Abstract
The sunbeam condensation equipment using a concave mirror is proposed which imitate the astronomical motion mechanically to persuade the sun constantly. A hollow shaft is directed to the polestar, and the hollow shaft is rotated one revolution per day driven by a synchronous motor. The concave mirror is attached on the gimbal mechanism which applied to the end of the hollow shaft. An inclined disk is attached at the center of the gimbal, which is driven by a shaft in the hollow shaft at the speed of one revolution per year. This inclined disk control the gimbal in order to follow the seasonal sunbeam angle change. The sunbeam is condensed and reflected to the same spot by a concave mirror. The experiment of this equipment has been achieved successfully, and the feasibility of this system is clarified.
