A pot-in-pot refrigerator, clay pot cooler [1] or zeer (Arabic: زير) is an evaporative cooling refrigeration device which does not use electricity. It uses a porous outer clay pot (lined with wet sand) containing an inner pot (which can be glazed to prevent penetration by the liquid) within which the food is placed. The evaporation of the ...
The air supplied by the evaporative cooler is generally 80–90% relative humidity and can cause interior humidity levels as high as 65%; very humid air reduces the evaporation rate of moisture from the skin, nose, lungs, and eyes. High humidity in air accelerates corrosion, particularly in the presence of dust. This can considerably reduce the ...
The only parts which are referenced refer to the pot-in-pot refrigerator, specifically Emily Cummins's eco-fridge variant, and multiple sources refer to this as a "solar-powered refrigerator". Chris Cunningham (user:thumperward) 07:58, 6 February 2012 (UTC) Absolutely. Yes, pot in pot is solar powered, just like a clothesline is.
Mohammed Bah Abba (1964–2010) was a teacher from northern Nigeria who developed the pot-in-pot refrigerator in the 1990s. This refrigerator is extremely simple and does not require power, making it suitable for use in desert environments without easy access to electricity or repairs.
A 3 He/ 4 He dilution refrigerator is a cryogenic device that provides continuous cooling to temperatures as low as 2 mK, with no moving parts in the low-temperature region. [ 1 ] [ 2 ] The cooling power is provided by the heat of mixing of the helium-3 and helium-4 isotopes.
What are the risks of using a neti pot? Dr. Zara M. Patel, an otolaryngologist at Stanford Medicine, tells Yahoo Life that the biggest risk of using a neti pot is not the device itself but what's ...

The matki/matka, a traditional Indian porous clay container used for storing and cooling water and other liquids. The botijo, a traditional Spanish porous clay container designed to cool the contained water by evaporation. Evaporative coolers, which can significantly cool a building by simply blowing dry air over a filter saturated with water.
