Abstract: This study is about rubber heat engines which have rubbery solid as the "Working fluid". The rubber heat engines of three types were built and were studied on rotating behavior (relation between the number of revolutions and the number of rubber sporks; effect of heat source; relation between the number of revolutions and torque, power, and work; thermal efficiency). The rubber heat engines built are a) one which holds the crank fixed and rotates the rim, b) one which holds the rim fixed and rotates the crank, c) one which has vertical wheels rotated by eccentricity. The conclusions of this study are as follows; a) the potential use of rubbers as the "Working fluid" was confirmed. b) Sunlight is possible as heat source for rubber heat engines. c) Since small temperature differnces are available for heat engines, the engines can use low-grade and waste heat as the heat source.
