Paraguay. With the aim of learning how to manufacture solar panel refrigerators to refrigerate the food of the indigenous people of the Chaco, several institutions in Paraguay have joined forces and have launched the training program "Introduction to solar cooling by absorption".
The Catholic University (UCA), the Faculty of Engineering of the National University of Asunción (UNA), both in Paraguay, the National University of General Sarmiento in Argentina and the Itaipu organization, are the initiators of this process.
The program lasts 40 hours and consists of training for the manufacture and assembly of this type of refrigerators whose final destination will be their installation in places where electricity does not reach, in this case the jungle area of the Chaco.
According to Rodolfo Echarri, researcher at the Institute of Human Development of the aforementioned Argentine university and instructor in this initiative, the idea is to use very low technology to manufacture this equipment.
Copper pipes will be used for water, activated carbon and methanol. "The refrigerators will allow the indigenous people to preserve food, in addition to making ice for various uses," explained the professional, who added that each prototype would cost just over 600 dollars.
