Enwave (http://www.enwave.com/) - Uses cold energy from Lake Ontario to cool buildings in downtown Toronto, reducing electricity usage by 90%. Deep Lake Water Cooling is sustainable, clean, renewable and can continue to operate during blackouts.
- Hydrothermal Cooling: Improving on Air-Conditioning (http://www.treehugger.com/files/2007/06/hydrothermal_cooling.php) - Canadians living in Toronto have found a cheap and sustainable way to stay cool, drawing on the large supply of cold water from Lake Ontario to power their air conditioning systems. With plans to connect up to 52 more buildings, the project is expected to reduce Toronto's energy needs by 61 megawatts. (TreeHugger; Jun. 11, 2007)

Tapping Thermal-Gradient Cold: Free Power or Planetary Suicide? (http://pesn.com/2005/06/03/9600105_Thermal_Gradiant_warming/) - Advocates of tapping ocean depths for stored cold promise a clean future. But is it really environmentally friendly, or a slippery slope into unrecoverable catastrophe? (PESN; June 3, 2005)

evelop (http://www.evelop.nl/en/projects/SWAC/technology.asp) - SeaWater Air-Conditioning is a system that uses cold seawater (between 6 and 10°C) from a depth of approximately 700 m as a coolant for air-conditioning systems in buildings situated within a close radius. The system can reduce total electric energy consumption and related CO2 emissions for cooling by up to 90%
