Cross country skiing in the summer

Decades ago, a few individuals looked at what skiers were doing on snow and thought, "Why can't I do that on a board?" Thus, the sport of snowboarding was born, and it eventually exploded in popularity. On the water, the opposite is happening. The sport of paddleboarding has been growing in popularity and some folks are thinking, "Why can't I do that on skis?" With the Slovenian-designed ABH20 skis, you can. Strap a pair on and you can walk on water.  Read More

Amphiro's a1 self-powered water and energy meter puts water and energy consumption in the ...

There's nothing like putting real time water and energy usage information in your face to change people's shower habits, and that's just what Amphiro's a1 self-powered water and energy meter does. It connects between the shower hose and a handheld showerhead and, like the Driblet, generates the electricity required to power it from the flow of water running through it.  Read More

The HydroBee generates electricity using the current of a stream or river

There are already plenty of gadgets that allow people to charge their mobile devices while off the grid. Most of those products utilize solar power, while a few have gone the thermoelectric route. The HydroBee, however, generates electricity using the power of flowing water – think of it as a portable hydroelectric station.  Read More

This image shows two electrodes connected via an external voltage source splitting water i...

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
