jdgFirefly,
I missed the turbine driven belt pulley idea, that is interesting, and may work well, though turbines generally spin in the 15K+ rpm range...
I'm a little unsure of the way it would react to normal driving. There are sudden changes from lots of heat to none in the exhaust. I feel a system like this would have to much of a delay to react to this effectively. But a turbo charger acts in a similar way, before an acceleration you might warm up your boiler...

the pump could be driven by a turbine or expander, whatever is used, and by expander i mean positive displacement motor. A PD motor could be low rpm high torque.
Regarding the delay in system response, I don't think it will be a problem if its just driving the alternator.
About the pressure, I'm only thinking of a lower pressure system like 300psi and under or even below atmospheric pressure. the reason I'm thinking lower pressure is because it is safer and easier to build but also at lower pressures we will be able to remove more of the heat from the exhaust. I'm even thinking if its bellow atmospheric pressure then the engine coolant could even boil the water and maybe the exhaust could super heat the steam.
Of course a low pressure system would be bulkier, maybe to the point of impracticality.
