PowerCube is deployed as a shipping container and morphs into a power stations, communicat...

It was seven years ago that Ecosphere Technologies revealed its first iteration of a self-contained relief unit to provide power, water and shelter to disaster-struck areas. The company has since been busy refining the system's form and function and now announces the completion of what it says to be the world's largest deployable solar power generator. Capable of generating 15 kW of electricity, PowerCube is transported as a standard shipping container and can morph into a shelter, water treatment plant and communications base all with a push of a button.  Read More

ROSI is a new water filtration system that is both mobile and can be solar- or wind-powere...

Water-borne bacteria and viruses can cause serious health problems, but many places in Africa do not have access to clean drinking water. Mdori, in Tanzania, is one of those places. In addition, its natural spring water is too high in salt and fluoride. The new ROSI water filtration system could change this.  Read More

The treatment process in progress, using chemicals naturally abundant in wastewater to cle...

Using wastewater to clean itself is the premise of new Australian technology that relies on the formation of compounds called hydrotalicites, and which results in less sludge than traditional water treatment with lime. In one test in Australia, the equivalent of 20 Olympic-sized swimming pools of wastewater were treated, with final sludge reductions of up to 90 percent.  Read More

To address the material weakness of traditional hydrants, Sigelakis chose to go with a sta...

The traditional fire hydrant, that innocuous little cast metal tube with a hat, is one of those everyday objects that is so commonplace most people tend to overlook them. For over 100 years this life saving device has changed little in terms of design or functionality, but now an ex-fire fighter hopes to change all that with his next generation Spartan fire hydrant.  Read More

Harvesting water out of thin air, might seem like a pipe dream, but the air-stable water droplet networks, currently being developed by Oak Ridge National Laboratory (ORNL) researchers could prove to be a step in the right direction. Created with the aid of a new technique, these water droplet networks could also potentially find use in membrane research and biological sensing applications.  Read More

One of the modified nanocellulose sponges soaks up oil (red) while repelling water (blue)

As the Deepwater Horizon incident showed us, oil spills can be huge environmental disasters. That said, there are also considerable challenges in dealing with the waste products generated by the forestry and agriculture industries. Now, scientists from Switzerland's Empa research group have come up with a method of addressing the one problem with the other – they've developed sponges made from cellulose waste, that can soak up 50 times their own weight in oil.  Read More

A water sample being added to a vial for testing, using one of the new pills

Wondering if it's safe to drink the water from your remote village's well? Typically, the only way of finding out involves sending a sample of that water off to a lab, or using testing agents that must be shipped in and kept on dry ice. Now, however, scientists from Canada's McMaster University have developed simple pills that can do the job – and they were inspired by breath-freshening strips.  Read More

Port X, by Czech architecture firm Atelier SAD (Photo: Port X)

Czech architecture firm Atelier SAD recently unveiled an interesting modular prefab home that can either be installed on the ground like a normal home, or float on the water like a (non-motorized) houseboat. Dubbed Port X, the unusual dwelling comes in several sizes, can be expanded upon to increase living space if needed, and operates either on or off-grid.  Read More

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
