Could this simple design save the planet?
| Innovative irrigation system conjures water out of thin air | Technology News Blog - Yahoo! News AirDrop uses a turbine to push air into its network of pipes underground, which is quickly cooled to soil temperature, thereby creating an environment with 100% humidity. Condensation then takes place naturally, and water produced from the air is collected in a tank that's kept underground to prevent evaporation in hot areas. Crops are watered by pumping water directly from the tank. AirDrop is completely self-sufficient, and needs no external source of energy to work. During especially breezy times, the winds propel the turbine that drives the air into the tubes. But during calm days without winds, a solar panel collects the energy needed to move the turbine. |
