Cwm Dyli
Cwm Dyli is the location of a hydro-electric power station on the southern flank of the Snowdon range in North Wales. At the time it was built, it was the largest hydro-electric power station in the United Kingdom. It is Britain's oldest power station, and is believed to be one of the oldest Grid-connected hydro-electric stations in the world. History The station was built in 1905 by the Porthmadog, Beddgelert and South Snowdon Railway company, backed by North Wales Power and Traction Co Ltd to supply electricity to its own electric railway and connected slate quarries and mines. The railway was planned to run through the same valley as the power station and be fed with an electrical feeder, but the enterprise ran short of funds and the attempt was abandoned. The company was renamed the North Wales Power Company Limited. In August 1906, power from Cwm Dyli was used to power the Oakeley Quarry in Blaenau Ffestiniog carried over the Crimea Pass by a long overhead transmiss ...

Hydro-electric
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.

Beddgelert
Beddgelert () is a village and community in the Snowdonia area of Gwynedd, Wales. The population of the community taken at the 2011 census was 455, and includes Nantmor and Nant Gwynant. It is reputed to be named after the legendary hound Gelert. The community is large and sparsely populated and covers 86 square kilometres. Location The village stands in a valley at the confluence of the River Glaslyn and the River Colwyn. Just above the confluence of the rivers, in the centre of the village, is an old stone bridge with two arches. The River Gwynant also exists in the area, coinciding with the River Colwyn under what locals know as ‘Pont Bren’, creating the River Glaslyn. Many of the houses and hotels are built of local dark stone. To the west is Moel Hebog and its neighbours to the north and a series of hills rising to the top of Snowdon. A lane of the A4085 between Caernarfon (13 miles north) and Porthmadog (8 miles south) runs through the village. The outdoor e ...

Buildings And Structures In Gwynedd
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 artis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dolgarrog Power Station
Dolgarrog power station in Dolgarrog, Wales was originally built in 1907 as part of an aluminium smelting plant. It uses water turbines to drive electricity alternators. Public supplies began in 1922 when power lines were constructed to transmit electricity from the power station to Colwyn Bay, Conwy and Llandudno. The station was vested in the British Electricity Authority and its successors following nationalisation in 1948. It is currently (2021) operated by RWE NPower UK. History Dolgarrog hydro-electric power station was commissioned in 1907 by the Aluminium Corporation of Dolgarrog to supply electricity to its aluminium smelting plant. The smelting of the mineral bauxite to make aluminium is an energy intensive process requiring a large amount of electricity. The availability of cheap hydro-electric power was therefore attractive. The construction of the power station was sanctioned under the provisions of the ''North Wales Electric Power Act 1904''. Water was drawn from Lly ...

Hydroelectricity In The United Kingdom
, hydroelectric power stations in the United Kingdom accounted for 1.87GW of installed electrical generating capacity, being 2.2% of the UK's total generating capacity and 4.2% of UK's renewable energy generating capacity. This includes four conventional hydroelectric power stations and run-of-river schemes for which annual electricity production is approximately 5,000 GWh, being about 1.3% of the UK's total electricity production. There are also pumped-storage hydroelectric power stations providing a further 2.8GW of installed electrical generating capacity, and contributing up to 4,075GWh of peak demand electricity annually. The potential for further practical and viable hydroelectricity power stations in the UK is estimated to be in the region of 146 to 248MW for England and Wales, and up to 2,593MW for Scotland. Interest in hydropower in the UK rose in the early 2010s due to UK and EU targets for reductions in carbon emissions and the promotion of renewable energy power gen ...

Alternator
An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature.Gordon R. Selmon, ''Magnetoelectric Devices'', John Wiley and Sons, 1966 no ISBN pp. 391-393 Occasionally, a linear alternator or a rotating armature with a stationary magnetic field is used. In principle, any AC electrical generator can be called an alternator, but usually the term refers to small rotating machines driven by automotive and other internal combustion engines. An alternator that uses a permanent magnet for its magnetic field is called a magneto. Alternators in power stations driven by steam turbines are called turbo-alternators. Large 50 or 60 Hz three-phase alternators in power plants generate most of the world's electric power, which is distributed by electric power grids. History Alternating current generating ...

Pelton Wheel
The Pelton wheel or Pelton Turbine is an 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 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 overland to take part in the California Gold Rush. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
