Obviously a Water Recovery System that enables astronauts to safely reclaim and recycle the water they typically excrete, exhale, lose in sweat evaporation or as part of the process of cooking or bathing represents a pronouncedly more cost-effective use of a extremely scarce and expensive liquid resource.
And it doesn't hurt that NASA affirms that "Water From This System (is) Cleaner Than U.S. Tap Water."
Now, we here at spacemeals.com have to ask: Are there mass applications for the Water Recovery System down here on Earth? That is, will the system become as much a part of the fabric of life on the planet as say Aluminum Foil -- another product of human space flight?
Frankly, we don't quite visualize a situation 50 years in the future in which every household on the planet is able to recover and recycle its own waste-water using this technology.
But you never know. Water Recovery Systems safely incorporated in to house-hold plumbing may become no more expensive than the average kitchen stove today; in fact, the big expense of utilizing such a system would be in the monthly fee you'd presumably pay a service to monitor the system's filtering efficiency;
We might also see closed-loop, personal water recovery systems by that time functioning as a more elegant version of Frank Herbert's Dune Still Suits, "wear" Herbert conceived of that might be able to keep a user hydrated for weeks without him/her ever actually needing to ingest additional water.
Or we might see a personal recovery system that allows some sort of intravenous delivery of water that removes the need for the drinking-process itself. Or even a system that integrates a means by which water is not only recovered from a users waste, but also simultaneously from the moisture present in the surrounding atmosphere; users of such a system might effectively never need to take on additional water by way of water fountains or consumption of bottled water, water-based drinks, container drinks or water-containing food).
It does seem more probable that in the near future we'd see water recovery systems used on Earth by military personnel dispatched to remote locations or by people living in desert or disaster-areas where water is scarce or otherwise compromised in some manner. We might also expect to see RV buyers and commercial, vehicle-based businesses install on-board water recovery systems too.
Also probable might be more "commercial," "pop-culture" applications of NASA's Water Recovery System. Consider the following scenarios:
