The aim of this study is to improve the performance of a gravity propelled low temperature engine. It consists of four concentric cylindrical tanks pairs, operating with two fluids, water and 1, 1, 1, 2-tetrafluoroethane (R-134a). The inner tank holds water which is responsible for producing rotation while the annulus between the concentric cylindrical tanks holds R-134a which vaporizes and produces the vapour pressure that moves water from lower to upper tank mates. Wheel rotation is achieved when the water mass falls by gravity from this height. The inner tanks of the tank pairs are linked by a pipe through which the working fluid is transferred. The entire assembly forms a power wheel of 1.5 m diameter. Heat energy is provided by warm water at 50°C contained in a trough located at the bottom of the wheel. Test results reveal that an average wheel speed of 2.5-3.0 rpm is possible, representing a performance improvement of over 500%. This corresponds to a possible power generation of 30-35 W. Thus power generation from this engine is possible and has the potential to serve as a good alternative power source in remote locations without grid connected electricity.
