I have had a car running on home-made ethanol, but abandoned the project in favour of biodiesel, mainly on cost grounds. There is, however, another aspect of ethanol which disquiets. Most proponents cite the carbon dioxide released during fermentation as some sort of advantage, saying it promotes plant growth or can be used to make fizzy drinks. No mention of either: * Its role as a greenhouse gas or * The loss of energy in all that carbon In one sense, fermentation is a cold combustion process so we are squandering a decent part of the energy in the original feedstock sugars.
Or have I got it all wrong? David T.
