Low Delta-T Stirling Engine

The Stirling Engine runs on the heat from a warm hand (approximately a 4° C differential from room temperature). This beautifully made engine featuring high precision components, low-friction graphite piston, ball bearings and counter-weighted cranks will amaze students. When it's not used in class, teachers can set it on the back of their computer monitor and explain thermodynamics to students who come into their office.
