Another take on off grid refrigeration...

This is just a trivial curiosity.

One unusual aspect of superconductors is EVERY piece of it is at the SAME temperature.

Since cold cannot be focused with a magnifying glass, it is the hot end of a long rod of
high temperature superconductor which is collecting energy to conduct to the cold end.

If the hot end is in your fridge and the other end in at sub-zero, you have a passive cooling system.

Like I said, this is just a curiosity.

Thanks Creighton, not to worry on the pics, you gave a good enough description that I get it.
Thanks to Edward too, great comic on Bucky's discovery on cooling air in a dome in those links.

Bucky Fuller was awesome. Way, way, way ahead of his time. One of the few great minds working towards the betterment of man instead of the profit motive.

If you want a starting point for his stuff, a good book would be Bucky Works, by J. Baldwin, who was an editor/contributor to all the Whole Earth stuff and worked closely with Bucky for years.
Bucky tends to be difficult to "get" in his own writing. it's thick.

A bit more complex but good basic book on his stuff would be The Dymaxion World of Buckminster Fuller, which is in the public domain so available free in a few places.

If you prefer video, here's a Youtube search of his stuff:

Wow! wonderfully clever and  simplified ideas and recipes for food preservation with the least effort and "modern" inputs.
You could definitely eat like royalty in survival and other tough situations with this book and enough forethought to stash a few things ahead of time.

The old boy with the sailboat's trick of reheating your stew was in here, which was what made me think to post it here.

I'll go so far as to say it's a specialized equivalent of the Joy of Cooking, my very favorite cookbook. Favorite because of the explanations of why things work the way they do and very basic ingredients.

The little $2 book she has here is a good one too for figuring out just what to have laid in ahead of time. Can't find the link at the moment.
