this sounds like tesla impulse DC. do you have any more you could mention on quickly switching on/off, by accident or by others? Tesla got heat, cold, ozone, ambient light and fog out of his switch on/off escapades, getting a specific high frequency of DC interruptions (stop/start).. read the ozone apparatus patent and look at the claims. seriously.
APPARATUS FOR PRODUCING OZONE. SPECIFICATION forming part of Letters Patent No. 588,177, dated September 22, 1896. Application filed June 17, 1896. Serial No. 595,927. (No. model.) http://tesla.hu/tesla/patents/p-568177.068/index.htm ...In my present improvement I have utilized appliances of this general character under conditions and in combination with certain instrumentalities, hereinafter described, which enable me to produce without difficulty and at very slight expense, ozone in any desired quantities. I would state the apparatus which I have devised for this purpose *is capable of other and highly important uses of a similar nature*, so but for purposes of the present case I deem it sufficient to describe its operation and effects when used for the purpose of generating ozone.... ... What I claim as my invention is— 1. The combination with a circuit of direct currents, of a controller for making and breaking the same, a motor included in or connected with said circuit so as to increase its self-induction, and driving the said, controller, a condenser in a circuit around the controller, and a transformer through the primary of which the condenser discharges, as set forth. 2. The combination with a circuit of direct currents, of a controller for making and breaking the same, a series-wound motor having its coils included in said circuit and driving 40 the said controller, a condenser connected with the circuit around the point of interruption therein, and a transformer, the primary of which is in the discharge-circuit of the condenser, as set forth. 45 3. A device for producing ozone comprising in combination, surfaces between which an electrical discharge takes place, a transformer for producing the potential necessary for such discharge, a condenser in the primary circuit 55 of the transformer, a charging circuit, means 50 for charging the condenser by such circuit and discharging it through the primary of the transformer, and a device for maintaining a current of air between the discharge-surfaces, as set forth. 4. A device for producing ozone comprising in combination, surfaces between which an electrical discharge takes place, a transformer for producing the potential necessary for such discharge, a condenser in the primary circuit 6o of the transformer, a charging-circuit, means for charging the condenser by such circuit and discharging it through the primary of the transformer, a motor operated by the charging-circuit, and a device operated thereby 65 for maintaining a current of air between the discharge-surfaces, as set forth. 5. A device for producing ozone comprising in combination, surfaces between which an electrical discharge takes place, a transformer 70 for producing the potential necessary for such discharge, a condenser in the primary circuit of the transformer, a charging-circuit, a circuit-controller effecting the charging and discharging of the condenser, and a fan-motor connected with the charging-circuit and operating the circuit-controller and adapted to maintain a current of air between the discharge-surfaces, as set forth. 6. A device for producing ozone comprising in combination, means for charging a condenser, a circuit of low self-induction and resistance into which the condenser discharges, a coil for raising the potential of such discharge, and means for passing a current of 85 air through the high-potential discharge, as set forth.
