At what cost?  Seems to me that the benefits aren't all that great. 
What goal are we trying to accomplish by reducing dependency on
foreign oil?

I never meant to imply that we couldn't be independent of foreign oil.
 I just don't think domestic drilling is the "answer".  It's a
pathetic band-aid.  Yeah, okay, it has its upsides, but it's more like
a back pocket idea.  We should be focusing on alternate energy
sources, not just where we're going to get our next petroleum fix.

I want to solve the energy problem, not just make gas cheaper.

Yeah, that's what I was trying to say.  Flex-fuel vehicles (like my
old Taurus and my new Tahoe) are dual-fuel vehicles.  Engineers don't
sit down at a clean drawing board when they design those engines,
because at the end of the day, they still have to run on regular old
gasoline.  They take an existing engine, give it a computer smart
enough to "taste" the difference between the two fuels (and any
continuously variable mixture of the two) and fuel components hardy
enough to take the rigors of E85.  It's a compromise, it's not optimal
for E85-efficiency.

It was my understanding that Bob was referring to engines that could
be physically designed from scratch to be optimized to running E85
ONLY.  I don't doubt that these kinds of engines could be more
efficient that regular gas engines (but I don't actually know, just
trying to clarify what I thought Bob was saying).

Huh?  Are we maybe talking about two different things here?  I heard
electric vehicles, solar, wind, photovoltaics and nuclear.  Where did
E85 come in?

But in answer to your question, yes, E85 (and energy storage for the
other technologies I was talking about) is currently transported the
same old way, which contributes to atmospheric carbon and fossil fuel
dependency.  But surely that doesn't lessen the value or necessity of
the concepts themselves.  In my mind, it raises it.  A paradigm shift
to clean(er) energy sources will take care of its own manufacturing,
shipping, etc. dirtiness.
