Aguçadoura Wave Farm
The Aguçadoura Wave Farm was a wave farm located offshore near Póvoa de Varzim north of Porto in Portugal. The farm was designed to use three Pelamis Wave Energy Converters to convert the motion of the ocean surface waves into electricity, totalling to 2.25 MW in total installed capacity. The farm was officially opened on 23 September 2008, by the Portuguese Minister of Economy. The wave farm was shut down two months after the official opening in November 2008. Pelamis machines Developed by the Scottish company Pelamis Wave Power, the Pelamis machine is made up of connected sections which flex and bend relative to one another as waves run along the structure. This motion is resisted by hydraulic rams which pump high pressure oil through hydraulic motors which in turn drive electrical generators. The three machines which made up the Aguçadoura Wave Park were each rated at a peak output of 750 kW, giving an installed peak capacity of 2.25 MW, enough to meet th ...

Portugal
Portugal, officially the Portuguese Republic, In recognized minority languages of Portugal: :* mwl, República Pertuesa is a country located on the Iberian Peninsula, in Southwestern Europe, and whose territory also includes the Macaronesian archipelagos of the Azores and Madeira. It features the westernmost point in continental Europe, its mainland west and south border with the North Atlantic Ocean and in the north and east, the Portugal-Spain border, constitutes the longest uninterrupted border-line in the European Union. Its archipelagos form two autonomous regions with their own regional governments. On the mainland, Alentejo region occupies the biggest area but is one of the least densely populated regions of Europe. Lisbon is the capital and largest city by population, being also the main spot for tourists alongside Porto, the Algarve and Madeira. One of the oldest countries in Europe, its territory has been continuously settled and fought over since prehistoric tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cleantech
Clean technology, in short cleantech, is any process, product, or service that reduces negative environmental impacts through significant energy efficiency improvements, the sustainable use of resources, or environmental protection activities. Clean technology includes a broad range of technology related to recycling, renewable energy, information technology, green transportation, electric motors, green chemistry, lighting, grey water, and more. Environmental finance is a method by which new clean technology projects can obtain financing through the generation of carbon credits. A project that is developed with concern for climate change mitigation is also known as a carbon project. Clean Edge, a clean technology research firm, describes clean technology "a diverse range of products, services, and processes that harness renewable materials and energy sources, dramatically reduce the use of natural resources, and cut or eliminate emissions and wastes." Clean Edge notes that, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dow Jones News Service
Dow Jones & Company, Inc. is an American publishing firm owned by News Corp and led by CEO Almar Latour. The company publishes ''The Wall Street Journal'', '' Barron's'', ''MarketWatch'', ''Mansion Global'', ''Financial News'' and ''Private Equity News''. It formerly published the Dow Jones Industrial Average. History The company was founded in 1882 by three reporters: Charles Dow, Edward Jones, and Charles Bergstresser. Charles Dow was widely known for his ability to break down and convey what was often considered very convoluted financial information and news to the general public - this is one of the reasons why Dow Jones & Company is well known for their publications and transferring of important and sometimes difficult to understand financial information to people across the globe. Nevertheless, the three reporters were joined in control of the organization by Thomas F. Woodlock. Dow Jones was acquired in 1902 by Clarence Barron, the leading financial journalist of the ...

BBC Scotland
BBC Scotland (Scottish Gaelic: ''BBC Alba'') is a division of the BBC and the main public broadcaster in Scotland. It is one of the four BBC national regions, together with the BBC English Regions, BBC Cymru Wales and BBC Northern Ireland. Its headquarters are in Glasgow, it employs approximately 1,250 staff as of 2017, to produce 15,000 hours of television and radio programming per year. Some £320 million of licence fee revenue is raised in Scotland, with expenditure on purely local content set to stand at £86 million by 2016–17. The remainder of licence fee revenue raised in the country is spent on networked programmes shown throughout the UK. BBC Scotland operates television channels such as the Scottish variant of BBC One, the BBC Scotland channel and the Gaelic-language channel BBC Alba, and radio stations BBC Radio Scotland and Gaelic-language BBC Radio nan Gaidheal.

Electrical Generator
In electricity generation, a generator is a device that converts motive power (mechanical energy) or fuel-based power (chemical energy) into electric power for use in an external electrical circuit, circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even hand crank (mechanism), cranks. The first electromagnetic generator, the Faraday disk, was invented in 1831 by British scientist Michael Faraday. Generators provide nearly all of the power for electric power grids. In addition to electromechanical designs, photovoltaic and fuel cell powered generators utilize solar power and hydrogen-based fuels, respectively, to generate electrical output. The reverse conversion of electrical energy into mechanical energy is done by an electric motor, and motors and generators have many similarities. Many motors can be mechanically driven to generate electricity; frequently they make acceptable manual genera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydraulic Machinery
Hydraulic machines use liquid fluid power to perform work. Heavy construction vehicles are a common example. In this type of machine, hydraulic fluid is pumped to various hydraulic motors and hydraulic cylinders throughout the machine and becomes pressurized according to the resistance present. The fluid is controlled directly or automatically by control valves and distributed through hoses, tubes, or pipes. Hydraulic systems, like pneumatic systems, are based on Pascal's law which states that any pressure applied to a fluid inside a closed system will transmit that pressure equally everywhere and in all directions. A hydraulic system uses an incompressible liquid as its fluid, rather than a compressible gas. The popularity of hydraulic machinery is due to the very large amount of power that can be transferred through small tubes and flexible hoses, the high power density and a wide array of actuators that can make use of this power, and the huge multiplication of fo ...

Hydraulic Ram
A hydraulic ram, or hydram, is a cyclic water pump powered by hydropower. It takes in water at one " hydraulic head" (pressure) and flow rate, and outputs water at a higher hydraulic head and lower flow rate. The device uses the water hammer effect to develop pressure that allows a portion of the input water that powers the pump to be lifted to a point higher than where the water originally started. The hydraulic ram is sometimes used in remote areas, where there is both a source of low-head hydropower and a need for pumping water to a destination higher in elevation than the source. In this situation, the ram is often useful, since it requires no outside source of power other than the kinetic energy of flowing water. History The Alhambra, built by Nasrid Sultan Ibn al-Ahmar of Granada beginning AD1238, used a hydram to raise water. Through a first reservoir, filled by a channel from the Darro River, water emptied via a large vertical channel into a second reservoir b ...
