I still think it’s a pipedream. The energy needed vs what you get in return doesn’t add up for me.

I would imagin they are similar to molecular sieves. They are very porous and that’s how they trap the water. If it was easy to get out then it wouldnt trap water very well. To pull that water back out you have to really heat it up to force it to find its way out like a maze. If you where to say used black plastic, I have doubts you could get anywhere near boiling so it might be free an easy you wouldn’t be putting enough energy in to get enough water out. So you would need an external power source. No matter where (magic solar panels).

If your going to use an external power source might as well use it to put a pump on a pipe and I would guess move an infinite more amount of water for the power used.

While trucking water would be expensive. I would imagen these would be even more so. You have to buy them move them set them up and im sure do some sort of maintains. And if you want a long term solution look no further than Las Vegas. Where a big pipe is cheap and easy, well compared to what I would imaging what this would cost at the same scale.

Also to my understanding many places do have some form of water but its not safe to drink. I would rather spend the money on a filter/ purification system of water than try to pull it out of the air that would still probably need to be filtered, dust is crazy.

Now from this it sounds like a fancy dew collector with extra steps.

Why most certainly there is some niche uses for it and every situation is different. I highly doubt it has a real would massive scale use and when people promise the world( like pulling drinking water out of air) I think they are nothing more than a pipedream.

I stand by a post I made here elsewhere. It would be cheeper to load up a truck with water and move it to where you need it, or better yet build a pipeline. MOF while, like I have their uses, we already have very efficient ways yo clean and move water and no supper SciFi techno babal will replace what we already use. It the same thing as data centers in space.

MOF’s sound like normal dehumidifier with extra steps. The way I see it and from what I understand from reading this.

Put MOF outside so it absorbs water from air.

Heat MOF up to boiling( 100C) to get the water out. ( as something lime squeezing it would probably destroy it, though would be cool)

Cool the water vapor back down using normal dehumidifier means.

Why spend the energy to heat the MOF up. Just cool the air down using normal dehumidifier means. It take a ton of energy to heat water up. Edit: and cool it down but why not skip the heat up part.

It would be cheeper and easier and less energy intensive to load a truck up with water and drive it to where you need it.

How many times do we have to fall for this garbage. Well I guess if your doing it to scam dumb rich people be my guest, but this shit is dumb.
