a mostly solid mass until its inner shear forces rise beyond a specific threshold and beyond can ver ...

Dams Completed In 1899
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hydroelectric Power Stations In Sweden
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.

Stornorrfors Hydroelectric Power Station
Stornorrfors Hydroelectric Power Station ( sv, Stornorrfors kraftverk, links=no) is a hydroelectric power station on the Ume River in Västerbotten County, Sweden. The city of Umeå lies about 15 km southeast of the power station. Prior to the construction of Stornorrfors, the Klabböle Power Plant supplied power to the city of Umeå several kilometers downstream from Stornorrfors. Klabböle's power plant was commissioned in 1899, and supplied power to the city until 1958, when Stornorrfors began operating. Stornorrfors is owned by Vattenfall (75 %; municipality of Umeå 25 %) and operated by Vattenfall. It generates more electricity per year than any other hydroelectric power plant in Sweden and is the country's second largest in power production. Dam Stornorrfors Dam is a concrete gravity dam located about 4 km from the power station. A canal connects the reservoir with the power station. Power station The power station contains 4 (or 5) Francis turbine-generators. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vattenfall
Vattenfall is a Swedish multinational power company owned by the Swedish State. Beyond Sweden, the company generates power in Denmark, Finland, Germany, the Netherlands, and the United Kingdom. The company's name is Swedish for "waterfall", and is an abbreviation of its original name, Royal Waterfall Board (''Kungliga Vattenfallstyrelsen''). History Vattenfall (then called ''Kungliga Vattenfallsstyrelsen'' or Royal Waterfall Board) was founded in 1909 as a state-owned enterprise in Sweden. From its founding until the mid-1970s, Vattenfall's business was largely restricted to Sweden, with a focus on hydroelectric power generation. Only in 1974 did the company begin to build nuclear reactors in Sweden (the Ringhals 1 and 2 reactors), eventually owning seven of Sweden's 12 reactors. In 1992, Vattenfall was reformed as the limited liability company Vattenfall AB. At the same time, the transmission grid (220 kV and 400 kV lines) was transferred to the newly formed state agency Svens ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Supercooling
Supercooling, also known as undercooling, is the process of lowering the temperature of a liquid or a gas below its melting point without it becoming a solid. It achieves this in the absence of a seed crystal or nucleus around which a crystal structure can form. The supercooling of water can be achieved without any special techniques other than chemical demineralization, down to −48.3 °C (−55 °F). Droplets of supercooled water often exist in stratus and cumulus clouds. An aircraft flying through such a cloud sees an abrupt crystallization of these droplets, which can result in the formation of ice on the aircraft's wings or blockage of its instruments and probes. Animals utilize supercooling to survive in extreme temperatures. There are many mechanisms that aid in maintaining a liquid state, such as the production of antifreeze proteins, which bind to ice crystals to prevent water molecules from binding and spreading the growth of ice. The winter flounder is on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ume River
The Ume River (Swedish: ''Ume älv'' or ''Umeälven'') is one of the main rivers in northern Sweden. It is around long, and flows in a south-eastern direction from its source, the lake ''Överuman'' by the Norway, Norwegian border within the Scandinavian mountain range. For large parts, the European route E12, also known as Blå Vägen (Blue Route), follows its path. It passes through Vindelfjällen Nature Reserve and Storuman (lake), Lake Storuman and drains into the Gulf of Bothnia on Sweden's east coast at the small town of Holmsund, and adjacent to the city of Umeå. Its chief tributary is the Vindel River. In the 1950s, hydroelectricity developments were building reservoirs and dams throughout the country (see also: energy in Sweden), but concerns were being raised against the environmental impact of these power plants. In particular, there were heated discussions about the developments on the Ume River and Vindel River. This led in 1961 an agreement called the Peace of Sarek ...
