Hackaday is a bit lax in their presentation: Feymans original ratchet ( or any machine like it ) cannot extract work as soon as it’s in thermal equilibrium with its surroundings.
The “surrounding chaos” mentioned is not thermal motion, rather the machine presented in the article extracts work from non equilibrium wave patterns.
