The return to steam powered transportation???? (Original Post) melm00se Dec 2021 OP
Where do you carry the condenser on locomotives or automobiles? Water acts as a lubricant? NT mahatmakanejeeves Dec 2021 #1

Steam is great if you have a lot of water nearby to act as a coolant, to condense the steam back to its liquid state. That's why all your power plants that run on steam turbines are next to lakes or rivers.

Automobile or locomotive? The water is used once and then thrown away. Hence, the tender, which carried fuel and water. The South African Railways did have a class of condensing steam locomotives, but I believe most of those got converted back to a non-condensing variety.

As for water as a lubricant, I have a hard time imaging that. On locomotives, oil was injected into the steam headed to the cylinders to act as a lubricant.

we're still burning shit to extract the energy from it.

That's the basic problem. This engine may burn "cleaner" than typical gas engines, but it's still burning shit. Burning waste engine oil is not a good solution either, you get more particulates exhausted.
