I agree.

But remember I was only responding to others claims about ethanol producing
more energy than it takes to manufacture it - hence the subject, Ethanol a
net energy loss. I said *nothing* about whether it's personally worthwhile
for different individuals, so why all the long argument about that?

When people make claims *to others* about home energy production and fail to
put a dollar value on their own labor, they're misleading people. If they
produce it and forget about their own labor, but don't make claims *to
others* about what it cost, no problem obviously. When I grow food, I don't
tell others it only costs the price of hand tools and seed, as if my time and
labor wasn't necessary for growing. People disagree about the details of
cost, but to leave out one's own labor when arguing production costs is worse
than misleading; it's dishonest.

I hope you understand my point now. I'm not going to keep discussing ethanol
maufacture because it's not what this list is for.
