<p>Provided is an apparatus for inducing electric current by winding a wire around a crystal or the like. A small amount of a laser beam (red or the like) is irradiated to the crystal to generate oscillation inside the crystal, and accordingly, a large amount of current is induced in the wire or the like installed around the same due to the activity of an oscillator. The induced current operates various electromechanical apparatuses whose energy source is external electricity.</p> |
