The minto wheel is a power-producing device activated by evaporating and condensing a work substance. The only energy input would be from a waste heat or solar source. Write a paper explaining the operating principles of device. Indicate wether the minto wheel operates as a thermodynamic power cycle, and if so give the range of thermal efficiencies that might be achieved. Evaluate propane as a working substance and suggest an alternative. How would the wheel diameter and the volumes of the containers holding the working substance affect performance? Are there any practical applications for such a device? Discuss?
