Is that your hand attempting to balance that wrist watch engine crank?
All this design stuff is all very well but what about this TS3 well known engine failure problem?
It needs sorting before going further into these futuristic designs of yours.
Swop your drumsticks for a torque wrench springs to mind.
The answer is all in the clues given?

Turbo chargers are so efficient now that at high load there is plenty of spare energy in the exhaust gas that can be recovered in a power turbine and again used to either generate electricity or mechanically fed back into the engine output shaft.
There is also the thermo electric effect that can generate electric power across large temperature differences.
The Stirling Engine is a way to recover low grade heat, where the temperature differences are less, I understand that they can work with as little as 0.5 C temperature difference between the Hot and Cold side, and you could recover the remaining waste heat from the exhaust Gas, cooling water and Lube oil with them, and again use the power to feed into the main engine shaft or to generate electricity.
Waste heat can also be used for heating purposes. Almost no energy needs to be wasted, so long as it is cost effective to recover it.
