Sweden (TGW) – Using warm milk from over 1100 cows, a castle in Sweden heats itself in an environmentally friendly way.
The castle’s herd produces some 8000 gallons of milk each day. The milk leaves the cow at about 99 degrees Fahrenheit and is quickly cooled to 37 degrees so it won’t spoil.
The herders at the castle have developed a way to capture the lost heat, and use it to heat the building and heat water.
