To explain the fact that objects close to the surface of the Earth are more attracted than repulsed, we owe to admit that a high layer in the atmosphere repulses whatthe solid portion of the Earth attracts. The phenomenon of the the tail of the comets repulsed from the sun, of polar light, of zodiacal light will find here their explanation. Also water, in small drops, is lifted then dropped by electrical charges and discharges. The radio-layer in the atmosphere is probably the attracting and repulsing medium acting contrary to the ground. The moving of negative electricity into the ground does is due to the charge of the Earth.
Levitation is conceivable.
Perpetuum mobile theroretically possible. Discharge from upper layer might be exploited, also with destructive purposes. A flight to interplanetary space in defiance of gravitation is thinkable. Electrical charges in the Earth and its atmosphere are chiefly induced and sent by the Sun. Sun sends two kinds of charges, positive and negative.
