Northwest Hydraulic Consultants principal Darren Shepherd, using a tiny kayak to assess th...

When an architect is designing a building, they build a scale model to check how their design will work as an actual physical structure. What happens, however, when engineers are designing things that will have to be compatible with the currents in rivers ... things like dams, bridges, or pump stations? Well, that’s where water resources engineering firms like Northwest Hydraulic Consultants (NHC) come into the picture. Their work often includes building exact miniature recreations of waterways, complete with flowing water. We recently caught up with NHC principal Darren Shepherd, who guided us through the production process of one of his more exciting models – a one-twelfth scale Norwegian whitewater kayaking park.  Read More

The dispersants used to control the Deep Horizon oil spill were criticized for their toxic...

Some people believe that there’s no problem that peanut butter, chocolate and whipped cream can’t solve. These people could be onto something with news that a team of researchers has developed a new, safer oil dispersant that uses edible ingredients found in the aforementioned trio of treats. The new dispersant could save the lives of thousands of birds and animals caught in environmental catastrophes.  Read More

TOHL tests its pipeline-laying technique

A new startup named TOHL, comprised of a handful young Georgia Tech graduates, has set up shop in Chile in an effort to "change the way people think about pipelines." Using little more than a helicopter and a coil of flexible high-density polyethylene (HDPE) pipe, TOHL laid a kilometer (0.6 miles) of water pipeline by helicopter in a "record-setting" nine minutes, despite windy conditions and mountainous terrain. TOHL claims this is "the first ever completely aerial installation of a pipeline." Now company President Benjamin Cohen is taking to Kickstarter to ask for US$30,000 to build the company's first "full-scale" installation.  Read More

Researchers have developed a system that uses a pressure wave to reliably and rapidly loca...

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
