I think it would be meant for solar water heating in the house, it won't be hot enough to drive a steam turbine.

What if a liquid (e.g. acetone) with a lower boiling point (57C for acetone) is used?

small temperature gradient means low efficiency in a heat engine. See: https://en.wikipedia.org/wiki/Carnot_cycle#The_Carnot_cycle
A "35% efficient steam [system]" is not a physical reality here.
