I've understood that it's some rubber or plastic parts that start to degrade, not the metals. I'm thinking it's just a new chip or reprogramming the ECU injection/ignition curves and an ethanol/gas ratio sensor, since you can tank either (hence the term flex-fuel). They probably slap in ethanol

A potentially weird aside: If woody feedstocks are effective, I wonder if the paper industry could make ethanol from their pulp, and still use the resultant stock for paper production? It's enough to drive Patzek and Pimental to drink: the drink you can drive does have a positive EROEI.

I was under the impression they already do. In Washington, the oxygenated gas was supposedly made from ethanol byproduct of the paper pulp industry, rather than the MTBE stuff. http://www.ethanol-gec.org/information/briefing/20a.pdf is an interesting report from 2000 on this. On 1/31/06, [EMAIL

the short ans is no, the pulp is the carbohydrate portion which must be hydrolyzed to afford the fermentable sugars. [EMAIL PROTECTED] wrote: A potentially weird aside: If woody feedstocks are effective, I wonder if the paper industry could make ethanol from their pulp, and still use the

The lignin is not fermentable so is not a significant source of ethanol. It may be possible to produce methanol from the lignin waste via destructive distillation. David Miller wrote: [EMAIL PROTECTED] wrote: A potentially weird aside: If woody feedstocks are effective, I wonder if the
