  • Stealing Commodities – Our infrastructure is (unwittingly) built around the assumption that the materials it is composed of are, and will remain, cheap, and not worth the trouble of stealing. If this assumption breaks down, copper power lines start disappearing from the desert, and iron manhole covers begin to vanish in the night. Problematically, the raw materials (even when valuable) are still only a small fraction of the value of the infrastructure, meaning replacement costs are high. If commodities were to remain "expensive" in the long run (i.e. worth stealing), how would we re-design our infrastructure systems?

  • Dyson as Sociologist? Death Trains, Values, & Climate Action – Not sure I know quite what to make of Nisbet's take on Dyson. I agree that the catastrophe narrative is dangerous, and much prefer Richard Alley's precautionary point of view, but I really think Dyson is catastrophically wrong on this, and potentially dangerous as a figurehead, whether knowing or unknowing.

  • Argentine economics and maker culture – An interesting and personal look at mass production vs. local/handmade goods based on currency strength and protectionist trade barriers. Where labor is cheap, the food and goods are often unique. Where it's expensive, you get mass production. Makes me want to bike S. America. Again. (tagged: economics argentina local money food )
  • China Out to Dominate in Electric Cars (and Why Not GM) – A short chronicle of GM's missteps toward electric vehicles, and China's long view of the same. Honestly, I don't care much who does the dominating, so long as somebody gets this market going. (tagged: cars transportation technology economics china )
  • Oregon’s mileage tax experiment – If you can imagine an America in which vehicle fuel economy increases with time (despite the fact that our national fleet today gets the same mileage as a Ford Model T), then eventually, funding road maintenance with a gas tax becomes a problem. Instead of taxing the fuel, you need to directly tax the road usage – miles driven, normalized by some kind of wear-and-tear factor for a given vehicle. Thus, the idea of a VMT (vehicle miles traveled) tax. Political suicide, you say, but it worked in this (politically insulated) trial in Oregon, and is going ahead gangbusters in the Netherlands and other nations, coupled with GPS enabled congestion charging, and time/location dependent parking fees, it could go a long way toward making personal transportation costs transparent and efficiently priced.

Have you seen the light?

As animals, and especially visual animals at that, we have a particular experience of the light.  For us it is illumination, information about our surroundings.  For that purpose moonlight or even starlight will do.  And for tens of millions of years, that’s all we ever saw.  Somehow a few of us made it through the Permian extinction, and into the Triassic, but the ascendancy of the dinosaurs eventually forced us into the darkness of the night.  Our world became dim, and our eyes went colorblind.  Most mammals today see only two colors, but a few of us have re-evolved a third photoreceptor.  Three colors is still inferior to the four or five or six seen by many near-surface fish, birds, reptiles, insects, and other arthropods.  The stomatopods are almost biological spectroscopic imaging systems, with 12 color channels in each of their independently movable trinocular eyes.  We are lesser than the eyes that never left the light.  They stole the colors from us and made us hide within the night.  They kept the sun for themselves, not knowing that our small and furtive ways, our burning endothermy and our fur would see us through the aftermath of the KT impact.

How important is local food?

From a purely climatic point of view.

Assuming the following:

  1. For each calorie of food you consume, the equivalent of 9 additional calories worth of gas were burned to get the food to your plate (this is industrial food production).
  2. You eat 2000 calories per day.
  3. Your car gets 30 miles per gallon.
  4. Each gallon of gas contains the equivalent of 30,000 calories worth of energy. Continue reading How important is local food?
