Re: Extreme Cold
I have been doing some research on dehumidifying without electricity. I have found a few things and are going to test them out. I found a site that sells a plastic bucket with replaceable "crystals" suspended in the bucket. Sounds like the crystals absorb the water to saturation and drip into the base of the bucket, then you need to drain and replace crystals. As it turns out the crystals are calcium chloride (ice melt). Now I found other forums that talked about hanging rock salt in burlap a bag over a bucket and collecting water in the same manor as the store bought one. this is only good for 50% humidity and up. But you are looking at 100% at the envelope of the boat. What I am proposing to do is get bag and ice melter and hang high as possible and put 5 gal bucket under.
I am also pondering a glycol filled closed loop exchanger for winter humidification by convection. No power.
I'll let you know how I make out.
