Well, it's all estimation right now, both in terms of the amount of
oil and NG in ANWR, and the environmental impact of drilling there.  I
don't have any hard numbers, but a quick cost-benefit analysis in mind
comes back inconclusive.  Sure, it may be feasible, and it may be
worthwhile, but is anyone really arguing that it's the answer to anything?

No offense, but who cares?  Every country in the world exports and
imports all manner of things, including money, energy, jobs, etc.  No
one will never be totally independent of every other nation, and why
would we want to be?  Do we want to be some huge fortress on a hill
that never lets anything in or out?  I personally don't have any
interest in investing money or land in this goal.

I say: do what makes economic sense.  And right now, importing oil
from the OPEC countries makes economic sense.  Hailing drilling in
ANWR as an answer to high oil prices is short-sighted at best, and
environmentally malicious at worst.

Significant start to what?  Again, I think you and I have different
goals here.

See my other post about the renewable nature and significant negative
impact of fossil fuels.

You know, "The" energy problem...  The one where we are almost totally
dependent on dwindling, dirty fossil fuels to power our lives...?

Yeah, I don't really know what I'm talking about here either. :)

I was just guessing as to Bob's meaning is his comment about
E85-optimized engines.  I'm certain he is well aware of flex-fuel
engine technology.

I do know that ethanol (and consequentially, E85) has a lower energy
content than gasoline, which does make it less efficient in flex-fuel
engines.  I'm thinking that Bob's comment about higher-compression
engines (E85 has a higher octane rating than gasoline, which means it
can take higher compression without detonation) is key to getting the
most efficiency out of E85.

Eh, no big deal.  I got it.

So you don't think that that attitude is cutting off your nose despite
your face?

Is it really all that uncertain whether or not solar (or wind, or
hydro) is cleaner than petroleum?  Nuclear, I'll admit, is not
perfect, but it's a damn sight better than petroleum on a lot of fronts.

Saying that these technologies are prohibitively dirty to implement
due only to the dirty technology they are replacing is a huge fallacy
of logic...  It's a catch-22.

Also, I don't see any reason why switching to cleaner energy sources
will increase pollution at all, even in the short run.  "Switching"
means that the truck that carried gasoline yesterday will carry E85
today.  We're not talking about adding a truck, just re-purposing the
ones not needed anymore, because of the switch.

Does that make sense?
