Silicon/nickel water splitter could lead to cheaper hydrogen

By - November 18, 2013 2 Pictures
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.

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

Immerse-A-Clean wand creates a cleanser from tap water

By - October 23, 2013
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.

Tiny, cheap water-sensing chip outperforms larger, pricier sensors

By - October 18, 2013 2 Pictures
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

Shipping container conversion provides clean water in developing countries

By - October 16, 2013 10 Pictures
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.
