Since I'm having difficulty getting copper etc for a boiler for my Westbury-style engine, my idle hands have turned to other engines ...
I'm well aware that most places totally ban the internal-combustion engine because of the infernal noise (and potential pollution) they put out but I wondered if the following might be acceptable:-
A/ Slow-revving stationary-type, petrol engine, like the twin-flywheel, hopper-cooled ones you see at rallies ;
B/ External combustion engines e.g.
1/ Flame-licker (vacuum) engine;
2/ Stirling engine.
Of course any of them would have to be suitably geared to the paddle-wheels, I'm not sure about reversing, and speed-control could be very limited, but it would be different.
What do you think?
