In the broadest sense of the word, energy is a substance’s capacity to do work or produce an effect, such as burning coal to create heat. Canada is home to vast quantities of both renewable (e.g. wind) and non-renewable energy sources (e.g. oil). This collection gathers all of The Canadian Encyclopedia’s articles relating to energy, from various types to the means by which they are sourced.
High above the St. Lawrence River, on a hot August day in 1907, a worker named Beauvais was driving rivets into the great southern span of the Quebec Bridge. Near the end of a long day, he noticed that a rivet that he had driven no more than an hour before had snapped clean in two.
The aerospace industry includes the development and production of aircraft, satellites, rockets and their component parts. Aerospace is a major component of Canada's economy, employs tens of thousands of Canadians, and accounts for a large part of Canadian trade with foreign markets. Canada boasts a diverse aerospace sector and is one of just a few countries that produce airplanes. Through close partnership with the United States space agency, the National Aeronautics and Space Administration (NASA), Canada has also launched satellites as well as built sophisticated components used on the International Space Station.
The Canadarm was a remote-controlled mechanical arm, also known as the Shuttle Remote Manipulator System (SRMS). During its 30-year career with NASA’s Space Shuttle Program, the robotic arm deployed, captured and repaired satellites, positioned astronauts, maintained equipment, and moved cargo.
Zamboni ice resurfacers are used in arenas across Canada and around the world. Although Zamboni is a registered trademark, many Canadians use the term to refer to all ice resurfacers, including those produced by other companies. American Frank J. Zamboni invented the original Zamboni ice resurfacer in 1949. His namesake company is based in Paramount, California, but also has a large manufacturing facility in Brantford, Ontario. The Zamboni Company’s major competitor, Resurfice Corporation (based in Elmira, Ontario), produces the Olympia line of ice resurfacers that are used in arenas across Canada and around the world. In 2016, ICETECH Machines began producing the Okay Elektra, an electronic ice resurfacer, in Terrebonne, Québec.
The Canadian Science and Engineering Hall of Fame is a permanent exhibition at the Canada Science and Technology Museum that honours individuals whose outstanding scientific or technological achievements have had long-term implications for Canadians.
Chemical manufacturing entails the conversion of one material to another by a chemical reaction on a commercial scale. The starting material (feedstock) can be a natural substance or a relatively pure chemical used as an "intermediate" for subsequent upgrading.
Each mineral species is identified by its own appellation, and names have been assigned since antiquity. While there are only some 3000 valid mineral species, nearly 20 000 names occur in the literature. This is partly because researchers working independently have given different names to the same mineral, and partly because distinct names have been applied to minerals that later proved to be varieties or mixtures of already known species. Today a much better control is exercised by the Commission on New Minerals and New Mineral Names established in 1959 by the International Mineralogical Association.
In North America in precontact times, Indigenous people hand-ground corn and other substances (eg, acorns) into flour used in porridge, flat cakes, etc. By the middle of the 16th century, the first European settlers had arrived in New France, bringing with them their flour milling technology.
Although Canada's tobacco industry has developed largely during this century, tobacco growing goes back to early colonial days, when settlers around the St Lawrence River adopted the smoking customs of aboriginal peoples. French settlers began by copying the agricultural model set by the Indians.
In 1971, Hydro-Québec and the Québec government initiated the James Bay Project, a monumental hydroelectric-power development on the east coast of James Bay. Over the course of two phases they built a total of eight generating stations, allowing for the pollution-free production of a significant portion of Québec's electricity. However, the projects also profoundly disrupted the environment and the Indigenous communities living in the region, the effects of which are still felt today.
