Abstract

The present invention provides novel engine technologies for power generation and work applications. The engines transform sunlight, heat, or cold, directly into mechanical force. The invention uses a focusing means to apply temperature differentials to a thermally reactive material retained in moveable housings. Said thermally reactive material is mounted in contact with a bearing element configured to apply directional force to said thermally reactive material surface as it changes shape in response to said applied temperature differentials.
