Water

As water shortage is a serious issue in many parts of the world, a means of efficiently harnessing safe drinking water from thin air without the need of expensive infrastructure could be a real lifesaver. Italy's Architecture and Vision is developing an off-grid bamboo tower called Warka Water that promises just that: the firm says it could collect an annual average of up to 100 liters (26.4 US gallons) of water per day.

A Mexican startup Ak Inovex has developed a new method of recycling plastic that does away with water and only consumes half the energy of previous systems. At the same time, it produces plastic pellets of equal or better quality,  resulting in an environmentally friendlier process that also promises to be significantly cheaper. Read More
Drinking clean water is something that many people in the world can't take for granted, as they rely on polluted sources and often have no access to purification systems. In response to that problem, Panasonic is developing a new technology that looks to the sun to clean water extracted from the ground. The company recently presented a system that uses sunlight and photocatalysts to purify polluted water at a high reaction rate, to improve access to clean water where it's needed. Read More
We looked at 2014's coolest land toys earlier this month; now we leave the shore in our wake and head out to sea. The year in water toys kicked off in a big way at Boot Düsseldorf 2014 in January and it ran strong the year through. In fact, we'd say the past year saw reveals and market launches of some of the coolest water toys in recent history ... everything from transforming boats, to seven-figure personal submarines to underwater jet packs.

Desalination may one day prove the savior for regions of the world where clean drinking water is scarce, but current technology dictates that this process is often expensive and energy-intensive. The team behind the Desolenator has high hopes of delivering water security to those in need, with a mobile desalinator that runs purely on energy from the sun. Read More
Watching on as the waves crashed against the cliffs of South Corsica, France, mechanical engineer Dragan Tutić knew some were already drawing on power from the ocean to generate electricity. But a possible use for all that motion in the ocean that had been largely unexplored, as far as he knew, was turning its salty seawater into the fresh, drinkable variety on the spot. In the following two and a half years, Tutić and his team designed and tested a prototype for a wave-powered desalinator, and now hold hopes of deploying the system in regions where water scarcity threatens the survival of coastal communities.

When you're using helicopters to dump water on forest fires, it goes without saying that the faster you can obtain and deliver water from lakes or other sources, the better. Most currently-used systems are able to gather H2O at rates ranging from 1,700 to 4,000 liters (450 to 1,056 US gal) per minute, which is fairly impressive. A new system developed by Spanish firm Inventec, however, is claimed to be capable of sucking up 1,000 L (264 gal) in just five seconds – that scales up to a rate of 12,000 L (3,170 gal) per minute. What's more, it's also said to be safer. Read More
The oceans are a mystery in more ways than one, but you might not expect the answers to come from a pack of electronics and a comet. But that's what the European Space Agency (ESA) says about the unmanned Rosetta probe orbiting comet 67P/Churyumov–Gerasimenko. Though 67P is making its first visit to the inner Solar System and won't come closer to the Earth than hundreds of millions of miles, it is throwing new light on one of the fundamental questions in Earth's history: Where did the oceans come from?

When it comes to robots that perform internal inspections of water pipes, virtually all of them move along on rubber tires or treads. As that rubber grips against the inside of the pipe, however, it dislodges rust particles that ultimately end up coming out of peoples' taps. In an effort to address that problem, the European Union TRACT project is developing a propeller-driven inspection robot that keeps the pipe-touching to a minimum. Read More
The use of "ocean gliders" for conducting research in oceanic conditions not ideal for regular methods has been catching on in the scientific community. Examples of this have been seen in the detection of endangered whales in the North Atlantic and a study of the Atlantic sturgeon. Researchers have now turned their robotic ocean helpers towards Antarctica, to study the rapidly-melting ice sheets on the coast of the western part of that polar land mass. Read More
