I know you are joking, but for people that don’t know: Solar Stills are total scams. They might work in a pinch as a survival tool, but for long term it’s a non starter.

They have many issues, for example in places that don’t have a lot of water and thus would be the most needed, they simply don’t work. If there isn’t a lot of water in the air, there isn’t any to extract. Even in perfect conditions these things produce very little water, in most conditions you’d be lucky to get a couple of drops. Second issue is the water isn’t clean, there is so much stuff floating in the air, you can’t drink the water that comes out without filtering / boiling first. If that step is required you might as well go with ground or surface water sources. And if there isn’t any ground or surface water sources, there won’t be any water in the air most likely. Third issue is you are creating a hot and humid environment, which is an excellent breeding ground for all sorts of nasties. Think legionnaires disease and all sort of other bacteria and fungi. Within days it becomes a serious health hazard. Last issue is the materials used are almost by definition cheap and exposed to hard uv a lot of the time. This makes them degrade quickly and fall apart. Leaving plastic waste and chemicals leaking into the water it produces, until it just falls apart.

There have been so many crowd funding campaigns for clean water from the air over the past decades. Maybe some of them are simply naive and well meaning, but almost all are plain old scams. Feeding off the desire of people to help other people, only to fill their own pockets.

And furthermore, the problem with access to clean water is capitalism. There is plenty of water available, we have the means to extract it from the ground, surface and sea. We can process it, clean it, recycle it. Use trucks or pipes to transport it to places that don’t have it. The only issue is, that costs money and the people living where the water is needed don’t have a lot of money. So bringing water to these places simply doesn’t generate a profit and thus doesn’t get done. It isn’t some kind of huge technical issue, there are many rich places in the desert that have plenty of water. Think oil states in the Middle East, or places in the US like Nevada, Arizona, New Mexico etc. Capitalism is the issue, not technology.

World News

Create post

A community for discussing events around the World

Rules:

  • Rule 1: posts have the following requirements:

    • Post news articles only
    • Video links are NOT articles and will be removed.
    • Title must match the article headline
    • Not United States Internal News
    • Recent (Past 30 Days)
    • Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
  • Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think “Is this fair use?”, it probably isn’t. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.

  • Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.

  • Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.

  • Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19

  • Rule 5: Keep it civil. It’s OK to say the subject of an article is behaving like a (pejorative, pejorative). It’s NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to “Mom! He’s bugging me!” and “I’m not touching you!” Going forward, slapfights will result in removed comments and temp bans to cool off.

  • Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.

  • Rule 7: We didn’t USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you’re posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.
