It's bad enough for some propeller aircrafts to be referred to as being powered by elastic band. Now the cynics could begin having a dig at business airplane flying on everything from cooking oil to liquefied algae.
With the civil aviation market under increasing pressure from increasing oil costs and ecological legislation, the race is on to discover practical alternatives to standard kerosene and these up until now appear to boil down to various kinds of biofuel.
Not surprisingly, 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 restricted biofuel use in 2008. This was quickly followed by Lufthansa and Air New Zealand who each used various blends of regular 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 mentioned Jatropha curcas as one of the very best prospects for future biodiesel production. It is resistant to dry spell and insects, and produces of 27-40% oil.
Recently, US aerospace giant Boeing, Brazilian aeronautical significant Embraer and the Sao Paulo state Research Support Foundation moved to perform research study and advancement into using biofuels to power jet airliners. It was reported that Brazilian airlines Azul, Gol, TAM and Trip would function as strategic experts for the task.
The current airline company to begin try out new fuels is the Alaska Air Group which has carried out internal US flights utilizing a blend of 80 % petroleum based fuel and 20% biofuel made from cooking oil. This mix, it is claimed, can cut damaging emissions by 10%.
One truly encouraging advancement has been the move far from biofuels which complete head on with food customers thus preventing a rate spiral. Not so long back, a rise in usage of biofuels in automobiles triggered a spike in maize rates 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 and algae. It would be a blended true blessing certainly if some individuals wound up starving just to please another person's green qualifications.
