It's bad enough for some prop aircrafts to be described as being powered by rubber bands. Now the skeptics might begin having a dig at commercial aircraft flying on whatever from cooking oil to liquefied algae.

With the civil aviation market under increasing pressure from rising oil costs and ecological legislation, the race is on to discover viable options to standard kerosene and these up until now seem to boil down to different kinds of biofuel.

Not remarkably, the very first trials of alternative fuel were initiated by British air travel pioneer, Sir Richard Branson, whose Virgin Atlantic started London to Amsterdam flights with restricted biofuel usage in 2008. This was rapidly 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 bad for growing mainstream foods items.

Jatropha is a genus of roughly 175 succulent plants, shrubs and trees (some are deciduous, like Jatropha curcas), from the household Euphorbiaceae.

In 2007 Goldman Sachs mentioned as one of the very best candidates for future biodiesel production. It is resistant to drought and bugs, 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 relocated to perform research and advancement into the usage of biofuels to power jet airliners. It was reported that Brazilian airline companies Azul, Gol, TAM and Trip would function as strategic experts for the project.

The newest airline company to begin explore brand-new fuels is the Alaska Air Group which has carried out internal US flights utilizing a mix of 80 % petroleum based fuel and 20% biofuel made from cooking oil. This mixture, it is declared, can cut harmful emissions by 10%.

One really motivating advancement has actually been the relocation away from biofuels which complete head on with food customers consequently avoiding a price spiral. Not so long back, a rise in usage of biofuels in vehicles triggered a spike in maize rates as US farmers diverted too much corn to fuel processing.

Hopefully in the future, airline companies and vehicle drivers will focus biofuel usage on non-food sources such as jatropha and algae. It would be a blended true blessing undoubtedly if some people wound up starving just to please somebody else's green credentials.
