PROBLEM TO BE SOLVED: To provide a solar heat stirling engine power generation device capable of securing a stable power generation amount even in reduction of solar heat.SOLUTION: A power generation device utilizing solar heat and dry ice, has a cylindrical heat exchange portion having a rotary plate including a plurality of fins disposed on a peripheral surface at a specific angle to an axial direction, a heat input portion positioned at an upper half portion of the heat exchange potion to collect the solar heat, a cooling chamber accommodating a lower half portion of the heat exchange portion to receive water and dry ice, and a power generating portion having a rotor driven by the rotary plate of the heat exchange portion. The rotary plate including the fins, is rotated by movement of air caused by expansion/contraction of air at the upper portion in the heat exchange portion heated by solar heat and waste heat by power generation and the air of the lower portion in the heat exchange portion cooled by water and dry ice, and movement of the air generated in a process of expanding and discharging carbon dioxide generated by vaporization of dry ice into the heat exchange portion, and electric power is produced by rotation of the rotor of the power generating portion.SELECTED DRAWING: Figure 3 |
