Vehicle Air Conditioning - Economical Approach 971813

A vehicle consumes 15% extra fuel when airconditioning is switched ‘ON’. This extra consumption is due running of engine driven compressor. To overcome this extra fuel consumption and emission of additional exhaust gas to atmosphere, we need to device a system without this engine driven compressor. My paper provides approach towards making use of engine exhaust gas being wastefully discharged to atmosphere. The velocity at which the gas leaves can provide Kinetic energy and its high temperature can be put to the use as Heat energy.
