T T 3 Sub Sphic. vantages which have here tofore existed in such systems of main transmission of signals or intelligence is the object of my present invention, which comprises a novel method of accomplishing these ends. The method, briefly stated, consists in producing arbitrarily varied or intermittent disturbances or effects, transmitting such disturbances or effects through the natural media to a distant receiving station, utilizing energy derived from such disturbances or effects at the rec iving station to charge xxxxxxxxxxxxx a condenser, and using the accumulated potential energy so obtained to operate a receiving device. An apparatus by means of which this method may be practiced is illustrated in the drawings hereto annexed, in which and Fi is a diagrammatic illustration of the apparatus (Fig. 2 is a modified form or arrangement of the same. In the practical application of my method I usually proceed as follows: At any two points in the transmitting medium, between which there exists, or may be obtained in any manner, through the action of the disturbances or effects to be invest igated or utilized, a difference of electrical potential of any magnitudo, I arrange two plates or electrodes so that they may be oppositely charged through the agency of such effects or disturbances, and I connect these electrodes to the terminals of a highly insulated condensar, generally of considerable capacity.
