Google uses toilet water to cool its servers!
We all know google has secrets behind their doors, alot of them. Slides instead of stairs for the staff, google segways, google bikes, google everything. But there are some secrets not even the staff know about, and thats whats going on inside their server halls!
First off, to save money and the nature Google has started using sewage water that cirkulates through their servers to cool them. This is quite revolutionary, since it really does save the nature, big time. Earlier they used drinking water flowing through the server computers and then out the drain, but then they (obviously) realised their servers dont need water clean enough for drinking to cool their systems. So now they use filtered sewage water! Great way to cool your equipment, save nature, and some money too.
