It's bad enough for some propeller airplanes to be referred to as being powered by . Now the skeptics could start having a dig at industrial airplane flying on everything from cooking oil to melted algae.

With the civil air travel industry under increasing pressure from increasing oil prices and ecological legislation, the race is on to discover practical options to traditional kerosene and these up until now appear to come down to various kinds of biofuel.

Not remarkably, the first trials of alternative fuel were started by British air travel pioneer, Sir Richard Branson, whose Virgin Atlantic began London to Amsterdam flights with minimal biofuel use in 2008. This was quickly followed by Lufthansa and Air New Zealand who each utilized different 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 family Euphorbiaceae.

In 2007 Goldman Sachs pointed out Jatropha curcas as one of the very best candidates for future biodiesel production. It is resistant to dry spell 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 transferred to bring out research study and advancement into the use of biofuels to power jet airliners. It was reported that Brazilian airline companies Azul, Gol, TAM and Trip would function as strategic consultants for the project.

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

One really motivating advancement has been the move away from biofuels which compete head on with food consumers thus avoiding a cost spiral. Not so long back, a rise in usage of biofuels in automobiles caused a spike in maize costs as US farmers diverted excessive corn to fuel processing.

Hopefully in the future, airlines and drivers will focus biofuel intake on non-food sources such as jatropha and algae. It would be a combined blessing undoubtedly if some people wound up starving just to please another person's green qualifications.
