First of all I want to tell all of you that this entry is so difficult to find it reference. Thank you to all of you because give me this “beautiful topic”. But I try my best to find it. Whether it is right or wrong, you analise it by yourself.
This design has raised some questions regarding how much weight the gel can hold and how the gel can affect different foods in terms of temperature and texture.
While the gel concept contributes a zero-energy appliance, it is still a ways off from becoming a realistic part of any household. On the other hand, a solar-powered refrigerator provides both zero-energy cooling and is currently saving the lives of those who are limited by a lack of available refrigeration for the storage of vaccines.
The solar-powered refrigerator was developed by Appropriate Technology Collaborative (ATC), which is a non-profit organization that works to develop technologies to improve the lives of people in developing countries.
The ATC solar-powered vaccine refrigerator was made for certain parts of the world that requires vaccines but have no source of refrigeration to keep them from spoiling. Due to this lack of refrigeration, more than half of the vaccines go bad before they are even administered, which leads to the death of millions of lives and the loss of billions of dollars.
This refrigerator requires no electricity and contains no valves or moving parts, making maintenance an easy task. The inexpensive design provides cold storage for vaccines in developing countries, depending solely on sunlight to make it freeze. According to the ATC, the ATC Solar Vaccine Refrigerator is a robust, easy to maintain technology that can be made in the country or region where it is to be used and is made out of simple materials that can be found in most cities like steel, charcoal and ethanol or methanol.
So….. what is the barriers of this refrigerator actually???
