“Air Conditioner (A.C)” is the essential part of our lifestyle. Starting from our house to the sophisticated office and factory almost all establishments are centralized Air Conditioned .

A.C is one of the most electricity consuming machines. It increases the need of electricity generation , thereby causing more and more pollution. To overcome this limitation of the conventional A.C ,we are presenting an A.C which will generate its own electricity and will not require any external power supply.

Here we modify the sterling engine by using the condenser and evaporator of the A.C as hot and cold parts of the sterling engine. With the use of the principal of energy conservation we convert the temperature difference in between hot and cold part of the engine into the mechanical energy and generate electricity.
