<Here's another one, diesel plus 3% methanol [or ethanol] plus [approximately] 3% de-ionized water in the methanol for neutral buoyancy, plus emulsifier and maybe ignition improver for cheap, clean-burning fuel for diesel engines. //Is this essentially the same vein as ethanol use in gasoline (replacing MTBE) ?//> Kastel, not really. It is in the sense that it's a way of using alcohols as fuel extenders. But with gasoline, the ethanol, or methanol, are not in the form of little balls of ethanol. They are miscible up to a small proportion [depending on the nature of the gasoline being used]. They appear to be in solution. The ethanol molecules are not joined together in gasoline as they would be in diesel. Also, the density of ethanol and gasoline are similar [though not the same]. Phase separation is a hazard. With diesel, the alcohols need to be made into little spheres because they won't dissolve in the diesel. They would float to the surface, which is why the water needs to be added. The water and alcohol make the combustion process cleaner. So, they seem to be in the same vein, but technologically they are very different. Mqurice
