It's bad enough for some propeller airplanes to be explained as being powered by . Now the cynics could start having a dig at commercial airplane flying on everything from cooking oil to melted algae.
With the civil aviation industry under increasing pressure from increasing oil rates and ecological legislation, the race is on to discover practical alternatives to conventional kerosene and these so far appear to come down to numerous kinds of biofuel.
Not remarkably, the very first trials of alternative fuel were initiated by British air travel leader, Sir Richard Branson, whose Virgin Atlantic began London to Amsterdam flights with minimal biofuel usage 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 thought about too bad for growing mainstream foodstuffs.
jatropha curcas is a genus of approximately 175 succulent plants, shrubs and trees (some are deciduous, like Jatropha curcas), from the family Euphorbiaceae.
In 2007 Goldman Sachs cited Jatropha jatropha curcas as one of the very best candidates for future biodiesel production. It is resistant to dry spell and pests, and produces seeds containing 27-40% oil.
Recently, US aerospace giant Boeing, Brazilian aeronautical major Embraer and the Sao Paulo state Research Support Foundation moved to perform research study and development into using biofuels to power jet airliners. It was reported that Brazilian airline companies Azul, Gol, TAM and Trip would act as strategic specialists for the project.
The current airline to start try out brand-new fuels is the Alaska Air Group which has carried out internal US flights utilizing a blend of 80 % petroleum based fuel and 20% biofuel made from cooking oil. This mixture, it is claimed, can cut damaging emissions by 10%.
One really motivating development has actually been the move far from biofuels which compete head on with food consumers thereby avoiding a cost spiral. Not so long earlier, a surge in usage of biofuels in vehicles caused a spike in maize costs as US farmers diverted excessive corn to fuel processing.
Hopefully in the future, airlines and vehicle drivers will focus biofuel usage on non-food sources such as jatropha and algae. It would be a mixed blessing certainly if some individuals ended up starving simply to please someone else's green qualifications.
