Energy conversion apparatus
An apparatus for maintaining the speed of rotation of a windmill rotor at a fixed ratio to the free flow velocity of the driving wind. This arrangement permits the windmill rotor to rotate at the speed at which its power output is maximized. The apparatus includes a plurality of interleaved rotating and stationary friction discs which convert the rotational kinetic energy of the windmill rotor shaft into thermal energy. An anemometer shaft, which rotates with a velocity which is proportional to the ambient wind velocity, drives a gear train which increases or decreases the pressure on the friction discs so that the load on the rotor is increased or decreased, in an offsetting manner, as the wind velocity changes.
