It's bad enough for some prop airplanes to be referred to as being powered by rubber bands. Now the skeptics might begin having a dig at business aircraft flying on whatever from cooking oil to melted algae.
With the civil air travel industry under increasing pressure from increasing oil costs and ecological legislation, the race is on to discover viable alternatives to traditional kerosene and these up until now seem to boil down to different kinds of biofuel.
Not remarkably, the very first trials of alternative fuel were started by British aviation pioneer, Sir Richard Branson, whose Virgin Atlantic started 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 including some from made from jatropha curcas which can grow in soil thought about too bad for growing mainstream foods.
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 very best candidates for future biodiesel production. It is resistant to dry spell and bugs, 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 making use of biofuels to power jet airliners. It was reported that Brazilian airlines Azul, Gol, TAM and Trip would act as strategic experts for the task.
The most recent airline company to begin try out new fuels is the Alaska Air Group which has actually carried out internal US flights utilizing a blend of 80 % 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 relocation away from biofuels which contend head on with food consumers therefore preventing a cost spiral. Not so long earlier, a rise in usage of biofuels in automobiles caused a spike in maize costs as US farmers diverted excessive corn to fuel processing.
Hopefully in the future, airlines and motorists 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 satisfy another person's green credentials.
