Abstract
Cylindrical interior and exterior drums, each drum has a cylindrical side wall with primary and secondary end caps. Fixed primary and secondary supports are provided. Each support has a primary shaft with an interior end fixedly supported by a primary end cap of an interior drum and an exterior end rotatably supported in a support plate. A drive disc is secured to the primary shaft for rotation therewith. The drive disc has an angled exterior surface. The primary end cap of the exterior drum has an angled interior surface. A plurality of cones are in contact with the interior and exterior surfaces whereby rotation of the drive disc and the primary shaft and the interior drum will translate into counter rotation of the exterior drum. A quantity of fluid is located between the drums for generating heat in response to the counter rotation of the drums.
