if what is above is true
a small solenoid with a piston can be tasked to force "a small amount of water"
thru a reed valve into a chamber ON the hot exhaust , when that water converted to steam that could be routed to a diaphragm which would expand
with a rod to harness the movement, after the diaphragm moves up
it would expose a hole to
vent the steam, spring closes diaphragm to rest position , repeat .
if there was more energy in the diaphragm movement than needed to operate the solenoid
you would have something .
