With new water desalination method, potable water for disaster areas. 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.

Portable Solar Desalination 'Plant' That May Aid In Third World Water Woes

Now thanks to this ingenious portable ceramic desalination 'plant' created by Milan-based designer Gabriele Diamanti, there may be a viable solution. The Eliodomestico works just like a coffee percolator except, upside down. It comprises of two ceramic pieces that sit on top of each other. 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.

The ‘Solar Cucumber‘ is an innovative desalination plant design with the potential to help water-starved communities in coastal environments.

Solar Cucumber Harvests Fresh Drinking Water From the Ocean

The solar-powered desalination unit turns seawater to drinkable freshwater at source, rather than miles away from the scene of a shortage. The mini bus unit uses multiple-effect humidification to evaporate and condense seawater while removing its salt content. Multiple-effect humidification replicates the normal environmental water cycle. In the case of the Solar Cucumber, it uses solar power and reverse osmosis to separate water from other substances, including salt.

The system uses advanced non-stick-style materials to reduce maintenance and create an effectively self-cleaning system that produces fresh water and sea salt at source while reducing the need for costly and impractical transportation of water. . + Pauley The article above was submitted to us by an Inhabitat reader. Google Science Fair 2012: Powerless Desalination. New Invention Makes Ocean Water Drinkable. Susanne Posel Occupy Corporatism July 2, 2013 Chemists with the University of Texas and the University of Marburg have devised a method of using a small electrical field that will remove the salt from seawater.

New Invention Makes Ocean Water Drinkable

Incredibly this technique requires little more than a store-bought battery. Called electrochemically mediated seawater desalination (EMSD) this technique has improved upon the current water desalination method. Richard Cooks, chemistry professor at the University of Austin said : “The availability of water for drinking and crop irrigation is one of the most basic requirements for maintaining and improving human health.” Cooks continued: “Seawater desalination is one way to address this need, but most current methods for desalinating water rely on expensive and easily contaminated membranes. Kyle Krust, lead author of the study said: “We’ve made comparable performance improvements while developing other applications based on the formation of an ion depletion zone.

Desalination. Desalination, desalinization, and desalinisation refer to any of several processes that remove some amount of salt and other minerals from saline water.

Desalination

More generally, desalination may also refer to the removal of salts and minerals,[1] as in soil desalination, which also happens to be a major issue for agricultural production.[2] Salt water is desalinated to produce fresh water suitable for human consumption or irrigation. One potential byproduct of desalination is salt. Desalination is used on many seagoing ships and submarines. Most of the modern interest in desalination is focused on developing cost-effective ways of providing fresh water for human use.

Watercone. The Watercone is an ingenious device that can take salty water and turn it into fresh water using only the power of the sun.

Watercone

The nice thing about this device is it is bone simple, uses the sun instead of fossil fuel, and is cheap to make and easy to use. The Watercone is surprisingly a cone, that you place over a pan of salty water (or over a marsh, or any damp ground) leave it out in the sun, water evaporates, the condensation trickles down the side of the cone, at the end of the day you flip it over, remove the cap at the top and drink the water. This device has the potential to really do a lot of good for a lot of people. So many people live in areas where the ground water has been polluted by salt incursion due to over pumping, or in areas that simply don’t have large fresh water sources (south pacific islands, sub-Saharan Africa, south-east Asia). They claim that on average one Watercone can produce one liter of water per-day. Waterpyramid. Usage The WaterPyramid is used in tropical remote regions to desalinate saline water and to harvest rainwater.

The technology is best used were abundant radiation of the sun and free ground space is available. Target groups Remote rural villages in desert areas, tropical regions and island ridges lacking sufficient fresh drinking water. Mostly Developing Countries. Production On yearly basis approximately 600 m 3 of fresh drinking water is produced: 300 m 3 distillate and 300 m 3 as a result of rainwater harvesting. Technology: Unique and rewarded by the World Bank with the Development Marketplace Award 2006. Benefits of WaterPyramid: good quality drinking water made easily available 'low-tech', can be operated and maintained by local workforce provides income generation and work for local workforce to be applied in rural and remote situations low operational and maintenance costs proven technology More information is given here (pdf) and here for comprehensive pdf leaflet.
