> dystopian 'how can it be co-opted by corporations for business ends' Why is it "dystopian" and "co-opting" if a company uses a technology like this to operate in a more environmentally friendly way? People love to shit on companies (not specific ones, just "big companies" as a concept in general), completely ignoring where our standard of living comes from.

Considering the project is self-described as a way to get drinking water into peoples hands, it certainly seems a bit dystopian to immediately jump to using this to collect water for DC’s… especially considering the original comment was asking “how do you build this”, not “what could you use this for”

I'd understand this more if the two uses would somehow conflict, e.g. by competing for a limited resource. But here? If anything, this is going to either preserve other water sources for others, or put more money behind the technology.

So what is the practical use of this? Let's say that I'm not an engineer or a researcher or a coder, but would like to set some of these units up to collect water. How do I do so? Do I approach someone to build this for me (who?)? How much can I expect it to cost? In other words, how can I actualize this vision: > So the H2E team asked: “What if you could put the power to generate daily drinking water into the hands…

The prototype described is tricky. Basically because they want low unit cost, they had to assume mass manufacture techniques such as vacuum forming. This means that the cost of small builds will be quite high (since there's a lot of jigging and molds that have to be 3d printed/CNC'd). Unfortunately, they don't have a BOM cost listed anywhere I've been able to find. But also because this is a prototype, and they wante…

There is already a similar device on the market called a dehumidifier. It takes a fair amount of electricity and costs over $150. I think the core of the problem may be the amount of energy it takes to harvest water vapor, especially in arid conditions. (Likely the areas where the need is greatest.)

They way I misconstrued it was to assume that the door was wide open for a a fitting joke. :-)

Such a lowbrow cheap joke to assume that open source means "come take all my stuff" vs "i've made this to share with everyone" which does a disservice to open source more than it is funny.

$150 cost and free cad files? for the needed? What a joke. It reminds me of the Americans spending thousands to develop a pen for Nasa in space. Some people took a pencil to space. Here is a project from 2015 already invented without the need of cad files and uses only local materials: https://www.warkawater.org/

Pencils are dangerous in space—they can cause fires. Also, the “space pens” were not developed with taxpayer money but instead by a private company, and they actually saved NASA a lot as they bought them for dollars instead of hundreds or thousands as they did with pencils.

Then you probably don't have humidity either, so the collector won't work.

There are many places that have fog, but no or little rain - the skeleton coast inwards/Namib desert in Namibia for example.

There's a very interesting beetle there...
