Night sky cooling is a natural process where an object on Earth radiates its heat into the coldness of outer space on a clear night, allowing it to cool down significantly. This phenomenon occurs because on a clear night, heat can easily escape through the atmosphere and travel to space, which is much colder than the air. This is also known as radiative sky cooling and has been used for centuries in the construction of ancient ice houses and is now being explored for modern applications such as passive cooling of structures.

CoolSky technology utilizes the unique properties of water to passively cool and heat a space. In the summer, CoolSky absorbs the heat from within your home during the day and radiates it into the ionosphere at night. In the winter, the cycle is reversed (using a solar powered pump) so that the system absorbs heat from the sun during the day and continues to radiate the heat into your home all night. In relatively dry climates, it can supply 100% of the cooling and 95% of the heating with virtually no external energy inputs- however, it can be effective in other climates as well.
