@bobo:
It's probably reasonable to ask how much technology is really needed to clean clothes given a certain amount of water.
What does it take to clean a good-sized load of laundry using 40 or so gallons of water? That question was answered about 60 years ago.
What does it take to clean a good-sized load of laundry using 15 gallons of water? A more complex and expensive machine than is needed to use 40 gallons.
What does it take to clean a good-sized load of laundry using 5 gallons of water? Who says we should only use 5 gallons of water?
People in Arizona and Nevada probably don't buy as many dehumidifiers as people in Iowa. People in Arizona and Nevada can use swamp coolers in the summer, but those don't work work in Iowa where the dewpoint is 65-70F.
Maybe we should have a variety of laundry machines available that people can select from based upon regional conditions of water availability and cost.
