WASTE FERMENTATION HEAT POWER GENERATION METHOD AND WASTE FERMENTATION HEAT POWER GENERATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a waste fermentation heat power generation method and a waste fermentation heat power generation system which reduce a load to an environment while improving the generation efficiency.SOLUTION: A waste fermentation heat power generation system 1 includes: a shape memory material engine 11 having a high temperature side rotor 12, a low temperature side rotor 13, and an annular member 14; and power generation means 15 driven by rotary motion of the high temperature side rotor 12. The high temperature side rotor 12 and the low temperature side rotor 13 are rotated by a tensile force generated by physical property changes occurring as a temperature rises in a portion of the annular member 14, which contacts with the high temperature side rotor 12. The waste fermentation heat power generation system 1 is formed so that kinetic energy of the rotary motion in the high temperature side rotor 12 and the low temperature side rotor 13 is converted into electric energy by power generation means 15.
