It's October , and usually the rainy season starts in the first week and it is usually rain and clouds for the whole month after that. This year, October had a few cloudy days but lots of sun too! So, finally, I popped down to the gorge with a 4 liter milk container and filled it with sea water, came back and started evaporating off the water on a frying pan on the sun scoop. (Not a clue what the technique is because I never did it before.). First day, I started late and the sun just peeped through the clouds, not much got evaporated, maybe 200 ml, next day, I wasn't paying much attention and it boiled off a few times, then I had to leave, so poured the last liter and a half on, and hoped for the best. It didn't get finished, and I covered it and let it boil off the next day. So, what did I learn. Well, don't fully dry it on the pan, I ended up with a white rock that is harder than some sandstone on the islands here. I can only imagine how much faster it will go in summer! The artesian sea salt from 4 liters of of sea water on vancouver island sells for $8.40 and I have a feeling you could make 4 or more liters worth a day in Summer. Anyway see the video. In a prepper group, I was told that the right way to do it is to filter your sea water first, boil off 3/4 of the water, then filter out the lime and gypsum that is deposited (I think with coffee filter paper) then boil it down again until there is salt in brine. Then wash off the brine (with saturated clean brine). The brine you wash off contains magnesium chloride, and potassium chloride (which are very bitter tasting) and then dry your salt gently to finish it off! So, that brine that you have washed off, I guess you can experiment with it separately. See if you can do struvite magic, by adding pee to it and extracting the magnesium phosphate to be used as fertilizer. The nice thing about the sun scoop is that it has solar tracking, so you don't have to be there all the time watching it. I would love it if someone else tried to make a sun scoop. I thought there were hundreds of thousands of DIY enthusiasts across the world, where are they?
