That's why Mittermeier and I are here, to see Madagascar's wildlife while we can, and to see what's being done to save it. After a day in Antananarivo - a sprawling, diesel-soaked city that earns the adjective "teeming" - we leave by car for Andasibe, a former logging village that is now home to a burgeoning ecotourism trade. On the winding road we see the result of centuries of tavy, traditional slash-and-burn agriculture. The verdant forests that once covered much of Madagascar have been burnt or torn down, replaced by muddy rice paddies and secondary shrubs...
...ordinary South African and I am amazed that you publish such disparaging rubbish about Sasol. Perry's pernicious tone is an attempt to blacken Sasol's achievements. Sasol technology is being used in several countries around the world because it is the most advanced. Sasol gasoline and diesel has never been produced in sufficient quantity to prop up any government. Contrary to Perry's comments, CTL and GTL fuels are likely to play a major role in the future. This is why so many different countries are commissioning plants to produce them. Why didn't Perry look a little deeper...
...course, nothing's ever that simple in the energy business. Sasol's end product is cleaner than the average diesel fuel or gasoline, emitting less sulfur and less nitrogen when it burns, says Barrows. Coal-to-liquid plants can also be used to clean up the mountains of coal left over at old mines. But in terms of carbon emissions, Fischer-Tropsch is dirty. A sliding scale of emissions from fossil fuels, goes: coal, petroleum, methane. Coal emits the most carbon dioxide per unit of energy obtained. The resultant fuel also emits more carbon dioxide when burned...
Another potential hurdle: Audi is pushing its superb diesel technology as the best way to cut emissions and lower fuel consumption. But diesels remain a hard sell in the U.S., where memories of dirty, noisy, sluggish diesels of an earlier era linger like smog. Nonetheless, Audi expects that 10% to 15% of its cars sold in the U.S. by 2015 will be diesel...
Puny greenbacks and diesel issues aside, Garel Rhys, an emeritus professor of automotive economics at Cardiff Business School, says, "Audi's closing the gap quickly." Five years ago, Audi wasn't competitive, but now it outsells BMW in several European markets. Nagley's not sure there's much that BMW can do to halt that design-driven momentum. "It's not been able to stop Audi in Germany, the U.K. and the rest of the world, so why should it be able to stop it in America...
