The Amazing Drinking Bird Energy Foundations for High School …
The drinking bird is a heat engine that exploits a temperature difference to convert heat energy to a pressure difference within the device, and performs mechanical work. Like all heat engines, the drinking bird works through a thermodynamic cycle. The initial state of the system is a bird with a wet head oriented vertically. The process operates as follows: Sometimes the drinking bird is called a perpetual motion machine, but there is no such thing as perpetual motion, which would violate the laws of thermodynamics. The bird only works as long as water is evaporating from its beak, producing an energy change in the system.
