It's bad enough for some propeller planes to be described as being powered by rubber bands. Now the cynics could start having a dig at commercial airplane flying on everything from cooking oil to liquefied algae.
With the civil air travel industry under increasing pressure from increasing oil rates and environmental legislation, the race is on to discover feasible options to standard kerosene and these up until now seem to come down to various kinds of biofuel.
Not remarkably, the very first trials of alternative fuel were started by British aviation pioneer, Sir Richard Branson, whose Virgin Atlantic began London to Amsterdam flights with minimal biofuel usage 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 considered too poor for growing mainstream foodstuffs.
jatropha curcas is a genus of approximately 175 succulent plants, shrubs and trees (some are deciduous, like Jatropha jatropha curcas), from the household Euphorbiaceae.
In 2007 Goldman Sachs cited Jatropha curcas as one of the finest prospects for future biodiesel production. It is resistant to drought and insects, and produces seeds consisting of 27-40% oil.
Recently, US aerospace giant Boeing, Brazilian aerial significant Embraer and the Sao Paulo state Research Support Foundation relocated to perform research study and development into the usage of biofuels to power jet airliners. It was reported that Brazilian airlines Azul, Gol, TAM and Trip would act as strategic consultants for the job.
The most current airline to start try out is the Alaska Air Group which has performed internal US flights using a mix of 80 % petroleum based fuel and 20% biofuel made from cooking oil. This mixture, it is claimed, can cut harmful emissions by 10%.
One really motivating advancement has actually been the move far from biofuels which compete head on with food consumers thereby preventing a cost spiral. Not so long ago, a rise in use of biofuels in vehicles triggered a spike in maize rates as US farmers diverted excessive corn to fuel processing.
Hopefully in the future, airline companies and drivers will focus biofuel consumption on non-food sources such as jatropha curcas and algae. It would be a blended true blessing undoubtedly if some people ended up starving simply to please another person's green qualifications.
