Tribal Economy

Just listened to NPR's Planet Money on "the Past and Future of American Manufacturing."  It was quite a distressing podcast lamenting the loss of manufacturing jobs, wondering how good but unskilled laborers would fare in the future where manufacturing is about finesse and programming, not stamina.  The host, right after being told he would never be hired to program NC milling machines, wondered how the show's protagonist, a hard working aggressive young mom named Matty, could ever get uptrained.  The fearful conclusion was she wouldn't.

It's ironic how Adam Davidson worried about Matty's future, right after being told he himself also had no chance at that job either. I don't think getting everybody "trained up" to operate an NC mill is either needed or practical. We really do need only 1/100 as many combine drivers as scythe swingers. What an astounding efficiency gain! As they poignantly illustrated, there's tragedy here, because the machines have CREATED value, so overall life for everyone should be easier,, not tougher. Nor do I believe is it as simple as, "well there're are more of us now so the times are just as tough as ever."  Here's an illustrative fable.

--------

Thor paused, sweating.  His log was the biggest and he was in front, but he didn't need to rest.  The stop was because Ting the chief had just showed up on the crest of the next rise leading 4 of those strange new animals, "horses."  What would happen now?

The tribe was half way through their annual migration. Each year, the women built travois' and hauled the family's tent and few goods some 200 miles from the rich timberlands up north down to the arid grasslands.  The men hauled timber.  These logs were prized material to make bows & tentstakes among the hunter gatherer tribes of the south, and they'd trade food and furs that made the trip a productive annual event for the Ting tribe.  Some rich chiefs even had astounding "tents" made entirely of tree slabs stacked close, to keep out every whisper of icy wind.  They were luxuriously comfortable: the demand for the tribe's product seemed limitless.

Now old Ting had horses. He was even riding one.

"Thor," he said, looking down at his strongest haulsman while the others came up , variously puffing or wheezing according to their exertions and the ambition of their load, "things are gonna change around here."

"How, lord Ting?"

"We've got horses now.  We don't need all you men pulling.  A horse can haul as much as 3 men, and feeds itself along the way, so your job ends right here, on this hilltop.  From now on, your wife will ride, you can pull her travois with the tent on it."

"I can go twice as fast pulling that little thing.  Who'll keep up with me?"

"Well," Ting said, "the horses will be heavily loaded, so we won't go faster, but instead we'll just have more logs to sell.  If you get too far ahead each day, maybe you can do a little fishing, or nap.  Whatever."

~ ~ So, that's how it COULD have gone.  But as you know, on that day Ting instead left most of his tribe to fend for themselves. He had a horse and that made him rich and put the rest of the tribe out of business.  That pretty much set the pattern for the rest of history.

Why doesn't the largess of our technological advance translate into a more idyllic lifestyle for everyone?  

It's easy to do the "energy balance" and see that tools, animals, machines and oil have each multiplied our ability to get things done. These should have the effect increasing the potential leisure and comfort, supporting a greater population, or some combination of those. That we always choose option #2 seems like a problem in our programming.

Even if we preferred leisure over consumption, there is still a problem of distribution.Everyone needs to benefit from the technological improvement, but ownership tends to concentrate, as the return on investment allows Ting (and nobody else) to buy another horse. Would stock ownership allow the little guy to buy a small piece of the technology? Why hasn't that worked.?

If ancient Norse beer technology advancements doubled yield, why couldn't everyone just have two?  It seems a simple calculation, but maybe it's the problem as well. First of all, everybody has to increase their consumption to keep full employment or, in the case of items with intrinsically limited demand (ok so not beer, but there must be something...) the technological advancement, whether the horse or the automated brewery, brings a reduction in employment as a nominal consequence.

 The benefit is the commodity price drops thanks to lower labor, but what's the laborer supposed to do?  You obviously can't put the reduced price genie back in the bottle, nor is dragging logs by hand any longer a viable livlihood. You can't compete with a horse just as John Henry couldn't compete with a steam hammer. Is a requirement for growth the consequence of advancement?  Cold bloodedly, in the absence of consumption growth, starvation will eventually balance the labor market to the need. More hopefully though, assuming constant GDP (same number of logs dragged) a pair of hands has been idled, that's potential to create more wealth for us all to share. That's if we can gracefully repurpose and retask the displaced individuals, but why not?  Humans are flexible creatures. Maybe now Thor will carve totem poles the plainsmen can afford to buy since logs are cheaper. This is growth.Is there a problem?  Well, maybe. Another stable balance would involve MORE plainsmen consuming all the logs that could be supplied even with horses. Everybody's still pulling for all they're worth.  Subsistence, only more of it. This scenario need only arise if we wastefully expend every technological windfall in the name of more human mass until (see Collapse of Complex Societies) we are dependent on all the latest gizmos just to get by. Problematically, it seems the natural outcome.

Good day brewing yesterday. Hoping for a pilsner. It came out very strong: O.G. 1.059!

Flavor

Palmer suggests a 2-dimensional flavor spectrum of fruity/malty  bitter/sweet to characterize beer styles.  Eg pilsner is malty-bitter, while IPA is fruity bitter  Weisen is fruity-sweet and dark beers are malty-sweet.  Kolsch, he put right in the center.  Lots of this is from his gospel, too.

Hops: Certainly I associate hoppy with bitter, but cold hopping (eg after the fermentation break) is a favorite of mine because it gives fruity smell without as much bitterness.  This means in flavor space, the hop vector is a diagonal from [malty sweet] downward towards [fruity bitter] with some variation in proportion based on when you add the hops.  Boil the hops to extract bitterness but lose the aroma, & conversely. 

Tannins: astringent. come from hops, grain husks, wood.  High pH and high temp, canonically > 170 encourage them. They can precipitate out (hence the benefit of lagering).  In brewing pilseners and lagers, low buffering capability of the malt makes tannins a risk. Distilled water is recommended (but we have pretty good water here on the front range.)

Sweet: comes from high temperature mashing, when alpha enzymes randomly chop carbohydrates into indigestible lengths (& beta is deactivated), or especially from caramelized malts.  So for example, to avoid sweetness in pilseners, mash cool and don't use any caramel malts.

Fuseols: taste like "hot" alcohols or solvents.  I once had a beer that tasted like turpentine.  Further conditioning cleaned it up though, as the yeast digested the alcohols.  Caused by exuberant early fermentation, eg overly warm temperatures.

Body: comes from proteins.  Oatmeal (with a protein rest) or from most grains, keep the protein rest short so you don't break down what's left in the grain.

Fruity: comes from esters, from yeast. Ale yeast & warmer fermentation tends to fruity, lager yeast and cold fermentation leans  more to "clean"

Vinegar: Bacteria.


Energy to Burn

A coal train just went by. I've been wondering about some power factoids, so finally looked them up.

  • Boulder  consumed 1,160 million kWhr (in Y2k)
  • 91% from coal power.  I don't know if it's mostly all generated in that one plant or not. 
  • Coal -> steam turbines -> electric generation runs about 35% efficiency.
  • 42 million kWhr from hydro, by the way.
  • we pay $114 million/yr (that's 10c/kWhr? Sounds high...)
  • 100 tons of coal in a RR car, and 1 lb coal/kwHr (nice neat numbers, eh?)
Therefore, Boulder burns 1 RR Car of coal every 90 minutes.
