Water harvesting through condensation is not new, but an additional result of the cooling process (to harvest water through condensation) is cold air.

Most conventional water harvest systems consider the resulting “cold air” as a waste product. In the CC-Airwell system (subject of an international patent) the value of this waste cold air is made clear. With sufficient volumes we can return 2°C “cold air” out of the CC-Airwell and into the surrounding environment where the air is considerably warmer. At 2°C the return air is well under the dew point and creates “ground condensation”: not only fog, but also drizzle – we let it rain.

This ground condensation (just 10 drops per m2 , per second) seeps into the soil, cooling the warm soil and is then collected at a 30 m depth. These “10 drops of water” over 2 km2 results in 20,000 litres of water per second and works 24 h per day, 365 days a year, adding up to 1.7 billion litres of water per day. This water is suitable for use as drinking water and irrigation water, for forests, and wild animals or for aquaculture.  It also acts as a climate cooling system, desert greening and carbon capture initiative.
