Tidal Stream Generators
A tidal stream generator, often referred to as a tidal energy converter (TEC), is a machine that extracts energy from moving masses of water, in particular tides, although the term is often used in reference to machines designed to extract energy from run of river or tidal estuarine sites. Certain types of these machines function very much like underwater wind turbines, and are thus often referred to as tidal turbines. They were first conceived in the 1970s during the oil crisis.Jones, Anthony T., and Adam Westwood. "Power from the oceans: wind energy industries are growing, and as we look for alternative power sources, the growth potential is through the roof. Two industry watchers take a look at generating energy from wind and wave action and the potential to alter." The Futurist 39.1 (2005): 37(5). GALE Expanded Academic ASAP. Web. 8 October 2009. Tidal stream generators are the cheapest and the least ecologically damaging among the four main forms of tidal power generation. ...

Evopod In Strangford Lough 2008
Evopod is a unique tidal energy device being developed by a UK-based company Oceanflow Energy Ltd for generating electricity from tidal streams and ocean currents. It can operate in exposed deep water sites where severe wind and waves also make up the environment. Floating tethered turbines Advantages *The flow speed in tidal streams and ocean currents tends to be fastest near the surface and falls off in speed as one descend in the water column. As the power that can be extracted from the free flowing water is proportional to the velocity cubed, then a 10% increase in flow speed equates to a 33% increase in power per unit swept area of the turbine.Black and Veatch (17-7-2005"TIDAL STREAM ENERGY - RESOURCE AND TECHNOLOGY SUMMARY REPORT"(PDF) Retrieved on 11-06-2009. *The flow is generally more consistent in the top 1/3 of the water column as it is well away from disturbances created by the seabed topography. *The drag force on turbines of the same power output is proport ...

Lynmouth
Lynmouth is a village in Devon, England, on the northern edge of Exmoor. The village straddles the confluence of the West Lyn and East Lyn rivers, in a gorge below Lynton, which was the only place to expand to once Lynmouth became as built-up as possible. The villages are connected by the Lynton and Lynmouth Cliff Railway, which works two cable-connected cars by gravity, using water tanks. The two villages are a civil parish governed by Lynton and Lynmouth Town Council. The parish boundaries extend southwards from the coast, and include hamlets such as Barbrook and small moorland settlements such as East Ilkerton, West Ilkerton and Shallowford. The South West Coast Path and Tarka Trail pass through, and the Two Moors Way runs from Ivybridge in South Devon to Lynmouth; the Samaritans Way South West runs from Bristol to Lynton, and the Coleridge Way from Nether Stowey to Lynmouth. Lynmouth was described by Thomas Gainsborough, who honeymooned there with his bride Margare ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Georges Darreius
Georges Jean Marie Darrieus (24 September 1888 – 15 July 1979) was a French aeronautical engineer in the 20th century. He is perhaps most famous for his invention of the Darrieus rotor, a wind turbine capable of operating from any direction and under adverse weather conditions, and the vertical-axis giromill The Darrieus wind turbine is a type of vertical axis wind turbine (VAWT) used to generate electricity from wind energy. The turbine consists of a number of curved aerofoil blades mounted on a rotating shaft or framework. The curvature of the bla ....

Darwin, Australia
Darwin ( ; Larrakia: ) is the capital city of the Northern Territory, Australia. With an estimated population of 147,255 as of 2019, the city contains the majority of the residents of the sparsely populated Northern Territory. It is the smallest, wettest, and most northerly of the Australian capital cities and serves as the Top End's regional centre. Darwin's proximity to Southeast Asia makes the city's location a key link between Australia and countries such as Indonesia and East Timor. The Stuart Highway begins in Darwin, extends southerly across central Australia through Tennant Creek and Alice Springs, concluding in Port Augusta, South Australia. The city is built upon a low bluff overlooking Darwin Harbour. Darwin's suburbs begin at Lee Point in the north and stretch to Berrimah in the east. The Stuart Highway extends to Darwin's eastern satellite city of Palmerston and its suburbs. The Darwin region, like much of the Top End, experiences a tropical climate with a wet an ...

Northern Ireland
Northern Ireland ( ga, Tuaisceart Éireann ; sco, label= Ulster-Scots, Norlin Airlann) is a part of the United Kingdom, situated in the north-east of the island of Ireland, that is variously described as a country, province or region. Northern Ireland shares an open border to the south and west with the Republic of Ireland. In 2021, its population was 1,903,100, making up about 27% of Ireland's population and about 3% of the UK's population. The Northern Ireland Assembly (colloquially referred to as Stormont after its location), established by the Northern Ireland Act 1998, holds responsibility for a range of devolved policy matters, while other areas are reserved for the UK Government. Northern Ireland cooperates with the Republic of Ireland in several areas. Northern Ireland was created in May 1921, when Ireland was partitioned by the Government of Ireland Act 1920, creating a devolved government for the six northeastern counties. As was intended, Northern Ireland ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

SeaGen
SeaGen was the world's first large scale commercial tidal stream generator. It was four times more powerful than any other tidal stream generator in the world at the time of installation. It was successfully decommissioned by SIMEC Atlantis Energy Limited in summer 2019, having exported 11.6GWh to the grid since 2008. The first SeaGen generator was installed in Strangford Narrows between Strangford and Portaferry in Northern Ireland. Strangford Lough was also the site of the first known tide mill in the world, the Nendrum Monastery mill where remains dating from 787 have been excavated. History Marine Current Turbines, the developer of SeaGen, demonstrated first prototype of tidal stream generator in 1994 with a 15 kilowatt system in Loch Linnhe, off the west coast of Scotland. In May 2003, the prototype for SeaGen, '', was installed off the coast of Lynmouth, North Devon, England. Seaflow was a single rotor turbine which generated 300 kW but was not conne ...

Roosevelt Island
Roosevelt Island is an island in New York City's East River, within the borough of Manhattan. It lies between Manhattan Island to the west, and the borough of Queens, on Long Island, to the east. Running from the equivalent of East 46th to 85th Streets on Manhattan Island, it is about long, with a maximum width of , and a total area of . Together with Mill Rock, Roosevelt Island constitutes Manhattan's Census Tract 238, which has a land area of , and had a population of 11,722 as of the 2020 United States Census. Lying below the Queensboro Bridge, the island cannot be accessed directly from the bridge itself. Vehicular traffic uses the Roosevelt Island Bridge to access the island from Astoria, Queens, though the island is not designed for vehicular traffic and has several areas designed as car-free zones. Several public transportation options to reach the island exist. The Roosevelt Island Tramway, the oldest urban commuter tramway in the U.S, connects the island to Man ...

Queens
Queens is a borough of New York City, coextensive with Queens County, in the U.S. state of New York. Located on Long Island, it is the largest New York City borough by area. It is bordered by the borough of Brooklyn at the western tip of Long Island to its west, and Nassau County to its east. Queens also shares water borders with the boroughs of Manhattan, the Bronx, and Staten Island (via the Rockaways). With a population of 2,405,464 as of the 2020 census, Queens is the second most populous county in the State of New York, behind Kings County (Brooklyn), and is therefore also the second most populous of the five New York City boroughs. If Queens became a city, it would rank as the fifth most-populous in the U.S. after New York City, Los Angeles, Chicago, and Houston. Approximately 47% of the residents of Queens are foreign-born. Queens is the most linguistically diverse place on Earth and is one of the most ethnically diverse counties in the United States. Queens was est ...
