It’s always a great time-saver to rewrite someone else’s copy (read press release or news feed?) and it can be a space saver too if you leave enough out. Check this one out:
Stiffer roads would save fuel
Study finds that road surfaces contribute to increased fuel use.

Scientists have found that some road surfaces require more energy to drive along, increasing fuel use.

Wow, a softer road will absorb more energy, who would have thought? So make it stiffer and your car will go further. (Excellent. So why not just replace roads with rails, then, and save a lot more?)

Aside from the obvious, this is a statistical modeling study (and fair enough), not an empirical one. And it’s based on US data. But the conclusion is intuitive anyway. Make the road stiffer (thicker asphalt or replaced with concrete or a blend) and you’ll save on fuel consumption. But what the SMH doesn’t mention in Barry Park‘s version of the story is that the research was conducted as part of the Concrete Sustainability Hub at MIT, which is sponsored by the Portland Cement Association and the Ready Mixed Concrete Research & Education Foundation. Now it’s admirable that the concrete industry wants to make concrete “greener” but it’s also worthwhile noting that they want to remain in the concrete industry, too.

So rather than remake roads with stiffer but carbon-dirty materials like concrete, why not open up the thinking and look outside of the box a bit?  Slow cars down: wouldn’t that also save money? Reduce the weight of cars? Or switch more car trips over to public transport. Or – even better – price fuel higher and discourage over-use – there’s an alternative! If we tore up roads or simply poured more concrete in scheduled replacement we may indeed save a relatively small net amount of fuel but maybe there are cheaper, better ways of achieving that? And in any case when it really matters, say where traffic is at its fastest on a freeway, aren’t they ‘stiffer’ concrete or concrete/asphalt layers already?  

There’s a better account of the story, here:
Civil engineers find savings where the rubber meets the road | News | ECN Magazine

The researchers say the initial cost outlay for better pavements would quickly pay for itself not just in fuel efficiency and decreased CO2 emissions, but also in reduced maintenance costs.

“There’s a misconception that if you want to go green you have to spend more money, but that’s not necessarily true,” Akbarian says. “Better pavement design over a lifetime would save much more money in fuel costs than the initial cost of improvements. And the state departments of transportation would save money while reducing their environmental footprint over time, because the roads won’t deteriorate as quickly.”

This research was conducted as part of the Concrete Sustainability Hub at MIT, which is sponsored by the Portland Cement Association and the Ready Mixed Concrete Research & Education Foundation with the goal of improving the environmental footprint of that industry.

“This work is not about asphalt versus concrete,” Ulm says. “The ultimate goal is to make our nation’s infrastructure more sustainable. Our model will help make this possible by giving pavement engineers a tool for including sustainability as a design parameter, just like safety, cost and ride quality.”

Well, more time, anyway.

 1. That modern democracy is the best way to govern.
Yes, it works, more or less; but is it the best design for effective decision-making? On the plus side it gives voters a sense of engagement with “government” and, if enough people are involved in the process, quells unrest to a large degree. But increasingly it appears to favour popularity and polling over substance and intellect. In some ways modern democracy works by seeking out the lowest common denominator rather than the best set of solutions. And if the popular vote rests in the wrong hands at the wrong time it can lead to poor decision making that is hard to unravel. And this seeming dive to the depths is exacerbated by the ease with which our connected society can now communicate, allowing an easily embraced and marketed notion, irrespective of substance or even veracity, to be repeated endlessly until it becomes “substantial” and majority-believed. Whereas less marketable, more complicated ideas fail to get across to the masses. (Look at the anthropogenic climate change debate!) Thus you end up with more support for the weaker, less effective notion rather than the stronger, more complete or complex one.

 2. That Generations theory works.
Whilst demographics include the study of real and measurable cohorts of people, for example swelling birth numbers in a generation or two being labelled a “baby boom”; how substantial are the other labels we throw around with such ease? We have ‘Generation X’ largely because it is the demographic that comes on the tail end of the post-war ‘baby boom’, which is fair enough as a door-stop if you like. And after that a slew of labels that are tied not to changing birth numbers, wars, or clear, widely accepted changes in behaviour but, rather, sheer marketing convenience. Does it really matter what consumer goods were on the market when you were born, or whether you get driven to soccer practice by your mum every week? Does that overcome good schooling and parenting or even our inherited genetic material? The names are as fanciful as their statistical validity, which is often as profound as astrology, or perhaps even less so. Gen Y, Gen Why? Gen Next? And the point of these labels is to… simply label people, for marketing convenience. Haven’t we gotten over that yet?

 3. That Religion and spirituality is an alternative to science.
 Although people like to blur the lines sometimes, in truth science is open-ended and transparently mutable – that is to say that it’s open to question and can readily change. Whereas spirituality and associated beliefs survive uncontestably outside of logic and reason and are based on accepted “truths”. Which is not to say that religion and sprituality in general are “bad”, of course, nor that science is “good”. There is a place for each in our lives. They are just different things. New scientific “facts” arise from contestable theory and are open to intelligent, educated critique. Which is surely good. And, yes, religious beliefs can change, too, but the key thing about faith – or belief – is that you accept them. They are not presented as a “theory”. To question or deny them goes against the grain, at least for most people, most of the time. So why do so many religions see the need to fight or argue against science? Is it because they feel threatened by truths that conflict with their own unsupportable ideas? In which case the logical approach would be to accept the current science as the best truth we have and review instead the conflicted areas of your own beliefs, rather than rail against the science alone. Which, admittedly, sometimes – though too rarely – is the case.

 4. Progress is speed, speed is progress.
We must always be moving forward – and to so we need faster cars, faster trains and faster planes. In essence, to slow down is to fight against progress. Why is it so? Why is speed the major determinant of ‘progress’ in so many minds? Surely less waste, more efficiency and a better overall environment matters more than velocity alone? It’s a narrowly focused mind that solely wants to speed things up, a mind that overlooks the whole picture. Discuss.

  5. The Good Old Days, or today’s ‘nanny state’.
It was always better ‘back then’, and in some specific cases maybe it was. Usually it was riskier, less restricted, more “free” and unobserved, at least in some people’s minds. Often this is tied to criticism of the “nanny state”, an idea that has some validity, perhaps, but has become both a cliche and a lazy label. In truth the past is riddled with avoidable injury, unfairness, distress, pain and disease. What we have now may be more cosseting and less risky but it’s a calculated trade off as well, a deal where we get a better, safer life and lose some of our riskier behaviours. We have certainly tended towards overprotection and over-evaluated some risks, especially with regard to our children, but we have also measurably reduced needless injury and death. If the trade-off needs adjustment, do so. But don’t just label everything you disagree with as part of the ‘nanny state’. Take personal responsibility instead and live your life on the edge, or as close as you wish. See what happens. And don’t neglect your medical insurance!

6. Consumerism and materialism.
Need I explain? Consumerism is great at driving economic benefit but it also drives waste and inefficiency. You’d imagine the opposite would be true, that it would drive efficiency and effectiveness too, except that we fail to account for what economists call “externalities”: those things that are affected by or are generated as a result of our activity. Like waste, pollution, loss of habitat and species diversity. And so on. We not only hide these things and fail to price them into our products and activities, we distort the market by actually subsidising wasteful practices. Every government does it. Especially democracies, where the popular vote, money and marketing speaks loudest.

7. Vested interests and entrenched power.
Oh yes, the popular vote, money and marketing at work – again. This is really coming back to “modern democracy”, where the loudest, most cashed-up voices often prevail. You’d hope that democracy would’ve toppled the old dictators, but no, they have simply adapted. Simple ideas gain support over the more complex, harder to explain ones. Like anthropogenic climate change is buried under the shouting of coal miners and other vested interests. And cashed-up voices with a personal stake in the argument can use their resources to shout down the common good. Like running TV ads against a resources tax. Not everyome can do that, only the rich, and usually those with, yes, vested interests. You know who you are.

8. Self-interest vs the community interest.
Ditto. It’s a battle that has been going on forever. You own a waterfront property that is affected by climate change, of course it’s going to affect your personal wealth at some point. It’s a trade off, like living on the edge of a cliff. ‘Great view, pity about the erosion.’ Your local council has a duty to the greater community to prepare for inundation and erosion and take action to alert the public by appropriate land zoning or other regulation. So do you fight against your probable loss of property value or accept that it’s unfair to sustain your wealth at the expense of a future buyer who will have to bear the future loss? That’s just one example, of course, but it illustrates the concept.

9. Persuasion, opinion and fact.
If there’s one thing I’m confident of, it’s that I’ve made mistakes. More likely than not I’ve made mistakes of fact, logic or judgement today, right here on this virtual page. I can only do what I can do and be authentic to myself in doing so. It’s what I am thinking right now, translated into words; nothing more, nothing less. I’m equally certain that everyone makes mistakes, sometimes serious ones, more likely or more commonly less so. Now if I were a confident or persuasive person I’d probably tout my views publicly and push them out to other people. And in some ways I am and I’m doing exactly that, right here. But in other ways I’m not promoting or marketing these ideas much at all. I’m just making them available. The alternative is to do speaking tours, get on the radio or TV, write and promote a book or join an organisation that pushes a set of ideas, like religious zealots or professional politicians may do. It’s important to reflect upon their intentions, to ask whether they are being authentic to their own beliefs, and to recognise that they may be using tricks of the trade – or their wealth or power – to amplify their opinion over others. And to remember that everyone makes mistakes.

10. List-making and list-makers.
Don’t you hate ‘em?

I read an article about the tricks and traps of our digital age, which drifted around from planned obsolescence to tricky marketing. A comment spurred me to deconstruct the idea that planned obsolesence is “good” because it “creates jobs”:

Planned obsolescence has a few flaws. With material goods it creates physical waste, up to now a hidden cost that we *all* have paid (usually by government subsidy). As externalities like waste are factored in (by for example pricing carbon emissions) the real cost of obsolescence is revealed and it doesn’t look so good. Secondly, whilst obsolescence is thought to be a great idea to ensure that someone comes back for ‘another one’, it only works in monopoly markets or close thereto, or where loyalty or some other sticking force (like a low cost shaver and high-cost replacement blades) glues the buyer to the brand. If the market is truly “free” they only come back if they are satisfied with the first one. As soon as a competitor makes a longer-lasting, better or more serviceable product the short-lived-by-design product will fall from favour. Basically planned obsolescence relies on imperfect markets, government subsidy, marketing tricks, and/or inefficiency to actually work. If that’s what you want, fine, but what about the free market, efficiency and innovation? What if we deny ourselves the better product and pay through the nose for the privilege of getting the lesser device? Is that actually generating jobs for us, or setting us up for a later catastrophic economic failure?

Oops, it may have just happened!
