A couple of small flash boilers and a firebox that will burn anything combustible with a centrifugal compressor to transfer the power to a drive train. A free turbine to transfer power, as used in helicopters.
Axial compressors are more efficient but more complicated and expensive than centrifugal flow
Wood pellets, compressed paper and cardboard blocks for fuel.
The reason water is used is because it is cheap, nontoxic and the amount of expansion gained from heating water to steam is unrivaled. I don't know of a better fluid for this application.
Steam powered cars.

old school car manuals came with instructions on how to change the fluids. Nowadays they tell you not to lick the battery.
