Moelwyn Slate Quarry
Moelwyn quarry is a defunct slate quarry located to the south of the village of Tanygrisiau, north Wales. Some initial prospecting was carried out in the 1820s and again in the 1840s, but it was 1860 before a company was formed, and chambers were excavated. The quarry was never a financial success, and operated sporadically until its demise in 1897. Despite the poor results, a spectacular series of seven inclines were constructed, to enable slates to reach the Ffestiniog Railway. The quarry was hampered by lack of a good water supply, and the mill was constructed between inclines 4 and 5, where water could be obtained from Llyn Stwlan. As in many quarries, barracks were provided, but these were occupied by whole families, living on the mountain, rather than used as lodgings for the quarrymen during the working week. Even in its remote location, there was still a concern for education, with basic literacy classes being run in the 1860s. History Between 1826 and 1828 the Rothsch ...

Gwynedd
Gwynedd (; ) is a county and preserved county (latter with differing boundaries; includes the Isle of Anglesey) in the north-west of Wales. It shares borders with Powys, Conwy County Borough, Denbighshire, Anglesey over the Menai Strait, and Ceredigion over the River Dyfi. The scenic Llŷn Peninsula and most of Snowdonia National Park are in Gwynedd. Bangor is the home of Bangor University. As a local government area, it is the second largest in Wales in terms of land area and also one of the most sparsely populated. A majority of the population is Welsh-speaking. ''Gwynedd'' also refers to being one of the preserved counties of Wales, covering the two local government areas of Gwynedd and Anglesey. Named after the old Kingdom of Gwynedd, both culturally and historically, ''Gwynedd'' can also be used for most of North Wales, such as the area that was policed by the Gwynedd Constabulary. The current area is , with a population of 121,874 as measured in the 2011 Census. Et ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ratgoed Quarry
Ratgoed quarry (also known as Alltgoed quarry) was the northernmost of the slate quarries served by the Corris Railway. It is one mile north of Aberllefenni in Gwynedd, Mid Wales, on the western side of Mynydd Llwydiarth. The quarry primarily worked the Narrow Vein, though it also produced some Broad Vein slates. Original workings The original workings at Alltgoed Quarry date back to before 1844 when a quarter share of the quarry was put up for sale after the bankruptcy of William Hughes. In the second half of 1840s the quarry was closed. It re-opened in 1851. The quarry expanded in the 1850s and was being run by John Rowlands under the auspices of the Alltgoed Consols, a partnership that also owned the nearby Gaewern and Braich Goch quarries. During the early 1860s shareholder discontent lead to the dismissal of Rowlands, with the quarry now being run by the original owner Horatio Nelson Hughes. Rowlands continued to live at Ratgoed Hall after his dismissal, and was also the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slate Mines In Gwynedd
Slate is a fine-grained, foliation (geology), foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcano, volcanic ash (volcanic), ash through low-grade regional metamorphism. It is the finest grained foliated metamorphic rock. Foliation may not correspond to the original sedimentary layering, but instead is in planes perpendicular to the direction of metamorphic compression. The foliation in slate is called "slaty cleavage". It is caused by strong compression causing fine grained clay flakes to regrow in planes perpendicular to the compression. When expertly "cut" by striking parallel to the foliation, with a specialized tool in the quarry, many slates will display a property called fissility (geology), fissility, forming smooth flat sheets of stone which have long been used for roofing, floor tiles, and other purposes. Slate is frequently grey in color, especially when seen, en masse, covering roofs. However, slate o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Croesor Tramway
The Croesor Tramway was a Welsh, narrow gauge railway line built to carry slate from the Croesor slate mines to Porthmadog. It was built in 1864 without an Act of Parliament and was operated using horse power. The tramway was absorbed into the Croesor and Port Madoc Railway in 1865 and later became the Portmadoc, Croesor and Beddgelert Tram Railway in 1879. Part of its route, from Croesor Junction to Porthmadog, was taken over by the Welsh Highland Railway in 1922, and upgraded to allow the operation of steam locomotives. The remainder of the line continued as a horse-drawn tramway, and operated as such until the mid-1940s. History Slate quarrying in the remote Cwm Croesor (Croesor valley) dates back to at least 1846 when the Croesor Quarry opened. Quarrying expanded in the early 1860s and transportation to the shipping wharfs at Porthmadog became a limiting factor. In 1862 discussion began to construct a tramway to connect the valley with the sea. An initial company, the Cr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pumped-storage Hydroelectricity
Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost surplus off-peak electric power is typically used to run the pumps. During periods of high electrical demand, the stored water is released through turbines to produce electric power. Although the losses of the pumping process make the plant a net consumer of energy overall, the system increases revenue by selling more electricity during periods of peak demand, when electricity prices are highest. If the upper lake collects significant rainfall or is fed by a river then the plant may be a net energy producer in the manner of a traditional hydroelectric plant. Pumped-storage hydroelectricity allows energy from intermittent sources (such as solar, wind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ffestiniog Power Station
The Ffestiniog Power Station () is a 360 megawatts pumped-storage hydroelectricity scheme near Ffestiniog, in Gwynedd, north-west Wales. The power station at the lower reservoir has four water turbines, which can generate 360 MW of electricity within 60 seconds of the need arising. The scheme has a storage capacity of around at maximum output for four hours, and the capacity to power the whole of North Wales for several hours. The station, commissioned in 1963, was the first major pumped storage system in the UK. The upper reservoir is Llyn Stwlan with a capacity of approximately which discharges of water to the turbine generators at the power station on the bank of Llyn Ystradau (Tanygrisiau reservoir). The building of the lower reservoir flooded the route of the Ffestiniog Railway which had to build a deviation around the reservoir and power station. The plant is operated by First Hydro, a UK company owned by a joint venture of International Power and Mitsui & Co., and has ...

Bill (proposed Law)
A bill is proposed legislation under consideration by a legislature. A bill does not become law until it is passed by the legislature as well as, in most cases, approved by the executive. Once a bill has been enacted into law, it is called an '' act of the legislature'', or a ''statute''. Bills are introduced in the legislature and are discussed, debated and voted upon. Usage The word ''bill'' is primarily used in Anglophone United Kingdom and United States, the parts of a bill are known as ''clauses'', until it has become an act of parliament, from which time the parts of the law are known as ''sections''. In Napoleonic law nations (including France, Belgium, Luxembourg, Spain and Portugal), a proposed law may be known as a "law project" (Fr. ''projet de loi''), which is a government-introduced bill, or a "law proposition" (Fr. ''proposition de loi''), a private member's bill. For example the Dutch parliamentary system does not make this terminological distinction (''wetsontwe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
House Of Commons Of The United Kingdom
The House of Commons is the lower house of the Parliament of the United Kingdom. Like the upper house, the House of Lords, it meets in the Palace of Westminster in London, England. The House of Commons is an elected body consisting of 650 members known as members of Parliament (MPs). MPs are elected to represent constituencies by the first-past-the-post system and hold their seats until Parliament is dissolved. The House of Commons of England started to evolve in the 13th and 14th centuries. In 1707 it became the House of Commons of Great Britain after the political union with Scotland, and from 1800 it also became the House of Commons for Ireland after the political union of Great Britain and Ireland. In 1922, the body became the House of Commons of the United Kingdom of Great Britain and Northern Ireland after the independence of the Irish Free State. Under the Parliament Acts 1911 and 1949, the Lords' power to reject legislation was reduced to a delaying power. The g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
