Lived without electricity or plumbing for a number of years, and used this very system. It works remarkably well.
One unremarked advantage of being vegan, or at least a non-dairy vegetarian, is that you don't need a refrigerator. Or even this clever pot thingy.
My own (outrageously unpopular) opinion is that fridges are redundant technological bloat, invented to serve 20th-century America's meat-'n-dairy-loaded diet. I've lived without one for years, including in the tropics.
Doesn't it provide a safe way of preserving food that housing built before personal refrigeration became common won't have (a larder, basement, or even shaded garden)?
Methods of refrigeration become especially important if you do not have a regular way of retrieving food.
Not to mention, even cooked vegan food can and will spoil quicker without refrigeration.
Sure, the invention is great, not disagreeing with that.
Just saying that refrigeration is non-negotiable for meat and dairy, whereas that is not true for almost all non-animal products.
Does any big clay pot work or is it a special kind of clay/clay pot they're using?
the outer pot must be unglazed to allow it to become saturated with water. There's quite a few guides on how to make these, like this one, which detail their capabilities and the materials needed.
