Wintertype electric machine.
An electrostatic generator, or electrostatic machine, is a mechanical device that produces static electricity, or electricity at high voltage and low continuous current. In case of the ‘winter’ type a glass disk is rubbed and it charges. Metallic combs transfer the charges to a insulated conductor. Electrostatic generators operate by using manual (or other) power to transform mechanical work into electric energy. Dimensions: 26 x 81 52cm..
