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 the run of a 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 least ecologically damaging among the Tidal power#Methods, four main forms of tid ...

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. Oceanflow Energy Ltd was formed in 2001, based in North Shields, Tyne And Wear near Newcastle upon Tyne. Several small-scale prototypes have been tested between 2006 and 2017. 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 consis ...

Clarence Strait (Northern Territory)
Clarence Strait in northern Australia Australia, officially the Commonwealth of Australia, is a country comprising mainland Australia, the mainland of the Australia (continent), Australian continent, the island of Tasmania and list of islands of Australia, numerous smaller isl ... separates Melville Island from the mainland of Australia. It also connects the Beagle Gulf in the west to the Van Diemen Gulf in the east. It is approximately 50 km (31 mi) north of the city of Darwin. Administrative status On 4 April 2007, most of the area occupied by the Clarence Strait was gazetted by the Northern Territory Government as a locality with the name, Vernon Islands. The locality has not been added to any existing local government area and is considered to be part of the Northern Territory's unincorporated areas.

Darwin, Australia
Darwin (Laragiya language, Larrakia: ') is the List of Australian capital cities, capital city of the Northern Territory, Australia. The city has nearly 53% of the Northern Territory's population, with 139,902 at the 2021 Australian census, 2021 census. 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 it a key link between Australia and countries such as Indonesia and Timor-Leste. The Stuart Highway begins in Darwin and 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 extend to Lee Point, Northern Territory, Lee Point in the north and to Berrimah, Northern Territory, Berrimah in the east. The Stuart Highway extends to Darwin's eastern satellite city of Palmerston, Northern Territory, Palmerston and it ... [...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 decommissioned by SIMEC Atlantis Energy Limited in summer 2019, having exported 11.6 GWh 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 CE have been excavated. History Marine Current Turbines, the developer of SeaGen, demonstrated its first prototype of a 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 ...

Roosevelt Island
Roosevelt Island is an island in New York City's East River, within the Borough (New York City), borough of Manhattan. It lies between Manhattan Island to the west, and the borough of Queens, on Long Island, to the east. It is about long, with an area of , and had a population of 11,722 as of the 2020 United States census. It consists of two largely residential communities: Northtown and Southtown. Roosevelt Island is owned by the city but was leased to the New York State Urban Development Corporation (UDC) for 99 years in 1969. The island was called by the Lenape and (Hog Island) by the New Netherlander, Dutch during the colonial era and later Blackwells Island. During much of the 19th and 20th centuries, the island was used by hospitals and prisons, with very limited access. It was renamed Welfare Island in 1921. Following several proposals to redevelop Welfare Island in the 1960s, the UDC leased the island, renamed it after former U.S. president Franklin D. Roosevelt in 1 ...

Queens
Queens is the largest by area of the Boroughs of New York City, five boroughs of New York City, coextensive with Queens County, in the U.S. state of New York (state), New York. Located near the western end of Long Island, it is bordered by the borough of Brooklyn and by Nassau County, New York, Nassau County to its east, and shares maritime borders with the boroughs of Manhattan, the Bronx, and Staten Island, as well as with New Jersey. Queens is one of the most linguistics, linguistically and ethnically diverse places in the world. With a population of 2,405,464 as of the 2020 United States census, 2020 census, Queens is the second-most populous county in New York state, behind Kings County (Brooklyn), and is therefore also the second-most populous of the five New York City boroughs. If Queens were its own city, it would be the List of United States cities by population, fourth most-populous in the U.S. after the rest of New York City, Los Angeles, and Chicago.

East River
The East River is a saltwater Estuary, tidal estuary or strait in New York City. The waterway, which is not a river despite its name, connects Upper New York Bay on its south end to Long Island Sound on its north end. It separates Long Island, with the boroughs of Brooklyn and Queens, from Manhattan Island, and from the Bronx on the North American mainland. The East River forms the eastern boundary of Manhattan Island, whereas the island's western boundary is formed by the Hudson River.Hodges, Godfrey. "East RIver" in Jackson, pp.393–93 Because of its connection to Long Island Sound, it was once also known as the ''Sound River''. The tidal strait changes its direction of flow regularly, and is subject to strong fluctuations in its current, which are accentuated by its narrowness and variety of depths. The waterway is navigable for its entire length of , and was historically the center of maritime activities in the city. Formation and description Technically a Ria, drowned va ...

Verdant Power
Verdant Power, Inc is a maker and installer of tidal power and hydroelectric systems. Their primary device is an underwater turbine, similar to a three-bladed wind turbine, that is designed to capture energy from tidal currents and (precipitation-driven) river currents. The company uses the trade term "kinetic hydropower" to distinguish their systems from those (tidal and hydroelectric) based on dam construction. The company's first project, the Roosevelt Island Tidal Energy Project, is several turbines in New York City's East River. Location Verdant's home base is situated between Manhattan and Queens on Roosevelt Island in the middle of the East River, a tidal strait running from Long Island Sound to Upper New York Bay.Powering the Future Underwat ...
