What exactly is a data center by your definition? What individuals (that are entirely disconnected from corporations) need them? How many individuals have personal data centers of such a scale that they would need to produce liquid water on-site for their computing needs?
I genuinely believe you’ve described an entirely theoretical person that doesn’t reside in this universe.
Most modern buildings have at least few racks of compute/storage for services like TV/phone/internet, camera recordings, etc. Even family houses have small racks nowadays.
Ignoring this specific example, a majority of the population uses social media for leisure and online tools for work (email, banking, etc.).
A majority of interconnects between ISPs and networks are hosted in data centres too... so there wouldn't be much of an internet without them.
If you closed all data centres over night, the majority of the above would disappear and certainly would not be able to scale as large as it had without data centres... hence, a majority of people need data centres to maintain their current standard of living.
And considering how highly technical something like a modern water treatment plant can be, data centers are already a major force behind some of our potable water.
If the principle of it is sound, which I cannot verify, then by a manufacturer picking up the idea. Developing it into a product and selling it to individuals.
They are basically saying (paraphrasing) "Hey we suck at manufacturing things at scale, so we won't continue with this idea. But we don't want to let our learnings go to waste. Go ahead and learn from our experiments and mistakes. Maybe one of you out there can make it work as a product."
>The team aimed to build a highly lightweight, portable, cheap (<5% of user’s income) device that an individual could use to produce 5L of drinking water per day.
Why is it "dystopian" and "co-opting" if a company uses a technology like this to operate in a more environmentally friendly way?
People love to shit on companies (not specific ones, just "big companies" as a concept in general), completely ignoring where our standard of living comes from.
