It's like how a tomato is actually a fruit: That might be true, but it doesn't mean I'm gonna start using them for smoothies.

And then we discovered that Jox has been drinking ketchup smoothies for years.

(more soberingly, that reminds me of my grandma's tales of eating ketchup soup during the Depression).

Now that is something I can get excited about. Whenever I'm punking around in the desert I'm always thinking things like "this soil and terrain would be perfect for a vinyard if there were any fucking WATER." And then I spend an afternoon trying to daydream up a way of mass producing and scaling up the carapace of the namib desert beetle or something. Granted, there's more life in the desert than I think people really appreciate, but so much of what we think of as wasteland could be made a paradise if something like this gadget actually works and can be cheaply manufactured. Hell, maybe I can revive that dream of starting some kind of nerd commune out in the wastes. Let's be a pack of overeducated hipster Fremen. Drinks are on me.

This is nonsense. To get water out of the air, there has to be water in the air. If there's enough water in the air to get a meaningful amount out, there's probably some on the ground, and getting it out of the air is pointless. Anywhere you could do it you probably don't need to and anywhere you can't it probably would be great if you could, but you can't. It doesn't matter how good you are at getting water out of their air if it straight up isn't there. Particularly this idea of just passively sitting there and doing it. How do you cycle enough air to get anything?

I am also extremely suspicious of their numbers, that much water that fast with no energy source?

And if you think "But MIT", some of those assholes thought the hyperloop could work, so I'm still leery.

The article says the energy source is the sun, or any other source of heat.

Either my poking around for math and whatnot about relative humidity is giving me some questionable results, though. The Mojave right now appears to be 60 degrees with 30% relative humidity. I think that means you'll need to process about 260.416 cubic meters of air to get one liter of water? Relative humidity is how much water is in the air compared to the maximum amount the air can hold at that temperature before it precipitates, This page puts that at 12.8 grams per cubic meter at 15 centigrade, 30% of which is 3.84 grams per cubic meter, which means 260.416 to break a liter.

The article appears to claim a liter every 3 or 4 hours in MIT weather, which is similar - 58 F and 26% right now. Assuming it works as advertised, that's just got to be a lot of air to be running through it. How much wind are they assuming, and how big is this box?

Neat if true though.
のほも is such a good word?? the concept is kind of hard to fully get across in translation, but basically it means a feeling of pure, deep, platonic affection, and i think thats beautiful
