It is more than a year ago now, but on 7 January 2009 Continental Airlines was the first US airline to conduct a bio-fuel test flight with one of their Boeing 737-800s. One engine was running on a mixture of traditional jet fuel, algae and jatropha oil.
The 73 got a special paint job for the occasion, proclaiming the arrival of “eco-skies” on the side of the fuselage and winglets sporting a bright green color.
Continental was blasted by wary environmentalists for the extra paint job but they were reassured that the paint used was of the high solids kind and the surface treatment underneath was also of a modern, chromium-free type, both as environmentally friendly as they come.
N76516 had been spotted in its new livery all over the US but there is scant news on any follow up to this initial test.
Algae is renewable, does not affec the food channel and consumes CO2.
