Abstract: An automatic plant watering device includes a thermoelectric module with a cold face that can be energized to drop its temperature below 32 degrees F. A condensation member is thermally connected to the cold face and has a wall exposed to ambient air for water vapor to condense on and freeze when the module is energized. A water collection chamber positioned below the exposed wall is configured to hold collected melt water from the exposed wall until a collected melt water temperature has risen above 32° F. A moisture sensor is used to initiate a chilling cycle controlled by a controller to energize the thermoelectric module for a period of time in excess of an hour to cause a build-up of frost on the exposed wall and thereafter to deenergize the thermoelectric module to permit the temperature of the exposed wall to rise above 32 degrees F.

Abstract: A dehumidifier/cooling apparatus for use in a room having an elevated temperature and/or humidity is provided which utilizes the natural coolness of tap water to condense water vapor from the air or merely cool the air. The tap water line is diverted into a heat exchanger upstream of a hot water heater to dehumidify and/or cool the air in the room the air and remove the latent heat given off during condensation to cool and/or dehumidify the room air and to pre-heat the water entering the hot water heater. An air moving device powered solely by water moving through the tap water line directs a flow of air through the heat exchanger.

Abstract: A method and system for condensing water from ambient air at an ambient temperature. A dew extracting device with a dew extraction zone having a surface has the surface chilled to below dew temperature via a fluid refrigerant. The chilling of the surface is terminated once condensed liquid water is detected on the surface. The liquid water is removed from the surface and a temperature of the surface is allowed to rise above the dew point temperature, but remain below the ambient temperature. Then the process repeats to obtain additional liquid water.

Abstract: A method and system for condensing water from ambient air. A dew extracting device with a dew extraction zone having surfaces has the surfaces chilled to below dew temperature for a first period of time. An air moving device directs a flow of air over the chilled surfaces so that liquid water condenses on the surfaces, raising the temperature of the surfaces. The chilling of the surfaces is terminated for a second period of time and liquid water is removed from the surfaces and heat of condensation is removed from the dew extraction zone. Then the process repeats to obtain additional liquid water.

Abstract: A dehumidifier for use in an industrial or commercial building in conjunction with an air conditioning system is provided which utilizes the natural coolness of tap water to condense water vapor from the air. The tap water line is diverted into a heat exchanger upstream of the air conditioner evaporator coils to dehumidify the air and remove the latent heat given off during condensation to reduce the work load on the air conditioning system.

Abstract: A method and apparatus for automatically watering vegetation whereby the water requirement of vegetation is constantly monitored and selectively condensing water vapor out of the atmosphere onto cooled condensation member and collecting the condensed moisture for application onto soil containing vegetation. Various accessories are provided to automatically feed the vegetation and distribute water to the soil containing the vegetation.
