It's bad enough for some propeller planes to be referred to as being powered by elastic band. Now the skeptics might begin having a dig at industrial airplane flying on whatever from cooking oil to melted algae.

With the civil aviation market under increasing pressure from rising oil costs and environmental legislation, the race is on to discover viable options to traditional kerosene and these so far seem to boil down to numerous kinds of biofuel.

Not surprisingly, the first trials of alternative fuel were started by British aviation leader, 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 utilized different blends of routine 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 approximately 175 succulent plants, shrubs and trees (some are deciduous, like Jatropha curcas), from the household Euphorbiaceae.

In 2007 Goldman Sachs pointed out Jatropha curcas as one of the best 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 relocated to perform research study and development into making use of biofuels to power jet . It was reported that Brazilian airlines Azul, Gol, TAM and Trip would function as tactical specialists for the task.

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

One really motivating advancement has been the move away from biofuels which complete head on with food consumers consequently avoiding a rate spiral. Not so long back, a rise in usage of biofuels in vehicles triggered a spike in maize costs as US farmers diverted too much 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 individuals ended up starving simply to please somebody else's green credentials.
