Renewable Revolution

I am sure that the ERoEI of bio-mass to ethanol is a different thing from the ERoEI of ethanol to miles motored, and a different thing again from the ERoEI of oil to miles motored. We want to know the ERoEI of bio-mass to miles motored.  Since we can't do that without first doing the other two, wouldn't it be sensible to do bio-mass to ethanol first?  If my figures say 1.2 and yours say 10, we have to stop and line the factors up and see where the huge difference arises.  If it turns to all come from your ERoEI for fossil fuels being different from mine, then we will have got somewhere.

I'm not playing dumb, but I do seem to be having a lot of difficulty in getting you to be focussed on solving something.  And you do know you are being insulting all the time, don't you?  That doesn't help.
