I suppose this is a robo function, If not I would like to see your
comments on the Moller  compound wankel, yet to enter production

The idea is not new. Rolls Royce tried something similar awhile back.
It will probably work somewhat similar to a compound steam piston engine.
The trouble is.... Moller is in the biz of selling stock and not producing hardware. He has yet to produce anything in the last 30 years except mockups and non functioning prototypes.

I suspect it does not pay off in terms of cost size or weight.

A turbine is the tried and true way to extract the excess energy in the exhaust.
