Deep Lake Water Cooling System

Enwave’s Deep Lake Water Cooling is now cooling the downtown core of Toronto. Cold water is drawn from the icy waters 83-meters below Lake Ontario. The water pipes cool a closed system of water pipes that cool downtown. Enwave has enough capacity to air condition 32 million square feet of building space capacity: approximately 8000 homes. 40,000 tons of carbon dioxide are removed from the air. Enwave has a video online explaining the system in more detail. (via Metafilter)
