ABSTRACT:
An improved friction heater apparatus (10) comprises a thin walled metallic drum (25) sealed on both ends, having a centrally disposed axle (14) mounted therein, and a plurality of free floating friction elements (16) operatively associated with the axle (14), wherein the rotary motion of the axle will impart centrifugal force to the friction elements to radially displace the friction elements with respect to the axle, and into engagement with the wall of the metallic drum (25).
