Problem is that the thermoelectric diodes aren't all that efficient. Not a problem for a nuclear-powered space probe, of course. Another and more efficient way of reclaiming exhaust energy I've seen is to let it spin a turbine (like a turbocharger), but have a generator in place of the intake side. Called a "TIGER", IIRC.
