James Dyson Awards 2011 Winner: Edward Linnacre's AirDrop Irrigation

The Airdrop irrigation concept is a response to poor agricultural conditions in periods of severe drought. 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. The water is then stored in an underground tank and pumped through to the roots of crops via sub surface drip irrigation hosing. The Airdrop system also includes an LCD screen that displays tank water levels, pressure strength, solar battery life and system health.
