The BYPASSER system is designed to minimize wasted water, by only dispensing water that's ...

What do you do when you want hot or cold water from the faucet? You set the temperature, turn the tap on, then wait for the water to reach the desired temperature before using any. Chances are, though, you simply let that initial not-hot-or-cold-enough water go down the drain. The new BYPASSER system from Belgium’s W&E Savings has been designed to keep that water from being wasted.  Read More

A sapphire disk etched in platinum could preserve information for future generations to de...

Storing data for longer than a few years is tricky enough with rapidly advancing technology, so what are you supposed to do if you need to store data for thousands or even millions of years? That's just the problem facing nuclear waste management companies, who need a way to warn future civilizations of hazardous sites that will withstand the test of time. Luckily a recent proposal may have the solution with a sapphire disk etched in platinum that could survive longer than humanity itself.  Read More

The Fuel Nozzle Drip Retainer is said to virtually eliminate the wasted drops of fuel that...

For most of us, it’s simply one of life’s little annoyances ... those last few drops of fuel that dribble out of the nozzle at the gas station. For the guys at Canada’s Dram Innovations, however, that run-on is a serious problem – and one that they’re addressing, with their Fuel Nozzle Drip Retainer.  Read More

Getting people to clean up after their dogs in public places is never easy - just take a look at how many "land mines" are dotted around your nearest park. One internet company in Mexico however, has hit on a clever incentive to encourage people to scoop up after their pet. Dog walkers in Mexico City are now finding pet waste disposal bins showing up in some parks that activate a free wireless network for a set amount of time depending on the size of the "deposit."  Read More

KeepCup, which claims to be “the world’s first barista standard reusable coffee cup,” has arrived on the shores of Italy, bringing to 32 the number of countries where the cup is now available. Developed in 2009 in response to the large global waste generated from disposable coffee cups, KeepCup attempts to blend the best elements of disposable and reusable cups.  Read More

Scientists have created a rechargeable battery using the lignin from pulp and paper mills

Scientists have discovered that lignin, a plentiful byproduct of the pulp and paper industry, can be used to store an electrical charge. They've used the material to create a prototype lignin-based rechargeable battery, and suggest that it could one day be used as a less expensive, safer alternative to the precious metals currently utilized in battery cathodes.  Read More

The pilot plant in Stuttgart that makes biogas out of waste from wholesale markets (Photo:...

Some readers might remember the Mr. Fusion unit in Back to the Future that Doc Brown fills with household garbage, including a banana peel and some beer, to power the iconic time-traveling DeLorean. While we're still some way from such direct means of running our cars on table scraps, researchers at Fraunhofer have developed a pilot plant that ferments the waste from wholesale fruit and veg markets, cafeterias and canteens to make methane, which can be used to power vehicles.  Read More

The upper outside walls of the McGee house are made from over 100 salvaged car roofs

While the McGee house may look like any other new designer home in the neighborhood, its walls tell a different story. Designed by husband and wife team Karl Wanaselja and Cate Leger of Leger Wanaselja Architecture, the upper outside walls of the house are made from over 100 salvaged car roofs. In a pursuit to build a house that utilized green technologies and reused materials, the couple sourced car roofs from a selection of gray-colored cars that had been left for parts in local junk yards in Berkeley, California. Their biggest challenge was sourcing car scraps that were in relatively good condition, without dents and with a good paint finish. The scraps were then cut into long tile-like shapes and used to complete the upper outside walls of the house, rendering a similar appearance to slate.  Read More

The Philips bio-light is 'powered' by glowing bioluminescent bacteria

The search for greener, more power-efficient lighting systems won't stop with compact fluorescents and LED systems if Dutch electronics giant Philips has anything to say about it. In an effort to embrace a truly natural approach to lighting, the company took a cue from fireflies and deep-sea creatures to create a (literally) green light powered not by electricity or sunlight, but by glowing bioluminescent bacteria.  Read More

Nuclear power plants are located close to sources of water, which is used as a coolant to handle the waste heat discharged by the plants. This means that water contaminated with radioactive material is often one of the problems to arise after a nuclear disaster. Researchers at Australia's Queensland University of Technology (QUT) have now developed what they say is a world-first intelligent absorbent that is capable of removing radioactive material from large amounts of contaminated water, resulting in clean water and concentrated waste that can be stored more efficiently.  Read More
