Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

   I got curious and found a record from the 1994 edition of the Guiness book of records of what was stated as the largest stationary steam engine, a pumping engine made in 1849 to pump water out of flooded land in Holland. No information on the flywheel was given, but the diameter of the piston was 12 feet! That one must have had one whopping big flywheel also.
