So basically they’ve used fancy chemistry to make a better dehumidifier. “Dry air” is still around 20% humidity according to their website.

Overall, there’s just not a lot of moisture in the air for these types of systems to squeeze out. I’d be interested to see a cost/benefit analysis compared to just delivering water from somewhere else in an emergency.

“Headscale is an open source, self-hosted implementation of the Tailscale control server.”

From the article, they are converting the granular activated carbon (GAC) that holds the PFAS into graphene. The PFAS itself is just converted “into inert, nontoxic fluoride salts.”

GAC is one way to filter PFAS out of drinking water, but then you’re left with a bunch of PFAS-laden media that you have to do something with. So this is one potential method of dealing with that.
