> Scaled up, that’s 5.8 L (1.5 gal) per kilogram (2.2 lb) of material used per day, which is enough to satisfy several people’s daily water needs. No knock on the device itself but this is barely enough for two people, especially in arid conditions.

I think it's regarding daily drinking needs, and not other uses for water. The metric I am familiar with is the average person should consume 8 cups of water a day, so 1.5gal of drinkable water would support that need.

    The article doesn't say drink 11-15cups of water a day.
    - yial 2y ago
      It says 20% comes from food, (which depends on what you eat, right?) But taking it literally it would then say to drink; 12.4 cups for men. 9.2 for women.

        Despite what common belief might indicate, coffee-soda-beer etc all count. But yes, if you are self supporting you would need water to make those things at home so the problem doesn’t change much.

        I know they count. I regret not changing what the article said to fluid in my post. The point I was trying to make is that there is a required / recommended fluid intake for people each day.

        The numeric recommendation is "fluid" which includes water, food, and water included in other beverages. It may seem like splitting hairs, but the OP's comment was regarding 1.5Gal of water not being enough for a single person. Using the 8-cups of water a day, 1.5gal of water does meet that requirement.

  The 8 cups thing is pure tabloid science, like red wine is good for your hear, or getting 10k steps a day makes you more healthy. It's not actually based in facts.
  - krisoft 2y ago
    I believe here it is used as a rough estimate of the drinking water needs of a human, and as such it is fine? The problem is when people take it as an exact number they must drink every day or else…
    - hinkley 2y ago
      They also backpedaled and allowed that your first cup of coffee or tea in a day counts as one of those beverages. I think beyond that the diuretic effect cancels out some of the fluids. If your pee is clear stop drinking. That’s how I rehydrate after a workout. That’s how a lot of actually healthy people do. Over time I’m growing more fond of the habit of calling people who aim for the trappings of a discipline without following it as cosplayers or LARPers. The people carrying the quart bottle of water are LARPing.

        This seems weirdly hostile to drinking water. Some people like drinking throughout the day and/or feel better when they are well hydrated. Drinking enough water is one of the easiest healthy habits to pick up and stick with; it takes way less effort than exercising or learning to cook healthier meals. > If your pee is clear stop drinking. Why? A person has to drink a lot of water for it to be a problem, far more than someone out and about with a bottle is going to consume. More water probably won't help anything if your pee is already clear, but it won't hurt anything either and most people drink too little water as it is. Getting mad a people for carrying a water bottle around just seems weird. Depending on the area, it's not always easy to get a drink any time you want one. I guess if people are bragging about how hydrated they are it would be annoying. Bragging about how healthy your habits are is douchey in any context, but I've literally never seen someone act like that because they drink enough water.

  My family uses about 20 liters a week per person. That's for drinking and cooking.
- treflop 2y ago
  I suppose if I’m doing nothing, I’ll drink 8 cups in a day. But most days when I’m out and about, I’m drinking about a gallon. And if it’s hot, it’s more. There was a short and dumb period where I started buying plastic waste bottles and I was blowing through like 6-8 plastic bottles per day.
  - michpoch 2y ago
    > I’m drinking about a gallon. And if it’s hot, it’s more. Can I ask how tall / heavy are you? Gallon is almost 4 litres of water, I can hardly imagine anyone being able to drink more in a day, and even that sounds like a lot.
    - erikaww 2y ago
      On hot days, I’ll drink nearly two gallons. Most days 1.5 gallons. Just water. I have a very large cup that is a pint and a cup. I’ll drink 8-10 of those a day. Though I eat a lot of salty/dry foods. America baby. If I go for a long bike ride I’ll be able to wring my shirt/sweatshirt and sweat will come pouring out. After a long ride I’ll drink nearly half a gallon of water. Likely excessive but it tastes really good. It’s likely there is a very large variation in the water people need to consume. During college, I knew individuals that would drink merely a glass or two all day (minus before/after going to the library). Very small water bottles. Though these individuals looked to be <100 lbs.

      I think you’re talking to someone who is very serious about water consumption. Most people do not need a gallon a day. Not even close. While there is nothing wrong with it, we are not nearly as dehydrated a nation as the local news station seems to claim every 6 weeks or so or r/hydrohomies

      6’ 165lbs I remember drinking half of a 1 gallon plastic water jug in an hour changing a tire in the middle of a desert when it was 110°F.

  The usual recommendation around here is to consume around 3l of water per day just to stay hydrated, i.e., not for hygiene or other uses.
jjmarr 2y ago
Drinking water has to be higher quality than water used to shower or flush a toilet. In a place with only low quality water, this can be more efficient than purifying it.
Modified3019 2y ago
Yeah that’s a crazy low number for several people. I think they are confused on the difference between the amount of water needed to keep several people barely alive vs able to function without concern. When I was doing ag work in kansas during summer, I’d go through a gallon or more a day of just drinking water.
