It's bad enough for some propeller planes to be explained as being powered by rubber bands. Now the skeptics could begin having a dig at commercial airplane flying on everything from cooking oil to melted algae.
With the civil aviation industry under increasing pressure from increasing oil rates and environmental legislation, the race is on to discover viable alternatives to conventional kerosene and these up until now appear to boil down to various types of biofuel.
Not surprisingly, the very first trials of alternative fuel were initiated by British air travel leader, Sir Richard Branson, whose Virgin Atlantic began London to Amsterdam flights with minimal 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 including some from made from jatropha which can grow in soil thought about too poor 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 cited Jatropha jatropha curcas as one of the very best prospects for future biodiesel production. It is resistant to drought and bugs, and produces seeds containing 27-40% oil.
Recently, US aerospace giant Boeing, Brazilian aerial major Embraer and the Sao Paulo state Research Support Foundation relocated to perform research and advancement into the usage of biofuels to power jet airliners. It was reported that Brazilian airlines Azul, Gol, TAM and Trip would function as tactical consultants for the task.
The current airline company to start explore brand-new fuels is the Alaska Air Group which has actually performed internal US flights utilizing a blend of 80 % petroleum based fuel and 20% biofuel made from cooking oil. This mixture, it is declared, can cut damaging emissions by 10%.
One really encouraging advancement has actually been the move far from biofuels which compete head on with food customers consequently avoiding a cost spiral. Not so long back, a rise in usage of biofuels in cars and trucks triggered a spike in maize prices as US farmers diverted excessive corn to fuel processing.
Hopefully in the future, airline and motorists will focus biofuel usage on non-food sources such as jatropha curcas and algae. It would be a mixed true blessing undoubtedly if some individuals wound up starving simply to please somebody else's green credentials.
