Extensive research into droughts revealed an increase in soil evaporation and trans-evaporation (plant and soil) due to the increasing temperatures. Airdrop Irrigation works to provide a solution to this problem. Moisture is harvested out of the air to irrigate crops by an efficient system that produces large amounts of condensation. A turbine intake drives air underground through a network of piping that rapidly cools the air to the temperature of the soil where it reaches 100% humidity and produces water.
