Abstract:
A Thermal Differential Rotary Engine apparatus comprising, in combination:at least one circular collar means; at least one axle means located at the center of, and mounted substantially perpendicular to said circular collar means; at least one thermally reactive material strip at a fixed distance from said axle means, and fixedly mounted to said circular collar means; at least one first bearing means mounted to allow rotation of said axle means in an axis parallel to said thermally reactive material strip; at least one temperature differential focusing means configured to apply temperature differentials relative to ambient air temperatures, to said thermally reactive material retained in said circular collar means; at least one second bearing means mounted in contact with said thermally reactive material so as to apply a restrictive sliding force to said thermally reactive material surface when said surface changes shape in response to temperature differentials applied by said temperature differential focusing means, such that said circular collar means in concert with said axle means, may rotate within said first bearing means in reaction to a resultant directional force.
