US says won’t allow Iran to shut key Gulf oil route
MANAMA - The commander of the US navy’s Fifth Fleet warned on Monday that the United States will not allow Iran to shut the Strait of Hormuz, a key oil supply route in the Gulf.“They will not close it... They will not be allowed to close it,” Vice-Admiral Kevin J. Cosgriff said at a press conference in Bahrain, where the Fifth Fleet is based.
U.S. helped Iraqis on oil contracts
A group of American advisers led by a small State Department team played an integral part in drawing up contracts between the Iraqi government and five major Western oil companies to develop some of the largest fields in Iraq, U.S. officials say.The disclosure, on the eve of the contracts' announcement, is the first confirmation of such direct Bush administration involvement and is sure to stoke criticism of the deals. On Monday, Iraq invited bids for the development of its largest oil field. The country has prequalified 41 foreign firms.
High fuel prices reshaping airline industry: Milton
MONTREAL — — Record-high oil prices are hurting travel demand and reshaping the world's airline industry, with discount carriers suffering more than most, says Robert Milton, chief executive officer of Air Canada's parent company."This one is a truly global issue, and I think you're going to see a lot of airlines disappear," Mr. Milton said Monday after ACE Aviation Holdings Inc.'s annual meeting in Montreal.
"The ones who are going to really have a problem are the airlines that have been trying to sell a low-fare proposition."
Majors say speculators not to blame for oil price
MADRID (Reuters) - The heads of some of the world's biggest oil companies countered on Monday OPEC claims that speculators were driving high oil prices, blaming instead a dearth of new supplies.The chief executives of Royal Dutch Shell Plc, BP Plc and Spain's Repsol YPF told the oil industry's biggest gathering in three years that restrictions on where they can invest and high taxes meant they could not help boost supplies as much as they might.
Saudis' Oil Meeting Produces Few Results
A more significant outcome of the meeting was the indication that Saudi Arabia believes oil prices have climbed too far. Yet no indication was given as to how far crude might have to fall for Saudi Arabia to reverse its current accommodating stance. There can be little doubt that Riyadh and OPEC's evaluation of what constitutes a fair price for oil has risen dramatically in line with rising prices.
Corn harvest shortage will hike food prices
DES MOINES, Iowa - Farmers will harvest nearly 9 percent fewer acres of corn this year than last year, in part because of Midwest flooding which has damaged a portion of the crop, the government reported Monday.The result likely will be continued high corn prices, which likely will drive up some food prices.
The infrastructure crisis - it'll be the survival of the fastest
We are facing an infrastructure crisis. In North America and Europe the bones, muscles and nerves that keep us in motion are not keeping up with the demands we place on them.The infrastructure crisis is a mega-trend - one that will sweep all of us along in its path. You can either be carried along in its path or take decisive actions for your benefit.
Today's companies built their business models - customers, retail networks, manufacturing, sourcing and logistics - over the past 40 years. When these business models were being built logistics costs steadily declined as transportation efficiencies increased and the cost of fuel declined in real terms. That is why people built big plants and distribution centres in remote locations. It is why China is viable as a sourcing centre for many companies whose markets are in North America and Europe.
Part one: America is falling apart - Growing backlog of repairs to roads, sewers and other basics threatens economy, livability
Remember that bridge that collapsed in Minneapolis last summer? More than one-quarter of U.S. bridges -- including one-quarter of Oregon's -- are structurally deficient or functionally obsolete.We need to spend $250 billion to fix our aging water pipes. And our telecommunications system is far slower than the rest of the world's lightning-fast broadband.
"We're basically sliding toward Third World status," said Rep. Peter DeFazio, D-Ore. "It's pathetic."
Kansas Department of Transportation Secretary Deb Miller wants people to call members of the state's congressional delegation and urge them to steer some money into the federal Highway Trust Fund.No doubt transportation secretaries in 49 other states have made similar pleas to their constituents.
It appears Congress has been playing fast and loose with the fund — borrowing money from it and forgetting to pay it back. The neglected loans include one of $8 billion dollars in 1998 and others for the 9-11 recovery effort in New York City and the Hurricane Katrina recovery effort in New Orleans.
Report: U.S. 'preparing the battlefield' in Iran
WASHINGTON (CNN) -- The Bush administration has launched a "significant escalation" of covert operations in Iran, sending U.S. commandos to spy on the country's nuclear facilities and undermine the Islamic republic's government, journalist Seymour Hersh said Sunday.
Oil disquiet on the Western front
North American media, Andrew Nikiforuk says, take for granted how much oil undermines democracy, powers our food system, feeds our drug-addled medical industry and concentrates our cities like bovine feedlots.
To China, stability may be more valuable than oil profit
BEIJING: The dramatic decision by China to raise fuel prices by more than 15 percent last month might seem to suggest that Beijing is shifting into a higher gear in its drive toward raising the prices of domestic resources to global norms.Don't be fooled, analysts say. The sudden increase does not mean a sea change in Chinese policy although it might embolden Beijing to take small but more frequent steps in the future, if the fallout from fuel price increases is contained.
Energy's easiest fix: Use less
NEW YORK (CNNMoney.com) -- Want to help the country save a quick million barrels of oil a day? Drive 5% less. Slow down. Inflate your tires.Those three steps would reduce U.S. oil consumption by 1.3 million barrels a day immediately, according to the Alliance to Save Energy, a conservation group running an efficiency campaign backed not only by environmental groups but also the auto and oil industries.
As Gas Prices Rise, Teenagers’ Cruising Declines
SCHAUMBURG, Ill. — For car-loving American teenagers, this is turning out to be the summer the cruising died.Kevin Ballschmiede, 16, pined for his 1999 Dodge Ram — “my pride and joy” — the other night as he hung out in a parking lot in this town outside Chicago. Given that filling the 26-gallon tank can now cost more than $100, he had left it at home and caught a ride.
From coast to coast, American teenagers appear to be driving less this summer. Police officers who keep watch on weekend cruising zones say fewer youths are spending their time driving around in circles, with more of them hanging out in parking lots, malls or movie theaters.
Britain goes slow as trains, planes and ships cut fuel costs
The soaring cost of oil has led to the slowing of vehicles of almost every type in Britain, from planes to trains, ferries, merchant vessels, buses and private cars.Pilots and ships' captains have been ordered to go slow, train drivers have been asked to switch off engines and coast downhill and bus companies are training staff to drive more smoothly in order to cut costs.
Nepal: Transport workers seize, distribute 24,000 liters diesel
KATHMANDU - Transportation workers of Butwal, Rupandehi district seized two tankers from the regional office of Nepal Oil Corporation (NOC) at Bhairahawa and distributed it to entrepreneurs at the existing rate on Sunday.They resorted to such an action saying that shortage of petroleum goods was creating hand-to-mouth problem.
Bill McKibben: When Words Fail
I ALMOST NEVER write about writing — in my aesthetic, the writing should disappear, the thought linger. But the longer I’ve spent working on global warming—the greatest challenge humans have ever faced—the more I’ve come to see it as essentially a literary problem. A technological and scientific challenge, yes; an economic quandary, yes; a political dilemma, surely. But centrally? A crisis in metaphor, in analogy, in understanding. We haven’t come up with words big enough to communicate the magnitude of what we’re doing. How do you say: the world you know today, the world you were born into, the world that has remained essentially the same for all of human civilization, that has birthed every play and poem and novel and essay, every painting and photograph, every invention and economy, every spiritual system (and every turn of phrase) is about to be . . . something so different? Somehow “global warming” barely hints at it. The same goes for any of the other locutions, including “climate chaos.” And if we do come up with adequate words in one culture, they won’t necessarily translate into all the other languages whose speakers must collaborate to somehow solve this problem.
Cries in the Dark (Roscoe Bartlett, James Woolsey, Andy Karsner, Robert Hirsch)
How serious is America's energy crisis? These four voices want to make sure policymakers don't dismiss it -- again.(This is one of many articles in a special Energy Section. There are also articles on nuclear, solar, natural gas, and lots more.)The oil shock of 1973 came and went. So did the panic after the Iranian revolution six years later, when oil prices shot to record highs. Gone, too, is the brief flurry of fear that followed Iraq's invasion of Kuwait in 1990.
After each, voices in Washington that cried out for big changes in U.S. energy policy were slowly drowned out. James Schlesinger, the first U.S. energy secretary, has said for decades that when it comes to energy policy, the U.S. toggles between complacency and panic.
Will it be different this time around?
Alberta oil finds allies in U.S.
Alberta found some friends Sunday at the western U.S. governors' meeting, when a pair of nearby lawmakers defended the oilsands and suggested Canada continue to ramp up its output in the face of environmental concerns."We have an energy crisis in this county and maybe the only reliable trading partner we have in this country is my neighbours, my friends in Alberta," said Montana Gov. Brian Schweitzer, a Democrat.
How did we get into this situation after a 100-year span in which the prevailing economy was cheap energy, slow increases and even steady pricing, with general confidence that it would remain so?Some experts, like specialized geographer Robert Kaufmann of Boston University, call the past 150 years the "Petroleum Age," and he says it is beginning to draw to a close.
The fuller body of evidence points to a finite supply of oil, declining production and reserves from the traditional and easiest sources in the U.S., and increasingly expensive prices as hard-to-get reserves like deep water, tar sands and oil shale are tapped.
If speculators aren’t at fault, why have oil prices spiked so high? Fundamental reasons aren’t hard to find. Between 2000 and 2007, world demand for petroleum rose by nearly nine million barrels a day, but OPEC has been consistently unable, or unwilling, to significantly increase supply, and production by non-OPEC members has risen by just four million barrels a day. The prospect of military action against Iran, which would disrupt global supply, seems greater than it did a few years ago. And the plunging value of the dollar has meant that the cost of oil has jumped more in the U.S. in the past year than it has in countries with healthier currencies.But there’s also something else at work, which the oil guru Daniel Yergin calls a “shortage psychology.” The price of oil—more than that of many other commodities—isn’t based solely on current supply and demand. It’s also based on people’s expectations about future supply and demand, because those expectations determine whether it makes sense for oil producers to sell their oil now or leave it in the ground and sell it later.
Credit Card Fees at the Pump are a 'Hidden Tax' on Consumers
Consumers are feeling pain at the pump from gas prices topping $4 a gallon but it's not just gas they're paying for. They're dishing out "invisible" extra fees for using a credit or debit card when they gas up.Interchange fees, the payments credit card companies and banks charge retailers for processing transactions made with plastic, constitute "a $50 billion fee on consumers," said retailer Mitch Goldstone, owner of the 30 Minute Photos photo shop.
New street crime: Thieves lift manhole covers
Cities and counties are battling manhole-cover thefts, a crime spree that police tie to the weak economy.Hundreds of 200-pound covers have disappeared in three months in California, Michigan, Pennsylvania, Massachusetts and Georgia as scrap metal prices pop up.
"It's a sign of the times," says Sgt. Jay Baker of the Cherokee County Sheriff's Office in Georgia, where 28 manhole covers disappeared in April and May. "When the economy gets bad, people start stealing iron."
New set of Noble prizes for energy in offing
Mumbai, June 30: The descendants of Alfred Noble, are planning to come up with a new set of Noble awards but with a difference.Dr Michael Noble, the great grand nephew of Alfred Noble, who was here for a conference on "Responsibility To The Future" organised by Strategic Foresight Group, said that Noble Charitable Trust would institute an award for great work done in alternative energy.
Oil prices surge to record heights near $144
LONDON (AFP) - Oil prices hit record high points close to 144 dollars per barrel on Monday as the dollar fell further and amid a conference and protests staged in response to soaring crude, analysts said.Brent North Sea crude reached a historic peak of 143.91 dollars a barrel and New York light sweet crude struck an all-time high of 143.67 dollars.
"The market remains well supported by the broad weakness in the dollar, ever increasing investor interest in commodities, persistent supply disruptions and geopolitical tensions," Sucden analyst Andrey Kryuchenkov said on Monday.
Former President Bush energy adviser says oil is running out
The era of globalisation is over and rocketing energy prices mean the world is poised for the re-emergence of regional economies based on locally produced goods and services, according to a former energy adviser to President Bush and the pioneer of the “peak oil” theory.Matt Simmons, chief executive of Simmons & Company, a Houston energy consultancy, said that global oil production had peaked in 2005 and was set for a steep decline from present levels of about 85 million barrels per day. “By 2015, I think we would be lucky to be producing 60 million barrels and we should worry about producing only 40 million,” he told The Times.
Today's suburbs, tomorrow's slums?
According to some doomsday scenarios, spiking gas prices could turn the cul-de-sacs and two-car garages that surround North America's cities - built over the past 60 years and designed for the convenience of people with cars - into tomorrow's slums.The predictions for the most part come from subscribers to the theory of "peak oil," which holds that crude prices will shoot permanently upward as global demand outstrips dwindling supply, ruining the economy. But their predictions are getting a second look now, as suburbanites, especially in the United States, grumble at the rising price of a fill-up.
Crude today is dirt cheap: Matthew Simmons
There are projections that oil may touch $200 a barrel by year-end. Do you think we are heading towards such a situation?There are so many whacky theories swirling around the world on why oil prices stunned everyone. Speculators are mostly betting that crude will soon crash, so I suspect this group of investors is net short, and if they are banned from speculating, oil prices will jump higher.
The oddest question is the one seldom asked: why did 99% of the presumptive oil experts have their eyes shut as this earth-shattering event played out, and why the busload of sleepers are still so confused?
Russian oil exports fell 5.3% to 757mln bbl in Jan.-May
MOSCOW (RIA Novosti) - Russia's crude oil exports fell by an estimated 5.3%, year-on-year, in January-May 2008 to 103.3 million metric tons (757 million barrels), the Economic Development Ministry said Monday on its web site.The decline was due to lower crude output and increased supplies to domestic refiners, the ministry said.
Giant Saudi field is key to boosting oil output
KHURAIS OIL FIELD, Saudi Arabia - This massive oil field surrounded by the desolate sands of Saudi Arabia's vast eastern desert feels like the middle of nowhere.But what happens over the next year at Khurais, one of Saudi Arabia's last undeveloped giant oil fields, could hold the key to what drivers will pay at the pump for years to come.
Canada Oil Sands Need Minimum Price $70 a Barrel, Statoil Says
June 30 (Bloomberg) -- Canadian oil sand deposits require crude prices of at least $70 a barrel to cover capital and operating expenses and provide an acceptable rate of return, a StatoilHydro ASA executive said.
BP chief blames inadequate supply for soaring oil prices
MADRID (Xinhua) -- The chief executive of the energy giant BP said on Monday that soaring oil prices are a result of an inadequate supply rather than speculation."These prices are a signal that is telling us that supply is not responding adequately to rising demand," Tony Hayward told delegates at the 19th World Petroleum Congress (WPC) being held in Madrid.
He suggested politics rather than geology is the reason behind the supply shortage.
"The problems are above ground not below it," Hayward said.
Iraqi notice on oil does not include contracts
BAGHDAD - The Iraqi government opened six oil fields to international bidding Monday as the nation attempts to boost daily production by 60 percent.
Oil a shaky crutch for Iran's Ahmadinejad - While some are prospering, inflation eroding purchasing power of many
TEHRAN - Faced with rapid inflation and growing international concern about his country's nuclear ambitions, Iranian President Mahmoud Ahmadinejad is relying on huge increases in oil and gas revenue to insulate his government from internal and external pressures.
A couple of months ago, Yoko Olsgaard was weighing offers for two project management positions. One was in Fremont, about 27 miles from her home in Oakland's Redwood Heights neighborhood. The other, which paid 10 percent less, was with Kaiser Permanente in Emeryville, about 7 miles away.She ended up choosing the lower-paying Kaiser job. The main reason? The high price of putting gas in her 2001 Toyota Camry.
Fuel costs take toll on farmers' bottom lines
Ghiggeri & Stonebarger Farms used to spend $100 to $200 to grow an acre of the Brentwood sweet corn sold throughout Bay Area supermarkets and prized by chefs at some of the Bay Area's top-rated eateries.But this year's record fuel and fertilizer prices have driven those costs sky-high — up 30 percent to 50 percent from last year — for G&S and other local farmers.
Korea is now mired in a seemingly endless beef brawl, but the rest of the world is wrestling with skyrocketing oil prices. So it is only natural ― if quite belated ― for the government to come up with a contingency conservation program. Its contents and underlying assumptions show, however, that Seoul still doesn't seem to be fully aware of the dire situation facing this country.
What’s Really Fueling Those Sky-High Oil Prices - There are lots of theories; most of them are right
Ask any number of experts about what’s causing the current run-up in oil prices, now around $140 a barrel, and you’re likely to get several different answers.
The positive side of high oil price
Peak oil or freak oil? The current oil shock, with Nymex crude touching $142 on Friday, has as much to do with bad luck as geology. And, as usual with luck, man has largely made his own.The central theme of this decade's bull market in crude is little different from previous oil shocks: a change in expectations about future supplies. In other words, many think we have enough oil today but might not tomorrow.
U.S. Power Agency Warns High Electricity Prices Could Plague America ‘For Years to Come’
Citing high commodity prices for natural gas and coal, which were the fuel sources for 18% and 50%, respectively, of U.S. electricity generation in 2007, the Federal Energy Regulatory Commission (FERC) said this “may be the beginning of significantly higher power prices that will last for years to come.” The agency didn’t say exactly how high it thinks prices could rise, but EnergyTechStocks.com has learned that one major U.S. electric utility is now assuming in its internal forecasts that power prices in its region will double within five years or less.
Solar and Wind Will Drive Natural Gas Up
A second important market likely to strengthen in near future years is electric power generation. That market is turning strongly away from coal in the U.S. and Europe and toward alternatives like solar and wind which are non-base load sources, meaning they work during some days and some hours a lot better than others. When they don’t work, the generating plants must have “peaking capacity” to bring them quickly up to nameplate capacity. Natural gas is the way to obtain short term bursts of generating capacity.
Four killed in Niger Delta attacks
Lagos - Two unidentified gunmen and two civilians were killed, one of them beheaded, in two separate attacks on Saturday in southern Nigeria's oil-rich Bonny Island, a military spokesperson said on Monday.
Shell says no weekend attack on Nigeria oil sites
ABUJA (Reuters) - Royal Dutch Shell said on Monday there were no attacks on its oil flow stations in Nigeria over the weekend following local media reports of clashes with militants near its facilities at Bonny.
High helium prices limit gas balloons as sport
"Price is just about to drive gas ballooning extinct in this country," said Andy Cayton, an avid gas balloonist and retired army helicopter pilot who runs balloon rides in Georgia.The price for a full tank of gasoline for cars might be exorbitant these days, but filling up a helium-filled gas balloon could cost over $12,000. And that's just the gas; buying a gas balloon itself can cost about $30,000.
Two to three years ago, the cost to fill a helium balloon of the same size was about $3,000.
Few are ready to talk about the carrying capacity of Earth and whether we are exceeding it. Perhaps the time has come to realize that Earth is close to being stressed beyond its ability to support the people inhabiting it. It is not just the food we grow, but the damage we are causing to the land by over-farming, the addition of pollutants to the atmosphere bringing on rapid climate change, and the now-generation approach that we must have it all. We have not grasped the concept of sustainability.
Imagine the day when your vehicle’s odometer becomes a tax meter — the more you drive, the more you pay in taxes.When you do drive, you’ll be greeted by more toll stations. And when you stop, you’ll be greeted by more parking meters. Along the way you’ll notice roofs with solar panels, yards with vegetable gardens, construction crews building bike paths instead of roads, and perhaps even large warehouses stuffed with massive amounts of food to deal with an energy emergency that hovers on the horizon.
Speculation and the Price of Oil
The main problem is that the market for oil has been distorted by very deep interventions. The cure for the high price of oil is to liberate the market. Here is what is needed:1. Install toll charges on all crowded streets and highways just high enough to eliminate the traffic congestion. The tolls would be payable with electronic devices in cars, and only apply to places and times that would otherwise be congested.
2. Taxes on fuel would be replaced with pollution charges. That would require the economy-wide installation of remote sensors that measure the pollution as cars drive by.
Australia: Will smaller lot sizes have a renaissance?
Could this mean that smaller holdings might have a renaissance as increasing energy costs force a return towards a way of life that we once knew? Will the era of cheap energy be just a ‘blip’ in history?
China's Hu says 'time is limited' in curbing climate change
BEIJING (AFP) - Chinese President Hu Jintao urged renewed efforts to curb global warming on Saturday, stressing "time is limited" in finding efficient solutions to the problem, state media reported."How we cope with climate change is related to the country's economic development and people's practical benefits. It's in line with the country's basic interests," Hu said according to the official Xinhua news agency.
Eco progress to continue despite economic woes: IPCC chief

“Railways handle 32% of Swiss freight traffic and 16% of passenger traffic, but they use only 3% of the total energy required for all transportation.”

89% of the electricity came from SBB owned hydroelectric plants and the rest from the Swiss grid (60% hydro, 40% nuclear).
Best Hopes for Electrified Rail,
Alan
Alan Drake is the man with a plan--to "Make things not as bad as they would otherwise have been." How's that for a winning campaign slogan? All we can do is to be ready with a credible plan when the rest of the country realizes what Alan realized a long time ago, that the path to the future is on an electrified rail system.
I suggest that you work toward setting up speaking engagements for Alan in your local community (I am doing precisely that Dallas). If nothing else, stress a four letter word, J-O-B-S.
What I would be interested in is some type of rail connecting small rural farming communities. At one time all of these small towns had a rail trunk; the old rail station in my town is used as a Kiwanis meeting center. Many of these rail lines were removed when the interstates came. My thinking is that these rail systems could be connected to local hubs which would be then tied to the main system. Should be a lot more efficient than trucking and personal transportation, and it might revitalize these small towns for futre centers of locally produced agriculture. Any one have any plans for something like this?

Therein lies the problem; pitting the campaign slogan "Make things not as bad as they would otherwise have been" vs. "You can have it all just the way it was before," guess which one will win.
Unfortunately, truth doesn't get you elected. Doesn't get your project selected either.
He could always go with Jimmy Carter's "Eat Your Broccoli, America!" speech. Though it didn't seem to work too well for Mr. Carter.
But yeah, "Making things not as bad" could include lots of things, in no particular order:
etc. ...
The 31 billion Swiss franc TransAlp and related projects should increase passenger modal share for rail (240 kph trains) but the Swiss are planning on an 80% modal share for rail freight vs. heavy trucking.
Much of the portion of the 31 billion that was borrowed (much was "pay as you go" with taxes) will be repaid with new tolls on trucks after two major new rail tunnels are opened.
One tunnel will provide a level, straight rail path from Zurich to Milan using 58 km, 20 km and 10 km tunnels (from memory) for up to 300 trains/day and trains up to 1.5 km long and at speeds to 240 kph (150 mph).
SBB uses 16.7 Hz electricity (1/3rd of 50 Hz so they can convert from grid if need be, but they prefer making their own power in their own hydroelectric plants).
Best Hopes for SBB,
Alan
What's the advantage of using a different frequency?
It allows you to use motors with fewer poles (or get greater torque from a given AC motor) AFAIK. I would like to know more.
Also some long distance transmission advantages.
Amtrak's NorthEast Corridor operates at 25 Hz south of New York City to Washington DC. With modern electric locos, Hz is no longer an issue. They convert single phase AC from wire to DC and then 3 phase AC
Hopes that helps,
Alan
(from Wikipedia)
The lower the frequency the lower the motor speed, and the higher the torque available. Also easier gearing and better power factor in both the motor and the transformers.
Also, in general (with lots of exceptions):
DC motors > AC motors in cost
Synchronous AC motors > Induction AC motors in cost
Cheapest motors in big sizes around are squirrel cage induction motors. Three phase types are self-starting and can act as generators, for regenerative braking.
AFAIK, most traction motors used to be series wound DC, but now tend to be wound-rotor induction. Wikipedia notes the TGV is a synchronous AC, though.
Simple schematic diagram of a modern electric locomotive

FYI for those curious,
Alan
Neat !
BTW,
One time you mentioned a 40 pole motor was the most you knew of in locomotive applications.
I told one of my HVAC/R instructors about that (he's a retired nuke engineer) and he expressed an interest in seeing a schematic of that.
Have you come across such a thing ?
I poked around google a bit.
I think it was hydroelectric. Matches optimum RPM for the turbine with the generator by increasing the # of poles.
2 pole 50 Hz = 3000 rpm
2 pole 60 Hz = 3600 rpm
40 pole 60 Hz = 180 rpm
40 pole 50 Hz = 150 rpm
www.andritz.com/hydro-media-media-center-hydro_news_2003_05_en_1_.pdf
1.3 Mb pdf
40 pole is not the limit of those in use, I think I once heard of a 62 rpm 116 pole hydroelectric generator. Not economic today (and rewinding it would be "problematic").

We need rail, but we also need restructured cities which make it possible to largely minimize the use of any transportation system, except bicycles and walking.
Best Hopes for more pedestraian zones, more compact cities, more localized goods and services, and more people who live closer to where they shop,work, and recreate.
Denver is overlaying an extensive rail and bus system on their existing sprawlapolitan area, but I fear that this will be a very inefficient approach as people will still be commuting long distances. If they don't rein in exurbia, people will be able to move even further out and still take advantage of the new rail systems.
True, but the "old Boston suburb" model (up to @ 1950) is also viable, if not perfect.
Small towns of, say, 5,000 to 20,000 population, with downtown within walking distance for healthy people. Downtown rail station that takes a certain % of the labor force to Boston every morning. Local services (plumbers, grocery stores, doctors, schoolteachers, etc.) provide employment for a majority that can walk to work near downtown. The rest commute via train and bring back the $.
In an area with more fertile soil than Massachusetts, local farmers need only take their produce a couple of miles to the local Suburban grocer or for transport to Boston via train.
Not Utopia, but sustainable IMO.
Just electrify the "T" (MBTA) !
Best Hopes for Transit Suburbia,
Alan
That's very similar to most of Nassau County (county on long island closest to NYC). A good number of people work in NYC (mostly in Manhatten), I've heard about 25% take the Long Island Rail Road, which averages 200k passengers (I'm pretty sure making it the largest commuter rail system in the country), both commuters and a great deal of recreational NYC travelers. While most towns' buisness districts aren't within walking distance, they're mostly a short drive away, many of which are clustered around the major Long Island Rail Road stations. There's also a significant pressence of inter-town busses, although I think it mostly serves low-income workers that work in nearby towns.
Here, the railroad to an extent encourages sprawl, but at the same time the NYC metropolitan area would but untenable without (not enough room for new roads, not enough area to park cars, etc) the Long Island Rail Road, Metro North, and PATH systems, and allows to be probably the densest buisness center in the world which relies moreso on public transit than driving intra city movement, and significantly relies on public transit for suburb to downtown commuting and recreation travel.
Hi, tstreet.
The Oakland task force report talks about restructuring Oakland into small neighborhoods called Urban Villages.
The report, however, is short on details on how to execute that vision in a world of high energy prices.

I know, that's why in my conversations with Jeanne Rosenmeier I encourage her Task Force to take a really hard look at disaster cleanup in a post peak world. (Jeanne saw it right away, btw; I simply had to mention it.)
The Oakland Peak Oil Report does not discuss disaster cleanup and rebuilding in a post peak world at all, which I think is a major omission. I suspect that after The Big One, we may be forced to abandon large swaths of city throughout California because we won't have the energy to rebuild.
It's also one of the reasons I am recommending that each of our counties have their own Strategic Petroleum Reserve, some portion of which would be allocated for disaster cleanup (and maybe some rebuilding but I doubt we'll have that much). In Marin County, our next job is to have peak oil fall under the disaster prep ordinances so that the disaster planners have the latitude to address peak oil. Our disaster guys are excellent; they get peak oil completely.

where will the gasoline come from? it'll come from all those cars and trucks that aren't on the road because of The Big One.
Railways handle 32% of Swiss freight traffic and 16% of passenger traffic, but they use only 3% of the total energy required for all transportation.
Hi Alan,
I went and had a look at the document you referenced...
http://mct.sbb.ch/mct/en/umweltbericht_02-03.pdf
...and found it disappointingly lightweight. All ratios, very few hard numbers. At one point the author confuses terajoules and petajoules (Page 26), at another point he confuses energy consumption and efficiency (Page 27 commentary on freight traffic trends).
Nevertheless, 3% of total transportation energy for 16% of passenger traffic (more damn ratios) looks impressive. What doesn't look impressive, oddly, is their claimed passenger transport energy consumption of about 9 kWh/100 passenger km - at least in comparison with the numbers given by David McKay in his analysis of energy needs in the UK. This study is a huge PDF, but probably worth the time needed to download it from here...
http://withouthotair.com/ look at pp. 135-140
...where he quotes a best in class for rail of 3 kWh/100 passenger km - the SBB claimed number is more like what McKay quotes for a tram system.
I'd be genuinely interested in your critical review of McKay's statistics. I'm sure he would be grateful for your feedback as well, given your more specialized sector knowledge. That PDF is a draft and he explicitly invites public input.
Returning to SBB, I'm wondering about that huge discrepancy between 3% energy usage and 16% passenger traffic/32% freight traffic, especially given their apparently low energy efficiency. I'm wondering if there might be something about the Swiss economy that distorts transport useage patterns. Export of financial services, drugs and tourism balanced by imports of food and finished goods? Unusually high per-caput air mileage? Double or null accounting for freight-miles in neighbouring countries and tourist air-miles? Unfortunately that ratio-ridden PDF doesn't have enough raw data to let me decide.

I went looking for more "meat" and, after the original quote, it was not what I was looking for.
Shipments between Germany and Italy are a very high % of Swiss freight (a majority ? looked at a table years ago ...).
The Swiss want this freight to be 1) on SBB or 2) go through Austria (or France) and NOT on Swiss roads anymore.
I have a very high priority task at hand, but after that I will look at the report.
Best Hopes,
Alan

Hoarding Nations Drive Food Costs Ever Higher
This is the same phenomenon that we (Khebab/Brown) have been writing about regarding energy, the Export Land Model (ELM), which is the tendency for oil exporters to only export oil after domestic consumption is satisfied. It is discussed in the following paper.
For food, we could call it FELM--Food Export Land Model. I suspect that in future years a lot of world trade will consist of trade between food and energy exporters. It is decidedly not a good time to be both a net food and net energy importer. In effect, food and energy prices are being set at the margin, as food and energy importers bid for the declining volume of food and energy supplies that make it into the export market.

A quantitative assessment of future net oil exports by the top five net oil exporters (January, 2008)
Food consumption increases with increased posperity in the sense that more grain is channeled through meat. But, whereas is seems unlikely that conventional oil will see a large increase in production, high food prices spur both greater land use and further yield increases so that food supply can be responsive to price.
The current tightness in carryover stocks in grains can be remedied by dropping ethanol mandates or (more immediately) putting feedlots out of business, cutting meat production. This is kind of different from oil where substitution takes more time. Rebuilding carryover stocks of grain should be the main objective in food policy.

Meat from pig and chicken "factories" (odd use of the term, the establishments are more like concentration camps, since no one can really "make" a pig) is still incredibly cheap. There is a lot of subsidy, and a lot of elasticity remaining in our food system.
