Wave Power
Wave power is the capture of energy of wind waves to do useful work – for example, electricity generation, water desalination, or pumping water. A machine that exploits wave power is a wave energy converter (WEC). Waves are generated by wind passing over the sea's surface. As long as the waves propagate slower than the wind speed just above, energy is transferred from the wind to the waves. Air pressure differences between the windward and leeward sides of a wave crest and surface friction from the wind cause shear stress and wave growth. Wave power is distinct from tidal power, which captures the energy of the current caused by the gravitational pull of the Sun and Moon. Other forces can create currents, including breaking waves, wind, the Coriolis effect, cabbeling, and temperature and salinity differences. As of 2022, wave power is not widely employed for commercial applications, after a long series of trial projects. Attempts to use this energy began in 1890 or ...

Spiddal
Spiddal ( ga, An Spidéal , meaning 'the hospital') is a village on the shore of Galway Bay in County Galway, Ireland. It is west of Galway city, on the R336 road. It is on the eastern side of the county's Gaeltacht (Irish-speaking area) and of the Connemara region. According to the 2016 census, 35.3% of the population speak Irish on a daily basis outside the education system. It is a centre for tourism with a beach, harbour, and shore fishing. The village is part of the civil parish of Moycullen. Name The name of the village in Irish, ''An Spidéal'', derives from the word ''ospidéal'', in turn derived from the English word 'hospital'. A number of hospital facilities were based in the area, including a famine hospital which was located in Spiddal during the Great Famine of the mid-1840s. While 'Spiddal' is the common English variant of the name, 'Spiddle' is sometimes used. History Spiddal like much of the west of Ireland suffered greatly during the Great Famine, wi ...

Wavebob
Wavebob was a wave energy converter which was in development between 1999 and 2013 when the company was closed owing to funding difficulties. The device was an axisymetric self-reacting heaving buoy point absorber. It consisted of two oscillating structures, a floating collar or torus which followed the motion of the waves, and a central section containing the power-take-off at the top and a buoyancy-controlling tank below the water. Wavebob Ltd. commenced the first of a number of sea trials in Galway Bay in Ireland during which it was tested as a 1/4 scale device for short periods at the SEAI 1/4 Scale Wave Power Testing facility which is located in the inner bay inside the natural Aran Islands breakwater and where devices under test are exposed to around 1/3 of the expected energy of the 'Full Atlantic Ocean'. Technology Wavebob used the lift and fall of ocean waves to drive generators The Wavebob consisted of two oscillating structures. These structures must be able ...

Vigor Shipyards
Vigor Shipyards is the current entity operating the former Todd Shipyards after its acquisition in 2011. Todd Shipyards was founded in 1916, which owned and operated shipyards on the West Coast of the United States, East Coast of the United States and the Gulf. Todd Shipyards were a major part of the Emergency Shipbuilding Program for World War II. Vigor Shipyards In February 2011, Vigor Industrial purchased Todd for US$130 million. This included the Seattle, Everett and Bremerton operations. Today, Vigor Shipyards is a government repair subsidiary of Vigor Industrial. Originally, the Coast Guard wanted to acquire 25 Offshore Patrol Cutters (OPC) and spend about $8 billion for them. In April 2013, it was reported that Vigor proposed an Ulstein X-bow hull in the design competition for the OPC vessels. If successful in landing the contract, Vigor would have assembled the vessels at its Portland, Ore., shipyard. However, in February 2014, the USCG announced that Bollinger Shipy ...

Oregon
Oregon () is a state in the Pacific Northwest region of the Western United States. The Columbia River delineates much of Oregon's northern boundary with Washington, while the Snake River delineates much of its eastern boundary with Idaho. The 42° north parallel delineates the southern boundary with California and Nevada. Oregon has been home to many indigenous nations for thousands of years. The first European traders, explorers, and settlers began exploring what is now Oregon's Pacific coast in the early-mid 16th century. As early as 1564, the Spanish began sending vessels northeast from the Philippines, riding the Kuroshio Current in a sweeping circular route across the northern part of the Pacific. In 1592, Juan de Fuca undertook detailed mapping and studies of ocean currents in the Pacific Northwest, including the Oregon coast as well as the strait now bearing his name. Spanish ships – 250 in as many years – would typically not land before reaching Cape M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Union
The European Union (EU) is a supranational political and economic union of member states that are located primarily in Europe. The union has a total area of and an estimated total population of about 447million. The EU has often been described as a ''sui generis'' political entity (without precedent or comparison) combining the characteristics of both a federation and a confederation. Containing 5.8per cent of the world population in 2020, the EU generated a nominal gross domestic product (GDP) of around trillion in 2021, constituting approximately 18per cent of global nominal GDP. Additionally, all EU states but Bulgaria have a very high Human Development Index according to the United Nations Development Programme. Its cornerstone, the Customs Union, paved the way to establishing an internal single market based on standardised legal framework and legislation that applies in all member states in those matters, and only those matters, where the states have agree ...

Beaufort Scale
The Beaufort scale is an empirical measure that relates wind speed to observed conditions at sea or on land. Its full name is the Beaufort wind force scale. History The scale was devised in 1805 by the Irish hydrographer Francis Beaufort (later Rear Admiral), a Royal Navy officer, while serving on . The scale that carries Beaufort's name had a long and complex evolution from the previous work of others (including Daniel Defoe the century before) to when Beaufort was Hydrographer of the Navy in the 1830s, when it was adopted officially and first used during the voyage of HMS ''Beagle'' under Captain Robert FitzRoy, who was later to set up the first Meteorological Office (Met Office) in Britain giving regular weather forecasts. In the 18th century, naval officers made regular weather observations, but there was no standard scale and so they could be very subjective – one man's "stiff breeze" might be another's "soft breeze". Beaufort succeeded in standardising the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oscillating Water Column
Oscillating water columns (OWCs) are a type of wave energy converter that harness energy from the oscillation of the seawater inside a chamber or hollow caused by the action of waves. OWCs have shown promise as a renewable energy source with low environmental impact. Because of this, multiple companies have been working to design increasingly efficient OWC models. OWC are devices with a semi-submerged chamber or hollow open to the sea below, keeping a trapped air pocket above a water column. Waves force the column to act like a piston, moving up and down, forcing the air out of the chamber and back into it. This continuous movement forces a bidirectional stream of high-velocity air, which is channeled through a power take-off (PTO). The PTO system converts the airflow into energy. In models that convert airflow to electricity, the PTO system consists of a bidirectional turbine. This means that the turbine always spins the same direction regardless of the direction of airflow, all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
