It's bad enough for some propeller aircrafts to be referred to as being powered by rubber bands. Now the skeptics might begin having a dig at commercial airplane flying on whatever from cooking oil to melted algae.
With the civil air travel market under increasing pressure from increasing oil rates and ecological legislation, the race is on to find feasible alternatives to traditional kerosene and these so far seem to boil down to numerous types of biofuel.
Not remarkably, the first trials of alternative fuel were started by British aviation leader, Branson, whose Virgin Atlantic 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 routine fuel and bio derivatives consisting of some from made from jatropha which can grow in soil considered too poor for growing mainstream foods items.
Jatropha 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 pointed out Jatropha curcas as one of the very best candidates for future biodiesel production. It is resistant to dry spell and insects, 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 bring out research and development into the use of biofuels to power jet airliners. It was reported that Brazilian airlines Azul, Gol, TAM and Trip would function as strategic consultants for the job.
The most recent airline to start explore new fuels is the Alaska Air Group which has actually carried out internal US flights using a blend of 80 % petroleum based fuel and 20% biofuel made from cooking oil. This mixture, it is claimed, can cut hazardous emissions by 10%.
One truly encouraging development has actually been the move away from biofuels which contend head on with food customers thereby avoiding a rate spiral. Not so long back, a surge in usage of biofuels in cars caused a spike in maize rates as US farmers diverted too much corn to fuel processing.
Hopefully in the future, airlines and motorists will focus biofuel intake on non-food sources such as jatropha and algae. It would be a mixed blessing certainly if some people wound up starving simply to please somebody else's green credentials.
