The Jerrycan offers 18.5 liters (4.9 gallons) of water-purifying and carrying capacity

The LIFESAVER Jerrycan is a large water purification jug that could be of great use to everyone from campers to inhabitants of remote villages. The Jerrycan incorporates a built-in filtration system which can purify 18.5 liters (4.9 gallons) of water at a time, along with an integrated shower attachment that lets you use the water for cleaning as well as drinking.  Read More

A prototype water heater system that uses cold water to make hot water pictured with Slate...

Apart from heating and cooling the house, water heating is one of the biggest energy drains in the average home. But what if you could literally use cold water to create hot water? That’s just what San Diego inventor Hal Slater claims to have done with the creation of a water heater system that promises to improve water heating efficiency by as much as 50 to 100 percent.  Read More

Refrigerators have gotten some handy upgrades in recent years, with everything from Wi-Fi enabled touchscreens to blast chillers for quickly cooling a beer. Now, Samsung has partnered with SodaStream to introduce the RF31FMESBSR Four-Door Refrigerator, which comes with a built-in sparkling water dispenser for making homemade soda.  Read More

PureMadi project leaders James Smith and Dr. Rebecca Dillingham

Silver is known for its antibacterial qualities, and has thus found its way into water filters created at institutions such as Stanford and McGill universities. Given that these filters are often used in developing nations, however, it would be nice if they could also contribute to the local economy – instead of being just one more thing that’s brought in from outside. Well, that’s just the idea behind the University of Virginia’s PureMadi filters and MadiDrops.  Read More

In arid places where fog occurs overnight, some people utilize so-called “fog harvesters” to acquire fresh water. These are typically pieces of netting that collect fog droplets, which then roll down into a container below. Various researchers have tried to increase the efficiency of these harvesters, such as by making them from a combination of hydrophilic (water-absorbing) and hydrophobic (water-repelling) materials. Now, a team of scientists have done something a little different – they’ve created a cotton-based fog-harvesting material that switches between being entirely hydrophilic and entirely hydrophobic.  Read More

Removing radioactive material from contaminated water, such as that in Japan’s Fukushima nuclear power plants, could be getting a little easier. Scientists from Houston’s Rice University and Lomonosov Moscow State University have discovered that when flakes of graphene oxide are added to such water, it causes the radionuclides to condense into clumps. Those clumps can then be separated and disposed of.  Read More

The regeneration of Cermak Road includes new sidewalks with permanent wind/solar powered p...

A streetscape that includes natural landscaping, bicycle lanes, wind powered lighting, storm water diversion for irrigation, drought-resistant native plants and innovative “smog-eating” concrete has earned Cermak road in Chicago the title of “greenest Street in America” according to the Chicago Department of Transport (CDOT). Opened in October 2012, the first phase two mile stretch is part of the Blue Island/Cermak Sustainable Streetscape project which was introduced in 2009 with the aim of reducing overall energy usage by 42 percent.  Read More

For most of us, chances are that we will never be in a car that plunges into the water. However, if you consider yourself “at risk” for that sort of eventuality – say, if you’re a rally driver or Jason Bourne – you might be interested in the Escape Belt. It automatically releases your seat belt when exposed to water.  Read More

The MESSENGER spacecraft has made a compelling case for the presence of water in the form of ice on the surface of the Solar System's smallest and innermost planet, Mercury. The case is supported by three independent groups of evidence from different sensors aboard the Mercury orbiter.  Read More
