New inexpensive method to clean oil from water
By Darren Quick
19:46 November 17, 2009 PST

The rainbow effect caused by varying thicknesses of oil film on water’s surface might be pretty to look at but is indicative of polluted water. This “oil sheen” proves especially difficult to remove, even when the water is aerated with ozone or filtered through sand. But now a University of Utah engineer has developed an inexpensive new method to remove oil sheen by repeatedly pressurizing and depressurizing ozone gas, creating microscopic bubbles that attack the oil so it can be removed by sand filters.

‘Smart Trash’ cash for recycling concept
By Darren Quick
21:52 November 2, 2009 PST

If the benefit to our environment isn’t enough to get some people to recycle, Georgia Tech’s Valerie Thomas has come up with the concept of offering a cash incentive enabled by “Smart Trash”. The concept involves a scanner integrated into a trash receptacle that automatically records what is being disposed of using Universal Product Codes (UPC) or radio frequency identification (RFID) tags attached to the trash. This would not only allow recyclers to better sort the waste but could also provide a cash back channel to consumers recycling goods of value. Read More

Research highlights environmentally friendly nature of digital music distribution
By Paul Lester
15:25 October 12, 2009 PDT

Despite the music industry being relatively slow to catch on to the fact that accessing music online is clearly the way forwards, the phasing out of DRM and appearance of innovative new services that offer consumers more choice, convenience and easy access to tunes, suggests that things are finally falling into place. One area that is often omitted when discussing the pros and cons of online is the environment, and it stands to reason that there would be a noticeable impact when you remove the cost of both printing CDs and delivering them to the consumer.

Trashing existing fuel sources could cut global emissions by 80%
By Darren Quick
01:03 September 30, 2009 PDT

If there’s one thing there seems to be an endless supply of, it's garbage. The idea of turning the trash that currently ends up in landfill into a fuel to combat the growing energy crisis and tackle carbon emissions isn’t new. Companies like Waste2tricity in the UK are already looking to convert waste from business and industry into clean electricity. Now scientists in Singapore and Switzerland have added credence to the idea, saying that replacing gasoline with biofuel derived from processed waste biomass could cut global emissions by 80%.

Keeping supersonic transport quiet
By Paul Lester
20:54 August 4, 2009 PDT

Supersonic business jets have traditionally got a bad rap when it comes to practicality and the environment, with high costs, loud noises and short range far outweighing the benefits of speed. The future of air travel will therefore be subject to stringent criteria to ensure that economy and eco-credentials, particularly noise pollution, don’t take a back seat to comfort and performance, and with this in mind Supersonic Aerospace International seem to have hit a luxury-class balance between the two.

Capturing more heat from low-temp resources to aid geothermal power
By Darren Quick
01:29 July 20, 2009 PDT

Geothermal power is cost effective, reliable, and environmentally friendly, but it has previously been limited to geographic areas near tectonic plate boundaries. New technologies, such as that employed in the Raser low-temperature binary geothermal plant, promise to expand the opportunities for geothermal plants. Now scientists at the Department of Energy's Pacific Northwest National Laboratory (PNNL) have devised a method for capturing significantly more heat from low-temperature geothermal resources to further boost the possibility of virtually pollution-free electricity.

Further doubts atmospheric umbrella will save marine environments
By Darren Quick
15:55 June 18, 2009 PDT

We recently looked at problems with a last resort solution to counteract global warming by artificially shading the Earth from sunlight by injecting sulphur or small, reflective particles into the upper atmosphere. Now a new study from the Carnegie Institution has thrown further doubt on the effectiveness of such a proposal. Although it may lower the planet’s temperature by a couple of degrees, it would do little to stop the acidification of the world’s oceans that threatens coral reefs and other marine life. Read More

GE and NASA to give open-rotor jet engine systems a spin
By Jude Garvey
06:31 June 15, 2009 PDT

GE Aviation and NASA will run a wind tunnel test program over the northern summer to evaluate and test counter-rotating fan-blade systems for open-rotor jet engine designs. The newly improved rig for testing was originally used by GE and NASA in the 1980s on scale models of counter-rotating fan systems, which led to the development of the GE36 engine. The test program also demonstrated that an open-rotor jet engine consumed 30 percent less fuel compared to similar-sized conventional jet engines. Just think what a 30 percent drop in fuel consumption would deliver today, not only to an airline industry struggling to keep ticket prices down, but also the positive benefits to the environment.

Study exposes transport's hidden impact on the environment
By Darren Quick
02:29 June 15, 2009 PDT

By looking at the environmental impact of passenger transport – whether it be trains, planes or automobiles – beyond the exhaust fumes spewing from its collective tail pipe, researchers in the United States have discovered a significant spike in energy use and greenhouse gas emissions. By taking into account transport support systems – which includes sourcing raw materials, manufacturing, as well as the construction and maintenance of infrastructure – researchers at the University of California hope to provide a more detailed view for transport planners and policy makers. And produce a better outcome for the environment. Read More

Playing roulette with the climate – everybody loses
By Darren Quick
07:55 May 22, 2009 PDT

Research carried out by the MIT's Center for Global Change Science has predicted that global warming will be roughly double previous estimates – and could be even worse than that. While a major 2003 study indicated a median projected increase in earth surface warming of 2.4 degrees Celsius, the new study, which takes into account possible changes in human activities, points to a median probability of surface warming of 5.2 degrees Celsius by 2100 unless drastic action is taken.
