It's bad enough for some propeller aircrafts to be explained as being powered by elastic band. Now the could begin having a dig at industrial airplane flying on whatever 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 discover practical options to standard kerosene and these up until now appear to come down to numerous types of biofuel.
Not remarkably, the first trials of alternative fuel were initiated by British aviation leader, Sir Richard Branson, whose Virgin Atlantic began London to Amsterdam flights with limited biofuel usage in 2008. This was quickly followed by Lufthansa and Air New Zealand who each used various blends of routine fuel and bio derivatives consisting of some from made from jatropha which can grow in soil thought about too bad for growing mainstream foods.
Jatropha is a genus of around 175 succulent plants, shrubs and trees (some are deciduous, like Jatropha curcas), from the household Euphorbiaceae.
In 2007 Goldman Sachs pointed out Jatropha curcas as one of the finest prospects for future biodiesel production. It is resistant to dry spell and insects, and produces seeds consisting of 27-40% oil.
Recently, US aerospace giant Boeing, Brazilian aeronautical significant Embraer and the Sao Paulo state Research Support Foundation moved to carry out research study and advancement into the use of biofuels to power jet airliners. It was reported that Brazilian airlines Azul, Gol, TAM and Trip would serve as strategic experts for the job.
The current airline to begin explore new fuels is the Alaska Air Group which has conducted internal US flights using a blend of 80 % petroleum based fuel and 20% biofuel made from cooking oil. This mix, it is declared, can cut harmful emissions by 10%.
One actually encouraging advancement has been the move away from biofuels which contend head on with food customers thus preventing a rate spiral. Not so long earlier, a surge in use of biofuels in cars and trucks triggered a spike in maize costs as US farmers diverted too much corn to fuel processing.
Hopefully in the future, airlines and vehicle drivers will focus biofuel intake on non-food sources such as jatropha curcas and algae. It would be a mixed blessing indeed if some individuals ended up starving simply to satisfy another person's green credentials.
