A US-built Tesla Roadster has broken the world record for the distance travelled by an electric production car on a single charge.

While competing in the Global Green Challenge, Australian Simon Hackett and co-driver Emilis Prelgauskas drove an incredible 313 miles before the batteries finally died in their Roadster.

Until now, the record has been held by another Tesla Roadster, after completing a 241 mile road rally on one charge.

Sigourney Weaver narrates “Acid Test“, an illuminating and terrifying NRDC documentary that explains how quickly our planet’s oceans are acidifying due to all of the carbon dioxide that we are pumping into our air. This pollution is causing rapid changes in our oceans’ chemistry that will completely disrupt all life on the planet as we know it on a scale that has not been seen for tens of millions of years.

Naked bicyclists, folding bikes, balloon bikes, and more — enjoy this bicycle photo tour of Barcelona.

The third B in a row, Barcelona is next on this list of great bicycle cities (right ahead of Basel, Switzerland and Bogota, Columbia). As a dense city with a wonderful climate, Barcelona is naturally a wonderful place for bicyclists. However, a lot has been done to make it more so. The biggest carrot encouraging bicycling, by far, is Barcelona’s relatively new bike sharing program — Bicing. This is perhaps the best or second best bike sharing program in the world. It is one of a new generation of sophisticated, smart bike sharing programs. Read more about it on page 2.

Beyond Bicing, the city is also working on creating new bicycling routes and bike parking and it hosts fun Bike Week celebrations every year in May. Also, it has been creating better infrastructure for bicyclists due to so many more people bicycling within the past few years. It is transforming itself into a truly world-leading bicycle city.

Legendary Italian carmaker, Pininfarina, may yet have some surprises up its sleeves. Even with recent financial difficulties, Pininfarina’s CEO, Silvio Pietro Angori, told Italian newspaper, Il Sole 24, that the company’s Bluecar electric car venture with french investor Vincent Bollore is not simply a concept car and still on track for a 2011 market debut.

Comedian Sarah Silverman explains her ambitiously brilliant plan to end world hunger. She calls on Ratzinger, the chief architect responsible for obfuscating many of the Catholic Church’s most horrific sexual abuse scandals, to sell the Vatican and feed the world with the money.

“We need a hero, and who is more primed to be our hero than the pope? He’s literally a caped crusader,” explains Silverman. I think

Norway committed to cut their greenhouse gas emissions 40% by 2020 this week. This is the most ambitious goal of any rich nation to date.

Norway’s prime minister Jens Stoltenberg (just re-elected) is meeting the requests of many developing nations and environmental NGOs with this commitment.

GASP!     WOOT! YES!

President Barack Obama was awarded the 2009 Nobel Peace Prize today for “his extraordinary efforts to strengthen international diplomacy and cooperation between peoples“; as well as for his ongoing work to free the world of all nuclear weapons.

Clean tech has passed biotech and IT as the top venture capital (VC) investment category in the world. This is after investments in leading clean tech markets increased by 10% in the third quarter of this year.

Cleantech Group released findings on Wednesday showing that the cleantech sector “accumulated $1.59 billion across 134 companies” and this was 10% more than the $1.2 billion it had accumulated in the second quarter.

A new report ranks ten leading world cities on their greenhouse gas emissions. It also examines how and why the emissions differ.

As the report says, over 50% of the world’s population lives in urban areas. Leading cities of the world, global cities, are the places where greenhouse gas emissions really need to be cut. The greenest city from the study is Barcelona and the worst is Denver.

A new study by nearly 30 of the world’s best scientists concludes that we have crossed three of the world’s nine thresholds. It is not only about climate change.

Climate Action Will Pay for Itself, and More.

The United Nations (UN) stated earlier this month that the cost of avoiding climate change was at least 1% of global GDP — $500-600 billion dollars. Despite this major cost, Tony Blair, former Prime Minister of the UK, and The Climate Group, presented a report to the UN yesterday saying that a strong climate deal will “boost growth in all major economies & create millions of new jobs.”
