A new test sheet developed in Spain reveals the presence of mercury in water (Photo: J. M....

Researchers at the University of Burgos in Spain have developed a portable and inexpensive new method of detecting levels of mercury in water. The simple test uses a sheet that changes color when inserted into mercury-contaminated water, with results visible to the naked eye.  Read More

UK-based Biobot has introduced a simple chemical reactor for converting used kitchen oils ...

One difficult aspect of a greener lifestyle involves disposal of used cooking fats. Most people either pour it down the drain, where it can lurk for years while conspiring to clog your pipes, or pour it in the yard, where it attracts pests of various sorts looking for a free meal. Recycling is obviously a better option, and to this end the BioBot 20 tabletop diesel processor – a (relatively) simple chemical reactor for converting used kitchen oils into biodiesel fuel at home – has been introduced by UK-based company Biobot.  Read More

The sea urchin has revealed a way to ceaply and quickly convert CO2 into calcium carbonate...

Carbon capture and sequestration in underground reservoirs isn’t the most practical or cost effective way to reduce atmospheric CO2 levels. It would be much simpler if CO2 could be quickly and cheaply converted into a harmless, solid mineral before it is released into the atmosphere. A team from the U.K.’s Newcastle University may have stumbled across a way to achieve this thanks to the humble sea urchin.  Read More

Researchers at FMTC reduced the power consumption of their badminton robot by 50 percent, ...

Eco-friendly refrigerators, dishwashers, and laundry machines don't just save you money – they're also better for the environment. Factory automation could reap the same rewards, but optimizing production lines isn't easy. That's where the energy efficiency analysis software, developed by the EU-funded Energy Software Tools for Sustainable Machine Design (ESTOMAD) project, enters the picture.  Read More

The new water-saving membranes developed at MSU (Photo: MSU)

With climate change predicted to increase the severity and frequency of drought events in many part of the world, water conservation is a growing concern. New water retention technology developed at Michigan State University (MSU) could help quench the thirst of parched crops while using less water, not only enabling crops to better deal with drought, but also improving crop yields in marginal areas.  Read More

The Oxijet nozzle

Low-flow shower heads are a good way to save water, but using one can be a bit like showering with a spray bottle. New Zealand company Felton, in collaboration with Australia's Commonwealth Scientific and Industrial Research Organisation (CSIRO), has developed the Oxijet – an “air shower” head that injects tiny air bubbles into the water droplets to make the shower feel like it’s at full pressure, yet while using 50 percent less water.  Read More

Canadian eco-enthusiast Dan Baker has converted a golf cart into an electric snow-blowing ...

Canadian eco-enthusiast Dan Baker is at it again, converting a golf cart into an electric snow-blowing machine. Last year Baker home built the Firefly solar-powered boat from scratch and this winter he’s determined not to be snowed in.  Read More

Swedish researchers believe that size is they key to furthering the development of nanowir...

In a breakthrough that could lead to more efficient and cheaper solar cells, scientists at Sweden's Lund University claim to have identified the ideal diameter for nanowires to convert sunlight into electricity.  Read More

The Short Circuit appliances should be available for purchase later this year

In recent years, repairing and upgrading electronics has largely given way to a trend of disposable gadgets which fill up landfills – especially with regard to home appliances like coffee makers and toasters. However, French designer Gaspard Tiné-Berès proposes to repair and re-use discarded and damaged appliances, with readily available reclaimed materials providing the necessary components, and the bodies constructed from cork.  Read More

New research could result in cheaper, more efficient thin solar cell production (Photo: Em...

Scientists based at Empa, the Swiss Federal Laboratories for Materials Science and Technology, have set a new efficiency record for thin-film copper indium gallium (di)selenid (or CIGS) based solar cells on flexible polymer foils, reaching an efficiency of 20.4 percent. This is an increase from a previous record of 18.7 percent set by the team back in 2011.  Read More
