Coca Cola Can Engine

“This is a Sterling engine, 100+ byears old technology. It works from heat-differential gas expansion between the fire source and the colder side of the piston in free air. The cola cools that part thus increasing the differential in heat, and even keeps the motor going when the fire is removed, because there´╗┐ is still a differential between the coke-cooled end and the non-cooled end. Note that this is a very weak engine only suitable for stationary low-power usage.” — CalyptratusTZM
