Some notes I took talking to Bill

• Cooling tower - water. The rotation cools down water by around 11 F -> then this cools the refrigerant.
• The water that comes out it cold and goes into the buildings to cool down the buildings.
• The water that falls never leaves this plant.
• The quality matters - it is clean or it would cause corrosion or scaling.
• They have filtration sustem, it swirls the water and blows out the bugs and soil.
• Once a year they change the water and it is not drinkable but wouldn't kill you.
• They also use phosphanate to keep the dissolved matter dissolved.
• The closed system, water is cleaner than the water in cooling tower.
