Evopod
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 proportion ...

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. ...

Tees Barrage
The Tees Barrage is a barrage and road bridge across the River Tees, Northern England, just upriver of Blue House Point and is used to control the flow of the river, preventing flooding and the effects of tidal change. It is between the towns of Stockton-on-Tees and Thornaby, road access is only by the latter with limited road access to the Tees's north bank. The Tees Barrage comprises a river barrage, road bridge, footbridge, barge lock, fish pass and access point to a white water course. The waters above the barrage are permanently held at the level of an average high tide and are used for watersports such as canoeing, jet skiing, dragonboat racing and incorporates a 1 km rowing course. The Tees Barrage and Tees Barrage International White Water Course were developed by the defunct Teesside Development Corporation. Design The concrete base of the barrage is 70 m wide, 32 m long, and 5 m thick; it is supported by five concrete piers. In between the ...

Wind Wave
In fluid dynamics, a wind wave, water wave, or wind-generated water wave, is a surface wave that occurs on the free surface of bodies of water as a result from the wind blowing over the water surface. The contact distance in the direction of the wind is known as the ''fetch''. Waves in the oceans can travel thousands of kilometers before reaching land. Wind waves on Earth range in size from small ripples, to waves over high, being limited by wind speed, duration, fetch, and water depth. When directly generated and affected by local wind, a wind wave system is called a wind sea. Wind waves will travel in a great circle route after being generated – curving slightly left in the southern hemisphere and slightly right in the northern hemisphere. After moving out of the area of fetch, wind waves are called '' swells'' and can travel thousands of kilometers. A noteworthy example of this is waves generated south of Tasmania during heavy winds that will travel across the Pacif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portaferry
Portaferry () is a small town in County Down, Northern Ireland, at the southern end of the Ards Peninsula, near the Narrows at the entrance to Strangford Lough. It is home to the Exploris aquarium and is well known for the annual Gala Week Float Parade. It hosts its own small Marina, the Portaferry Marina. The Portaferry - Strangford Ferry service operates daily at 30-minute intervals (7.45 am to 10.45 pm) between the villages of Portaferry and Strangford, less than 1500 metres apart, conveying about 500,000 passengers per annum. It had a population of 2,514 people in the 2011 Census. Pot fishing, mainly for prawns and crabs and licensed shellfish farming takes place within Strangford Lough. Queen's University of Belfast have a Marine Research Laboratory on the shorefront and currently the town is also home to a tidal energy research project the Minesto Sea Kite. The lough is one of the world's most important marine sites with over 2,000 marine species. There are fine Georgia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Water Column
A water column is a conceptual column of water from the surface of a sea, river or lake to the bottom sediment.Munson, B.H., Axler, R., Hagley C., Host G., Merrick G., Richards C. (2004).Glossary. ''Water on the Web''. University of Minnesota-Duluth. Retrieved 27 May 2014. Descriptively, the deep sea water column is divided into five parts—'' pelagic zones'' (from Greek πέλαγος (pélagos), 'open sea')—from the surface to below the floor, as follows: ''epipelagic'', from the surface to 200 meters below the surface; ''mesopelagic'', from 200 to 1000 meters below the surface; '' bathypelagic'', from 1000 to 4000 meters below the surface; ''abyssopelagic'', from 4000 meters below the surface to the level sea floor; ''hadopelagic'', depressions and crevices below the level sea floor. The concept of water column is useful since many aquatic phenomena are explained by the incomplete vertical mixing of waters with discrete chemical, physical or biological characteristics. Fo ...
