Project Name : Vapour Tor Q – phase change energy converter
Theme Name : Energy Resource & Conservation
Our prototype is principally a heat engine which uses the principal of vaporization and vapour pressure to convert low grade (low temperature different from the ambient) thermal energy into mechanical torque. The model uses heat from a reservoir (hot water tank or hot air
stream) to transfer a fluid with a low boiling point (Di chlorine thane in our device) between a balanced network of pipes and reservoirs. It causes a shift in the centre of gravity of the system, making the device move rotationally. Changing the working fluid allows the device to
be used at any temperature range.
The heat required can be provided from waste, Industrial heat sources such as engine cooling systems (radiators), hot air exhausts such as those used in cooling systems for electronic equipment etc. AC hot air exhaust and in some areas cheap solar thermal water heaters. The
device has one moving part and will be cheap to manufacture and install as required the devices to be scaled up a diameter of about 20-30 feet and the resultant torque could power flour mills, agricultural equipment, band saws and other machines without inefficient speed
converting mechanism. AC generator could also be powered by this machine wherever required.
