Create An Electricity-Free Refrigerator With Flower Pots And Sand

If you're hanging outside and don't want to rely on inefficient coolers to keep your drinks cold, you can make this surprisingly effective refrigerator out of a few flower pots.

For this project you'll need two terracotta pots, one larger than the other. You'll also need something to plug up the holes in the bottom, as well as some sand, water, and a cloth or towel. Basically, you need to put one pot inside the other, and fill up the spaces with wet sand, which keeps the inside of the pots cold. You'l also need to put a wet towel over the top to keep the warm air and light from getting in. It's incredibly cheap, very effective, and doesn't require any electricity.

    Well, sure, but it's not really a refridgerator, is it? It's not going to make warm things cold.

      I think it would to a point...
      The evaporation of water from the sand and clay pots would create a cooling effect.
      It's not going to be icy cold, but it'd bring the temperature down to 15 degrees or so.

      It kind of is a refrigerator though - It's just not as efficient as one using refrigerant gasses, they both are working on the same principle.

      Seems you could just chuck a wet towel over an eski though and it'd have a similar effect?

    without a doubt it works mate using the two pots, separated by a layer of sand, which is kept moist at all times. Evaporation causes the inner pot to stay notably cooler than the outside pot. With this system, vegetables such as eggplants stay fresh for 30 days, instead of the usual 3, while tomatoes and peppers last for up to 3 weeks not 2 days

    Actually this is amazing! It keeps food/drink cool without electricity by using evaporative cooling. A porous outer earthenware pot, lined with wet sand, contains an inner pot (which can be glazed to prevent penetration by the liquid) within which the food is placed. The evaporation of the outer liquid draws heat from the inner pot.

    Amazing great find!

    If you're all fired up and want to use an up-scaled version of this on a permanent basis, might I suggest adding a small amount of bleach to the water to stop mould and fungi from accumulating on the inside of the said fridge!! #}
