I don't have much on them, one is "Richard Clem’s Motor." Listed in Patric Kelly's document. With a note that soon after his first working car with the engine, he was killed.
Similarly to the video, you are using a vortex to separate out two forces. In this case, you are separating out equal and opposite kinetic forces, turning one into heat, so that you can use the other for useful work.
There is another contical vortex I've been exposed to concerning heating, but I do not remember the name, so I am not able to easily find it.
Cooking oil vortex.
