An electrostatic generator, or electrostatic machine, is an electrical generator that produces static electricity, or electricity at high voltage and low continuous current. The knowledge of static electricity dates back to the earliest civilizations, but for millennia it remained merely an interesting and mystifying phenomenon , without a ...
The Van de Graaff generator was developed, starting in 1929, by physicist Robert J. Van de Graaff at Princeton University, with help from colleague Nicholas Burke. The first model was demonstrated in October 1929. [7] The first machine used an ordinary tin can, a small motor, and a silk ribbon bought at a five-and-dime store. After that, he ...
Francis Hauksbee developed a more advanced electrostatic generator around 1704 using a glass bulb that had a vacuum. He later replaced the globe with a glass tube of about 2.5 feet (0.76 m) emptied of air. [1] The glass tube was a less effective static generator than the globe, but it became more popular because it was easier to use. [2]
It was the first industrial Van de Graaff generator in the world, [9] and marked the beginning of nuclear research for civilian applications. [10] [11] Built in 1937, it was a 65-foot-tall (20 m) pear-shaped tower. [9] [12] It was essentially unused after World War II, and the main structure was laid on its side in 2015. [12]

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).
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]
COSI, the Center of Science and Industry, opened to the public on March 29 1964, with the original location on East Broad Street in downtown Columbus.
Owing to their simpler design, electrostatic types were the first particle accelerators. The two most common types are the Van de Graaf generator invented by Robert Van de Graaff in 1929, and the Cockcroft-Walton accelerator invented by John Cockcroft and Ernest Walton in 1932. The maximum particle energy produced by electrostatic accelerators ...
