But this isn't true! An external combustion engine, like
a steam engine, does NOT produce the steam, it only uses
it!  A single boiler can be used to run hundreds of steam
engines, the steam is an energy supply, no different than
air pressure to a pneumatic motor, or hydraulic pressure to
a hydraulic motor.
