My kid loves statistics and 15 minute cities

My kid’s transport goals for the year

We have started this simple diary where my 7 yo tracks each of her trips and categorizes them as car or not car. I find the analog simplicity of this approach to be appealing and I’ll be helping her keep this updated. I am also resisting temptation to add more data to this survey for myself (her project, not mine!) My movement goals are the same as hers, walk and bike as much as practicable leaving driving only for the “it’s too far or I don’t have even 10 minutes to spare or I have to carry something that won’t fit on my cargo bike, or it’s not safe to bike with a kid”.

Our life for the most part now fits the 15 minute city model, the concept that “Everyone living in a city should have access to essential urban services within a 15 minute walk or bike.”. Other than my once a week commute to work, almost everything we do is in that 15 minute walk/bike window and while our all age and abilities bike network is still work in progress, the trend is clear (thanks Dave Thompson Victoria City Councilor for the graphic from the CRD transportation survey)

  • Hitler's fuel to get giant subsidy. What about solar?

    Apparently, my political prognostication skills are good. Coal state shills senators want to give coal to liquid fuel a $10 billion dollar subsidy loan.

    Democrats Propose Loan Plan for Coal Plants – New York Times

    As the Senate began debate today on a sprawling bill to reduce oil consumption, top Democrats were circulating a proposal to provide $10 billion in loans for plants that make diesel fuel from coal.

    The proposal highlights the horse-trading involving powerful industry groups as Democratic leaders push for legislation that would require higher mileage in cars and a huge increase in the production of renewable fuels made from plants like switchgrass.

    Yes, one of the lesser known provisions of these bills would expand renewable energy subsidies to coal.

    As mentioned before, U.S lawmakers are losing their collective mind in exchange for lots of money. This is corruption too, you know, at a level that is unfathomable to your average two-bit third world dictator!

    Meanwhile, how much money is spent on solar related research? You know, that big ball of wholesome renewable energy. This post on the reality based community blog explains why silicon production for photovoltaic cells is stuck.

    The problem for the PV customers for silicon is that they are a fast grower sandwiched between two mature sectors growing roughly in line with the economy. Bulk silicon is used in old-economy alloys and sealants; and while demand for semiconductors grows rapidly in value, their extra capability is crammed onto roughly the same physical volume of raw material. Unfortunately there is no appropriate process for making PV-grade feedstock. Metallurgical-grade silicon, smelted by simple Victorian technology, largely in China, is cheap but too impure to work in solar cells. So you have to use semiconductor grade, which is absurdly over-specified for the purpose and priced to match.

    For a long time the PV companies could go to refiners’ back doors like hobos and buy at a discount the seconds, the ingots rated substandard for the real semiconductor customers, but now the demand has shot up so PV has to pay full whack. This is by far the biggest constraint on the future of PV. Making the panels is straightforward : the industry cry – just Google it – is “silicon feedstock”.

    People are of course working on finding a specific route to medium-grade silicon at $20 or so a kilo. Whoever gets there first will make a fortune and save the planet like Superman, so it’s an attractive opportunity. The problem was entirely predictable given the relative growth rates. So why didn’t it attract much effort until recently?

    I think there has been an institutional market failure. The challenge is out of the technological reach of the bulk silicon people; and the semiconductor refiners have I think been fixated on keeping Intel and company happy, customers who must be insensitive to price and fanatically demanding on quality. A $100 processor might be built on a gram or less of silicon wafer, or 5 cents’ worth – hardly worth worrying about compared to cutting rejection rates for the circuits.

    You would think that this geopolitically strategic problem would attract oodles of public research – a money cake like Alice’s with EAT ME “beautifully marked in currants”. Not so.

    The EU put €42m into PV research in the €17.5 bn 6th Framework Programme (2002-2006), with one €2.6m programme on silicon feedstock (search for FOXY): the 7th Framework programme hasn’t been approved quite yet, but funding for renewable energy will go up.

    The USA, heart of the world semiconductor industry, spends even less. The current DoE programme for PV technology offers $12.5 million over 2-3 years . Searching the DoE site with the keywords “silicon feedstock”, I found precisely one grant awarded – for a princely $99,928.

    This is the order of money the US government hands out as charity to cranks. The Pentagon used to support serious gravitational physics with the blue-sky hope of finding antigravity, and apparently funded some antigravity devices – well into the crackpot zone. NASA spent $1.6M between 1996 and 2002 on a similarly starry-eyed “Breakthrough Propulsion Physics” programme, in hopes of a real warp drive. (more)

    It’s market failure, and government policy’s job to predict and correct market failures by judicious injections of money and regulation. A fraction of this Hitler subsidy focused towards reducing the cost of high grade silicon production would, as the author of the above post put it, “save the world like Superman”

    Meanwhile, Barack (no longer senator of coal) Obama no longer supports Coal-to-Liquid technology. That removes the one black mark (can I say that?) against his advocacy positions. Here’s hoping it is a real back tracking, and not just a reaction to pressure that will be reversed once eyes are turned.

  • C + O2 = CO2

    Overall, the study estimates that fires in the contiguous United States and Alaska release about 290 million metric tons of carbon dioxide a year, which is the equivalent of 4 to 6 percent of the nation’s carbon dioxide emissions from fossil fuel burning. But fires contribute a higher proportion of the potent greenhouse gas in several western and southeastern states, especially Alaska, Idaho, Oregon, Montana, Washington, Arkansas, Mississippi, and Arizona. Particularly large fires can release enormous pulses of carbon dioxide rapidly into the atmosphere.”A striking implication of very large wildfires is that a severe fire season lasting only one or two months can release as much carbon as the annual emissions from the entire transportation or energy sector of an individual state,” the authors write.

    US Fires Release Large Amounts Of Carbon Dioxide

    In a study that is sure to be seized upon by global warming refuseniks everywhere, it has been discovered that fires release CO2. Um, however you do it, if you burn 12 grams of carbon completely, you will get 44 grams of CO2 (as you probably learned in middle school chemistry).

    I am glad this study was done, but it’s not news, and it is not a STRIKING IMPLICATION by any means. If you know the acreage of forest fires, and you have some estimation of biomass density, it’s trivial to come up with an estimate of CO2 emissions.

    What forest fires also do is put a lot of fine particulates into the air, now that is truly hazardous for people in the vicinity and has much more STRIKING IMPLICATIONS on air quality.

  • Justices rule against Duke on pollution controls

    Duke Energy, that is, not the Blue Devils!

    The Supreme Court sure has a green tinge today!

    newsobserver.com | Justices rule against Duke on pollution controls

    The Supreme Court gave a boost today to a federal clean air initiative aimed at forcing utilities to install pollution control equipment on aging coal-fired power plants.
    In a unanimous decision, the justices ruled against Duke Energy Corp. in a lawsuit brought by the Clinton administration, part of a massive enforcement effort targeting more than a dozen utilities.

    Most companies settled with the government, but several Clinton-era cases involving more than two dozen power plants in the South and the Midwest are still pending. The remaining suits demand fines for past pollution that if levied in full would run into billions of dollars.

    The justices ruled that the 4th U.S. Circuit Court of Appeals in Richmond, Va., overstepped its authority by implicitly invalidating Environmental Protection Agency regulations in a way that favored Duke. The case now returns to the lower courts.

    The appeals court’s decision “seems to us too far a stretch,” Justice David Souter wrote.

    The enforcement program is aimed at reducing power plant emissions of nitrogen oxide and sulfur dioxide that contribute to smog and acid rain. Sulfur dioxide is the leading cause of acid rain.

    The utility industry has long resisted installing costly pollution controls under the program called New Source Review. It waged vigorous campaigns against the program starting in the 1980s and more recently by battling it out with regulators when sued in federal courts.

    Federal Study Finds Accord on Warming – New York Times

    A scientific study commissioned by the Bush administration concluded yesterday that the lower atmosphere was indeed growing warmer and that there was “clear evidence of human influences on the climate system.”

    Wait, we still need to study this more, we need to eliminate all uncertainty before we act, we need more proof, we need to be more certain :-;

  • Asia's brown clouds warm planet

    BBC NEWS | Science/Nature | Asias brown clouds warm planet

    Clouds of pollution over the Indian Ocean appear to cause as much warming as greenhouse gases released by human activity, a study has suggested. US researchers used unmanned aircraft to measure the effects of the “brown clouds” on the surrounding area. Writing in Nature, they said the tiny particles increased the solar heating of the lower atmosphere by about 50%.

    The warming could be enough to explain the retreat of glaciers in the Himalayas, the scientists proposed. The clouds contain a mixture of light absorbing aerosols and light scattering aerosols, which cause the atmosphere to warm and the surface of the Earth to cool.

    Wow, I’ll have to read the paper later today to confirm, but when I was doing aerosol work in India back in the mid ’90s, the Indian Ocean cloud was unknown. 1995 through 1998, there was an experiment called INDOEX (my thesis advisor in Bombay participated in the later phases) which first observed this brown cloud. At that time, it was assumed that the light scattering (hence “cooling”) effects of this aerosol would dominate the absorbing (or “heating”) effects, and initial model estimates seemed to agree.

    Turns out that it has a significant warming effect because the soot particles (dark, therefore heat absorbing) predominate. And, you had to measure it.

    For their study, the team of researchers used three unmanned aircraft, fitted with miniaturised instruments that were able to measure aerosol concentrations, soot amounts and the flow of energy from the Sun.

    The crafts flew over the polluted region of the Indian Ocean at varying heights between 500m (1,640ft) and 3,000m (9,840ft).

    “During 18 flight missions, the three unmanned aerial vehicles were flown with a separation of tens of metres or less and less than 10 seconds (apart), which made it possible to measure the atmospheric solar heating rates directly,” they wrote.

    If true, we can reduce the size of this “cloud” by reducing biomass combustion, installing particle controls on power plants, cleaning up other combustion sources, etc, and reduce global warming effects without worrying that this cloud was somehow mitigating temperature rise as previously thought. So, a win-win!

  • The emperor's "new" climate policy

    You mut have heard by now that the emperor of the US (I call him that because he thinks he is above the law and rules by fiat) announced a new meeting to tackle climate change issues. David Roberts of Grist broke it down and concluded that it was worse than nothing. It rejects targets, groups China and India with the developed world, which ensures that nothing will ever come out of his “meeting”, kicks everything down the road until after he has abdicated his throne in 2009, and tries to take advantage of climate change to push for free trade deals.

    But this article by Dana Milbank of the Washington Post caught my attention for the rather surreal exchange between a CBS reporter and the White House spokesman.

    Dana Milbank – As the World Warms, the White House Aspires – washingtonpost.com

    In this instance, you have a long-term, aspirational goal,” Connaughton answered.

    Aspirational goal? Like having the body you want without diet or exercise? Or getting rich without working?

    “I’m confused,” Axelrod said. “Does that mean there will be targets for greenhouse gas emission reductions, and that everybody will be making binding commitments?”

    “The commitment at the international level will be to a long-term, aspirational goal,” the Bush aide repeated.

    Axelrod had his answer. “Voluntary,” he concluded.

    “Well,” said Connaughton, “I want to be careful about the word ‘voluntary.’ “

    Yes, please do be careful, let’s not over promise and under deliver like we always do!

    Connaughton may want to be careful, but the plan the White House outlined yesterday listed no concrete targets or dates, no enforcement mechanism and no penalties for noncompliance. It also wouldn’t take effect until four years after Bush leaves office. It was, rather, a call to spend the final 18 months of the Bush presidency forming an aspirational goal.

    Umm, we’re not in 1985 any more, aspirational goals have long since been established, stabilization at 450 ppm C anyone?

    I love the emperor and his merry band of climate advisers!
