About 15 years ago (ooops, sorry getting old) I saw a programme on BBC regarding so-called free energy generators.
Before everyone goes cock-a-hoop, I am well aware this is not possible. However one 'invention' involved a steam generator which appeared to use resonance to create steam. Involved a disc of metal with suitably spaced holes, rotating in a casing driven by a motor. It was allegedly used to create hot water for showers in a local fire station (USA). Can't find anything via The God of Google.
My application is not looking for free energy (my cats have an abundant supply, usually about 4am each morning...
). However the rotary-to-heat aspect may have a function that fits my application.
I steal my nerves for the ubiquitous guffaws, but so sleeps the beast....
