SkyCool

Air conditioning is a major driver of energy use globally, particularly in hot climates and during peak hours. Current approaches to this $50 billion market require the input of large amounts of electricity and water, and have remained largely unchanged in their fundamental approach for decades. SkyCool will develop a commercializable prototype of a radically efficient water-cooling module that can be used to passively reject heat to outer space from residential and commercial buildings. The modules will generate water 3-5°C below air temperature with zero water losses and will only require electricity to pump water through them, thus allowing SkyCool to demonstrate remarkably efficient air conditioning systems. SkyCool plans to aggressively move towards commercialization by fabricating modules capable of cooling at a scale relevant to residential and commercial buildings, testing those modules’ performance in real-world building scenarios, and addressing key questions of cost and durability.
