Abstract: Provided herein are water and carbon dioxide harvesting systems, as well as methods using such systems, for capturing water and carbon dioxide from surrounding air. The systems and methods use water capture materials to adsorb water from the air and carbon dioxide capture materials to adsorb carbon dioxide from the air. For example, the water and carbon dioxide capture materials may be metal-organic-frameworks. The systems and methods desorb the water in the form of water vapor and the carbon dioxide. The water vapor is then condensed into liquid water. The water and carbon dioxide generated can be used in farming systems, including hydroponics and vertical farming systems.

Abstract: Atmospheric moisture harvester systems include two beds with water capture material, such as metal-organic framework (MOF), a heater, two fans, and a condenser having two sides, operatively configured into adsorption and desorption modes, wherein the MOF beds are interchangeable to cycle between the desorption and water adsorption modes. The systems may further include a photovoltaic panel powering the fans and condenser.

Abstract: Provided herein are refrigerator systems integrated with an atmospheric water harvesting unit, as well as methods using such systems. The atmospheric water harvesting unit serves as a water supply for the refrigerator system by capturing water from surrounding air. For example, the water capture materials may be metal organic frameworks. The systems and methods desorb this water in the form of water vapor, and the water vapor is condensed into liquid water and collected. The liquid water is suitable for use as drinking water.

Abstract: Provided herein are atmospheric water harvesting systems that are tailored with an optimal adsorption threshold, based on energy cost and water availability considerations. The systems include a plurality of adsorbent modules, each containing metal organic frameworks of various adsorption thresholds. Such a design enables real time adjustment to achieve optimal harvesting conditions in changing atmospheric conditions, whether for daily or seasonal humidity variations.

Abstract: A water-harvesting system can operate with a material that can take up and release water with minimum energy requirements and powered by low-grade energy sources, such as sunlight, in order to potentially allow its deployment into households, especially those located in sunny regions. A water-harvesting method and system can include vapor adsorption using a porous metal-organic framework. In certain embodiments, the porous metal-organic framework can include metal-organic framework in ambient air with low relative humidity, typical of the levels found in most dry regions of the world.

Abstract: A trailing pig cleaning device is adapted to be dragged by a pig towing device. The cleaning device collects a predetermined quantity of debris. The cleaning device has a continuous outer surface portion of variable diameter urged into normal contact with the internal wall of the pipeline. The continuous outer surface portion presents a continuous upstream or leading edge portion for scraping debris from the cylindrical internal wall in advance of the outer surface portion. The device has a debris collecting surface portion extending radially inward from the outer surface portion for collecting the predetermined quantity of debris scraped from the cylindrical internal wall. The device has at least one debris and pipeline media bypass opening passing through the debris collecting surface portion permitting excess scraped debris to pass therethrough back into the pipeline and permitting media to pass thereby to propel the pig towing device.
