Abstracts: The purpose of the bicycle powered refrigerator is to allow someone to take a bike trip and keep their food or drink cold. This project used for poor neighborhood of Africa or asia where electricity is still a distant thing, moreover it can be extended to more useful device with help of windmill or flowing water. If its pedals joined with the turbine revolving using wind or water, we can use this refrigerator as an automatic machine. This project idea is for student of mechanical, electrical and physics students. When we pump out gases from the water box in the refrigerator by peddling a bicycle, we creates low pressure area inside the box, due to this low pressure, water starts evaporating and for the evaporation it needs heat from the surrounding which is our refrigerator in that way it cools our refrigerator. Absorption of steam is the property of the zeolite that’s why we use it in this experiment.
