The top-hatted “drinking bird,” once a fixture in science classrooms for demonstrating the basics of thermodynamics, is making a surprising comeback — as the inspiration for a new clean-energy ...

Inspired by the classic drinking bird toy, scientists in Hong Kong and Guangzhou, China have developed an engine that efficiently converts energy from water evaporation into electricity to power small ...

The drinking bird is an iconic desk toy, right up there with Newton's Cradle, but can you explain how it works? The principle is unintuitive at first glance, but beautifully simple in hindsight, like ...

How a “drinking bird” engine converts evaporation energy into kinetic motion. How to use a triboelectric nanogenerator to convert kinetic motion into electricity. How to generate over 100 V through ...

The action of the “Drinking Bird” is stopped when it is covered with a large bell jar. It resumes its motion when the bell jar is removed. The demonstration can be used to illustrate the expansion or ...
