It's bad enough for some prop aircrafts to be explained as being powered by elastic band. Now the cynics could start having a dig at commercial airplane flying on everything from cooking oil to melted algae.
With the civil air travel market under increasing pressure from increasing oil prices and environmental legislation, the race is on to find feasible options to traditional kerosene and these so far appear to come down to different types of biofuel.
Not surprisingly, the first trials of alternative fuel were initiated by British aviation leader, 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 used different 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 items.
jatropha curcas 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 curcas as one of the finest prospects for future biodiesel production. It is resistant to dry spell and pests, 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 transferred to bring out research and development into the usage of biofuels to power jet airliners. It was reported that Brazilian airline companies Azul, Gol, TAM and Trip would serve as strategic experts for the job.
The latest airline company to begin explore brand-new fuels is the Alaska Air Group which has actually performed internal US flights using a mix of 80 % petroleum based fuel and 20% biofuel made from cooking oil. This mix, it is declared, can cut harmful emissions by 10%.
One truly encouraging advancement has been the relocation away from biofuels which compete head on with food customers consequently avoiding a rate spiral. Not so long earlier, a rise in use of biofuels in a spike in maize prices as US farmers diverted excessive corn to fuel processing.
Hopefully in the future, airline companies and motorists will focus biofuel consumption on non-food sources such as jatropha and algae. It would be a blended true blessing certainly if some people ended up starving simply to satisfy somebody else's green qualifications.
