LONDON (Reuters) - Luxury carmaker Porsche may legally challenge London mayor Ken Livingstone's decision to tax gas guzzling cars driving in the city centre to help fight global warming. Porsche said on Tuesday the 25 pound ($48.74) daily charge was unfair, would not cut emissions of climate warming carbon dioxide and would deter businesses from moving to the city.

SYDNEY (Reuters) - Scientists studying Antarctic waters have filmed and captured giant sea creatures, like sea spiders the size of dinner plates and jelly fish with six meter (18 feet) tentacles. A fleet of three Antarctic marine research ships returned to Australia this week ending a summer expedition to the Southern Ocean where they carried out a census of life in the icy ocean and on its floor, more than 1,000 meters (yards) below the surface.

Thank carbon for air cars
February 16, 2008 09:31 AM - , Private Landowner Network

One of the great success stories of recent technological history is carbon fiber. Light, stronger than steel and corrosion proof, it’s used in everything from airplanes to fishing rods to sailboat masts. Without carbon fiber composites Guy Negre wouldn’t have his air powered cars. It’s the super strong carbon fiber pressure tanks that make the cars possible. Soon cars running on compressed air will go into production – in India. MDI Industries, of Carros, France, which develops the air powered cars and engine technology, has signed a licensing agreement with Tata Motors that allows that company exclusive rights to manufacture and market an MDI car and its technology in the world’s second most populous nation. The small, fiberglass composite 770 pound (350 kg) cars could sell for about $5000.

Salmon's brain gives clues to pesticides toxicity in people
February 16, 2008 09:19 AM - ENN

In his research, scientist Nat Scholz examines how pesticides that run off the land and mix in rivers and streams combine to have a greater than expected toxic effect on the salmon nervous system. These pesticides are widely used in the United States and their occurrence as mixtures in the food supply for humans may also pose an unexpected risk for people.

U.S. moving toward ban on new coal-fired power plants
February 15, 2008 09:39 AM - Lester Brown, Earth Policy Institute

In a report compiled in early 2007, the U.S. Department of Energy listed 151 coal-fired power plants in the planning stages and talked about a resurgence in coal-fired electricity. But during 2007, 59 proposed U.S. coal-fired power plants were either refused licenses by state governments or quietly abandoned. In addition to the 59 plants that were dropped, close to 50 more coal plants are being contested in the courts, and the remaining plants will likely be challenged as they reach the permitting stage.

Green Mobile Phone: Stylish and Sustainable
February 15, 2008 07:23 AM - , Green Pages

Nokia has unveiled ReMade, a revolutionary mobile phone made of 100% recycled materials. The idea behind the “remade” concept was to see if it was possible to create a device made from nothing new. It has been designed using recycled materials that avoid the need for natural resources, reduce landfill, and allow for more energy efficient production.

Middle East collaborates on seismic mapping

Earth scientists from Israel, Jordan and Palestine have formed a research partnership to map seismic activity in the region. The collaboration began last month (January), according to lead scientist Hillel Gilles Wust-Bloch from the Minerva Dead Sea Research Center at Tel Aviv University in Israel, and the team are due to have a meeting next week (21 February).

Biofuel Crops Increase Carbon Emissions
February 12, 2008 11:25 AM - , Organic Consumers Association

The conversion of forests and grasslands into fields for the plants offsets the benefit of using the fuel, researchers find. Greenhouse-gas output overall would rise instead of fall The rush to grow biofuel crops -- widely embraced as part of the solution to global warming -- is actually increasing greenhouse gas emissions rather than reducing them, according to two studies published Thursday in the journal Science.

High Speed Rail Advances Globally, Crawls in the U.S.
February 12, 2008 10:50 AM - , Private Landowner Network

Somewhere deep in the pages of President Bush’s proposed 2009, $3.1 trillion budget is a 40 percent cut in Amtrak funding. A cut so deep that the quasi-government interstate passenger rail service could screech to a halt. The lame duck’s plan is to give Amtrak $800 million. Nearly on the same day that the President unveiled his budget Alstom, of France, unveiled its latest high speed train, the AGV (Automotrice y Grande Vitesse) ) a next generation replacement for the TGV (Train y Grande Vitesse). The company already has orders: 35 trains, with an option of 10 more to Italian rail operator NTV
