Tracking down the source of a leak in water pipes can be a tricky business. Current techniques rely on acoustic sensing with microphones often used to identify noise resulting from pressurized water escaping the pipe. In plastic pipes in particular, that noise can fall away quickly, making leak detection difficult and time consuming. Researchers at the University of Sheffield claim to have developed a much more accurate system that locates leaks by sending a pressure wave along the pipe that sends back a signal if it passes any anomalies in the pipe’s surface.  Read More

adidas produced 50,000 t-shirts using the resourse-saving DryDye process in Q2 2012

Textiles are a resource-heavy business. In an effort to reduce water consumption, energy use and a need for chemicals, adidas created the DryDye technology, which uses pressurized CO2 in place of water to dye t-shirts and other garments.  Read More

The Solar Bag can be carried like a satchel for easier transport and will begin to purify ...

Lack of access to clean water causes the deaths of millions of people worldwide and in regions such as sub-Saharan Africa, clean water can be several days walk away. Producing a simple and cheap method of purifying water which doesn’t rely on first-world amenities such as a steady electricity supply, or batteries, has proven a significant challenge thus far, but a new prototype device created by Ryan Lynch and Marcus Triest offers hope of doing just this, for an estimated cost of around US$5.  Read More

The BYPASSER system is designed to minimize wasted water, by only dispensing water that's ...

What do you do when you want hot or cold water from the faucet? You set the temperature, turn the tap on, then wait for the water to reach the desired temperature before using any. Chances are, though, you simply let that initial not-hot-or-cold-enough water go down the drain. The new BYPASSER system from Belgium’s W&E Savings has been designed to keep that water from being wasted.  Read More

GE's AquaSel system reduced the waste stream to almost zero at a bottling plant in Asia

Although water is the world’s most precious commodity, an astounding amount of it is wasted by industries. Fortunately, water treatment and recovery has become the focus of several technology companies, including GE, which recently demonstrated a water treatment technology that virtually eliminates losses at bottling plants and other water-related operations. The pilot study of GE’s AquaSel, a non-thermal brine concentrator technology, took place at the plant of a leading beverage company in Asia. GE says costs were greatly reduced and there was almost no liquid discharge.  Read More

A free-surface simulation of the forces experienced when diving helped in the design of Sp...

A controversy during the 2008 Beijing Summer Olympics was Speedo's introduction of its drag reducing LZR Racer swimming outfit. The suit worked so well that it was subsequently outlawed by the Fédération Internationale de Natation (FINA) as the technological equivalent of doping - it gave too large an advantage. Now, with the help of ANSYS simulation software, and just in time for the 2012 London Summer Olympics, Speedo has introduced the Fastskin3 racing system, which offers a new and apparently legal approach to drag reduction during competitive swimming.  Read More

The WaterWear pack allows those in developing countries to more easily transport water

For most of us, access to clean water is just a turn of the tap away, but in many developing countries women and children are often tasked with fetching water and carrying it considerable distances in containers - often on their heads. Aside from the strain this places on the neck and back, these containers can be discarded jerry cans and buckets that originally carried fuel, oils, pesticides, paints and other chemicals that you wouldn’t want mixed with your drinking water. The WaterWear is a collapsible backpack designed to overcome these problems.  Read More

The HeatSeeker is a cooling mister that replaces the existing hose port cap on a fire truc...

Firefighters face many dangers, including burns, smoke inhalation and structure collapses. Because they're required to wear all that heavy gear while performing strenuous activities, however, they also risk heat stroke. That’s why firefighter Michael Robinson invented the HeatSeeker – a device that attaches to a fire truck’s existing hose port, creating a cooling mist.  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

New paper strips detect Escherichia coli simply, cheaply and quickly

Nothing can put a dampener on a summer holiday like a coliform bacteria outbreak. But even worse than being told to keep out of the water in the event of an outbreak is not being told to keep out of the water in the event of an outbreak and ending up paying the price. Researchers at McMaster University have now developed a paper strip test that is cheap to produce, extremely portable, simple to use, and detects E. coli in water in 30 minutes.  Read More
