Another Biodiesel Advance, From Japan
Any vegetable oil can become fuel, but not until its fatty acids are converted to chemical compounds known as esters. Currently the acids used to convert the fatty acids are prohibitively expensive.Michikazu Hara, of the Tokyo Institute of Technology in Yokohama, Japan, and his colleagues have used common, inexpensive sugars to form a recyclable solid acid that does the job on the cheap. Their research is reported in last week's issue of the journal Nature.
"We estimate the cost of the catalyst to be one-tenth to one-fiftieth that of conventional catalysts," Hara said.
The breakthrough could provide cost savings on a massive scale, he said, because the technique could fairly easily make the transition from the lab to the refinery—if interest warrants.
"We have developed this material for large-scale chemical production," Hara said. "Unfortunately, interest in biodiesel in Japan is not higher than in the U.S. and Europe."

Wired: "Why $5 Gas Is Good For America"
At the climax of his book Twilight in the Desert, Houston investment banker and energy guru Matthew Simmons describes a visit to the world's most powerful oil company, Saudi Aramco, in Dhahran. Simmons listens in horror as a senior manager reveals the kingdom's darkest secret. The old ways no longer suffice. To keep their aging wells productive, the Saudis now rely upon one information age prop after another: advanced analysis of rock cores, 3-D seismic imagery, software for diagnosing underground oil flows - all integrated using something called fuzzy logic. Fuzzy logic? The Aramco man tries to explain the science of complex systems and partial information, but Simmons hears only tidings of a bleak future. Obviously, the end of energy as we know it is nigh.Simmons' techno-cluelessness would be funny - calling Jed Clampett with his 12-gauge! - if he weren't the spearhead of a whole hand-wringing school of petro-pessimism. The oil fields are running dry, the gas gauge is on empty, the American way of life is doomed - these ideas bob like plastic shark fins on the storm surge of current oil prices. But the history of energy innovation suggests something very different - and a lot less dire.
On The Effect Of Zombies On The Power Grid
Does The Hockey Stick Matter?
The Lithium Economy
I don't believe in fuel cells for portable power. I think it's a dumb idea. The good news is: they burn hydrogen with oxygen to produce electricity, and only water vapor is the byproduct. The bad news is: you have to deal with molecular hydrogen gas, and that's what's stymieing the research and in my opinion is always going to stymie the research.So what's to replace it? Batteries!That's why I don't work on fuel cells. Where's the infrastructure? Where are we going to get hydrogen from? Hydrogen is a molecule, it's H2. To break it apart, to get H+, you've got to go from H2 to H, and that covalent bond is very strong. To break that bond you have to catalyze the reaction, and guess what the catalyst is? It's noble metals -- platinum and palladium. Have you seen the price of platinum? Lithium [for lithium ion batteries] is expensive. But it's not like platinum. Lithium right now is probably $40 a pound. Platinum is $500 an ounce. If I could give the fuel-cell guys platinum for $40 a pound, they would be carrying me around on their shoulders until the day I die.
TR: How good can batteries get?"I want these batteries so cheap you can give them away," he says, and they'd have to be for what he wants them to do. Interesting stuff, anyway.DS: I think we could easily double [the energy capacity of] what we have right now. We have cells in the lab that, if you run the numbers for a thin-film cell of reasonable size, you end up with two to three times current lithium ion [batteries].
But there's more. The fantasy of all fantasies is chromium. If we could stabilize chromium [as a material for battery cathodes] and I could...give you a battery with 600–700 watts per kilogram [of energy capacity] with reasonable drain rate, that says good-bye hydrogen economy.

OPEC: Oil Demand Starts Growing Again
Despite marginal revisions to its global growth forecasts, OPEC said "we were right to refute" talk of "demand destruction" fueled by U.S. hurricanes and surging crude and product prices.There is, it added, "vigorous preliminary growth data from developing countries, a brighter outlook for the world economy particularly for the U.S.A and OECD Pacific countries, and a rebound in Chinese apparent demand."
On the last point, "there are indications that Chinese demand has started to pick up."
It cited Chinese government orders to rebuild oil stockpiles from as low as three days' cover to at least 10-15 days. The end of a products export rebate and a likely surge in imports ahead of the Chinese New Year likely herald a return to strong Chinese growth, it added.

New IEA Report
Branson: All Boarding For Cellulosic Ethanol
“We are looking for alternative fuel sources. We are going to start building cellulosic ethanol plants (to make) fuel that is derived from the waste product of the plant,” he told Reuters in an interview in the oil-rich United Arab Emirates.Essentially, it's a "I'm sick and tired of paying high jet fuel prices and I'm not gonna take it anymore" PR move. Is cellulosic ethanol cost-effective? Stay tuned...“It is 100 percent environmentally friendly and I believe it’s the future of fuel, and over the next 20 or 30 years I think it actually will replace the conventional fuel that you get out of the ground.”
Branson did not say where Virgin would build his factories or how economically viable cellulosic ethanol would prove. “We are in the early days,” he admitted.

The Peak Oil Contrarian: Another Day In The Desert
Another Day is the most widely read piece of research ever put out by independent Calgary energy consultancy Ross Smith Energy Group Ltd. and the paper supports what many technical minds had suspected: That Twilight's attempt to assess the capacity of Saudi Arabia's oil reservoirs is flawed.Simmons responds, with an anecdote:"The book posits a crisis where in our opinion none exists," wrote Jim Jarrell, president of Ross Smith and author of Another Day. "We believe Twilight attempts to turn benign technical matters into crisis-level evidence."
...
"I got a comfortable feeling that [Saudi Arabia has] an unprecedented record of reservoir operations and management," he said. In his paper, he concluded that Saudi reserves are likely not overstated, that production is unlikely to collapse and that the exploration potential of the kingdom is probably better than anywhere else on Earth.
"He said: 'I'm the dean of the petroleum department at the University of Texas and I've got to tell you your book was stunning. I think it's the best textbook anybody's ever done on reservoir mechanics.' ..... I've had too many responses like that to have any doubt."Ross Smith's homepage has a link to a related review (PDF) of their report appearing in the Financial Times. Well: with both sides quite certain the other's wrong, it'll be an interesting read, no doubt....Mr. Simmons said Mr. Jarrell puts too much faith in things the Saudis have said about their oil fields, suggesting that the odds of a collapse are far higher than the kingdom's assertion that it can notably boost production rates.

Godwin's Law No Longer Applies
... why threaten to veto a law that would simply codify what Bush alleges is already the current policy? If "we do not torture," how to account for the hundreds and hundreds of cases of abuse and torture by U.S. troops, documented by the government itself? If "we do not torture," why the memos that expanded exponentially the lee-way given to the military to abuse detainees in order to get intelligence? The president's only defense against being a liar is that he is defining "torture" in such a way that no other reasonable person on the planet, apart from Bush's own torture apologists (and they are now down to one who will say so publicly), would agree. The press must now ask the president: does he regard the repeated, forcible near-drowning of detainees to be torture? Does he believe that tying naked detainees up and leaving them outside all night to die of hypothermia is "torture"? Does he believe that beating the legs of a detainee until they are pulp and he dies is torture? Does he believe that beating detainees till they die is torture? Does he believe that using someone's religious faith against them in interrogations is "cruel, inhumane and degrading" treatment and thereby illegal? What is his definition of torture?For the guy who showed up here the other day and remarked that Bush was a "conservative", the definition of that word must mean he holds to the set of values that Torquemada held dear. They can't afford for this to become any more public knowledge than already is the case, and so the Administration is damned interested in investigating and punishing those who've leaked it; public scrutiny of what goes on in the dungeons of faraway countries could have real implications.
At this point, surely, there is no longer any comprehensible defense of Bush policy on these matters.
The desperation grows in the White House, and among its legion defenders. Peggy Noonan, who once upon a time used to write speeches for the likes of Reagan, is now reduced to anxious self-pity, an apocalyptic self-doubt catalyzing her wheels-coming-off-the-trolley analogy that practically begs for a strongman dictator to come and right the troubles of a rudderless nation. Her discomfort with actual liberty, i.e., the idea that no central planner is running things, shows to me that she hasn't got the slightest of clues about how free societies actually work. In fact, she has been one of its chiefest enemies for a while now. In her column, "Why Are Our Politicians So Full Of Themselves", she asks of Barack Obama why he's such an impressive gasbag, while scarcely noting that Bush is so full of himself that he's has lied about damn near everything he ever said while in office: the weapons of mass destruction, the threat Iraq posed to the United States, and now, the existence, to our eternal shame, of an American gulag with torture as one of its underpinnings. Godwin's Law, the idea that the first online participant to start making Nazi analogies loses any discussion, ceases to apply if, in fact, the action is something that Nazis would have actually done.
Update: The one thing that really set me off was the one thing I couldn't find until I dug it out of yesterday's browser cache, and that is this Norman Podhoretz howler of a column at Commentary, entitled "Who Is Lying About Iraq?" One of the most appalling attempts I've seen yet to keep Bush's string of big lies going; if there were a Hermann Goehring Propaganda Award, he'd take it with this piece in a heartbeat. How do these people sleep at night?
Sydney Morning Herald On Green Investments
The recent bidding war over the renewable energy group Southern Hydro and the premium AGL was prepared to pay to knock out the competition were clear signs of the appeal of well-run, income-producing alternative energy stocks.AGL paid $1.43 billion for the group, which owns 11 hydro power stations in NSW and Victoria as well as Australia's largest wind farm in South Australia, outbidding Babcock & Brown and Origin Energy.
At the smaller end of the market, Australian Ethanol, which produces ethanol from grains and sugar, leapt 14c cents to 47c last month on news that car manufacturers had accepted the use of ethanol-blended fuel.
Kevin Bullis On Small Nuclear
On the downside, building small reactors means losing out on the economy of scale that has driven a trend toward bigger and bigger reactors, says Wade. He hopes to make up for this by creating ways to mass-produce the reactors in modules that can be quickly assembled on site.

Floating Windmills At Sea
Focus Fusion
A distinct lack of scholarly footnotes, parenthetical rejections by the DOE, and the prominence of fundraising on their website leads to immediate questions as to the true nature of the endeavor; are they trying to build a reactor, or are they trying to fleece the public? Hyperbolic press releases add to my concerns.

Arriving Early To The Party
Peter Huber On EROEI
The economic value of energy just doesn't depend very strongly on raw energy content as conventionally measured in British thermal units. Instead it's determined mainly by the distance between the BTUs and where you need them, and how densely the BTUs are packed into pounds of stuff you've got to move, and by the quality of the technology at hand to move, concentrate, refine and burn those BTUs, and by how your neighbors feel about carbon, uranium and windmills. In this entropic universe we occupy, the production of one unit of high-grade energy always requires more than one unit of low-grade energy at the outset. There are no exceptions. Put another way, Eroei--a sophomoric form of thermodynamic accounting--is always negative and always irrelevant. "Matter-energy" constraints count for nothing. The "monetary culture" still rules.
