This one is mostly for people who live in rainy places. I live in a place that gets plenty of rain for about 6 months of the year. Most houses have downspouts, to carry the rainwater away. Some people store a bit of this water in barrels or other vessels, but most of it is directed toward the garden, treed areas or to the city sewers.
Downspouts are the most common method of getting water from the roof to the ground. I prefer chains that exit the upper gutters and allow the water to flow smoothly down without splashing all over the walls. This is common in Japanese houses. See photo below.
A simple basket can be fashioned for hanging from one of these chains , just as bird feeders and chimes can be hung from a chain.
We have a supply of clean water that is already in motion. It tends to cling to the chain so it might be necessary to clip a few thin bits of metal to the chain as a diffuser. This will splash the water in all directions so that every part of the dishes get cleaned. A small boat propeller could be mounted above the dish rack so that the water spins it. This would ensure that water is splashed in all directions.
Water only moves down with this system , so cups must be placed so that they catch water. Electric dishwashers spread water in all directions.
There is no need to heat or cool the water. No soap is used. This may not make all dishes perfectly clean, but it will make most of them very clean. It's a long, slow rinse that can use hundreds of gallons of water.
This involves a trip outside. For me it's less than a 15 foot walk to a suitable spot for me to attach a chain. I like going outside, so this aspect is not a negative.
I imagine utilizing the existing racks from an old dishwasher. These are available for free, every day of the week. Four lengths of stainless steel chain or cable go from the corners of the dish rack to a central hook point , that is attached to the gutter chain.
Properly built houses have substantial overhangs. A large nail protruding from the siding at this point would allow a good spot for dishes to air dry. Water must be dumped out of cups before they're set to dry. Any dishes that are still greasy , should be taken into the house for a wash.
This one is so dead simple that photographs probably aren't necessary. Still I will provide some the next time I get a house to demolish during a rainy spell. Many of these houses also have a dead dishwasher. One stop shopping.
Coming soon - - - The Gutter Chain Washing Machine . It's basically the same idea but with a series of hooks attached to the chain. Clothing is hung on the hooks and water flows over them. Dead simple. I have done this in my stream, but during heavy rain, the flow can be tremendous. Some pants had to be retrieved from the valley below. I've also done this with a small cedar tree. I cut the top off and cut off all the branches leaving 6 inch stubs. Dirty work clothes were hung on those stubs and left out in the rain. I returned to the farm during a dry day to find my clothes nice and clean.
