Water Conservation

With climate change predicted to increase the severity and frequency of drought events in many part of the world, water conservation is a growing concern. New water retention technology developed at Michigan State University (MSU) could help quench the thirst of parched crops while using less water, not only enabling crops to better deal with drought, but also improving crop yields in marginal areas.  Read More

The Oxijet nozzle

Low-flow shower heads are a good way to save water, but using one can be a bit like showering with a spray bottle. New Zealand company Felton, in collaboration with Australia's Commonwealth Scientific and Industrial Research Organisation (CSIRO), has developed the Oxijet – an “air shower” head that injects tiny air bubbles into the water droplets to make the shower feel like it’s at full pressure, yet while using 50 percent less water.  Read More

Worldwide population growth and the related rapid increase in urbanization is already posing problems in many areas for the management of that most precious of resources, water. With these problems only set to intensify, the Organization for Economic Co-Operation and Development (OECD) has released a report outlining the challenges humanity faces to maintain water resources in the face of demographic growth and climate change. Called Meeting the Water Reform Challenge, the report says that urgent reform of water policies is crucial in order to preserve human and environmental health as well as economic growth.  Read More

A new process has been developed for removing trace amounts of heavy metals from water (Ph...

Once released into the environment from industrial sources, trace amounts of heavy metals can remain present in waterways for decades, or even centuries, in concentrations that are still high enough to pose a health risk. While processes do exist for removing larger amounts of heavy metals from water, these do not work on smaller quantities. Now, however, scientists from Rhode Island’s Brown University have combined two existing methods, to create a new one that removes even trace amounts of heavy metal from water.  Read More

Prof. Tim Leighton and Dr. Peter Birkin with their ultrasonic nozzle

In many industries, such as health care, food preparation and electronics manufacturing, cleanliness is of the utmost importance. It’s important enough that huge quantities of water are used – and left tainted – in order to remove contaminants. While some groups have concentrated on creating better cleansers, a team of scientists from the University of Southampton have taken a different approach. They’ve created an ultrasonic tap nozzle, that allows the water itself do a better job at cleaning. The better that a given amount of water is able to clean, the less of it that needs to be used.  Read More

Edward Linacre has won the 2011 James Dyson Award for his Airdrop irrigation concept

Young Melbourne-based inventor Edward Linacre has won the 2011 James Dyson Award, making it the second year in a row where the prestigious prize has gone to an Aussie. Linacre stole this year's competition with his Airdrop irrigation concept that collects water from thin air. The Swinburne University of Technology design graduate was driven to transform an ancient cooling technique into a new sub-surface irrigation system, following the enduring Australian drought that saw high levels of farmer suicide along Australia's Murray- Darling Basin.  Read More

The Base Camp System Integration Laboratory, or SIL, at Fort Devens, Massachusetts (Image:...

The U.S. Army has opened a System Integration Laboratory (SIL) at Fort Devens, Massachusetts, modeled after forward operating bases in Iraq and Afghanistan to test technologies aimed at creating more energy-efficient base camps. The various energy-efficient technologies being tested are expected to reduce base camp fuel requirements by 20 percent or more and water demand by up to 75 percent.  Read More

The Russell Hobbs washing machines offering a 12 minute cycle - 7kg white and graphite mod...

Doing the laundry probably isn’t high on anyone’s list of fun things to do, so anything that speeds up the chore, while also cutting down on the amount of water and energy used, is going to be welcome. A new washing machine from Russell Hobbs looks to accomplish all these goals with its “super rapid wash” cycle rinsing and spinning a load of lightly soiled clothes in a world record time of just 12 minutes as opposed to an average 90-minute wash cycle.  Read More

Cleaning up the Seine with Physalia

Concerned about our rising population having serious water supply issues in the not too distant future, Lilypad floating city designer Vincent Callebaut has come up with a floating amphibious garden that can clean our rivers as it travels the waterways of Europe. His proposed "audacious, avant-garde" Physalia project will be a self-sufficient, nomadic research vessel which can also host aqua-focused exhibitions and conferences.  Read More

Fraunhofer is working on technologies to address the world water shortage

The Fraunhofer research organization is concerned about the world’s fresh water supply. According to the statistics put forth by groups like the World Commission on Water for the 21st Century, that concern is justified – over 450 million people worldwide currently face severe water shortages, and as much as two thirds of the world’s population could be “water-stressed” by 2025. Likewise, a study by the UN has predicted that water is due to become more strategically important than petroleum; in other words, wars could be fought over it. In reaction to scenarios such as these, 14 of Franhofer’s research divisions have joined together to form the Fraunhofer Alliance SysWasser, with the aim of developing sustainable water system technologies. The group will be presenting six of these technologies at this week’s IFAT/Entsorga water trade fair in Munich. Here’s a quick look at each one.  Read More
