no small rankine turbines or steam engines are that efficient. Best bet would be a stirling engine from qnergy http://www.qnergy.com/. About 3kW output and 30-35% efficient and designed to feed into the grid. If run in some un-prepared location like a lecture hall or foyer that would make a truly powerful demonstrator to the world.
