Charles Francis Brush was an American engineer, inventor, businessman and philanthropist. He is credited with the invention of the first electric generator in history. The generator is a device that converts mechanical energy into electrical energy for use in an external circuit. The first electromagnetic generator, the Faraday disk, was invented in 1831 by British scientist Michael Faraday.
This simple, basic device revolutionized almost every aspect of people's lives around the world. It works by converting the driving force (mechanical energy), in this case, the movement of the magnet moving back and forth, into electricity. Generators provide almost all the energy for power grids. Many motors can be mechanically driven to generate electricity; they often make manual generators acceptable.
A power plant, also known as a power station or generating station, is an industrial facility for generating electrical energy. In Canada alone, and in 1888, approximately 200 electric companies depended on hydropower for at least part of their electricity generation. Around the same time that hydropower was gaining popularity, inventors were also discovering how to use windmills of the past to generate electricity for the future. For example, in the 1870s Siemens used electromagnetic dynamos to power electric arc furnaces for the production of metals and other materials. Ferranti designed the Deptford power plant for the London Electric Supply Corporation in 1887 using an alternating current system.
In 1896, about a decade after Charles Parsons developed his steam turbine generator, American inventor Charles Curtis offered a different turbine invention to General Electric Co. Most power plants contain one or more generators, a rotating machine that converts mechanical energy into three-phase electrical energy. A homopolar generator is a DC electrical generator comprising an electrically conductive disc or cylinder that rotates in a plane perpendicular to a uniform static magnetic field. The idea was to divert part of the electricity produced by the generator to the wires of the electromagnets. Before the connection between magnetism and electricity was discovered, electrostatic generators were invented.
Until about the 1960s, motor vehicles tended to use DC generators (dynamos) with electromechanical regulators. Charles Francis Brush is credited with inventing the first electric generator in history. This revolutionary device has changed our lives forever and continues to be used in many aspects of our lives today. It has enabled us to generate electricity from various sources such as hydropower and windmills and has allowed us to power our homes and businesses.
