The Georgetown Steam Plant, a surprisingly complete and operable steam power plant after a career of nearly seventy-five years, was built in the early 1900s when Seattle's inexpensive hydroelectric power attracted manufacturers. Much of the power produced at this plant operated the streetcars. It marks the beginning of the end of the reciprocating steam engine's domination in the growing field of electrical energy generation for lighting and power.
The Decew Falls Hydro-Electric Development was a pioneering project in the generation and transmission of electrical energy at higher voltages and at greater distances in Canada. On 25 August 1898 this station transmitted power at 22,500 Volts, 66 2/3 Hz, two-phase, a distance of 56 km to Hamilton, Ontario. Using the higher voltage permitted efficient transmission over that distance. The Cataract Power Company of Hamilton Limited (the predecessor to the Dominion Power and Transmission Company) was organized in 1896.
The 1992 Nobel Prize in physics was awarded to Georges Charpak, France, for his invention and development of detectors in high energy physics. Since 1959 Charpak had worked at CERN, the European laboratory for particle physics situated in the canton of Geneva in Switzerland. Charpak invented the multi - wire proportional chamber at CERN. The pioneering work was published in 1968. Largely due to his work particle physicists have been able to focus their interest on very rare particle interactions, which often reveal the secrets of the inner parts of matter.
The Bonneville Dam, Columbia River Power and Navigation System consists of 55 major projects on Oregon's Columbia River and is said to be the largest hydroelectric system in the world.
The Columbia River forms part of the border between Washington and Oregon and flows inland through the only waterway that crosses the Cascade Mountains. To harness the energy of the ninth longest river in North America, engineers developed unique design and construction approaches to overcome problems caused by depth of water, current velocity, and an irregularly-shaped river bottom.
This was a pioneering venture in mainline railroad electrification. It established single-phase alternating current as a technical and economical alternative to direct current. This concept exerted considerable influence over subsequent systems both in the United States and abroad. The major components of the system were developed by the engineering staffs of the New York, New Haven & Hartford Railroad and the Westinghouse Electric and Manufacturing Company of East Pittsburgh, Pennsylvania.
