I understand that this topic is titled "Exhaust Heat Recovery - Steam Power".
In one post, Daox set a modestly low performance bar for this thread:

But in a previous post, Daox had this to say about peltiers/TECs:

Curiously, the efficiency of the peltiers/TEC approach could actually exceed the low performance bar for the steam method by a considerable margin, and would appear to have none of the complexity and weight issues of steam.
So my question is why walk right past a possible solution?
