A Van de Graaff particle accelerator in a pressurized tank at Pierre and Marie Curie University , Paris The concept of an electrostatic generator in which charge is mechanically transported in small amounts into the interior of a high-voltage electrode originated with the Kelvin water dropper , invented during by William Thomson Lord Kelvin ,  in which charged drops of water fall into a bucket with the same polarity charge, adding to the charge. Kelvin himself first suggested using a belt to carry the charge instead of water. The first electrostatic machine that used an endless belt to transport charge was constructed during by Augusto Righi.
