Gravity Propelled Low Temperature Engine

Research Journal of Applied Sciences, Engineering and Technology, 2014
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
