Researchers produce hydrogen from sunlight, water and rust

By - November 12, 2012 4 Pictures
As scientists endeavor to increase the efficiency of solar panels, the challenge of storing the resultant energy cheaply and in an environmentally responsible way must also be met. To this end, researchers at Switzerland’s École polytechnique fédérale de Lausann (EPFL) have developed an inexpensive device that transforms light energy into hydrogen, for storage and later use. The new prototype makes use of sunlight, water, and metal oxides, including iron oxide – or rust. Read More

Gravity probe shows groundwater reserves slipping away

By - September 25, 2012 7 Pictures
Recently, drought seems to be a fact of life. As the lead photograph poignantly illustrates, most of the U.S. has been struggling with serious levels of drought for the past several years. Worldwide, drought affected areas include Europe, India and Pakistan, Russia, much of Africa, South America – the list goes on. But when the rains start again, everyone expresses great relief, not realizing that long-term depletion of groundwater reserves is part of the price for surviving drought. It was with this in mind that GRACE (Gravity Recovery and Climate Experiment), a joint U.S. and German space project, was designed a decade ago. Read More

Washit cleans you and your clothes simultaneously

By - September 19, 2012 4 Pictures
Water is a precious resource and in places like Australia and the U.K., the onset of summer coincides with restrictions on water use – hosepipes for watering gardens are banned, and showers are recommended over baths. But even taking a shower uses a fair amount of water, which all ends up down the drain. The same goes for doing laundry. If only there was a way to combine the two into one unified unit. There is, or at least there could be in the future. Four university students in Turkey have collectively designed Washit, a concept shower and washing machine combo that's capable of cleaning you and your clothes simultaneously. Read More

Superhydrophobic coating allows water to boil without bubbles

By - September 14, 2012 1 Picture
You know that thing that water does when it boils? The thing with the bubbles? Turns out, it doesn't really need to do that at all, with scientists finding a way to make boiling water a completely bubble-free zone. Researchers from Northwestern University, King Abdullah University of Science and Technology in Saudi Arabia and Melbourne University in Australia teamed up to prevent water from bubbling when it boils by using tiny spheres coated with a hydrophobic material.

Solar-powered oven makes fresh water

By - September 9, 2012 8 Pictures
Sometimes the simplest ideas are the best. Concerned about the lack of fresh water in the developing world, designer Gabriele Diamanti wanted a solution to desalinate water that was available to households rather than relying on giant centralized plants. He also wanted it to be something inexpensive that could be made by local craftsman. The result is a ceramic solar still called the Eliodomestico that operates like an “upside-down coffee percolator”. Read More

Aqua Zinger bottle blends water to your taste

By - September 4, 2012 4 Pictures
We're constantly told to drink more liquids, with water especially recommended for re-hydrating thanks to its lack of any additives or diuretic qualities. But pure water, even the best mineral water money can buy, can be boring to drink all the time. Beverage manufacturers are aware of this with "flavored water" appearing on the shelves next to the regular stuff in recent times. The Aqua Zinger water bottle however, takes a DIY approach to spicing up your liquid intake by means of an attachable food blender. Read More

How to build a miniature Norwegian whitewater river

By - August 29, 2012 19 Pictures
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.

Edible dispersant could provide more eco-friendly way to fight oil spills

By - August 23, 2012 1 Picture
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: the startup that lays water pipelines by helicopter

By - August 22, 2012 5 Pictures
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
