Refrigerator Alternative

This is so great! I want one of these! It's a cooler made entirely of clay, designed to be an alternative to electrical refrigerators. This cooler uses no electricity, and it keeps foods cool with water. My mom was telling me that cool boxes were common before ice boxes and then refrigerators became available. I'm beginning to think that maybe I can get along just fine without a refrigerator, especially since I don't eat meat, dairy or eggs, and therefore don't need to store those more perishable foods.
