Is there a guide for DIY steam engines?
Boil water in a closed system that uses steam to move a paddle on the inside that is on the same shaft as a wheel on the outside. That's the basics. Everything else is just variations on the theme. The higher the pressure the faster it goes and more torque you get.
I guess I forgot to mention that once the steam moves the paddle the steam needs a place to cook down and go back into the boiler.
Nah, for a first step implementation in stationary applications, you can have a steam machine run an open circuit. Steam expands, performs work, exits through a valve. Just keep the water tank filled. Less efficient, but it would work. The return loop is an optimization for the next stage :)
For better efficiency the steam should be used twice, in a high pressure circuit first and on its way back to the boiler through a low pressure circuit.
I like my steam very well cooked. I let It cook down for a couple of hours.
You don't find that it starts to taste like cardboard?
Pop Pop boats are really simple steam engine systems.
