Abstract: A solar heated device including a conduit for expansion and flow of gases, and a solar light collector for heating the gas in the conduit, is provided with a gas turbine that is driven by the gas as it expands as a result of the solar heating. The conduit may include an inlet for introducing air, or an inlet for introducing water spray (later steam), or both, thus supplying the gas which is heated and expanded in the conduit to drive the gas turbine. The light collector is preferably a parabolic reflector that directs sunlight on the conduit in order to heat and expand the gas therein. The turbine ordinarily drives an electric generator.
