Comments Off on Desert Twins produce water through condensation in driest place on Earth

One in 10 people on Earth lack access to safe water , which is why artist Ap Verheggen has been working so hard to address water scarcity over the last decade or so. He and the rest of the SunGlacier team, invited by the Dutch Ministry of Defense, recently tested their idea of making water from thin air in what they describe as the driest, hottest place on the planet: the Sahara Desert . They were able to accomplish the feat solely with the power of the sun and a bit of basic physics. Take a closer look at their groundbreaking Desert Twins , designed specifically for this project, after the jump. From an ice-making leaf in the desert to a solar-powered desert waterfall , SunGlacier has pioneered creative, artistic approaches to the lack of water in Earth’s dry areas. They recently made water from air in Mali with the solar-powered Desert Twins, two devices built for the Sahara Desert test. One device makes water, the other houses an energy unit. Condensation enables the devices to create water.

According to the team, air in Mali on a summer day only has around half the water vapor of a dry summer day in the Netherlands. They faced several days of challenges as they tinkered with their devices, adding insulation and re-configuring cooling air streams before they finally succeeded in producing any water. The team knew their design could operate in ideal conditions, but the Mali success shows it can work just about anywhere in the world. SunGlacier says their device is “probably the world’s first artificial water well to work entirely off the grid .” SunGlacier intends to keep improving their technology, and say in the future they plan to focus on cleaning and enriching water with salts and minerals, and water storage. Their goal is to build a machine that is able to operate without electricity or a liquid water source, much like a well. + SunGlacier Via SunGlacier Images courtesy of SunGlacier

Comments Off on Innovative Water-Gen machine harvests up to 825 gallons of clean water from thin air in a day

You might remember from grade school science class that water vapor is all around us, taking part in a continuous cycle that fills the clouds, lakes, and oceans with moisture. The people at Water-Gen have found a way to draw this moisture out of the air to produce clean drinking water for those who have none. The device can yield up to 825 gallons of water per day, making it a necessity for inhabitants of a warming planet. Water-Gen ’s unique system is built to harvest condensation out of thin air. Three sizes of these water-generating machines use an array of plastic “leaves” that funnel warm and humid air through the device. The largest unit can produce 825 gallons of water per day at 80 degrees and 60 percent humidity, its medium device can yield 118 gallons, while its smallest device – for the home or office – can produce 4 gallons each day. All that is required is a connection to an energy source, yet it is estimated that each gallon will only cost 10 cents in energy usage. Related: 6 innovative, life-saving designs for clean drinking water “Places that do not have drinking water in pipes are usually hot and humid,” CEO and founder Arye Kohavi told Business Insider . Luckily, the system thrives on hot and humid environments, making it a perfect match for areas facing water scarcity . The company is already engaged in talks with several different governments about how the system can benefit those who need water-generating machines, instead of purification systems. “Water from air is for places that you don’t have any water to filter,” Kohavi explained. And, as climate change persists, the need for clean drinking water will surely increase. + Water-Gen Via Business Insider Images via Water-Gen

Comments Off on New Dutch housing model lets students stay at a senior living home for free

At Humanitas Deventer , an independent living home for seniors in the Netherlands , it’s not uncommon for an 80 or 90-year-old resident to have a 27-year-old neighbor. Students can live at Humanitas Deventer for free. All they have to do in return is spend 30 hours each month being a ” good neighbor .” 27-year-old Patrick Stoffer is a graduate student at Saxion University. He’s one of about five students who live at Humanitas Deventer. During their 30 volunteer hours, the students teach the retirees skills like how to send an email or Skype, or just share a meal and a conversation. Many of the students have formed profound relationships with their elderly neighbors. Related: This nature-filled community is a smart housing solution for Singapore’s aging population “At first I thought I’m just gonna help out a little bit, but you find out that these relationships are deeper than you would expect,” Stoffer said in a video . One of his roommates is 89-year-old Harry, a retiree, whom Stoffer describes as a “joker” who “knows how to handle the ladies.” They’ve become close friends. One new aspect of living at Humanitas Deventer for the students is the closeness to death . Stoffer described how one of his friends in his hall passed away. While he’s had to confront death, he’s learned death is “also part of life.” A lack of affordable housing in other university towns has inspired communities in other areas around the world to adopt intergenerational living models. One similar community is Judson Manor in Cleveland, Ohio, where music students live in a 1920’s luxury hotel converted into a senior home in exchange for playing music for the elderly residents. Urban design student Jurriën Mentink shared his experiences at Humanitas Deventer in this TEDx talk – where do I sign up? + Humanitas Deventer Via AJ+ Images via Humanitas Deventer and Humanitas Deventer Facebook

Comments Off on Eole Water’s Wind Turbine Generates Fresh, Clean Drinking Water from Condensation

Wind Turbine Image from Shutterstock In remote areas without access to fresh drinking water, there is often the dual concern of a lack of electricity — which is what makes French company Eole Water’s innovative wind turbine, the WMS1000 , so intriguing. Eole’s modified turbine not only harnesses wind for energy, but includes a compressor similar to that of a dehumidifier , which pulls in air to generate condensation. The condensate is then harvested to produce up to 1000 liters of fresh, clean drinking water each day.

10 eco friendly gadgets that produce water from air

Comments Off on 10 eco friendly gadgets that produce water from air

Balakrishnan Ramachandran: atmospheric condensation water vapor in air condenses when it cools below dew point Water availability has already become a major concern area for humankind. Some UN studies already estimate that some 1 billion people worldwide do not have access to adequate drinking water. Water borne diseases already account for over 50% of preventable human ailments in the poorer regions of the world.Even in the more advanced regions of the world, municipal water supply is no longer considered safe enough to drink. This has spawned a $ 50 billion packaged drinking water industry. The atmospheric air always has water vapor present in it. This is part of the Hydrologic cycle, where water evaporates from the seas and other water bodies, the vapor is carried by air into the upper atmosphere where it forms clouds which then condense into water as rain or snow. The total water vapor in the atmosphere is so large that it can meet all of human water needs. Scientists and engineers are attempting to find means to extract water from the air without waiting for the natural rain cycle. The two basic processes to extract water from air are cooling condensation and wet desiccation. Cooling condensation is the familiar sight we see of water droplets forming on the outside of a bottle or glass of any cold liquid. The air in the atmosphere is cooled below its dew point by contact with the bottle or glass,causing the water vapor in the air to condense. Desiccant cooling is illustrated by the fact of common salt in a salt shaker becoming damp by absorbing water vapor from the air.Many commercial air-to-water devices have now become available. Some alternative approaches are also being attempted. An air-to-water industry appears to be developing Condensation cooling 1. Using natural stone structures for condensation Examples of condensation cooling exist even from early human civilization. In some parts of Europe and the Middle East, there are 10 meter tall beehive-like stone structures dating from the 19th century, called air walls. The stones cool rapidly in the night. When moist air comes in contact with these stones, the condensation yields water that is collected in troughs inside the structure and used for drinking and washing.In France, these structures were also used in some vineyards. 2. Using water nets for condensation This is the modern adaptation of the ancient stone walls for water harvesting. At a village named Cabajane in sub-Saharan Africa, a team from the South African Agricultural University helped the villagers string up plastic nets across a mountain pass. The clouds and fog through the pass, condensed water on the nets, which ran down through plastic pipes to be collected in a tank. Several hundred liters of potable water became available to the village from this simple device , where they earlier had to walk over 2 km to the nearest stream. This experiment is now being replicated in other villages in sub-Saharan Africa and also in Chile and in some places in Nepal. 3. Foldable structure for water harvesting Two Israeli architects, Joseph Cory and Eyak Malka have designed this foldable triangular structure, named WatAir, that is said to imitate the leaves of a tree to condense atmospheric water vapor and collect it into a tank. The structure folds into a a package of 1 meter maximum dimension and 3.5 kg weight, that the designers claim can be erected anywhere, to harvest atmospheric water. 4. Max Whisson’s Gust Water Trap Dr Max Whisson of Perth, Australia has come up with a wind turbine design that produces water by condensation, instead of electricity. The wind turbine has vertical blades and is mounted on a swivel with a wind vane tail, so that it can turn to face the direction of the wind. When the turbine turns, the wind gets forced into the hollow tower. The air passes over a refrigerant compressor driven by the wind turbine and condenses into water, that flows into tanks at the base of the tower. A company named Water UN Limited has been formed to commercially apply this technology. 5. Windmill to make water from air The company Dutch Rainmakers of Netherlands has installed a windmill Surinam to produce water instead of electricity. In their design, the air is forced through a heat pump, where the water vapor condenses. This heat pump replaces the refrigerant compressor. The wind mill is said to produce 5000-7000 liters a day, a real boon in a place where the groundwater is brackish. 6. Refrigerant based condensation The modern condensation cooling devices, generally use a refrigeration coil to provide the cooling. Many manufacturers worldwide have come up with condensation cooling machines that work on the following principle.Inlet air is filtered to remove dust and suspended particles using fabric filters. This air is passed over coils containing cold refrigerant gases. The condensate water is collected in a stainless steel tank and exposed to ultraviolet light for about 30 minutes to remove bacteria and then filtered through an active carbon filter. The typical cost for a model that produces 20-25 liters a day is about $ 1500 and these machines consume about 500 watts of electricity. These condensation machines are styled like the conventional water coolers installed in offices and public places, and are intended to be used in such locations. One of the largest companies in this field appears to be Air Water Corporation of Miami Beach, Florida which makes a range of machines from the 25 liter per day single office type capacity to larger 2500 liter per day trailer mounted machines complete with their own diesel power generator that can be installed at a construction site or even in a village as they have done in Jalmudi in India. Air Water Corporation says that its products are sold in 21 countries through local affiliates. Another company that has targeted the home user with this technology is Element Four Technologies Inc.,of British Columbia, Canada which has launched an attractively packaged product they have named the WaterMill. The home model is dsigned to produce 11 liters of water per day enough to meet the drinking needs of a small family. The air intake and condensation is planned to be mounted outside the home and the potable water tank inside the home ( like a split air-conditioning unit). An upgraded model for 20 liters per day in planned. However, there are many companies with product variants for this market. 7. DRIPS for growing crops with water from air Two high school students from San Francisco, with mentoring by professors from the University of California, Berkeley, have proposed this system for water harvesting from air. DRIPS stands for Deep Root Irrigation Precipitation System and is made of a 1 foot diameter, or larger, plastic or aluminum conical surface mounted on a hollow tube that is buried 1.5 feet into the ground. The plastic or aluminum surface cools in the night and in contact with air, causes water droplets to condense. This water, by capillary action aided by small ribs on the cone, drains into the ground. The depth of 1.5 feet prevents this water from evaporating back into the atmosphere and helps nourish the roots of plants. This method of water harvesting has been demonstrated to grow potatoes. 8. Fraunhofer Institute’s brine tower The Fraunhofer Institute of Interfacial Engineering and Biotechnology (ICB) in collaboration with the company Logos Innovationen is working on this concept of a tall tower like structure down which hygroscopic brine solution runs down. This brine in contact with air absorbs moisture and runs into a tank at the base of the tower which has a slight vacuum. The tank is heated with solar collectors that causes the brine solution to boil. The vacuum in the tank lowers the boiling point of the brine solution.The water absorbed from the air evaporates and is led out through a tube filled with water. This water column maintains the vacuum in the tank without the need for a vacuum pump. The brine is recovered and pumped up again to flow down the tower. 9.Liquid desiccant for water harvesting from process air Sciperio Inc., an Orlando, Florida based technology is working on using liquid Lithium Chloride as the desiccant to remove water from air. Their finding is that this is more energy efficient than using refrigerant based water harvesting technology and have proposed using this for water extraction from air in process plants for industrial use, rather than for drinking. 10. Use of solar energy for regenerating the desiccant One variant of the use of wet desiccation by the company A2WH of Atlanta, Georgia which uses a proprietary desiccant for water vapor absorption. This desiccant is heated by solar energy to expel the absorbed water. The unit, installed outdoors, also has photo voltaic panels to generate the electricity needed for operating the units pumps and valves. A2WH says it has models both for the individual home and for irrigation of farms.

Ruchika Pahwa: Myrtle Beach International Airport Designed by inFORM Studio Presenting a fresh example of an excellent architectural design, inFORM Studio has been displaying state-of-the-art skills through its work on the Myrtle Beach International Airport’s project. Worth $129 million, this project includes the Terminal Expansion Capacity Program. Under this program, you would soon be able to see a new terminal added to the existing airport facility. inFORM Studio has taken up the tight-budget task of developing and beautifying this airport terminal near Myrtle Beach in South Carolina, U.S. The project aims at the development of this new terminal for handling the airport’s operations in a better manner, as well as adding gates that could serve the extra passenger load. Picture Gallery Myrtle Beach International Airport Myrtle Beach International Airport Designed by inFORM Studio The new airport terminal is being designed to include a ticketing lobby. It also aims to have facilities to handle TSA screening and all kinds of baggage handling and claim operations. The terminal site has to be connected to the existing airport facility through a connector bridge. It has to have a five-gate concourse and an additional gate that would be incorporated into the connector bridge for managing the circulation space in the most efficient manner. The complete project area includes a space of 218,661 square feet, and an eight-member team of designers has been working hard on the project. The designers’ team includes Anna Haezebrouck, Cory Lavigne, Gina Van Tine, Jeremy Ervin, Jordan Whitted, Kenneth Van Tine, Michael Guthrie and Robert Miller. While designing the new airport terminal, the inFORM Studio team has been considering a range of climatic and environmental factors – whether these be providing a cover from sunlight and still following natural lighting options, or saving energy and introducing displacement ventilation options for offering more comfort to occupants. Due to the building’s form itself, an overall energy requirement reduction by 14% has been observed, in comparison to the existing baseline terminal energy usage over last 30 months. The comprehensive architectural design focuses on a more swift circulation pattern for the ease of passengers traveling inside the terminal. This huge structure is effectively being shaped and designed by inFORM Studio’s designers who have specialized architectural styles and who are effectively contributing to make the new terminal a success story. So, if you are a regular flier and keep visiting the Myrtle Beach International Airport often, you will soon get to experience a modern, more managed, special architectural style structure. Hopefully, this new airport terminal reduces some of your travel-related worries and makes operations smoother for your delightful travel experience! Via: Arch Daily
