A magnetohydrodynamic generator directly extracts electric power from moving hot gases through a magnetic field, without the use of rotating electromagnetic machinery. MHD generators were originally developed because the output of a plasma MHD generator is a flame, well able to heat the boilers of a steam power plant. The first practical design ...
Van de Graaff was the inventor of the Van de Graaff generator, a device which produces high voltages. During 1929, he developed his first such generator, producing 80,000 volts. [6] By 1933, he had constructed a larger generator generating 7 million volts. [6]
German scientist Johann Philipp Reis invented the microphone. 1862: Scottish physicist James Clerk Maxwell published the four equations bearing his name. 1866: The Transatlantic telegraph cable: 1873: Belgian engineer Zenobe Gramme who developed the DC generator accidentally discovered that a DC generator also works as a DC motor during an ...
James Wimshurst (13 April 1832 – 3 January 1903) was an English inventor, engineer and shipwright.Though Wimshurst did not patent his machines and the various improvements that he made to them, his refinements to the electrostatic generator led to its becoming widely known as the Wimshurst machine.
"Dynamo Electric Machine" (end view, partly section, U.S. patent 284,110) A dynamo is an electrical generator that creates direct current using a commutator.Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later electric-power conversion devices were based, including the electric motor, the alternating-current ...
The modern steam turbine, invented by Sir Charles Parsons in 1884, currently generates about 80% of the electric power in the world using a variety of heat sources. Turbine types include: Steam Water is boiled by coal burned in a thermal power plant. About 41% of all electricity is generated this way. [15]
Other variations were also invented for physics research, such as the Pelletron, that uses a chain with alternating insulating and conducting links for charge transport. Small Van de Graaff generators are commonly used in science museums and science education to demonstrate the principles of static electricity. A popular demonstration is to ...
The three also invented the modern power distribution system: Instead of former series connection they connect transformers that supply the appliances in parallel to the main line. The first demonstrative long-distance (34 km, 21 mi) AC line was built for the 1884 International Exhibition of Turin, Italy .
