It's bad enough for some propeller airplanes to be explained as being powered by rubber bands. Now the skeptics might begin having a dig at industrial airplane flying on everything from cooking oil to melted algae.
With the civil air travel market under increasing pressure from increasing oil prices and ecological legislation, the race is on to find feasible options to standard kerosene and these up until now appear to come down to different kinds of biofuel.
Not remarkably, the first trials of alternative fuel were initiated by British aviation leader, Sir Richard Branson, whose Virgin began London to Amsterdam flights with limited biofuel use in 2008. This was rapidly followed by Lufthansa and Air New Zealand who each utilized various blends of regular fuel and bio derivatives consisting of some from made from jatropha which can grow in soil thought about too poor 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 household Euphorbiaceae.
In 2007 Goldman Sachs mentioned Jatropha curcas as one of the very best candidates for future biodiesel production. It is resistant to drought and bugs, and produces seeds consisting of 27-40% oil.
Recently, US aerospace giant Boeing, Brazilian aeronautical major Embraer and the Sao Paulo state Research Support Foundation relocated to bring out research study and advancement into using biofuels to power jet airliners. It was reported that Brazilian airlines Azul, Gol, TAM and Trip would serve as strategic consultants for the project.
The current airline to start try out brand-new fuels is the Alaska Air Group which has conducted 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 hazardous emissions by 10%.
One truly encouraging development has actually been the move away from biofuels which compete head on with food customers consequently avoiding a cost spiral. Not so long ago, a rise in usage of biofuels in automobiles caused a spike in maize rates as US farmers diverted too much corn to fuel processing.
Hopefully in the future, airline companies and motorists will focus biofuel usage on non-food sources such as jatropha and algae. It would be a mixed blessing certainly if some people ended up starving simply to satisfy somebody else's green qualifications.
