  • National drought threatens coal powered electricity

    Dwindling water reserves caused by the drought are raising concerns for the Victorian government and power companies about interruptions to coal powered generators in the Latrobe Valley, which provide about 90 per cent of the state’s electricity, says The Australian Financial Review (10/3/07, p. 4).

    Inquiry launched: The government, three generation companies and Gippsland Water have launched an inquiry to find ways of securing long-term supplies for five generators and two peaking stations. “We need to think about how me might augment our water supply well into the future," Gippsland Water chief executive John Mitchell said.

    Using reserve dam: Power companies warn they might have to "consider other arrangements" if there was no major rainfall in the next five months. Falling volumes in the Tanjil and Latrobe rivers, traditionally tapped for water to cool generators or for the plant’s boilers, have led Loy Yang Power and TRUenergy Yallourn to tap the Blue Rock Dam, which is at about 60 per cent capacity.

    Contingency plans: A spokesman for Energy Minister Peter Batchelor said the government was developing contingency plans to ensure the generators could secure water supplies. “We are consulting closely with the generators to review needs and secure required water supplies,” he said.

    No immediate threat: A TRUenergy spokeswoman said: “It is the first time we have had a major drought in Gippsland.” "There is no immediate threat to power generation but we are taking a cautious approach by engaging with government well in advance of any impact."

  • Unionists put their weight behind clean coal technology

    Mr Combet said if the Federal Government was serious about climate change it would have done more sooner. "We’re going to stand up for coal industry jobs but we’ve got to have a progressive policy on climate change," Mr Combet said.

    "Part of that is to encourage the mining companies, who are making big profits out of coal exports, to spend a lot, lot more on clean coal technology research."

  • Lizard brain fools SUV drivers

    Ford had intended to split the assembly line at the Michigan Truck Plant between the Expedition and the Ford F-150 pickup.   But, when the first flood of orders started coming in for the Expedition, the factory was entirely given over to S.U.V.s.   The orders kept mounting.   Assembly-line workers were put on sixty- and seventy-hour weeks.   Another night shift was added.   The plant was now running twenty-four hours a day, six days a week.   Ford executives decided to build a luxury version of the Expedition, the Lincoln Navigator.   They bolted a new grille on the Expedition, changed a few body panels, added some sound insulation, took a deep breath, and charged forty-five thousand dollars—and soon Navigators were flying out the door nearly as fast as Expeditions.   Before long, the Michigan Truck Plant was the most profitable of Ford’s fifty-three assembly plants.   By the late nineteen-nineties, it had become the most profitable factory of any industry in the world.   In 1998, the Michigan Truck Plant grossed eleven billion dollars, almost as much as McDonald’s made that year.   Profits were $3.  7 billion.   Some factory workers, with overtime, were making two hundred thousand dollars a year.   The demand for Expeditions and Navigators was so insatiable that even when a blizzard hit the Detroit region in January of 1999—burying the city in snow, paralyzing the airport, and stranding hundreds of cars on the freeway—Ford officials got on their radios and commandeered parts bound for other factories so that the Michigan Truck Plant assembly line wouldn’t slow for a moment.   The factory that had begun as just another assembly plant had become the company’s crown jewel.  

    In the history of the automotive industry, few things have been quite as unexpected as the rise of the S.U.V. Detroit is a town of engineers, and engineers like to believe that there is some connection between the success of a vehicle and its technical merits.   But the S.U.V. boom was like Apple’s bringing back the Macintosh, dressing it up in colorful plastic, and suddenly creating a new market.   It made no sense to them.   Consumers said they liked four-wheel drive.   But the overwhelming majority of consumers don’t need four-wheel drive.   S.U.V. buyers said they liked the elevated driving position.   But when, in focus groups, industry marketers probed further, they heard things that left them rolling their eyes.   As Keith Bradsher writes in "High and Mighty"—perhaps the most important book about Detroit since Ralph Nader’s "Unsafe at Any Speed"—what consumers said was "If the vehicle is up high, it’s easier to see if something is hiding underneath or lurking behind it.  " Bradsher brilliantly captures the mixture of bafflement and contempt that many auto executives feel toward the customers who buy their S.U.V.s.   Fred J. Schaafsma, a top engineer for General Motors, says, "Sport-utility owners tend to be more like ‘I wonder how people view me,’ and are more willing to trade off flexibility or functionality to get that.  " According to Bradsher, internal industry market research concluded that S.U.V.s tend to be bought by people who are insecure, vain, self-centered, and self-absorbed, who are frequently nervous about their marriages, and who lack confidence in their driving skills.   Ford’s S.U.V. designers took their cues from seeing "fashionably dressed women wearing hiking boots or even work boots while walking through expensive malls.  " Toyota’s top marketing executive in the United States, Bradsher writes, loves to tell the story of how at a focus group in Los Angeles "an elegant woman in the group said that she needed her full-sized Lexus LX 470 to drive up over the curb and onto lawns to park at large parties in Beverly Hills.  " One of Ford’s senior marketing executives was even blunter: "The only time those S.U.V.s are going to be off-road is when they miss the driveway at 3 am."

    The truth, underneath all the rationalizations, seemed to be that S.U.V. buyers thought of big, heavy vehicles as safe: they found comfort in being surrounded by so much rubber and steel.   To the engineers, of course, that didn’t make any sense, either: if consumers really wanted something that was big and heavy and comforting, they ought to buy minivans, since minivans, with their unit-body construction, do much better in accidents than S.U.V.s.   (In a thirty-five m.p.h. crash test, for instance, the driver of a Cadillac Escalade—the G.M. counterpart to the Lincoln Navigator—has a sixteen-per-cent chance of a life-threatening head injury, a twenty-per-cent chance of a life-threatening chest injury, and a thirty-five-per-cent chance of a leg injury.   The same numbers in a Ford Windstar minivan—a vehicle engineered from the ground up, as opposed to simply being bolted onto a pickup-truck frame—are, respectively, two per cent, four per cent, and one per cent.  ) But this desire for safety wasn’t a rational calculation.   It was a feeling.   Over the past decade, a number of major automakers in America have relied on the services of a French-born cultural anthropologist, G.   Clotaire Rapaille, whose speciality is getting beyond the rational—what he calls "cortex"—impressions of consumers and tapping into their deeper, "reptilian" responses.   And what Rapaille concluded from countless, intensive sessions with car buyers was that when S.U.V. buyers thought about safety they were thinking about something that reached into their deepest unconscious.   "The No.   1 feeling is that everything surrounding you should be round and soft, and should give," Rapaille told me.   "There should be air bags everywhere.   Then there’s this notion that you need to be up high.   That’s a contradiction, because the people who buy these S.U.V.s know at the cortex level that if you are high there is more chance of a rollover.   But at the reptilian level they think that if I am bigger and taller I’m safer.   You feel secure because you are higher and dominate and look down.   That you can look down is psychologically a very powerful notion.   And what was the key element of safety when you were a child? It was that your mother fed you, and there was warm liquid.   That’s why cupholders are absolutely crucial for safety.   If there is a car that has no cupholder, it is not safe.   If I can put my coffee there, if I can have my food, if everything is round, if it’s soft, and if I’m high, then I feel safe.   It’s amazing that intelligent, educated women will look at a car and the first thing they will look at is how many cupholders it has.  " During the design of Chrysler’s PT Cruiser, one of the things Rapaille learned was that car buyers felt unsafe when they thought that an outsider could easily see inside their vehicles.   So Chrysler made the back window of the PT Cruiser smaller.   Of course, making windows smaller—and thereby reducing visibility—makes driving more dangerous, not less so.   But that’s the puzzle of what has happened to the automobile world: feeling safe has become more important than actually being safe. 

  • Rising sea levels threaten PNG islanders

    ‘They must leave this year. The way things are going, I think the islands will be underwater in 15 to 20 years,’ said Tobasi.

    Next week, the 2,000 member-scientists of the Intergovernmental Panel on Climate Change (IPCC) will release their latest report, the result of six years of research.

    The 7 million citizens of 22 South Pacific island nations and territories are not expecting rosy news.

    The panel already warned in 2001 that global sea levels will rise by up to 88 centimetres by the end of the century, a development primarily caused by an increase in human-produced greenhouse gases heating the earth’s atmosphere and melting icebergs and glaciers.

    Carteret islanders, where the highest elevation is a mere 1.70 metres above current sea level, will be resettled to Bougainville within the year provided the necessary funds can be raised.

    The islanders are aware that they must hurry, because living on the islands has become almost unbearable and food is getting scarce.

    ‘They live on coconuts and fish. They used to cultivate sweet potatoes and taro in the swamps, but the floods invaded everything. There are high deposits of salt water and the soil is inappropriate now,’ said Tobasi.

    On Tuvalu, located halfway between Australia and Hawaii, vegetable fields also have long since deteriorated while fish stocks have been depleted due to coral reef bleaching.

    The highest hills found on the eight Tuvalu islands reach only 5 metres above sea level.

    The island-nation’s government has signed an agreement with New Zealand, which will accept Tuvalu’s 11,500 inhabitants when the situation becomes dangerous.

    Tuvalu’s government expects the islands to be entirely underwater within the next 50 years.

    Rain is the only source of drinking water for the 100,000 citizens of the island republic of Kiribati as shallow freshwater reservoirs are increasingly contaminated by salt due to the rising ocean level.

    Kiribati once also comprised the uninhabited islands of Tarawa and Abanuea, but in 1999 they simply went under during a tropical storm and never resurfaced.

    The doomsday clock is also ticking in the Maldives, a country of 1,200 islands off the southwestern tip of India.

    Some of the coral islands were washed over by the 2004 tsunami and remained flooded for several days, after which the waters receded once more.

    The United Nations warned that in a few years continually rising sea levels might cause up to 50 million people to lose their livelihoods and become environmental refugees.
