I assumed the engineer would advise on the problems with a preesure vessel explosion
and suitable relief valves
hence the windmills , nothing wrong with a good windmill ;-)

I forgot to add solar furnaces, tracking and non tracking, also good for heating water for steam

once you have a suitable safe pressure vessel you can graduate from piston steam
to steam turbine chuff-chuff-chuff
most (70% ??)  of OZ electrical power comes from steam driven generators
nothing nancy or old hat about them

all good practical fluid mechanics, machining, fitting and turning, plumbing and thermodynamics

then you can use them to drive a permanent magnet generator ;-)
