Biofuelled 747

[siznaudin]

Well, sort of anyway .. heard on the steam powered radio this morning that KLM have flown a 747 on (well, partly on ..) bio fuel. It sounded like a promo cum publicity stunt more than anything else - only one engine was run on a 50-50 mix of JetA1 and the "green" fuel, and the other three stayed with good old fossil fuel.

 

Said green fuel only needs 3 squillion hectares of otherwise food-producing arable land for its production, which leaves one wondering how the world will be able to feed itself while we hurtle around the planet in carbon neutral fuelled lumps of aluminium, doesn't it!
