Homemade solar hot water heater in Brazil
The ingenuity of man never ceases to amazes us! By using recycled bottles, black painted milk cartons, and pvc pipes- this man in southern Brazil made a homemade solar hot water heater.
There are 200 used soda bottles and 200 liters of water in the tank. The thermometer tells us the water is heated to 42 degrees C, about 106 degrees F.Hot water when you want it- using no electricity or fossil fuels. Cool!
