The fuel coming from?

I think Colin has the idea! Use one of the WWII British steam radios
that were used in the south-west Pacific. They were 'powered' by the
camp fire.

Am I correct in thinking that the sets intended to be 'crank powered'
used mostly direct heated [battery] tubes and those fast heating
direct power tubes that looked like a metal 6L6? One would think that
the design would minimize the waste power, simply because of the
limited output of the [human] power source.
