#2There is a lot of energy involved in the phase change of water. We've also had dehumidifiers for over 100 years. The takeaway from that is, dehumidifiers produce don't produce water well in arid environments.

This makes me wonder if the Gates Foundation is properly utilizing scientific expertise.

But you're right. It's the company that I was most surprised to see in the list. The economics don't yet make sense to me.
I pushed Carmichael Roberts (BEV's head of investing) to explain. He said he has studied water startups for years, and he really likes the tech. But more importantly, he is very impressed by Cody's skill to sell this unit and far wide. It's already in 16 countries.

#5I wrote this article, and I'm happy to field any questions
I mean, isn't it enough for BEV to help fund a small sample of companies tackling some of the most challenging problems on earth? Probability of success in such an endeavour is already vanishingly small without adding further constraints. Aren't investments like these best directed at the companies with most promise, with the investors blind as to gender and race, with equality problems tackled elsewhere (e.g. in employment regulation etc.)?

I'm curious about why you included this sentence: 'The startups announced by BEV so far are all North American, and most of their leadership is also largely white and male' I mean, isn't it enough for BEV to help fund a small sample of companies tackling some of the most challenging problems on earth? Probability of success in such an endeavour is already vanishingly small without adding further constraints. Aren't i…
We've tried being gender and race blind. But it's not helped us much, because systemic biases can't simply be overcome that way. There are good ideas in all corners, but if you want to elevate those that don't come from privileged backgrounds you have to work harder.

So the tech inside Zero Mass Water is not the same as dehumidifier. Instead, they use a sophisticated absorbent to selectively capture water, heat it to release the water, then sterilize and add minerals. But you're right.

So it's using a dessicant? Heating a saturated dessicant in an enclosed environment can produce a hot, high humidity environment where dehumidification is easy. That said, it will still produce the most water someplace like San Francisco, where the humidity is high. There are places where humidity is high and the rainfall is very low.
Apparently, Zero Mass Water is using some good engineering to get something like a 4X efficiency increase for water extraction over existing commercial dessicant dehumidifiers. It's possible that removing the requirement to process large volumes of air could produce such an efficiency increase.
