day 258  : :  blog post 012

Long-overdue, this little update is a compilation of clips I’ve shot over time bringing us to nearly current-day. I’ve been side-tracked for the last 3 weeks acquiring and setting up a second semi-trailer for us to live in which might merit a short video soon, but I hope that all future clips will be build updates as we start getting into the meat of this build. This video covers some exciting changes so, enjoy!

Drinking water from thin air

water billboard

If you haven’t seen something like this before, the unit inside this billboard uses reverse osmosis to draw moisture out of the air so that it can be stored and then used as drinking water. What isn’t entirely clear is whether pollution gets stored in the humidity and molecules in the air and then is transferred to the drinking water. I suppose a simple filter once the water has been captured could help with that.

I’ve seen this system in action and they work great. I wonder if aid organisations like WaterAid use systems like this. It seems to me like a system that should be in every community that is struggling to find clean drinking water. Here is the story about this billboard:
