The largest air-insulated Van de Graaff generator in the world, built by Dr. Van de Graaff in the 1930s, is now displayed permanently at Boston's Museum of Science. With two conjoined 4.5 m (15 ft) aluminium spheres standing on columns 22 ft (6.7 m) tall, this generator can often obtain 2 MV (2 million volts).
Electrostatic machines are typically used in science classrooms to safely demonstrate electrical forces and high voltage phenomena. The elevated potential differences achieved have been also used for a variety of practical applications, such as operating X-ray tubes, particle accelerators, spectroscopy, medical applications, sterilization of food, and nuclear physics experiments.
An engineering drawing of a Wimshurst machine, from Hawkins Electrical Guide Wimshurst machine in operation Quadruple sector-less Wimshurst machine. The Wimshurst machine or Wimshurst influence machine is an electrostatic generator, a machine for generating high voltages developed between 1880 and 1883 by British inventor James Wimshurst (1832–1903).
Machines that generated static electricity with a glass disc were popular and widespread in Europe by 1740. [3] In 1745, German cleric Ewald Georg von Kleist and Dutch scientist Pieter van Musschenbroek discovered independently that the electric charge from these machines could be stored in a Leyden jar , named after the city of Leiden in the ...
Bagger 288 (Excavator 288), previously known as the MAN TAKRAF RB288 [2] built by the German company Krupp for the energy and mining firm Rheinbraun, is a bucket-wheel excavator or mobile strip mining machine. When its construction was completed in 1978, Bagger 288 superseded Big Muskie as the heaviest land vehicle in the world, at 13,500 tons. [3]
Before mains electricity and the formation of nationwide power grids, stationary engines were widely used for small-scale electricity generation.While large power stations in cities used steam turbines or high-speed reciprocating steam engines, in rural areas petrol/gasoline, paraffin/kerosene, and fuel oil-powered internal combustion engines were cheaper to buy, install, and operate, since ...
Bucyrus-Erie was an American surface and underground mining equipment company. It was founded as Bucyrus Foundry and Manufacturing Company in Bucyrus, Ohio, in 1880.Bucyrus moved its headquarters to South Milwaukee, Wisconsin, in 1893.
