Recently, the German government advised their citizens to stockpile essential items, I think they said a week's supply. I heeded that warning, asking myself why they felt the need to tell their citizens this. I have a feeling their central bank is on the brink of collapse, which will have huge financial implications.
I wanna talk about water filters.
I'm curious... let's assume the world has gone to shit and we've run out of bottled water or our regular water supply is compromised. What does mojo do?
I've been looking into water filters, how to make them. The best plan I can come up with so far is to first chlorinate the water, and then pass it through activated carbon. I'll make the activated carbon by first making charcoal, and then treating it with calcium chloride.
Is this sufficient and practical? I currently have a 1kg bag of CaCl2 on order from ebay, and I already have some water purification tablets. These will simply go into storage, and I'll likely increase these supplies over time, adding pool grade cholrine flakes which I intend to buy next week.
What I'd also like to know is how practical it is to make CaCl2, and Cl2, using nature. Let's assume we have a supply of limestone and salt.... we have calcium and chlorine in these compounds. Can they be processed safely to give us Cl2 and CaCl2? I think it's safe to say that electrolysis of molten salt is impractical and unsafe, so that one's out.
If we can't make CaCl2 and Cl2 from salt and lime, are there any other common compounds we can process?
I think this kind of knowledge is worth more than water itself in a post apocolyptic world. I've got 20l of mineral water in storage and will increase that over time, but of course that's a short term solution... effective for bunkering down for a period of time after a disaster, but not effective when it comes to sustaining life indefinitely if infrastructure is compromised.
Also, in your opinion, what would be the most valuable commodities in a collapsed world? Obviously water and water purification methods, but things like salt... it can preserve food, and has chemical properties that can perhaps be exploited. Salt is obvious though, what properties does sugar have other than sweetening?
