The more things change, the more things seem the same…
Back in the late 1970’s and early 1980’s, we were bringing to market a pretty revolutionary device. It would be the size of a large toaster oven, and dispense purified (as in no dissolved solids and no microbes) water for drinking for the home. This was also before folks filled up canteens full of drinking water to take with them. Our goal was to satisfy the drinking needs of up to 6 folks in a home. (We had a larger unit that would let folks fill up great reservoirs and for larger families.)
