Water pipe-inspection robot designed to have a light touch

By - December 2, 2014 1 Picture
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

Ocean gliding robots used to study melting Antarctic sheet ice

By - November 17, 2014 2 Pictures
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

Silicon Valley's latest high-tech gadgetry makes sewage water drinkable

By - October 23, 2014 4 Pictures
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.

Cigarette ash may find use filtering arsenic from water

By - October 16, 2014 1 Picture
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

Low-cost water purifiers use chip packets to kill off dangerous bacteria

By - September 16, 2014 3 Pictures
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

Air HES system to collect water and generate electricity from the clouds

By - August 27, 2014 7 Pictures
Using a tethered airship floating high up amongst the clouds, the Air HES concept claims to yield both clean water and electricity by harvesting and condensing water vapor which it uses to spin up an electric turbine generator to create power. According to the creators, they have built a prototype to test their theory and have also conducted feasibility studies into upping the scale of their device to produce economically viable levels of water and power.

Switzerland's new natural swimming pool does away with the chemicals

By - August 19, 2014 10 Pictures
A whiff of chlorine is virtually synonymous with taking a dip in a swimming pool. While it helps to kill off bacteria, it also serves as a subtle reminder that you are wading around in chemically treated water (if tasting the odd mouthful just isn't enough). Switzerland's Naturbad Riehen swimming pool is entirely chemical-free, relying instead on a biological filter system to provide clean and natural water for thousands of patrons, no itchy red eyes in sight.

Scientists create a "water tractor beam"

By - August 10, 2014 1 Picture
If you've ever tried to retrieve an object that's floating away in a lake or the ocean, then you'll know how frustrating it can be, trying to draw that item towards you. According to research recently conducted at The Australian National University (ANU), however, it's possible to move such objects in whichever direction you wish – as long as you can generate the right type of waves.
