Abstract
An endless drive belt made of shape memory material is entrained about spd pulleys, one of which projects into a thermal heating region within which the drive belt undergoes contraction to form corrugations therein through which variable spaced contact is established with said one of the pulleys to induce rotation thereof and movement of the belt. The belt expands as it moves out of the thermal heating region causing the corrugations to flatten out as the belt approaches the other pulley.
