It's bad enough for some propeller aircrafts to be referred to as being powered by elastic band. Now the skeptics might start having a dig at commercial aircraft flying on whatever from cooking oil to liquefied algae.
With the civil aviation market under increasing pressure from rising oil prices and environmental legislation, the race is on to discover practical options to conventional kerosene and these so far seem to boil down to different types of biofuel.
Not remarkably, the first trials of alternative fuel were started by British aviation leader, Sir Richard Branson, whose Virgin Atlantic began London to Amsterdam flights with restricted biofuel use in 2008. This was quickly followed by Lufthansa and Air New Zealand who each used different blends of routine fuel and bio derivatives including some from made from jatropha which can grow in soil considered too poor for growing mainstream foodstuffs.
Jatropha is a genus of roughly 175 succulent plants, shrubs and trees (some are deciduous, like Jatropha curcas), from the household Euphorbiaceae.
In 2007 Goldman Sachs cited Jatropha curcas as one of the best candidates for future biodiesel production. It is resistant to drought and pests, and produces seeds containing 27-40% oil.
Recently, US aerospace giant Boeing, Brazilian aerial major Embraer and the Sao Paulo state Research Support Foundation relocated to carry out research and advancement into making use of biofuels to power jet airliners. It was reported that Brazilian airlines Azul, Gol, TAM and Trip would function as tactical experts for the task.
The current airline company to begin try out brand-new fuels is the Alaska Air Group which has actually performed internal US flights utilizing a blend of 80 % petroleum based fuel and 20% biofuel made from cooking oil. This mix, it is declared, can cut harmful emissions by 10%.
One actually has been the move far from biofuels which compete head on with food customers consequently preventing a rate spiral. Not so long earlier, a rise in use of biofuels in cars and trucks caused a spike in maize prices as US farmers diverted too much corn to fuel processing.
Hopefully in the future, airlines and drivers will focus biofuel intake on non-food sources such as jatropha curcas and algae. It would be a blended true blessing certainly if some people ended up starving simply to satisfy another person's green credentials.
