The design survived to be used in the Ling Tempco dishwashers and you are right, it would be far more effective at covering an 18 X 24 inch tank. The filter holes in the tube surrounding the twisted blade that threw the water were not that fine so maybe some alternate would need to be found. It might be possible to convert the water distribution pattern to spray jets on a wash arm from a recirculating pump & filter system with a water-powered motor to turn the wash arm back and forth similar to the back and forth lawn sprinklers. The steam generator that fogged the load essentially gave the last part of the rinse the properties of distilled water so rinse agent might not be needed.
