Abstract
An electromagnetic power generator for installation in the interior of a vehicular tire, working on the principle of deriving energy from the fact that a portion of the tire becomes flattened once every revolution, causing a change in the length of the corresponding chord. A small closed magnetic circuit is alternately opened and closed by this movement, by means of a flexible strap coupled between the tire interior and the magnetic circuit. The circuit is reclosed by magnetic attraction.
