How To Get Fresh Water Out Of Thin Air

How To Get Fresh Water Out Of Thin Air
Image Credit: MIT Fog-harvesting system developed by MIT and Chilean researchers could provide potable water for the world’s driest regions. CAMBRIDGE, Mass. — In some of this planet’s driest regions, where rainfall is rare or even nonexistent, a few specialized plants and insects have devised ingenious strategies to provide themselves with the water necessary for life: They pull it right out of the air, from fog that drifts in from warm oceans nearby. Now researchers at MIT, working in collaboration with colleagues in Chile, are seeking to mimic that trick on a much larger scale, potentially supplying significant quantities of clean, potable water in places where there are few alternatives. Fog harvesting, as the technique is known, is not a new idea: Systems to make use of this airborne potable water already exist in at least 17 nations. Fog-harvesting systems generally consist of a vertical mesh, sort of like an oversized tennis net. Credits: Related:  Solar Water StillsMini Eco Solutions

Solar Water Still Construction You can use stills in various areas of the world. They draw moisture from the ground and from plant material. You need certain materials to build a still, and you need time to let it collect the water. It takes about 24 hours to get 0.5 to 1 liter of water. Aboveground Still To make the aboveground still, you need a sunny slope on which to place the still, a clear plastic bag, green leafy vegetation, and a small rock (Figure 6-6). To make the still-- Fill the bag with air by turning the opening into the breeze or by "scooping" air into the bag. To get the condensed water from the still, loosen the tie around the bag's mouth and tip the bag so that the water collected around the rock will drain out. Change the vegetation in the bag after extracting most of the water from it. Belowground Still To make a belowground still, you need a digging tool, a container, a clear plastic sheet, a drinking tube, and a rock (Figure 6-7). To construct the still-- Back to Water Procurement

How to Make a Solar Still - DIY With high energy costs and a warming planet that needs cleaner fuel sources, the time has never been better to get involved with solar energy. DIY Solar Projects (Creative Publishing International, 2011) by Eric Smith contains how-to instructions for many achievable, clever projects you can make and install in order to create your own solar lifestyle. Hundreds of people are doing it, and you can too. The following excerpt is taken from the chapter, “Solar Still.” You can purchase this book from the MOTHER EARTH NEWS store: DIY Solar Projects. Make Your Own Distilled Water Make your own distilled water from stream or lake water, salt water, or even brackish, dirty water, using these DIY Solar Still Plans. Distilled water is not just for drinking, and it’s always worth keeping a few gallons of it on hand. • Always refill the lead-acid batteries used for solar energy systems or automobiles with distilled water • Steam irons become clogged with mineral deposits unless you use distilled water

Solar Oven Transforms Salt Water to Drinkable Water Of all the water on earth, only an incredibly small percentage is available for us to use and drink… the remainder is largely highly salty water, or at best brackish water with unhealthy levels of salt. For much of the western world, where water is plentifully available and piped right to your location this is hardly an issue for concern; but in countries where limited water availability is compounded by heavy pollution and miles of walking each day to collect it, the situation becomes a lot more dire. Enter Italian designer Gabriele Diamanti and his fascinating Eliodomestico. See Also Water Down: Detailing the Global Water Crisis The deceivingly simple device transforms salty water to clean drinkable water in one day of sun exposure – just by filling the top-mounted black boiler with salty water and tightening the cap. Diamanti was inspired to create the project by his own extensive travel and by his friends’ work with NGOs. ↬ fastcodesign

Global Buckets - Nightly DIY Solar Still How To Make Your Own Distilled Water Make your own distilled water from stream or lake water, salt water, or even brackish, dirty water, using these DIY Solar Still Plans. With just a few basic building materials, a sheet of glass and some sunshine, you can purify your own water at no cost and with minimal effort. Distilled water is not just for drinking, and it’s always worth keeping a few gallons of it on hand. Clean water free of chemicals and minerals has a number of valuable uses: • Always refill the lead-acid batteries used for solar energy systems or automobiles with distilled water • Water delicate plants like orchids with distilled water; minerals and additives like fluoride or chlorine that are present in most tap water can harm plants • Distilled water mixed with antifreeze is recommended for car radiators, as it’s less corrosive • Steam irons become clogged with mineral deposits unless you use distilled water How to Make a Solar Still The operation of the distiller is simple. 1.

How To Build A Solar-Powered Still To Purify Drinking Water The author’s solar still, with one pan in it. The still actually has room for two of these. Note that the glass top is at an angle, allowing the water to flow down to the catch tube. Everyone agrees that water is needed for survival and articles abound for how to find water and purify it for drinking. But all those articles have one thing in common: They are talking about purifying water from biological hazards. Normally, the biggest hazards we face from drinking water are microorganisms: bacteria, protozoa and other parasites which can enter our system and make us quite sick. While those biological hazards are important, they aren’t the only thing we can find in our drinking water. Distillation is a simple process, although it can be difficult to accomplish in quantity. The really great thing about distillation is that nothing else evaporates with the water. A solar still, like many solar collector devices, consists of a glass-covered box, which is painted on the inside.

Simple tree branch filter makes dirty water drinkable To turn dirty lakewater into drinkable H2O, peel away the bark from a nearby tree branch and slowly pour water through the wood. According to new research, this neat, low-tech trick ought to trap any bacteria, leaving you with uncontaminated water. Okay, time for a little tree physiology. To get water and minerals up a tree, wood is comprised of xylem, porous tissue arranged in tubes for conducing sap from the roots upwards through a system of vessels and pores. Turns out, the same tissue that evolved to transport sap up the length of a tree also has exactly the right-sized pores to allow water through while blocking bacteria. As Karnik’s team finds, a small piece of sapwood can filter out more than 99 percent of the E. coli from water, at the rate of several liters per day. To study sapwood’s water-filtering potential, the team collected white pine branches and stripped off their outer bark. They tested their improvised filter using water mixed with particles ranging in size.

Amazing Low-Tech Water Harvester Even in places where there’s a severe lack of water, there’s one thing every place has. Air. And even in the most arid of climes, there’s moisture in the air, even if it’s not enough to be felt on your skin. With a deceptively modest design, Airdrop filters hot environmental air through a turbine, feeding it through a copper tubing system—with copper wool to maximize surface area—and into the earth where it cools and releases moisture. Okay, that’s just genius and badass. Via Water Solar Stills: Clean Drinking Water In a situation of survival the Solar Still ( AKA Vapor Still ) can provide a short to medium term source of fresh drinking water from seawater, rivers and ponds. This important and neccessary piece of survival equipment has been used by the military and yachtsmen for many years.

Portable Solar Desalination 'Plant' That May Aid In Third World Water Woes By Meera Dolasia on September 14, 2012 CCSSNAS-1NCSS-3Word Search 'Water, Water everywhere, not a drop to drink' - That, unfortunately, is the situation faced by millions of residents in developing countries who are surrounded by oceans, but have no access to fresh drinking water. The Eliodomestico works just like a coffee percolator except, upside down. The Eliodomestico is then placed in a sunny area causing the liquid in the container to heat up and turn to steam. The best part is that this portable device can desalinate up to five liters of water at a time and after the initial purchase price estimated to be about $50 USD, costs nothing extra to operate.

This Device Provides Clean Water for Pennies a Day Photo: WaterconePassive Solar One Step Water Condensation FTW!We wrote about the Watercone back in 2004, but considering how much TreeHugger's audience has grown since then, it's likely that only a handful of you were reading the site back then. I think it's time to have a second look at this very clever device that has the potential to help provide clean drinking water for millions of people who are lacking access to clean water (or if they do, maybe the access is intermittent and they could use a plan B). This could save many lives for sure. Photo: WaterconeStep #1: Pour salty / brackish Water into pan. Photo: WaterconeStep #2: The evaporated Water condensates in the form of droplets on the inner wall of the cone. Photo: WaterconeStep #3: By unscrewing the cap at the tip of the cone and turning the cone upside down, one can empty the potable Water gathered in the trough directly into a drinking device.
