On a different tangent, when we geta reply from a fuel expert, something that I have been wondering over.
In Sweden there is an alternative diesel called RME, which comes from rapseed oil. As diesel cars will run on kerosine, can RME be refined to run jet engines?
I am sure there is a simple reason why not.
Also in Sweden we have many cars that run on ethanol85, a mix of 85% ethanol and 15%petrol. Nearly all Ford Focus and many Saabs. But the drawback is that ethanol does not vapourise below -5degC, so your car doesn't start in the winter. You get round this with a heater for the engine which plugs in the mains, but if you are away from home, you are snookered.
