Grasscrete: Sustainable Urban Drainage Product
December 9, 2007 09:34 AM - Lexington Blood, Triple Pundit

Grasscrete, the green alternative to standard concrete surfaces for parking lots, driveways, and access roads for vehicles or fire trucks. The benefit to Grasscrete for businesses and developers is that it drains at about the same rate as would an ordinary lawn in the same location. The presence of concrete has little effect on the drainage; the soil and the slope are the controlling factors which makes it beneficial for erosion control as well.

EU may go easier on CO2 curbs for big cars: paper
December 8, 2007 10:29 AM - Reuters

FRANKFURT (Reuters) - The European Commission may shift the burden of cutting average carbon dioxide (CO2) emissions more onto small cars than heavier and more powerful models, the Frankfurter Allgemeine Zeitung reported.

The paper, which quoted an internal EU paper, said on Saturday the Commission was requiring manufacturers of the smaller models to cut CO2 emissions at a higher rate in order for the bloc to achieve its average target by 2012.

PETA boycotting Mars candy co. over animal cruelty
December 7, 2007 09:25 PM - Reuters

WASHINGTON (Reuters) - People for the Ethical Treatment of Animals (PETA) is calling for a boycott of M&Ms, Twix candy bars and other snack foods made by Mars Inc, claiming the company funds experiments that kill mice, rats, guinea pigs and rabbits.

"In violation of its own written policy, the candy company is currently funding a study at the University of California, San Francisco, that uses rats. The rats are force fed by having plastic tubes shoved down their throats, and they are then cut open and killed," PETA said in a statement.

Football field-sized kite powers latest heavy freight ship
December 7, 2007 09:12 AM -

A kite the size of a football field will provide most of the power for a German heavy freight ship set to launch in December.

The Beluga shipping company that owns the 140-metre 'Beluga' said it expects the kites to decrease fuel consumption by up to 50 percent in optimal cases as well as a cutback of the emission of greenhouse gases on sea by 10 to 20 percent. Interestingly, the ship will be hauling windmills from Esbjerg, Denmark to Houston, Texas.

The company that makes the kite for the German transport, SkySails, has made kites for large yachts but is targeting commercial ships with new, larger kites. And it has the ambitious goal of equipping 1,500 ships with kites by 2015.

'Hellish' Hot Springs Yield Greenhouse Gas-eating Bug
December 7, 2007 08:54 AM - University of Calgary

A new species of bacteria discovered living in one of the most extreme environments on Earth could yield a tool in the fight against global warming.

In a paper published on Dec. 6 in the prestigious science journal Nature, U of C biology professor Peter Dunfield and colleagues describe the methane-eating microorganism they found in the geothermal field known as Hell’s Gate, near the city of Rotorua in New Zealand. It is the hardiest “methanotrophic” bacterium yet discovered, which makes it a likely candidate for use in reducing methane gas emissions from landfills, mines, industrial wastes, geothermal power plants and other sources.

Scientists find what makes the solar wind howl
December 6, 2007 05:09 PM - Reuters

WASHINGTON (Reuters) - The solar wind, which whips off the sun and blows past Earth and through the solar system, is unleashed by powerful magnetic waves in electrically charged gas around the sun, scientists said on Thursday.

The mechanisms that cause the solar wind had baffled scientists for decades, but were revealed in observations by a Japanese satellite called Hinode orbiting Earth, the scientists said in research published in the journal Science.

"The magnificent thing about the success of Hinode is its unprecedented view of the dynamics of the sun," Jonathan Cirtain, a solar physicist at NASA's Marshall Space Flight Center, Huntsville, Alabama, who helped in the research, said in a telephone interview.
