United Scientific™ Low Temperature Difference Stirling Engine

Description

Illustrates conversion of heat energy into mechanical work using a thermodynamic cycle similar to the Carnot cycle.

• Runs by exploiting the heat flow generated by the small temperature differences between room temperature and a container of hot water or ice
• Transports heat from a warm surface to a cold one
• Larger temperature differences make the engine rotate faster
• Engine needs two pistons, a small power piston and a larger 'displacement piston' that also stores heat energy
• Model runs at about 150rpm when powered by a cup of hot water
• Direction of rotation can be changed by switching the warm and cold surfaces
• Functions 'in reverse' as a heat pump by putting in mechanical energy and creating a temperature difference
