...proving today is that biofuel can be used for a plane," Branson told reporters. "Two years ago, people said it was absolutely impossible." Among the fears: that biofuel would freeze before a plane reached cruising altitude, or that it would require massive and costly changes to the aircraft or fueling systems to work at all. Those prognosticators were proved wrong. The fuel Virgin used Sunday required no equipment modifications at all; the plane flew to 25,000 feet (7,600 m) without incident; and the environmental benefits seem clear, at least once the fuel is loaded onto the plane. Internal...
...people are growing ever more worried that biofuel production can drive up the prices of staple foods. Tens of thousands of Mexicans marched in January 2006, for example, to protest the rising price of corn, used in the U.S. to make ethanol. Virgin and partners claim that their airplane fuel is, as Branson says, "completely environmentally and socially sustainable." It's not made from staple-food crops or from crops that required deforestation. But even coconuts and babassu have their problems: the oil yield is just not that high. If a 747 could run on coconut oil alone, it would...
...London Heathrow's two main runways and took off into the bright sky late Sunday morning. First, there were only five people on board, while more than 100 watched intently from a nearby hangar. Second, the plane was the first commercial jet ever to fly on biofuel, a fuel produced from plant matter instead of petroleum or other fossil fuels. "This is the first stage on a journey towards renewable fuel," Virgin founder Richard Branson told reporters in the hangar shortly before takeoff, his voice drowned out every now and then by the roar of overhead planes...
...happens, Virgin's eco-plane ran only one engine on the experimental fuel; the other three burned standard jet fuel. And the biofuel-powered engine was using a blend of conventional jet fuel and biofuel: 80/20 in favor of the regular stuff. In total, then, just 5% of the 49,000-lb (22,000 kg) fuel load consisted of the novelty: a special mix of coconut oil and oil from the Brazilian babassu plant, prepared by Seattle-based Imperium Renewables over the last 18 months and tested by General Electric Aviation in Ohio...
...hardly an investment-friendly environment, with fuel prices lately having more than doubled and the rebels imposing their own informal taxes on anyone doing business in the town...
