Researchers at Australia's CSIRO have claimed a world record for the highest temperatures ever achieved using solar energy to generate "supercritical" steam at its solar thermal test plant in Newcastle, Australia. Featuring more than 600 directional mirrors (heliostats) directed at two towers housing solar receivers and turbines, the researchers produced the steam at a pressure of 23.5 MPa (3400 psi) and 570° C (1,058° F).  Read More

Original Unverpackt is aiming to become Germany's first waste-free supermarket

When it comes to sustainability, you might know Germany best for its renewable energy ambitions and efforts to reduce carbon pollution. While these initiatives have been largely driven by government and researchers, a team of budding entrepreneurs is looking to get in on the action, too. Aiming to open this (northern summer), Original Unverpackt will be Germany's first package-free supermarket.  Read More

RemScan puts a self-contained soil analyzer in your hand (Photo: ZilteK)

Contamination of soil from petroleum spills is an ongoing problem that threatens to adversely affect the environment and the health of the people in it, so rapid testing of sites is a pressing issue. However, with laboratory samples and results requiring at least a number of days turn around, particularly in remote locations, rapid analysis is not usually possible. RemScan is a self-contained, hand-held hydrocarbon contamination testing device designed to address this problem. Recently released on the US market, the device is capable of testing many hundred samples a day, providing data on the spot, within seconds, and completely without the need of a laboratory.  Read More

Toshiba's factory will be isolated from the outside air and have tightly controlled air an...

Looking to take a bite out of the Japanese food market, electronics giant Toshiba has announced plans to construct a vegetable production factory in the city of Yokosuka. The factory will use tightly controlled air and lighting systems to optimize conditions for pesticide-free, indoor plant growth.  Read More

An analysis of data from the European Space Agency's (ESA) CryoSat satellite shows that ice loss in the Antarctic is increasing at an exponential rate. It is estimated that the polar region now loses 159 billion tonnes of ice each year, with the worst instances of degradation located in the Western area of the Amundsen Sea.  Read More

The pollution-fighting poem on display at the University of Sheffield

Air pollution is a problem in many of the world’s major cities and removing it requires 24/7 solutions, as well as a bit of imagination. Taking a literary run at the task, the University of Sheffield has revealed what it calls the “world’s first air-cleansing poem,” which is a combination of a new work by award-winning writer Simon Armitage and a chemical formula developed at Sheffield by Professor Tony Ryan. The hope is that it will not only raise awareness of air pollution, but also help persuade British industry to adopt the air-cleansing technology more widely.  Read More

Seatower: bringing down the cost of offshore wind farming

Offshore wind farming combines the clean, green, environmentally neutral benefits of land-based wind turbines, while being a lot less visually intrusive ... and restricting the usual NIMBY opposition to crustaceans and invertebrates. It's currently a lot more expensive to install turbines out at sea, though, and that's restricting the sector's development. Which is why the Seatower Cranefree turbine platform could be such a significant step forward. Cheaper and easier to install, and requiring less gargantuan and specialized equipment than standard monopile foundations, the Seatower base could help offshore wind farms reach profitability a lot quicker.  Read More

One of the modified nanocellulose sponges soaks up oil (red) while repelling water (blue)

As the Deepwater Horizon incident showed us, oil spills can be huge environmental disasters. That said, there are also considerable challenges in dealing with the waste products generated by the forestry and agriculture industries. Now, scientists from Switzerland's Empa research group have come up with a method of addressing the one problem with the other – they've developed sponges made from cellulose waste, that can soak up 50 times their own weight in oil.  Read More

UTEC's billboard filters 100,000 cubic meters of air every day, benefiting residents in a ...

Billboards could do more than just advertise, if scientists at the University of Engineering and Technology (UTEC) in Peru have their way. While UTEC's earlier billboard produced drinkable water, its latest creation scrubs the air free of pollutants. According to the team, a single billboard can do the work of 1,200 trees, purifying 100,000 cubic meters (3.5 million cubic feet) of air daily in crowded cities.  Read More

The solar reactor that was used to turn water and CO2 into jet fuel

In a move that could help address our insatiable thirst for fuel while at the same time help cut CO2 emissions, scientists with the SOLAR-JET (Solar chemical reactor demonstration and Optimization for Long-term Availability of Renewable Jet fuel) project have recently shown that through a multi-step process, concentrated sunlight can be used to convert carbon dioxide into kerosene, which can then be used as jet fuel.  Read More
