It's no secret that hundreds of millions of people around the world have little or no access to drinkable water. While a number of projects are aimed at getting filtration systems to those people, many of those systems require electricity, contain costly materials such as silver, or treat the water at a slow rate. The low-cost DrinkPure filter, by contrast, is simply screwed onto the top of an existing bottle, and can purify approximately one liter (34 fl oz) of water per minute. Read More

Making a water bomb (or water balloon) can be a laborious and time-consuming process. Unless you have Bunch O Balloons, a system for filling 100 balloons with water in under a minute. Read More

The urban heat island effect, whereby the high concentration of heat-retaining concrete and bitumen causes metropolitan centers to be significantly warmer than the rural areas surrounding them, is a common problem around the world. The phenomenon is particularly prevalent in Tokyo, Japan, but among the sea of towering structures stands one beacon of hope. The BioSkin that coats the NBF Osaki Building integrates evaporative cooling to keep its surface temperature down and could inspire new solutions to rising city temperatures across the globe.

Learning from Australia’s arid climate and recent struggles with drought, the Aussietank was developed to aid households in times of dry periods and water restrictions. The collapsible and portable water tank comes flat-packed in three different sizes and has recently become available to the USA market. It could help households hit by the North American drought to harvest water without the expense of permanent water tank installation. Read More
Generally-speaking, when there's something that we're trying to conserve, we don't just put it down the drain. For those of us who are trying to save power, however, that's just what happens when we let hot water from our showers or baths run straight into the sewer. The EcoDrain is made to address that problem, via a unique design that allows outgoing hot water to warm up incoming cold water. Read More
In an increasingly busy and relentless world where information is flowing all around us, it's more important than ever to switch off once in a while. There are many ways to relax, but floating in water is one of the best ways of completely and utterly drifting away. Which is where Float – designed to make floating in water a more pleasurable experience – could prove useful. Read More
Even under some form of supervision, young ones can and do drown in swimming pools and lakes. The iSwimband wearable sensor is designed to minimize these dangers by triggering an alarm on a paired iOS device when submerged for a dangerous length of time. Read More
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.

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
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
