Evaporative cooling without electricity.

The heat just flows explained fan who is senior author of the paper. The system cools water flowing through pipes connected to an air conditioning system without requiring electricity by radiating excess heat from water into cold space. The specialized optical surfaces they developed are a major step toward applying this. If you have something that is very cold like space and you can dissipate heat into it then you can do cooling without any electricity or work.

Panels covered in specialized optical surfaces reflect about 97 percent of the sunlight while simultaneously emitting the surface s thermal energy through the atmosphere. For this reason the amount of heat flow off the earth that goes to the universe is enormous. Here are three methods of alternative refrigeration you can use without electricity. Methods of alternative refrigeration passive cooling.

Simple evaporative cooling devices such as evaporative cooling chambers eccs and clay pot coolers or pot in pot refrigerators are simple and inexpensive ways to keep vegetables fresh without the use of electricity. A wet bulb temperature is an indication of the amount of water vapor relative humidity in the air. Scientists cooled water without electricity by sending excess heat where it won t be noticed space.
