The Desolenator produces clean drinking water using sunlight

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

The Odyssée system uses wave power to churn out clean drinking water

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.  Read More

Inventec's system is claimed to be faster and safer than existing helicopter-based water-d...

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 latest findings indicate that the Earth's water may not have come from comets (Image E...

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?  Read More

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

Oceanographers run through a series of tests in preparation to deploy one of the ocean gli...

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

The Brigadier is dust and shock proof

Lately, smartphones are growing larger, lighter and thinner, making them increasingly frail to the point where we might have to worry about a $1,000 iPhone 6 Plus warping or bending in a back pocket. Amid this strange new status quo, the Kyocera Brigadier is the increasingly rare phone that need not be handled with care.  Read More

If California’s drought continues, residents may be drinking the recycled water from the S...

Drinking recycled urine may be the stuff of Dune novels, and a drastic response to California’s ongoing drought. But officials in Santa Clara County in the heart of Silicon Valley are hoping its new high-tech purification plant will help residents get past the ick factor and eventually allow treated wastewater to flow through their faucets in a "toilet to tap" scenario. Opened in July, the $72 million Silicon Valley Advanced Water Purification Center is the most advanced such plant in the US, and uses a multi-step system of microfiltration, reverse osmosis and ultraviolet rays to produce water of higher quality than typical drinking water.  Read More

Cigarette ash could now have another use besides ... well, nothing (Photo: Shutterstock)

In a perfect world, cigarette waste simply wouldn't exist. Given that it does, though, scientists have explored a number of methods of repurposing it – these have included using compounds from cigarette butts to store energy, make shipping pallets, and rust-proof steel. Now, researchers have shown that cigarette ash can be used as a low-cost means of filtering arsenic from water supplies. It's a little ironic, as cigarette smoke actually contains a dangerous amount of arsenic.  Read More

The water runs through a piece of piping, which rests in a trench-shaped structure coated ...

Armed with plywood, a glass tube and some empty chip packets, mechanical engineering students from the University of Adelaide have developed a low-cost water purification system capable of killing off harmful bacteria. The solution is designed for remote communities in Papua New Guinea (PNG), an area where water is particularly susceptible to pathogen infestation.  Read More
