HOW TO MAKE ECO-COOLER AT HOME The recommended eco cooler design is one of the most environmentally friendly and cost-effective solutions that have the capability of reducing the temperature of the room by about 5oC. Step 1:Collect waste plastic bottles from dumping sites What is needed include: 1. Lots of plastic bottles 2. A cardboard 3. Pen-knife or scissors Step 2: Cut holes on the board, with sizes equal to the rim of the bottle Step 3: Carefully cut away the bottles in half crosswise Step 4:Mount the cut bottles on the cardboard by screwing on the other side How Eco-cooler Works: The airflow velocity ensures that the system maintains a thermal equilibrium in the room by removing any temperature gradient in the room.
