How to save billions of gallons of gasoline

Scientists at Lawrence Livermore National Laboratory have looked at drag-reducing devices on semi-trucks, and say they can conserve billions of gallons of fuel plus tens of billions of dollars. This not exactly rocket science.

Boat-tailed bullet (left)

The researchers estimate that trailer-skirts and boat-tails (see the pic below) could reduce drag on trucks by as much as 25%, which means they would save about 13% on their fuel bill. Apparently only a few percent of US trucks use these devices at the moment, and the researchers claim they can make up to a 19% improvement in fuel economy.

If these work that well (and are not too expensive or painful on carrying capacity), the free market will take care of this pretty quickly.

Boat tails means a tapered shape at the back of the vehicle. They are already used on bullets (and boats, obviously). There are pics of “boat-tails” on trucks below, but my favourite shot is this boat-tail on a car. A DIY masterpiece. It’s a “Pontiac Firefly (Canadian Geo Metro). The maker Darin Cosgrove says  “the Firefly squeezed out 64 miles per gallon during testing.” I can’t see mums rushing to go food shopping in it though. Boat tails on trucks are a lot less ambitious.

65% of US population are skeptical that each flood drought or heatwave is mostly “man-made”

How big is the Green B-lobby? So big, whole research projects are devoted to better ways to push propaganda onto voters. In this case, it turns out that despite an international PR blitz to unscientifically link your car exhaust to extreme floods in Bangladesh (etc and so forth), 65% of the US public just aren’t buying it. Instead the study finds that people are actually not too bad at judging whether a season was warmer than usual. (Was anyone surprised at this after 500 million years of evolution?). Disappointingly, though, for those pushing the climate propaganda, the meme that man-made global warming is to blame for all heatwaves, snowfalls, floods, hurricanes, and reckless fish is not working.

“Only 35 percent of U.S. citizens believe global warming was the main cause of the abnormally high temperatures during the winter of 2012″

This is a cruel blow to climate change activists. They had pinned their hopes on generating fear among voters by trying to associate every storm and bad-hair day to man-made global warming. But two-thirds of the public are not fooled. Even when they “personally experience” abnormally warm winters, or even hear news of a whole series of severe events, 65% of people don’t believe it was man-made.

The abnormally warm winter was just one in an ongoing series of severe weather events — including the 2010 Russian heat wave, Hurricane Sandy in 2012 and the 2013 typhoon in the Philippines — that many believed would help start convincing global warming skeptics.

“There’s been a lot of talk among climate scientists, politicians and journalists that warmer winters like this would change people’s minds,” McCright said. “That the more people are exposed to climate change, the more they’ll be convinced. This study suggests this is not the case.”

Perhaps the population is growing more propaganda-weary?

This study further finds that state-level mean temperature anomalies do not influence whether or not people attribute warmer- than-normal local winter temperatures to global warming.

Naturally, when you struggle with cause-and-effect in the climate, you also struggle with cause-and-effect in psychology. Does political orientation influence climate belief, or does climate belief influence political orientation? That is not a question McCright asks.

Given the politicization of climate science and political polarization on climate change beliefs in the US, it is not surprising that attribution of warmer-than-usual winter temperatures to global warming is filtered through partisan and ideological lenses.

Or maybe people’s voting habits are filtered through logical-lenses and they turned away from parties which pushed stupid ideas? How about that hypothesis?

[Science Daily]

Global warming skeptics unmoved by extreme weather

What will it take to convince skeptics of global warming that the phenomenon is real? Surely, many scientists believe, enough droughts, floods and heat waves will begin to change minds.

But a new study led by a Michigan State University scholar throws cold water on that theory.

Major industry in UK plays guessing games with electricity, warns of shutdowns in winter

Somewhere in the country that led the Industrial Revolution, hundreds of the best and brightest most-productive workers work full time at predicting, gaming, marketing and compensating for the complex modern laws of electricity. And during winter months, thousands of other productive workers have to stop work because the electricity they need might be too expensive. With the UK’s spare electrical generation capacity down to a razor thin 4% this winter, UK manufacturers are warning they will have to shut down even more often than they already do.

Someone thought it would be a good idea to use the UK electricity grid to control global weather, which turned out to be expensive. In a plan to contain electricity costs, someone else had the bright idea to trim back electricity peaks by charging a lot lot more during the worst three half hour periods of energy demand, known as triads. The mysterious triad spikes are subject to the weather and human circadian timetables and hit a bit randomly, though most often on a Monday to Thursday from 5 – 5.30pm.  By definition they occur in winter months,  and must be separated from the last triad by 10 days (though I didn’t think the weather worked like that?).

No one is exactly sure when the next dreaded triad will hit and contractor services and online calculators have sprung up to try to predict them. Even after they’ve hit, no one can be sure they had a triad, because they won’t officially find out ’til the end of February when those peakiest of peak winter days can be identified. When businesses guess that a triad might be about to happen they can shut down or crank up the spare diesel generators. By doing this a large corporation might save £50,000 of its electricity bill.

In a mild winter, when electricity demand is flatish, the expensive triad times are only little spikes and are very hard to predict. So, this genius of bureaucratic planning creates a situation where mild winters with lower electricity demand may mean more shutdowns. Go figure.

 Green Britain: UK Manufacturers Warn Of Shutdowns Amid Energy Emergency Measures

Date: 23/11/14    Tanya Powley, Financial Times

Britain’s heavy manufacturers have warned they may be forced to shut down more often this winter to avoid high power costs because of emergency measures to cut demand.

Nine poll shows 69% of Australians “don’t believe” in man-made global warming

Channel Nine asked it’s readers “Do you believe in man-made global warming?” Over 122,000 people responded.

The final tally emailed to me this morning was:    Yes: 38,311     No: 84,240

The tally at 1:50pm EST.

As far as I know, the link to it was not posted on any major skeptical blog except possibly in comments (correct me if I’m wrong). In other words, the poll may be a reasonable representation of the web audience of one of our major free-to-air TV Channels.

A few weeks ago ABC Radio national did an online poll asking their readers if the IPCC was right about a four or five degree warming this century.   That was too extreme, even for ABC readers: 91% of 3101 voters said “No”.

A new US poll finds that even though most Americans identify with what would be called environmental values, hardly anyone thought climate change mattered. The Washington Post:

…”64 percent ‘feel a deep connection with nature and the Earth.’”  

Just 5 percent of Americans thought climate change was the most important issue in the U.S. today.”

Amber comments on climatechangedespatch: “5% must be the university profs and the donation seeking green blob to get it that high.”

Believers may have the run of the old media, but Skeptics are all over the new media. And that’s no accident. (Think preaching from the pulpit versus the printing press, when the latter appeared a few hundred years ago.)

Google Engineers give up on renewables fixing the climate (but they still miss the point)

Today’s renewable energy technologies won’t save us. So what will?

Two engineers who worked on the Google  RE<C project admit with candour  that they used to think that renewable technologies could help prevent climate change, but they now know that was wrong, saying “Today’s renewable energy technologies won’t save us. So what will?” The brutal answer eventually is “we don’t know”. The RE<C project started in 2007 and was buried in 2011. Google invested $850 million in clean energy. (For a tiny $100,000 I could have saved Google $850 million dollars. If they only asked skeptics instead of Al Gore…)

Ross Koningstein & David Fork admit with admirable honesty that their assumptions about renewables were wrong. But they still haven’t realized their assumptions about climate models are wrong too. Next year perhaps?

Most of their article is about the engineering hurdles of dispatchable and distributed energy. But they also talk about the Google time management philosophy, their 70-20-10 rule (70% core work, 20% cutting edge but viable, 10% “crazy” possibilities). What they don’t seem to realize 70:20:10 is pointless if 100% of their time is spent solving a problem that doesn’t exist. The Google innovation approach is a pot-luck dip. Five percent of any project — and it’s the first 5% — should be about testing all the assumptions and right back to the very first one. If Google did this research it would have been obvious, and years ago,  that not only were renewables unlikely to reduce CO2, but that reducing CO2 was pointless, and indeed, probably counter-productive.

It’s not just about wasting time and money. What if you spend years trying to improve the weather, and not only failed to do that, but had the perverse side-effect of reductions in crop growth, and increases in food and energy prices? What if your main success was to increase the size of deserts — CO2 feeds plants and extra CO2 has the biggest effect on plants in arid zones. How would you feel if you tried to hold back the tide (which is barely rising) but children died of starvation instead?

For the record, the  assumptions they should have tested were 1/ whether climate models are better at predicting the climate than any roulette wheel. 2/ whether there is any empirical evidence that climate feedbacks (especially water vapor in the upper atmosphere) are positive and amplify the effect of CO2 (they aren’t and they don’t). The evidence has been there for years that temperatures drive carbon dioxide, and that if carbon dioxide amplifies the temperature the effect is so small it can’t be measured with modern technology and the best data we have.

Spectrum IEEE

Google’s boldest energy move was an effort known asRE<C, which aimed to develop renewable energy sources that would generate electricity more cheaply than coal-fired power plants do. The company announced that Google would help promising technologies mature by investing in start-ups and conducting its own internal R&D. Its aspirational goal: to produce a gigawatt of renewable power more cheaply than a coal-fired plant could, and to achieve this in years, not decades.

As we reflected on the project, we came to the conclusion that even if Google and others had led the way toward a wholesale adoption of renewable energy, that switch would not have resulted in significant reductions of carbon dioxide emissions. Trying to combat climate change exclusively with today’s renewable energy technologies simply won’t work; we need a fundamentally different approach. So we’re issuing a call to action.

UK voters tired of “big” or “bigger” government. UKIP wins again!

Government, Opposition, what’s the difference? It’s all become shades of “bigness”.  With the UK Big-Government orbiting in the  shadow of the Mega-Government in the EU, is it any wonder an alternative had to spring forth? And Lo…

In case you haven’t heard, Mr Reckless left the UK Tories, joined UKIP (the UK Independence Party) and just won the byelection becoming UKIP’s second member of Parliament. It surprised quite a lot of people.  Analysts are abuzz: the electorate was not as old or white as the first seat UKIP won, and it was ranked 271st on the list of seats UKIP “might win”. Labor won just 16% of the vote.

People seem to like the idea of small government, lower taxes, and politicians who don’t promise to change the weather. Who would have thought?

Perhaps the mighty English will one day even win the right to buy powerful hairdryers, and serious vacuums? We dare hope!

UKIP’s victory was in many ways even more impressive than their triumph in Clacton. The ease with which they demolished a 9,000 Tory majority was striking and this after the Conservatives had strained every sinew to halt the UKIP bandwagon.

Peter Spencer versus The Commonwealth — starts Monday in the Federal Court. Help Needed!

It’s a trial described as potentially “bigger than Mabo”

Peter Spencer’s story is one I didn’t think could happen in Australia. He is the farmer in New South Wales who bought a farm and then lost 80% of it when rules changed to stop people clearing native vegetation. Unable to use most of his property, he was slowly bankrupted. Though he broke no law, he lost his life’s work and his beloved farm in late 2010. There was no way out. He couldn’t sell the property — who would buy a piece of land that could not be used? Farmers all around Australia lost billions of dollars in assets as the value of their land and produce declined. The legality of this is finally being tested in the Federal Court in Sydney starting this Monday, November 24, and continuing for the next three weeks. Hold your breath. This could be an enormous case, with implications for land holders across the continent.

Much of his farm was native forest. This is the northern edge of Spencer’s property (Saarahnlee)

The Federal Government can’t take your assets  without paying, but the state governments can

The Native Vegetation Acts were brought in by the states to stop farmers clearing native plants — but no compensation was ever paid to farmers. The Federal Government used the carbon credits contained in that vegetation to meet Australia’s obligations under the Kyoto Protocol, yet the burden of supplying these credits fell on some farmers and not on other Australians.

The Commonwealth is not allowed to confiscate assets without due compensation — it’s in the Australian Constitution. But states can do it. So what if the Federal Government makes an arrangement with the states for the states to make the confiscatory laws instead — does that get around the Constitution, is that ok?

Carbon credits stored on farms are worth a lot of money

If Australia had emitted more than it was allowed to under the Kyoto Treaty then the Federal Government would supposedly have had to purchase carbon credits from overseas. As it happens Australia did meet its Kyoto obligations — our average emissions during 2008 through 2012 did not exceed 108% of the emissions in 1990 (the base year). In the event, after 2012, the countries that failed to meet their Kyoto obligations did not actually purchase credits, but when the Treaty was signed and when the Native Vegetation Acts were passed it was widely thought that they would have to. Some of the touted carbon credit prices were quite high– the recent Carbon Tax was $24.15 per tonne, for instance — and national emissions are measured in billions of tonnes.

Australia met its Kyoto obligations by stopping land clearing, but otherwise pretty much pursuing business-as-usual. The cost of meeting Australia’s obligations thus fell almost entirely on those farmers who were prevented from land clearing, and it was the Native Vegetation Acts of the states that did the preventing. In the 1990 base year, about 23% of Australia’s emissions were due to land clearing. By stopping land clearing, Australia could emit about 31% (= 8% + 23% ) more in the average year in 2008 to 2012 than in 1990, in all other sectors combined.

The Native Vegetation Act also has the perverse incentive of discouraging farmers from planting native plants. It now makes more sense to plant foreign species. What farmer could afford to let Australian trees grow?

Peter Spencer is doing this on behalf of all property owners in Australia and is determined not to give in

Peter Spencer

The funding ran out mid year,  so he is representing himself. Spencer applied to the judge in October for more time to raise funds and find a lawyer to represent him, but the judge decided that the case was of public importance, had been delayed far too long already and he should go ahead without a lawyer. Spencer feels he has no choice but to make the most of it.

A satellite image of Saarahnlee It is almost all mountainous native bushland. Yellow markers show significant points on his farm.  (Click to enlarge).

Peter Spencer’s fight has been going on for years. Remarkably, he soldiers on, undaunted, long after most men would have given up. Read this ABC interview from 2005 for a little background.

His farm, Saarahnlee, was possibly the highest altitude working farm in Australia, near Adaminaby at 1,500m.  Spencer was involved in research and development toward high altitude projects like Merino breeding programs with CSIRO, trout farming, Korean Ginseng, and forest harvesting of Mountain Gum and Mountain Ash. At the highest point of his property a study on wind farming with a hydro pump system was under development with the ANZ Bank. The aim was to make it profitable without government subsidies. Spencer was pursuing creative and experimental projects related high altitude farming in Australia.

Should Australia be  a country where honest work and personal assets can be randomly destroyed without compensation by the governmentShould a few citizens be forced to bear the costs of the many, or do we share the load fairly?

If we want Australia to be a free and fair land,  we need to do something: to draw the line — and stand up for what we know is right. The creeping power of capricious bureaucrats must be halted.

What kind of country do we want to live in?

He needs our help.

Fossils show models can’t predict how climate affects animals

Fossils show those dang mammals lived in all the spots they weren’t supposed to live in. Climate models don’t predict the climate, and animal distribution models don’t predict (or in this case hindcast) animal distribution either. How little we know, and how adaptable is biology?

This calls into question all the headline prophecies about the extinction of cute furry critters due to climate change.

The modelers were sure that animals would be unable to cope with temperature changes and would not have lived in the same places as they do now during a climate so different. By crikey, it was an ice age!  Yet those small mammals, whose defining biology is that regulate their own temperature, flummoxed the models by living nearer the glacier sheets where the models predicted they would not live.

All the alarming forecasts of local extinctions of mammals come from assumptions built into modern models that fail in multiple ways. The temperature changes from the last 20,000 years show that these mammals have already survived massive shifts, both colder and warmer, and that anything we face in the next century is but a flea on a hippo.

In the graph, the dots are the fossils, the blue marks the hypothesis — the zone where they were supposed to be confined. The stripes mark the ominous ice-cap-from-hell. (Where will those Canadians go?)

Figure 1. Paleodistribution maps for the five mammal species under consideration. Points highlight fossil occurrences, blue-shaded areas indicate ENM hindcasts, hashed area indicates extent of glacial ice. Red points are from the high confidence window (both maximum and minimum ages within 40–17 ka) and yellow points are added in the inclusive window (only maximum age estimate within 40–17 ka).

Study namecalling at Queensland University

Would you too like to learn how to misinform people, mangle English, and toss cherry-picked factoids that avoid the real point? How about studying to be an apologist for scientists who take your taxes, but hide their data? Or perhaps you’ve always dreamed of being an obedient useful fool for the State, to help promote propaganda that governments can change the weather if the people just pay enough money?

Are you looking for a cause to pick up that you can brag about at parties to prove your social superiority, impress teenage girls, or hide your low self-esteem? Do you crave an outlet where you get the thrill of being a namecalling bully, but with the excuse that you are “saving the planet” and “being scientific”?

Good news, Queensland University is dumping any pretense that its science faculty uses logic or reason or has an interest in observable evidence. The university is advertising that abusing English definitions and words meets its standards of higher education. After all, no one denies we have climate, and “climate deniers” don’t exist, but it’s a useful propaganda term to fog, veil and clog up the public debate about climate science. John Cook who runs the course even admits that it’s an inaccurate term, but he won’t stop namecalling. The last thing we want of course, is a polite discussion of a complex topic. If fans of the man-made climate crisis have to provide evidence, or answer questions, the facade would crumble.

The best defense is offense, and the best offense is to be really offensive. Bring on the namecalling, derision, and character assassination. Skeptics are scum like holocaust deniers, and have a brain like a lizard. Don’t listen to them whatever you do!

Come learn these stone-age techniques: serve the names up with half-truths, lies by omission, and be a better useful idiot. Big bankers, parasitic industries, and self-serving politicians need you!

About this Course

In public discussions, climate change is a highly controversial topic. However, in the scientific community, there is little controversy with 97% of climate scientists concluding humans are causing global warming.

In the climate science community there is little controversy, because most people who question the hypothesis have been sacked, attacked, find it hard to publish papers and are subject to name-calling, exile, intimidation, and “climate apostasy“. There are no grants for skeptics, and monopolistic funding has purchased a “consensus”.

John Cook’s unscientific 97% study started as a logical fallacy, and ended by using irrelevant and mis-assigned papers to claim that a 0.3% consensus by their own definition was actually a 97% consensus (by quietly using a different definition). Nonetheless it is a quasi proxy for funding ratios in climate science, though it overestimates skeptical funding because many skeptical papers are written by volunteers. The real funding ratio is not 97 to 3 but more like 3500 to 1.

  1. The study can’t be replicated. (Legates et al)
  2. The data is hidden. Either Cook et al didn’t keep it (and are incompetent) or they did but it does not reflect well on them and they won’t release it (they are incompetent and deceptive too?).
  3. The definitions changed between the claims in the abstract and those in the paper. (Legates et a;)
  4. The raters were not independent. 7% of the ratings were wrong, and biased.
  5. The ratings data shows inexplicable patterns.
  6. Cook et al fail to report that their data fail their own validation test. 
  7. Most of the papers were irrelevant. Those authors were writing about “impacts” or “mitigation” of climate change and not about the cause of climate change. Obviously skeptical scientists will not write about “mitigation” or “impacts” of climate change, so including these papers (and there are thousands) served the purpose of increasing the total number of papers claimed to be surveyed and also increases the percentage of “consensus”. That is an utterly predictable outcome. Good PR, lousy design.
  8. It’s not a representative sample, and Cook did not test to see if it was.
  9. The paper is used to make profoundly unscientific statements in the media. Cook et al endorse the fallacies.

In the wider scientific community there is so much controversy that skeptics outnumber believers, scientific associations have had revolts about climate change, scientists have quit their failing institutions, protested by hundreds on blogs.

Germany gives up on emissions target. Japan emits more CO2 than ever

So much for momentum on climate change. Reality bites. Without nuclear power, Japans emissions have hit a new record high. At the same time, even with 17% of its energy from Nuclear power, and with 23,000 wind turbines, Germany stands no chance of reaching its emissions targets. The rich, technologically advanced nation that has spent more than any other on green energy admits they’ve failed.

Those who want to stop producing CO2 have billions of dollars to spend on advertising and pointless windmills, but in the end, chemistry and physics can’t be bought. If renewables could provide cheap reliable power, they wouldn’t need subsidies. Everyone would buy them.

Germany to Abandon “Strict” 2020 Target – 40% cut not possible

Breitbart London

Germany’s Vice Chancellor, Sigmar Gabriel, has indicated that the country will abandon its commitment to reducing CO2 emissions by 40 percent by 2020, from a 1990 base level. In doing so he has won the ongoing clash with his own environmental minister Barbara Hendricks over energy policy, telling her that he will tolerate no further resistance to the change of direction, according to Der Speigel.
