Abstracts: Waste heat is that heat which is generated in a process by way of fuel combustion or chemical reaction, and then dumped into the environment even though it could still be reused for some useful and economic purpose. There exist today worldwide concerns about the best ways of using the deployable sources of energy, and of developing techniques to reduce pollution. This interest has encouraged research and development for re-use of the usually wasted forms of energy. There are many methods through which waste heat energy can be recovered and utilized. Stirling engines are mechanical devices working theoretically on the Stirling cycle. It uses air, hydrogen, helium, nitrogen or even vapors as working fluids. The Stirling engine offers possibility for having high efficiency engine with less exhaust emissions in comparison with the internal combustion engine. We had designed & manufactured a gamma type sterling engine which operates at high temperature difference. Our ultimate aim is to develop Low Temperature Difference (LTD) Stirling engine and for that modification in existing design is going on. In a nutshell, the aims of this project include the following: •Research on working principle of Stirling engines •Design of a Stirling engine that could be easily fabricated for small scale subsistence use •Fabrication of a prototype Stirling engine and assess its performance
