in reply to robryk • •IMO: Too complex, too costly, one more failure point. In principle, the wet variant is for civilized environment mostly – street workers / medics and such.
The design is open, though, so one can modify it at will.

Unrelatedly, I noticed:

or antifreeze liquid.
~1/4 of that liquid is calcium. Daily recommended intake of calcium is on the order of magnitude of 1g. Random sites on the internet claim that taking more than ~3g per day is a bad idea and NHS claims that it can cause diarrhea (nhs.uk/conditions/vitamins-and…). It might be a bad idea to drink that.

What I refer to is that CaCl2 is widely used as a food add-on

The reference for it being considered generally safe in the US lists sub-1% accepted levels in various foods: accessdata.fda.gov/scripts/cdr…

in reply to robryk • •I will not.
I am not selling anything, I am not writing a scientific report and I clearly marked the statement you refer to as my opinion only, which means you are welcome to ignore it.
I spent two days thinking on this topic (most energy went towards making it as simple as possible) and the whole day today on experiments and measurments, let alone sourcing materials.
I am tired and not inclined towards pointless theoretical conversations. Get your hands dirty and show the world a better version.
