How does a Drinking Bird convert thermal into mechanical energy?
« on: 10/06/2017 20:46:44 »
Drinking bird converts ambient heat into mechanical energy. It does it 24/7/365, thus basically does need energy storage.
Here is interesting patent:

Does anyone tried to build it?

Anything which provides a temp differential. I've used a sliver of ice cube taped on and no beaker of water.
