Coconut Jet Fuel and the Icarus Moment


The idea of a plane powered by coconuts sounds quite funny, but when I read about this in the papers the other day it didn't make me laugh. Instead it made me think of Icarus, the unfortunate flying boy. He tried to fly too high and melted his wings, confirming the view that people ought to stay put on terra firma and not act like gods. The Greeks had a word for this sort of behaviour: Hubris. In their myths people who put on airs and graces were guilty of hubris and generally came to a sticky end. Prometheus is another example.

Cut to 2008 and people are concerned about the environmental impact of cars and planes. We want to go wherever we want quickly, but oil is getting more expensive and our journeys are releasing ever-increasing amounts of carbon into the atmosphere. I don't claim to be an expert Carbon-cruncher, but wiser heads have pointed out that carbon released high in the atmosphere causes more trouble than the same amount released at ground level. Yes, we're back with Icarus...

Airlines are attracting more and more customers but they're not enjoying the bad publicity. So a certain British businessman, who owns an airline, hit on the idea of putting biofuel in the gas tanks of a 747. Of the jet's four tanks, three contained ordinary jet fuel, while the last had a mixture of 80% jet fuel and 20% fuel made from coconut and babassu palm oil. Apparently 150,000 coconuts were used, along with an unspecified amount of palm oil. I'm no mathematician, but that sounds like an awful lot of coconuts to provide a small percentage of one airplane's fuel.

The entrepreneur in question described the flight as 'historic', and perhaps it is. Perhaps this was the moment when the human race finally took leave of its senses. The Icarus moment.

Biofuels are made from living plants, which absorb carbon as they grow. The idea is that, on balance, a car or jet running on biofuel emits less carbon than one using ordinary fuel. Groans point to this and say, Here is the future of transport! And that future is bright leafy Green!

What they never mention is that all these plants - oil palms, rape, wheat - have to grow somewhere. Land which might have been used to grow food or left alone for wildlife has to be cleared and planted with biofuel crops. These are not cosy little farms but vast plantations run by big companies that want to make as much money as they can - what they do is called Green because people have this obsession with carbon, but isn't even remotely Green. It's hugely destructive. Oil palms grow in the tropics, which means rainforest is being cut down and burned to make way for them. The oran utang is losing its home so that people in Europe can put biofuels in their petrol tanks and feel all virtuous and Green.

And now people want to power jets with coconuts! This isn't Green, this is Gruesome, Grisly Groanishness of the first order. It's unbelievably stupid. By contrast, Icarus was just a kid who forgot where he was.
