Off-Grid Refrigeration

I definitely think a larger pot would be better, but this video is a great introduction to the power of evaporative cooling. It might just save your meat supply in a power outage. Worth some experimentation.

Nice ... probably more of scientific interest in FL (except for the coastal areas) but folks in AZ and TX should be all over this... like building houses this way :) I wonder if you could use sea water for that? Graywater will do just fine, I'm sure...

Had a few things to say about previous posts but didn't have he time, sorry :)

I noticed Agritunity will have a workshop on permaculture ... wow ... :) Are you teaching it by any chance? :) I bet there is limited number of master gardeners in FL able to even pronounce this word and I already asked 2 of them and it's not them :)

I agree... humidity is a big problem here. We're probably better off drying and fermenting than attempting to refrigerate off grid.

And no - the class isn't mine. Maybe one of these days. Heh.

That would be good :)

I'm very impressed with Sumter extension office generally - I think they're one of the most up-to date in the state. And Agritunity is so much more progressive than the Orlando conference (and 1/10 of the price)... amazing.

I remember several "producer" types storming out of the room when Joel Salatin's son was speaking there a few years ago (back when the name was a cuss word among serious cattlemen) - priceless ...

Speaking of biochar - interesting -

Now *that* I would have paid good money to see.

I wonder if it would get cooler if you use alcohol instead of water?

It probably would - but I think alcohol would be too valuable to waste in a low-tech system like this.
