and these are just the main lines, there are literally thousands of smaller arteries going to just about every town i america, what is the problem again?

$this->bbcode_second_pass_quote('pstarr', '')$this->bbcode_second_pass_quote('TheAntiDoomer', 'w')hat is the problem again?

south dakota and Oregon and anyplace a natural gas car can't drive to. Can you imagine renting a car at the Vegas Airport and told you must stay in Vegas :shock:


HUH?

1) For Vegas I'd imagine most folks are staying within the 200-300 or more range of the nat gas vehicle.
2) They could still rent gasoline cars for those willing to pay the premium for gasoline
3) Natural gas pipelines will naturally be extended to those areas with demand.

:? :shock: I'm shocked at your poor rebuttal :(

Holy Cow! I never realized that natural gas lines reached so many places around the country. Combined with the newly discovered natural gas volumes everyone is talking about:

we might be looking at traffic jams quite a bit further into the future than most of us would like.

I regularly ride bikes with a group of guys that work for JB Hunt, which you all may know is one of the biggest long haul trucking carriers in the US. I asked just last night about moving to NG trucks. They said they had a total of 3, for local routes, and purchased only at the demand of the particular client. That the trucks are too expensive to justify the cost and can't be used on long haul routes bc no service/support infrastructure for them. In addition, the county where I lived looked at transitioning its vehicles to NG but decided against it bc there was no cost savings and the cost to put in the infrastructure was out of reach. So, despite all the cheap NG, no one is using it for vehicles in any appreciable manner to transition off of oil yet. I suspect that until Congress does something along the lines of what Boone Pickens is proposing, nothing will happen. Further, even after that happens, it simply takes a lot of time and money to put in the infrastructure, change fleets over, etc to make an appreciable difference. Since we haven't started, NG should be cheap for a long time. I'm all for it, and have bought stock in Picken's company CLNE, but the reality is, its a long way from going from dream to reality.

Right. So it's all up to the price of oil. Chindia and the relative inaccessability on average of meaningful new finds tells us where that HAS to go, on average, as the years pass. (Green tech. may help eventually, but short term demand will overwhelm it for at least a decade, IMO).

So in the U.S., we'll sit on our asses and (helplessly - for J6P) watch the oil price rise over time, until FINALLY it is at a sustained average price high enough to really piss the overall public off and get them OFF their collective asses and reaming politicians who keep doing nothing.

Then, we'll START UP a process to do something, such as this logical project, which will take years to get to sufficient scale to help.

Brilliant. It is so great to live in the only remaining military superpower country (at present) and have political leaders with a planning horizon of the next election cycle, or maybe just the next press release. :evil:

Of course, we could also try to mitigate this with an intelligent action like a rising gasoline and diesel tax (with an offsetting credit to the poor, for everyone who will now cry "unfair") -- to help get us to the required-action gasoline price point sooner, help prevent us from bankrupting the country, and perhaps even start to meaningfully maintain our transportation and energy infrastructures.

Pick a number. I like 50 cents a gallon per year for 5 years, and then see where we are. It would be progress, and wouldn't even put us at fuel cost parity with Europe at that point.

But nope -- no planning ahead, no potential slowing of BAU growth -- that would be "unamerican". :roll:
Given the track record of the perma-doomer blogs, I wouldn't bet a fast crash doomer's money on their predictions.

There is still too much oil around to justify the transition. A horrible idea, and one which will be exposed one day/month/year/decade for the farce that it is, but without either the price or supply restrictions to cause enough uncertainty for business, no one will willingly make the transition.

You are quite correct. There will always be too much oil around to ever transition to NG, coal, or fairy dust.


That is not fair. The "transition" (in the sense of the word that the technologies are already being used and work) has already begun, otherwise I would not be able to ride the CNG powered buses to and from the airport. The issue appears to be more one of scale, everyone cannot make a clean transition from a crude powered personal transport car to a CNG powered one some afternoon just because. Much like the transition from EV to ICE power on American roads a century ago, it is a gradual process which, fortunately for us Americans (in the sense that we really like them), can unfold over a matter of decades, exactly as Hirsch has stated. I think he is off base in the sense that no real timing link to peak oil is required, but the time frames he has stated seem reasonable.

$this->bbcode_second_pass_quote('pstarr', ' ')

We can't afford to maintain the current pipeline infrastructure. It's slowing rusting and collapsing and you expect to cover vast swatches of the US with additional pipelines?

Indeed, and they often fail with spectacular results, destroying entire neighborhoods.
http://www.naturalgaswatch.org/?p=219
Another reason to keep NG pipelines few and far between, and only feeding generating plants to use the NG efficiently and not squander it in inefficient ICE vehicles.
NG might not be as plentiful and easy to get as thought.

can you please explain further why LPG is more efficient than natural gas or oil?

$this->bbcode_second_pass_quote('pstarr', 'H')irsch was not interested in NG-powered buses.


True. Unfortunate that he didn't have time to include items which obviously are already part of the transition, even back when he wrote the report.

$this->bbcode_second_pass_quote('pstarr', '
')His call was for peak-oil mitigation and implementation initiated at least 20 years (preferably 30) before the onset of decline to avoid social/economic catastrophe.


True. And then peak oil happened the year he wrote the report. And here we all are still talking about it. Worse yet he assumed that supply in all sorts of ways would be increasing with these little wedge type things. That fell apart the year after he wrote the report because we didn't get any increase in supply. Or decrease either I don't believe. Maybe he can rerun his model with the past 5 years of actual changes? Might come back with something more akin to the recession it caused rather than social/economic collapse?

$this->bbcode_second_pass_quote('pstarr', '
')Hughy (or should I call you fairy-dust boy 8) ) NG buses represent a specific application designed for exactly one purpose---fixed, short, circuitous, urban, public, transport routes. Don't confuse this application with other different applications---long-haul trucking, mining, ocean-going shipping, inter-city automobile travel, mom/the kids driving around, Hughy dating, etc.---for which NG ICE's are roundly inappropriate.


Not knowing who Hughy is, I shall simply note that some applications are good for some things, and some applications for others. If the average American is offered no gasoline for their current car, or plenty of CNG for a car which runs on it, I would bet that Joe Sixpack will choose to continue commuting with whatever fuel is available. Labeled "roundly inappropriate" by forum pundits or not.

Since almost half the US population has no access to NG at home, and almost the entire population has no access to on the road NG refueling, they won't have that choice. Add in the aforementioned inefficiency of burning NG in an ICE, and the huge costs involved in building out an infrastructure, and it's pretty obvious why NG for personal transportation is a poor idea.

Even if we were to build out an NG infrastructure it would be a temporary solution. Any fossil fuel is a temporary solution. I would rather seen NG used to create hydrogen and then build out that infrastructure for the short term including fuel cell cars, then hope for a water-to-hydrogen technical breakthrough in the long-term.
