[TCML] Kentucky Fried Spark Gap

"Another device, entirely automatic, and, probably suitable for use in suburban districts, comprises two insulated metal plates, supported in any convenient manner, in close proximity to each other. These plates are connected through the primary of an induction coil with the determinals of a generator, and are bridged by two movable contacts joined by a flexible cable. The two contacts are both attached to the legs of a good-sized chicken standing astride on the plates. Heat being applied to the latter, muscular contractions are produced in the legs of the chicken, which thus makes and breaks the current through the induction coil. Any number, of such chickens may be provided and the contacts connected in series or multiple arc, as may be desired, thus, increasing the frequency of the impulses."
