Text: "Operation of electric motors from atmospheric electric field." An electret-type electrostatic motor and a corona-type electrostatic motor have been constructed for operation from the earth electric field. The power is delivered to the motors by means of earth-field antennas. Results of the operation of the motors are reported. American Journal of Physics. 39(70, July 1971. p. 776-778.
