The Doble steam car was an engineering marvel, it was the most reliable steam car ever designed; I'm not surprised this thing worked with one of the Doble engineers working on it.
I wonder about the range?

I wonder what the pre take off checks are like
Hatches and HArness -secure
fuel is burning and creating enough heat
suffiencent steam for flight
Trim set
ect. ect.
would be funny at the threshold seeing the pilot with a small shovell hurrying to stock the fire.

The toon is the best part of this vid. love it

The other thing is that I'm sure you could find a good home for 250 hp. in a plane that big, and probably a whole lot more... Probably not that airframe, but that size anyway.
Or... What if you had a bigger plane with a boiler in the fuselage and wing-mounted engines? That might be something to behold, if you could make enough steam.

Well, I would think the variable-pitch prop would only be necessary if you had a turbine-driven setup, because turbines aren't efficient at low speed -- piston engines do much better there. The advantage you'd be going for with a turbine would be and increased power-to-weight ratio. I'm sure that one a plane that size, your turbine would be a pretty small unit, with a pretty substantial gear reduction to the prop.
Dealing with the weight of the boiler and firebox is what blows my mind.

Steam turbines aren't economical or practical below about 250 horsepower. But who's to say? I'm not sure a variable pitch prop would be necessary since the operating speed of a piston steam engine is very low compared to an IC engine. A big paddle prop would be best to get the most 'bite'.

To think, we look at the past for ideas, all the way to this oddity.
Steam powered glider....

Yeah me to, did you notisched they lie? It was actually a nuclear engine.

I wonder how things might have been if they'd used a steam turbine and a variable-pitch prop...
