There’s another fridge discussion at No Impact Man, where he’s asked for ideas on how to keep milk fresh. In one of the comments, someone pointed to a passive ice box that freezes about a cubic meter of ice in winter and keeps your food cool the rest of the year. Kick ass. Unfortunately it looks like it requires much colder winter temperatures than we get here in Marche.
Someone else mentioned the Mitti Cool, a passive clay refrigerator invented in India. That’s more like it!
