Low-energy food storage

Food cooling without electricity starts with clay, water, and shade.

If you are looking for a simple way to explore food cooling without electricity, a zeer pot is one of the clearest experiments to build and understand.

Not a fridge, but a useful cooler

A zeer pot is best understood as an evaporative cooler. It can help demonstrate how food storage can be supported by passive cooling, especially when used in the shade with airflow.

Good for learning and resilience

The value is partly practical and partly educational: it shows how material choice, water, air movement, and heat transfer all come together in a simple object.

What you add

The kit includes the matching terracotta pots, lid, and guide. You add sand and water so the build stays easy to ship and simple to assemble at home.

Next step

Try passive cooling at home.

Start with a complete kit, then add sand and water to bring the cooling chamber to life.
