"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."
-- Nikola Tesla, Electrical Review, March 15, 1899
