Mynydd Llwyn-gwern
Mynydd Llwyn-gwern or Mynydd Llwyngwern is a mountain in southern Snowdonia, Wales. It lies above the Afon Dulas to the west and the Nant Ffrydlan to the east. The summit is noted for a series of low Warren (burrow), pillow mounds. The Llwyngwern quarry, Llwyngwern slate quarry on the west flank of the mountain operated from the 1820s until about 1950. In 1972, the quarry became the site for an experiment in green living. This has now developed into the Centre for Alternative Technology which occupies much of the quarry site. The centre built a wind turbine on the summit of Mynydd Llwyn-gwern. It is one of the Dyfi hills.

Welsh Language
Welsh ( or ) is a Celtic language family, Celtic language of the Brittonic languages, Brittonic subgroup that is native to the Welsh people. Welsh is spoken natively in Wales, by some in England, and in Y Wladfa (the Welsh colony in Chubut Province, Argentina). Historically, it has also been known in English as "British", "Cambrian", "Cambric" and "Cymric". The Welsh Language (Wales) Measure 2011 gave the Welsh language official status in Wales. Both the Welsh and English languages are ''de jure'' official languages of the Welsh Parliament, the Senedd. According to the 2021 United Kingdom census, 2021 census, the Welsh-speaking population of Wales aged three or older was 17.8% (538,300 people) and nearly three quarters of the population in Wales said they had no Welsh language skills. Other estimates suggest that 29.7% (899,500) of people aged three or older in Wales could speak Welsh in June 2022. Almost half of all Welsh speakers consider themselves fluent Welsh speakers ...

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] |
Cadair Idris
Cadair Idris or Cader Idris is a mountain in the Meirionnydd area of Gwynedd, Wales. It lies at the southern end of the Snowdonia National Park near the town of Dolgellau. The peak, which is one of the most popular in Wales for walkers and hikers, is composed largely of Ordovician igneous rocks, with classic glacial erosion features such as cwms, moraines, striated rocks, and roches moutonnées. Etymology ''Cadair Idris'' means 'Idris's Chair'. Idris is usually taken to be the name of a giant or, alternatively, it may refer to Idris ap Gwyddno (or Gweiddno), a 7th-century prince of Meirionnydd who won a battle against the Irish on the mountain. Idris ap Gwyddno was in fact referred to as ''Idris Gawr'' ("Idris the Giant") in some mediaeval genealogies of Meirionydd. The basic meaning of the word ''cadair'' (Middle Welsh/Early Modern Welsh ''kadeir'' or ''cadeir'') is 'seat, chair' (borrowed from the Greek ''cathedra'' 'chair'). In place names ''cadair'' can mean 'stronghold, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountain
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited Summit (topography), summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are Monadnock, isolated summits, but most occur in mountain ranges. Mountain formation, Mountains are formed through Tectonic plate, tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through Slump (geology), slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosys ...

Snowdonia
Snowdonia or Eryri (), is a mountainous region in northwestern Wales and a national park of in area. It was the first to be designated of the three national parks in Wales, in 1951. Name and extent It was a commonly held belief that the name is derived from ("eagle"), and thus means "the abode/land of eagles", but recent evidence is that it means ''highlands'', and is related to the Latin (to rise) as leading Welsh scholar Sir proved. The term first appeared in a manuscript in the 9th-century , in an account of the downfall of the semi-legendary 5th-century king (Vortigern). In the Middle Ages, the title ''Prince of Wales and Lord of Snowdonia'' () was used by ; his grandfather used the title ''Prince of north Wales and Lord of Snowdonia.'' The name ''Snowdonia'' derives from '' Snowdon'', the highest mountain in the area and the highest mountain in Wales at . Before the boundaries of the national park were designated, "Snowdonia" was generally used to refer to a sm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Afon Dulas
The Afon Dulas, or North Dulas, is a river forming the border between Merionethshire/Gwynedd and Montgomeryshire/Powys in Wales. Another river called Afon Dulas joins the Dyfi from the south, upstream of its confluence with the North Dulas: locally this is referred to as the South Dulas. Route of North Dulas Afon Dulas rises from a source in the hills above Aberllefenni and passes through Corris, Esgairgeiliog and Pantperthog before joining the Afon Dyfi at Ffridd Gate near Machynlleth. History The Dulas is recorded as an important land boundary in 1200, in a document written in 1428. This document describes the land owned by Einion ap Seisyllt, in the time of Llywelyn the Great, as "tota terra inter aquas de Dyfi et Delwas" (Latin, meaning: all the land between the rivers Dyfi and Dulas). Roads and railways in the Dulas valley * The A487 trunk road follows the valley from Ffridd Gate to Corris * The Roman road Sarn Helen probably followed the valley from Aberllefenni to ...

Warren (burrow)
A warren is a network of wild rodent or lagomorph, typically rabbit burrows. Domestic warrens are artificial, enclosed establishment of animal husbandry dedicated to the raising of rabbits for meat and fur. The term evolved from the medieval Anglo-Norman concept of free warren, which had been, essentially, the equivalent of a hunting license for a given woodland. Architecture of the domestic warren The cunicularia of the monasteries may have more closely resembled hutches or pens, than the open enclosures with specialized structures which the domestic warren eventually became. Such an enclosure or ''close'' was called a ''cony-garth'', or sometimes ''conegar'', ''coneygree'' or "bury" (from "burrow"). Moat and pale To keep the rabbits from escaping, domestic warrens were usually provided with a fairly substantive moat, or ditch filled with water. Rabbits generally do not swim and avoid water. A ''pale'', or fence, was provided to exclude predators. Pillow mounds The most char ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Llwyngwern Quarry
The Llwyngwern quarry (sometimes known as Glandulas quarry or Maglona quarry) was a slate quarry in Wales that opened by 1828 and continued working until about 1950. The quarry is located on the western flank of Mynydd Llwyn-gwern. History Llwyngwern was a small quarry that only briefly produced more than 2000 tons of finished slate per year. It worked a minor outcropping of slate away from the main veins quarried to the north around Corris and Aberllefenni. Early history The quarry began working no later than 1828, when Joseph Tyler was appointed the quarry manager; he was the son of the manager of Diffwys quarry in Blaenau Ffestiniog. In 1835, the quarry was owned by Simon Cook of Llwyngwern, though it closed in the 1840s. In 1853 it was re-opened by W.R. Williams of Dolgellau and was described as a well-developed quarry with a waterwheel powering the mill. In 1863, a new company, the Llwyngwern Slate Quarry Co. Ltd, was formed to work the quarry, under the ownership o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centre For Alternative Technology
The Centre for Alternative Technology (CAT) ( cy, Canolfan y Dechnoleg Amgen) is an eco-centre in Powys, mid-Wales, dedicated to demonstrating and teaching sustainable development. CAT, despite its name, no longer concentrates its efforts exclusively on alternative technology, but provides information on all aspects of sustainable living. It is open to visitors, offers postgraduate degrees as well as shorter residential and one day courses; and publishes information on renewable energy, sustainable architecture, organic farming, gardening, and sustainable living. CAT also runs education programmes for schools and sells environmentally friendly items through its on site shop, restaurant and mail order department. History CAT was founded by businessman-turned-environmentalist Gerard Morgan-Grenville, and opened in 1973 in the disused Llwyngwern slate quarry near Machynlleth (once served by the narrow-gauge Corris Railway), where it occupies a seven-acre (28,000 m2) site.

Wind Turbine
A wind turbine is a device that converts the kinetic energy of wind into electrical energy. Hundreds of thousands of large turbines, in installations known as wind farms, now generate over 650 gigawatts of power, with 60 GW added each year. Wind turbines are an increasingly important source of intermittent renewable energy, and are used in many countries to lower energy costs and reduce reliance on fossil fuels. One study claimed that, wind had the "lowest relative greenhouse gas emissions, the least water consumption demands and the most favorable social impacts" compared to photovoltaic, hydro, geothermal, coal and gas energy sources. Smaller wind turbines are used for applications such as battery charging for auxiliary power for boats or caravans, and to power traffic warning signs. Larger turbines can contribute to a domestic power supply while selling unused power back to the utility supplier via the electrical grid. Wind turbines are manufactured in a wide range of ...
