Water

Photoelectrochemical (PEC) cells can use sunlight to sustainably split water into hydrogen and oxygen, but efficient PEC materials tend to corrode rapidly in use. A Stanford research group has been studying this problem, and has found that depositing a thin layer of nickel atoms on a silicon PEC electrode allows it to operate for over 80 hours with no sign of corrosion.  Read More

The Zayak provides a look at fish, plants and other sea life

Looking like a cross between a raft and a massage table, the Zayak Sea Sled is a new snorkeling alternative. It opens up the same type of underwater views, only without the need to submerge your face and breathe through a tube. You can explore the sea without getting a single strand of hair wet.  Read More

SafeFlame technology converts water into hydrogen and oxygen gas

The pressurized acetylene and propane gas used in brazing and related tasks is highly flammable, and thus very dangerous. You know what isn't flammable, though? Water. Bearing that in mind, the European Union-funded SafeFlame consortium has developed a torch system that generates a flame using nothing but H2O and electricity.  Read More

Driblet is a self-powered Wi-Fi-enabled water meter

Here's a crowd-funding campaign that probably deserves to be doing better than it is. Driblet is a smart water meter that connects to a water pipe to track use. Best of all, once it's installed, you don't need to worry about it running out of energy.  Read More

The Immerse-A-Clean wand is said to be much more portable than existing 'bleach generators...

Janitors and other people who do large-scale cleaning certainly don't have an easy job. Among other things, they have to lug around heavy bottles of bleach or other cleansers, then risk the harmful effects of those products when using them. Texas-based GenEon Technologies, however, is now offering an alternative. The company's Immerse-A-Clean wand can reportedly turn regular tap water into an effective sanitizer, glass- and general-purpose cleaner, using nothing other than electricity and a non-toxic catalyst.  Read More

Doctoral student Vinay Pagay holds one of the chips

Whether you're growing wine grapes or mixing cement, there are some situations in which it's vitally important to monitor moisture content. Normally water sensors are used, although these can be both large and expensive. Now, however, a team from Cornell University has created a water-sensing silicon chip that's not only tiny, but is also reportedly "a hundred times more sensitive than current devices." What's more, the chips might be possible to mass-produce for just $5 a pop.  Read More

 2,000 shipping containers are planned to be transformed into water purifying stations

Joining forces with engineering firm Deka R&D, Coca-Cola has launched a project which will see the transformation of approximately 2,000 shipping containers into water purifying stations. Dubbed Ekocenter, the shipping container module has been designed to provide isolated and developing communities with facilities to produce safe drinking water, as well as access to wireless internet technology and solar powered charging.  Read More

Team Austria (Vienna University of Technology) has been announced the overall winner of Solar Decathlon 2013 after the closest competition in the history of the event. Second place went to University of Nevada Las Vegas, with the Czech Technical University achieving third place overall.  Read More

BayCycle's water-bike (Photo: BayCycle Project)

The BayCycle Project is fast gathering attention for its crowd-funding campaign to bring a fully-fledged water-bike to the masses. BayCycle has released a number of eye-catching videos, including one of project founder Judah Schiller crossing San Francisco Bay on one (which is apparently a first). The project appears to be using off-the-shelf kits from Italian outfit SBK-KIT, whose Shuttle Bike we first featured back in 2005.  Read More

Waterstudio's design for the Citadel

The Dutch are known for their ingenuity in taming it and using it to their advantage, but their systems for keeping water at bay are now being rethought by architect Koen Olthuis and his team at Waterstudio. While rising sea and river levels have inspired governments around the world to invest in better flood defenses, with the Citadel, Olthuis is embracing water-borne housing with particular vigor.  Read More
