A demonstration of how the phosphorus-laden particles can be removed from water using a ma...

Phosphorus is a mineral that's widely used in fertilizer, which itself has an unfortunate tendency to leach out of farmers' fields and into our waterways. Now, researchers from Germany's Fraunhofer Institute for Silicate Research have devised a method of retrieving some of that phosphorus from the water – thus both reducing pollution, and providing a source of reclaimed phosphorus.  Read More

Droplet works by selectively watering the plants in your garden

There's no two ways about it: your common or garden sprinkler (so garden, in all probability) is a blithering half-wit. Rain or no, if you don't turn it off, it'll water your lawn whether it needs it or not, and much more besides. The Droplet wants to change all that. A sort of "smart" water cannon, it knows which parts of your garden to water, and when.  Read More

In this false-color image, E. coli bacteria (green dots) can be seen trapped around pit me...

In many parts of the world, the presence of harmful bacteria makes it vitally important that water from lakes or rivers be thoroughly filtered before being consumed. While materials such as silver nanoparticles and titanium dioxide will do the job, people in developing nations or rural settings typically need something a lot cheaper and easier to manufacture. As it turns out, wood from pine trees works great.  Read More

NASA's Mars Reconnaissance Orbiter doing what it does best – orbiting Mars (Image: NASA)

NASA's Mars Reconnaissance Orbiter has transmitted further measurements of curious seasonal marks on the surface of Mars. They could be the most compelling evidence yet of flowing water existing on the Red Planet in the present day.  Read More

The WaterWheel is designed to transport three to five times as much water as traditional m...

Since landing in India in September of 2011, social venture Wello has carried out extensive research in an effort to improve the efficiency of water transport and storage in developing countries. For many people living in these areas the chore of walking long distances while carrying buckets of water is inefficient, dangerous and counter-productive. The team's work has culminated in what it believes could form part of a solution, a prototype for a pushable high-quality plastic container dubbed the WaterWheel.  Read More

Scientists in Australia have reported the discovery of huge freshwater reserves preserved in aquifers under the world's oceans. The water has remained shielded from seawater thanks to the accumulation of a protective layer of sediment and clay. And it’s not a local phenomenon. Such reserves are to be found under continental shelves off Australia, China, North America and South Africa.  Read More

Cross country skiing in the summer

Decades ago, a few individuals looked at what skiers were doing on snow and thought, "Why can't I do that on a board?" Thus, the sport of snowboarding was born, and it eventually exploded in popularity. On the water, the opposite is happening. The sport of paddleboarding has been growing in popularity and some folks are thinking, "Why can't I do that on skis?" With the Slovenian-designed ABH20 skis, you can. Strap a pair on and you can walk on water.  Read More

Amphiro's a1 self-powered water and energy meter puts water and energy consumption in the ...

There's nothing like putting real time water and energy usage information in your face to change people's shower habits, and that's just what Amphiro's a1 self-powered water and energy meter does. It connects between the shower hose and a handheld showerhead and, like the Driblet, generates the electricity required to power it from the flow of water running through it.  Read More

The HydroBee generates electricity using the current of a stream or river

There are already plenty of gadgets that allow people to charge their mobile devices while off the grid. Most of those products utilize solar power, while a few have gone the thermoelectric route. The HydroBee, however, generates electricity using the power of flowing water – think of it as a portable hydroelectric station.  Read More
