Future Refrigerator which Does Not Require Compressor

Rathindranath Biswas


It sounds crazy a refrigerator made from a rubber band. But if one stretches a rubber band and hold it against one's lips, it will be noticeably warmer. If it is released, it cools. This simple "elastocaloric" effect can transfer heat in much the same way as compressing and expanding a fluid refrigerant in a fridge or air conditioner. Now, researchers have created a version that not only stretches the elastic band, but also twists it. Soon it would lead to greener cooling technology.
