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 earlier, ma ...

Churchill Falls Generating Station
The Churchill Falls Generating Station is a hydroelectric underground power station in Labrador. At 5,428 MW, it is the sixteenth largest in the world, and the second-largest in Canada, after the Robert-Bourassa generating station in northwestern Quebec. Rather than a single large dam, the plant's reservoir is contained by 88 dykes, totalling 64 km in length. Now called the Smallwood Reservoir, it has a capacity of 33 cubic kilometres in a catchment area of about 72,000 square kilometres, an area larger than the Republic of Ireland. It drops over 305 metres to the site of the plant's 11 turbines. The plant's power house was hewn from solid granite 300 metres underground. It is about 300 metres long and as high as a 15-story building. The station cost almost a billion Canadian dollars to build in 1970. Commissioned from 1971 to 1974, it is owned and operated by the Churchill Falls Labrador Corporation Limited, a joint venture between Nalcor Energy (65.8%) and Hydro- ...

Hydro-Québec
Hydro-Québec is a public utility that manages the generation, transmission and distribution of electricity in the Canadian province of Quebec, as well as the export of power to portions of the Northeast United States. It was established by the Government of Quebec in 1944 from the expropriation of private firms. This was followed by massive investment in hydro-electric projects like the James Bay Project. Today, with 63 hydroelectric power stations, the combined output capacity is 37,370 megawatts. Extra power is exported from the province and Hydro-Québec supplies 10 per cent of New England's power requirements. Hydro-Québec is a Crown corporation (state-owned enterprise) based in Montreal. In 2018, it paid CAD$2.39 billion in dividends to its sole shareholder, the Government of Québec. Its residential power rates are among the lowest in North America. More than 40 percent of Canada’s water resources are in Québec and Hydro-Québec is the fourth largest hydropower produ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert-Bourassa Generating Station
The Robert-Bourassa generating station, formerly known as La Grande-2 (LG-2), is a hydroelectric power station on the La Grande River that is part of Hydro-Québec's James Bay Project in Canada. The station can generate 5,616 MW and its 16 units were gradually commissioned between 1979 and 1981. Annual generation is in the vicinity of 26500 GWh. Together with the adjacent 2,106 MW La Grande-2-A generating station (LG-2-A), commissioned in 1991–1992, it uses the reservoir and dam system of the Robert-Bourassa Reservoir to generate electricity. The two plants taken together account for more than 20% of Hydro-Québec's total installed capacity of 36,810 MW in 2009. It is Canada's largest hydroelectric power station, ranks in 12th place on the list of largest hydroelectric power stations and is the world's largest underground power station.

Pressurized Heavy-water Reactor
A pressurized heavy-water reactor (PHWR) is a nuclear reactor that uses heavy water ( deuterium oxide D2O) as its coolant and neutron moderator. PHWRs frequently use natural uranium as fuel, but sometimes also use very low enriched uranium. The heavy water coolant is kept under pressure to avoid boiling, allowing it to reach higher temperature (mostly) without forming steam bubbles, exactly as for pressurized water reactor. While heavy water is very expensive to isolate from ordinary water (often referred to as ''light water'' in contrast to ''heavy water''), its low absorption of neutrons greatly increases the neutron economy of the reactor, avoiding the need for enriched fuel. The high cost of the heavy water is offset by the lowered cost of using natural uranium and/or alternative fuel cycles. As of the beginning of 2001, 31 PHWRs were in operation, having a total capacity of 16.5 GW(e), representing roughly 7.76% by number and 4.7% by generating capacity of all current ope ...

Geographic Coordinate System
The geographic coordinate system (GCS) is a spherical or ellipsoidal coordinate system for measuring and communicating positions directly on the Earth as latitude and longitude. It is the simplest, oldest and most widely used of the various spatial reference systems that are in use, and forms the basis for most others. Although latitude and longitude form a coordinate tuple like a cartesian coordinate system, the geographic coordinate system is not cartesian because the measurements are angles and are not on a planar surface. A full GCS specification, such as those listed in the EPSG and ISO 19111 standards, also includes a choice of geodetic datum (including an Earth ellipsoid), as different datums will yield different latitude and longitude values for the same location. History The invention of a geographic coordinate system is generally credited to Eratosthenes of Cyrene, who composed his now-lost ''Geography'' at the Library of Alexandria in the 3rd century ...
