Electrostatic generator patent In 1935, a patent was issued to Robert Jemison Van de Graaff for his Electrostatic Generator design (U.S. No. 1,991,236), able to generate direct-current voltages much higher than the 700,000-V which was the state of the art at the time using other methods. It consisted of two large, hollow approximately spherical metal domes on insulated columns. A silk belt ran on rollers between the base of the column to the interior of the dome. Charges from a 5000-V source are transferred to the belt near the lower roller, carried upward and are collected by a metal comb connected to the dome interior. By nature, rather than accumulating on the interior, the charges move to the exterior of the dome. Two such domes with opposite charges could generate a potential difference of 1,500,000-V between them.
