New low-cost material could help bolster carbon capture

By - September 25, 2012 1 Picture
Researchers at the University of Nottingham have developed another weapon in the ongoing war to reduce the amount of greenhouse gases emitted from fossil fuel-burning power plants. The researchers have created a new porous material called NOTT-300 that they claim is cheaper and more efficient than existing materials at capturing polluting gases, such as carbon dioxide and sulfur dioxide, from flue gas.

Tiny new air samplers could aid in climate research

By - April 11, 2012 1 Picture
The monitoring of air quality can be a tricky business. Gases may be blown into the sampling site from another area, they may leak out of an air sample before it can be analyzed, or the sampling container itself may introduce compounds, emitted through off-gassing. If samples are being gathered in remote areas, it can also be difficult getting bulky equipment to and from the sampling site. Now, scientists from Sandia National Laboratories have announced a tiny new type of air sampler, that addresses these and other challenges. Read More

Study finds sunshade geoengineering could improve crop yields

By - January 26, 2012 1 Picture
In the face of potentially catastrophic effects on global food production, some have proposed drastic solutions to counteract climate change such as reflecting sunlight away from the Earth. A new study from the Carnegie Institution for Science examining the effects of sunshade geoengineering has concluded that such an approach would be more likely to improve food security than threaten it.

New study highlights the environmental benefits of lab-grown meat

By - July 18, 2011 1 Picture
As a meat lover, it's been hard not to notice the rise in the price of meat at my local supermarket over the last few years. But it’s not just the cost to consumers that is a major concern; it’s the major role that livestock production plays on climate change. While cultured meat, also known as in vitro meat, lab-grown meat and even Frankenmeat, might not sound that appetizing to many meat lovers, a new study carried out by scientists from Oxford University and the University of Amsterdam says that cultured meat would provide substantial environmental benefits.

Ark Angel LSV: Sauter's latest green megayacht gets speed injection

By - March 20, 2011 2 Pictures
Like its Super Nova and Ocean Empire LSV stablemates, the 78 meter (256 ft) Ark Angel LSV (Life Support Vessel) from Sauter Carbon Offset Design harnesses energy from a variety of renewable sources to achieve up to 100 percent reduction in fuel consumption and greenhouse gas emissions. When using its four 400 kW Daimler Bluetec Turbo Compound DD16 diesel engines, Sauter says that the green megayacht is capable of sailing at 28 knots while still reducing fuel consumption and emissions by 50 percent.

Tesla announces lithium-ion battery recycling program in Europe

By - February 1, 2011 2 Pictures
When weighing up the impact of electric-vehicles on the environment two factors come to the fore. EV's produce no emissions locally, but depending on where the energy comes from, they can still be producing greenhouse gases back at the power plant ... the so called "long-tailpipe" argument. That's one. The second is batteries – or more specifically, how much energy goes into making them and what to do with the massive battery packs in these cars once they've passed their lifespan. Auto manufacturers building EV infrastructure are taking this second factor into consideration and now EV pioneer Tesla has announced a battery recycling program throughout Europe that will help reduce the carbon footprint of its vehicles.

Oregon's 845 megawatt wind farm receives U.S. government support

By - October 13, 2010 1 Picture
A large scale wind farm to be built in central Oregon has received "a conditional commitment to provide a partial guarantee for a $1.3 billion loan" from the U.S. Department of Energy. Made up of 338 GE wind turbines, the Caithness Shepherds Flat 845 megawatt project will create 400 construction jobs (plus 35 permanent jobs once up and running) and promises a reduction in greenhouse gas emissions equivalent to that produced by more than 200,000 cars.

Super Nova – world’s first carbon neutral megayacht

By - August 15, 2010 3 Pictures
Looking to claim the environmental high ground at the next megayacht owners potluck get together? Sauter Carbon Offset Design has unveiled what it calls “the world’s first carbon neutral megayacht,” and it could be just what you’re looking for. Harnessing energy from sustainable sources such as photovoltaic (PV) cells, power sailing kinetic energy regeneration and wingsails, the Super Nova 60 is capable of generating enough surplus energy to allow it to cruise carbon neutral for 7,000 nautical miles a year... and it can feed energy back into the grid while docked. Now you can enjoy cruising around the Mediterranean in luxury with an environmentally clear conscience. Read More

Offsetting greenhouse gas emissions using charcoal

By - August 11, 2010 3 Pictures
According to a new study, as much as 12 percent of the world’s human-caused greenhouse gas emissions could be sustainably offset by producing biochar, a charcoal-like substance made from plants and other organic materials. That’s more than would be offset if the same plants and materials were burned to generate bioenergy, says the study. Additionally, biochar could improve food production in the world’s poorest regions as it increases soil fertility. Read More

Double bubble aircraft design would use 70 percent less fuel

By - May 19, 2010 2 Pictures
The contribution of aircraft to greenhouse gas emissions has been well documented and while biofuels are being trialled in an effort to combat the issue, an expected doubling in air traffic by 2035 suggests that a fundamental shift in technology is needed to make real progress. That's the starting point for the D “double bubble” – a design concept presented to NASA by an MIT led research team which promises a 70 percent improvement in fuel economy, reduced noise, lower nitrogen oxide (NOx) emissions and the ability to use shorter runways.
