Tandem Van de Graaff generators are essentially two generators in series and can produce about 15 MV. The Van de Graaff generator is a simple mechanical device. Small Van de Graaff generators are built by hobbyists and scientific apparatus companies and are used to demonstrate the effects of high DC potentials.
John Ernst Worrell Keely (September 3, 1837 – November 18, 1898) was an American fraudster and self-proclaimed inventor from Philadelphia who claimed to have discovered a new motive power which was initially described as "vaporic" or "etheric" force, and later as an unnamed force based on "vibratory sympathy", by which he produced "interatomic ether" from water and air.
