Steven M. Johnson imagined the shower of the future 25 years ago
We recently posted The shower of the future recycles its own water and heat, after which Steven M. Johnson sent us a note:
This was a recycling shower that I imagined would be used at a future time, though I was not in a position to imagine complex filtering, etc. My wife thought the idea was GROSS, showering fully or partially in your own dirty shower water. But at least I had a small filter on the shower head.
But it wasn't such a bad idea at all; it just needed a better filter.
