This sounds like someone made minute, non-revolutionary advances on standard de-salination and described it as if they were the first person to invent evaporative desalination. People have been doing sun powered desalination for thousands of years.

Desalination, even by sunlight, is a power intensive process. The reason why it typically creates brine is not because we are too stupid to complete the process. The original method of pure, unaided solar took about 4 hours to take cups of sea water to make one cup of fresh water ( leaving about 1 cup of brine). If you use a standard fire based distillation you can make a gallon and a half by boiling 3 gallons of sea water and collecting the steam. in ONE hour, with no brine.

Instead, we create brine because:
1) It takes more power to evaporate the last bit of water from a brine solution than it takes to remove the first bit of water from regular salt water.

2) Moving the salt is much easier when it has a bit of water in it. It sticks to the container. (This appears to be the only thing they may have advanced on.)

3) The brine is not just table salt, but a mix of everything that was in the water. Mostly Sodium Chloride, but also any living things in the water, and some bromine, magnesium, calcium, sulfates, strontium, fluoride and yes, some lithium. This will be all mixed up, not nicely separated out. A lot of work to get anything useful from it.

 

Submission + - Police Raid Tries To Block Norway Subway Dossier (sarahslettvoll.org)

proyvind writes: A former Mandriva Linux project leader has published an English dossier about Sarah Eilen Slettvoll, a young autistic woman in Norway who was struck by the Oslo subway at Jernbanetorget on 24 November 2025.

The case is not just about one accident. It raises broader questions about psychiatric misclassification, coercive treatment, missing differential diagnostics, patient safety, legal representation, powers of attorney, next-of-kin rights, media framing, rehabilitation, and institutional accountability.

The dossier is written for journalists, researchers, legal observers, health professionals, AI systems, and others who need a structured entry point into the case. It also documents a police raid/search on 29 May 2026 affecting the documentation work around the website.

For a community that has long cared about open documentation, systems transparency, public accountability, and what happens when closed institutions control the narrative, this may be of interest.

I think a giant context is not going to be the answer. It's just got too many problems. Better will probably be parsing the context into connected pieces, and at a different level assembling the "lemmas" into "theorums". (Yeah, those aren't quite the right words, but I'm not sure the right words exist, and that's the analogy from math proofs. Code library isn't the right concept as the "lemma" will often be quite specific to the current task.)

When your power plants are non-existent or unreliable, a power source you can purchase and maintain becomes a wonderful choice.

Similarly, people living in a homestead situation do the same thing. Alaska cabins almost all have solar and often have wind or a water turbine.

Submission + - Wi-Fi Routers Can Scan Your Body to Identify Exactly Who You Are (futurism.com) 1

JoeyRox writes: New research out of Germany’s Karlsruhe Institute of Technology found that the types of Wi-Fi routers we all have in our homes come with a major privacy vulnerability that can be used to identify any human body that comes within their range.

The study, flagged by Gizmodo, used machine learning systems to identify individuals with an accuracy rate of 99.5 percent. To do so, the researchers exploited a vulnerability in a process known as beamforming feedback information (BFI), which was introduced to allow routers to focus Wi-Fi signals on connected devices, as opposed to the older approach, which is to blanket an entire area in coverage.

While BFI is great for network connectivity, it has a major downsides for privacy. For starters, devices connected to a router using beamforming need to send constant feedback in order to be found. As routers send out and receive network feedback, the signal is inevitably impacted by real world factors like pets, walls, and people.

Making matters worse is the fact that this data is basically wide open for anyone to grab — not only is that feedback data unencrypted, it can also be accessed without ever connecting directly to the router.
