Seawater air-conditioning [SWAC] involves pumping cold water from oceans at depths of below 700 meters and temperatures of 3 to 5 degrees Celsius to the coast, where it can be used in cooling systems to produce cold air for buildings. The warmer water is returned to the ocean. While the initial capital cost of building SWAC systems is higher, energy costs to run it are low, the opposite of conventional air-conditioning.
