On a more cheery and less cynical note, could sunflower oil hold the key to a sustainable, renewable fuel future? Well, possibly, according to this Guardian story which I missed a little while back. I'm always slightly hesitant to post up stuff about fuels of the future, because I seem to have written about so many different types, none of which has ever come to fruition (see the Science and Energy section of the Global Ideas Bank for more). Still, this seems to have potential: "a hydrogen generator that uses only sunflower oil, air and water vapour", with the 'secret' being down to "two catalysts, one based on nickel, the other on carbon". Worth having a dry salad for, indeed.
