ISTM that using heat exchangers on the exhaust and using either air or
water/antifreeze as a working fluid would be the way to go.  Prolly have to
hang a centrifugal pump off the engine somewhere if you go the water route,
though a similar electric pump might be easier to place (lots more $$$,
though, I bet).  I think you'd need to use air (or liquid sodium maybe) as
the first stage because it doesn't want to boil when it gets to 500 degrees
or whatever.
