This beautiful and economical low temperature differential engine is sure to attract attention! Attractive plated steel construction gives this engine a handsome appearance.
Simply place it on a hot or cold surface (like a warm mug of coffee or water), wait for a few minutes while the heat is absorbed into the base plate, and then give the engine a gentle spin.
Watch the engine perpetually turn, speeding up as more of the heat is absorbed through the base plate. Alternatively, the base can be cooled to make the engine spin in the opposite direction.
The small footprint of this engine makes it ideal for situations where space is limited.
