Green Self-Powered Air-Water Harvester

Clean water and sustainable energy sources are needed for social and economic progress of a country. The developing countries are already facing the crises of energy and deficiency of drinking water. The issue is more severe for the people living in remote areas of developing countries like Northern Belt of Pakistan. In this paper, a novel self-powered green water harvesting system is proposed. An innovative condenser is designed which is unique in terms of its geometry and can work fine in harsh environmental conditions. Water condenses from humidity present in the air when the temperature falls below the dew point. To create this environment, the technique of Thermo-Electric Cooling is used. When the temperature of the surface falls below the dew point, water condenses from humid air touching the surface. The system is powered by renewable energy which is extracted from the air using a wind turbine. Temperature, humidity, water productivity and wind speed are constantly monitored.
