In the "Lustron" homes of the 50's (Pre-fab all metal homes made with porcelain enameled steel) they had an interesting gizmo made by Thor that was both a dishwasher and a clothes washer. All you had to do is add or remove a rack designed to hold your dishes. I've heard it didn't work very well. Here's an excerpt from a Wikipedia link: Automagic washer/dishwasher In the 1940s, Thor introduced the Automagic hybrid washer/dishwasher. The top-loading machine included both a removable clothes washing drum and a dish-washing drum. The Automagic was widely marketed but disappeared from the marketplace soon after its introduction, as many consumers soured to the idea of washing dirty clothing and dishes in the same machine.
