Sun + Soda Bottles = Hot Water

People all over the world are figuring out ingenious ways to do things with the heat of the sun and used bottles!

Welcome to Southern Brazil, where we find this home made solar water heater, that makes use of plastic bottles, black painted milk cartons and PVC pipes.

There are 200 used soda bottles and 200 liters of water in the tank. The thermometer tells us this water is heated to about 42 degrees C, about 106 degrees F.

Hot water using no electricity or fossil fuels!
