In the piece Tesla explains that the Van DE Graaff generator, developed in 1929, cannot create energy but that it can separate the charges within an atom to be stored and utilized later.
Any of various devices, including the electrophorus, the Wimshurst machine, and especially the Van DE Graaff generator, that generate high voltages by accumulating large quantities of electric charge.
