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

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

With its rubberized dial, the 999Bottle tracks your impact

We all know that using a stainless steel or polycarbonate water bottle is much more eco than using (and tossing) a disposable water bottle. It's kind of the trendy thing right now. But do you really know just how much garbage and energy that you're saving the Earth from? With the 999Bottle, it's easy to find out.  Read More

Eolewater's WMS1000 wind-driven water-harvesting system uses on-board cooling units to chi...

We've all seen ice cold glasses and bottles dripping with condensation after cooling water vapor in the air, and though grabbing water out of thin air is not new, it took French inventor and Eolewater founder Marc Parent's umpteenth emptying of his air conditioner's condensate to envision harvesting atmospheric moisture on a commercial scale using wind turbines. After years of designs and prototypes, his proof-of-concept device, essentially a wind-powered refrigeration/condensation/filtration unit, was put in operation in the dry desert air of Abu Dhabi last October where it's been reliably extracting 130-200 gal (approx. 500-800L) of clean, fresh water a day ever since.  Read More

A (wonderfully named) Salinity Sampler Sequencer 'plays' hourly river water samples with t...

After three years in development, Flow (or strictly speaking ~Flow, with a leading tilde), a floating musical watermill has opened to visitors at Newcastle Quayside in England's North East. Actually a tide mill, Flow's waterwheel powers a variety of handcrafted electroacoustic instruments. The sound of the instruments changes dynamically according to the conditions of the river itself. In a sense, the river is playing the mill.  Read More

NASA's stunning Perpetual Ocean animation visualizes ocean currents (Image: NASA/Goddard S...

NASA’s Goddard Space Flight Center is an unlikely entrant in the SIGGRAPH Computer Animation Festival. Its “Perpetual World” animation may have failed to appeal to the judging committee of the 2011 edition of the competition, but it sure succeeded in catching our eye. The jaw-dropping animation visualizes the flow of surface ocean currents around the world. The raw data regarding the currents from June 2005 through to December 2007 has been turned into a work of art reminiscent of van Gogh.  Read More

What’s the best way to plug a giant hole? Why with a giant plug, of course. That’s the thinking of the Department of Homeland Security’s (DHS) Science and Technology Directorate (S&T), which has created just such a giant plug to contain flooding or dangerous gases in mass transit tunnels. Measuring roughly 32 feet (9.7 m) long and with a diameter of 16 feet (4.9 m), the giant plug is an enormous inflatable cylinder that can be filled with air or water in minutes to quickly seal off a section of tunnel in the event of an accident, natural disaster or terrorist attack.  Read More
