A van de Graaff electrostatic generator charges a metal sphere to a high voltage using a moving belt of non-conductive material that carries a positive charge acquired by friction or an external source. The charge is carried by the belt into the interior of the ball, removed and carried to its surface, while the discharged part of the belt returns to a new charge.<\/p>\n
