What did Native Americans make of the French in the 16th century?

Preface. My first exposure to philosophy was in High School, about the philosophies that helped shape the U.S. constitution. This led me to read Rousseau, Hobbes, Locke, Montesquieu, and others. “Dawn of Everything” points out that Native American philosophies should have been given credit, since this is likely where some philosophers got their ideas from via bestselling books written by French monks and others who lived with natives while trying to sell them Jesus.

Dawn of Everything Conclusion

Preface. Clearly for their conclusion to make sense you’ll need to read the book and see the evidence for yourself.  Since they challenge just about all of the ideas currently in fashion, you can find some pretty damning reviews of their book, but several I’ve read entirely misstate what was actually written, the old straw man fallacy of inventing something that they didn’t say and shooting it down.  And their attitude is not at all “we’re right, you’re wrong”, no, quite the opposite.  They’re hoping to stir up fruitful avenues of inquiry, different and more meaningful ways of looking at the past, and my hope is that when the energy crisis brings civilization down, new societies can use this book as an inspiration for how to avoid authoritarian kings, brutal agricultural societies, and more.

Dawn of Everything Introduction

Preface.  It is likely that all world oil, both conventional and unconventional, peaked in 2018. The good news is that this means there isn’t enough carbon left to turn the world into a hothouse extinction, though for centuries the planet will be plenty miserable with rising sea levels, heat waves, and crazy weather lowering crop production.  Fossil decline also means we won’t be able to get every last fish out of the oceans, erode topsoil and turn the world into a desert, cut down all the (rain)forests and continue to pollute land, air, and water with toxic chemicals.

But after this calamity occurs, the book “Dawn of Everything” offers great hopes based on past societies of our ability to create far better ways of living and has dozens of examples of how people did so in the past.

When Earth has far fewer people, it will be possible for people to flee slavery, war, hunger, autocrats and more to start their own society or join one with more freedom. In the past politically aware people in tribes and cities designed their governance and way of life to avoid getting their food exclusively from agriculture and losing their freedom to autocratic kings.

Electric Swarm Tractors

Optional cab can be added on to the Sesam 2 (aka GridCON 2)

Preface.  In both my books Life After Fossil Fuels: A Reality Check on Alternative Energy & When Trucks Stop Running: Energy and the Future of Transportation, I write that since most “renewables” generate electricity (i.e. wind, solar, nuclear, hydropower, compressed air energy storage, batteries, geothermal, fusion, etc), then clearly what most needs electrification are agricultural vehicles and equipment to create the fuel that powers us.

John Deere to the rescue. They’ve created an electric tractor that can till soil for cultivation (Vincent 2022). The John Deere Sesam 2 (also known as GridCON 2) is an 8.5 metric ton automated electric tractor with 1,000 kWh of energy storage and 500 kW (680 hp) of power. It comes with a 1-kilometer-long cable (max 2.5 kV/300 kW) which rolls on and off automatically. The electric power unit delivers 100 kW (136 HP) to the wheels, and 200 kW (272 HP) to power additional machinery.  It is driven to the field with a wireless remote control and then the farmer can use a computer to tell the tractor what to do and which paths to take.

The next version, the 8R, will have a power line of 3,000 meters, 8 kV, 1000 kW and be able to operate in swarms. What’s that?  See this video: https://www.youtube.com/watch?v=fzl3wkkKtoA).

So you ask, why have five or more 3,280 feet of cables strung between half a dozen tractors that could get snarled and quite heavy as well?  It’s because batteries would be far too heavy, permanently compressing soil and reducing crop production (some other models of these electric tractors use treads like tanks do to spread the weight out).

Heavy batteries weigh enough to compact soil and reduce future harvests. With their weight problem, electric tractors very well could end up stuck in the mud.  Diesel farm equipment is already compacting soils in some areas that yields are reduced by over 60%, and even permanently (McGarry and Sharp 2003; Drewry et al. 2008; Sidhu and Duiker 2006; Håkansson and Lipiec 2000). A farm tractor can weigh 60,000 pounds, compacting the soil and making it hard for roots to get water and air. That is 30 times more weight than a draught horse, This is especially causing erosion on the half of America’s cropland where corn and soybeans are grown because the rows are so wide that heavy harvesting equipment that compacts and pulverizes soil into a fine powder that is more easily eroded and blown or washed away (RCN 2011; Mathews 2014).

Worldwide, researchers estimate that combine harvesters may be damaging 20% of the land used to grow crops they’ve grown so heavy — about 36,000 kg (79,000 pounds) in 2020 versus just 4,000 kg (8,800 pounds) back in 1958. Compaction makes it hard for plants to grow roots, draw up nutrients, and makes land more likely to flood, harming productivity for decades (Briggs 2022, Kelly 2022).

The 8R uses six pairs of AI stereo cameras, with help from computers, data gathering, and satellite imagery.  Just one of the tractors, and remember, it’s proposed that many be used at once, is estimated to cost over $600,000 and is designed for big farms, which will provide the electricity themselves with solar, wind, and manure digesters (Estes 2022).

Since there will be times when the AI is confounded and stops until told what to do, images will be sent to a call center and an app will alert the farmer who can view the images and decide what to do (Vincent 2022).

But don’t hold your breath, John Deere says that their swarm tractor technology will not be produced for several years due to hurdles such as infrastructure, farm layouts, energy provider billing models, and laws and regulations.

John Deere Autonomous battery electric tractor in action: https://www.youtube.com/watch?v=kHnMPIOqzTE

But there are many obstacles to overcome:

  1. The batteries, even though smaller due to the cables, would still be so heavy that they could compact the soil and reduce future crop production
  2. The batteries would need to spend so much time recharging that crops might not be planted or harvested in the narrow window of time available
  3. Battery electric tractors/harvesters are prohibitively expensive
  4. They would only last as long as natural gas (NG) did, since once NG runs out the electric grid will come down in most places most of the time, since other forms of energy storage — compressed air, battery, and hydropower don’t scale up or even exist in many regions.
  5. Mining uses 10% of world energy (TWC 2020). Electric tractors require the mining of rare earth, platinum and other scarce metals at a time when petroleum is declining (world oil production peaked in 2018). Mining is also the most polluting industry on earth, destroying ecosystems, biodiversity, and rainforests, potentially affects 50 million square kilometers, 37% of Earth’s land (minus Antarctica) (Kleijn et al. 2011; PEBI 2016; Hickel 2019; Sonter et al. 2020; Pitron 2020).
  6. Declining energy will also make the precision needed to make microchips, computers, tractors and more for electric tractors out of reach (Winchester 2018). So at a time when we need to simplify and consume less, electric tractors that only the largest industrial farms can afford rather than many many small organic family farms is the wrong direction.
  7. If the electricity comes from the electric grid, is there enough power out in the country? Most power generation and heavy duty transmission lines are near cities, with very few thin electric wires extending out into the country
  8. If the power is generated at the farm with solar, wind turbines, and manure digesters, how much will that cost, how much land will that take, and how long will it take to charge the tractor batteries?

Most telling of all are the farmers comments:

  1. I hope we can produce enough natural gas to generate the electricity to charge that thing!
  2. you want to go with no fuel just get a good team of horses
  3. If farmers don’t see this as a threat, they probably didn’t see massive corporate farms as a threat either.
  4. If I pay cash for it, am I allowed to put air in the tires or do I need to have it towed to the dealer?
  5. A couple of things here: who checks the seed depth when planting? How many years do the batteries last? What do replacements cost?
  6. How many hours are the batteries good for?
  7. I want to see it working steep ground, and 25% tire wear left
  8. Would’ve liked to see how fast it could go with the tillage gear working as at the speed it was going it would take all year to work up 1 big cropping farm.
  9. Wow that thing moves as fast as a snail
  10. I’d like to see how fast that electric meter is spinning when its charging
  11. Case international had a similar thing back in 2016 but it was just a tractor with no cab but it was all autonomous. I’m pretty sure it became of nothing, cuz never heard about after its debut.
  12. You can’t get parts for equipment now can you imagine how difficult it’s gonna be for parts from this thing and then on top of it really Long way to go with the technology
  13. So if it hits a rock or root that binds while plowing does it continue to tear the disks and plow up or does it stop? Is it going to tell you when you break a plow point, or a mold board?
  14. Some implements need to run at speeds of 10-13 mph for proper tillage.
  15. Bad enough that rare earths from around the planet are stolen to create such “wonderful” advancement. Why not try farming small; that might provide work and health and wellbeing for all. Shit, I forgot… that doesn’t matter so long as there’s profit to be made!
  16. I want to see it travel more the 3 mph with a 50 ft chisel. Our even move
  17. what happens when your sprayer has a blocked nozzle ??
  18. all this electric powered vehicle stuff is just awesome and absolutely needed but it will be forever before a decent, reliable, relatively cheap and environmentally safe battery(s) are invented. All the electric vehicles being built now are built with little regard to the cost of replacement battery(s) and impact on the environment before and after the batteries are used up. And there are probably dead electric vehicle batteries already piling up somewhere on the planet now.
  19. Imagine watching a rain storm roll in waiting for this slow ass thing crawl over 7 acres/hour lol
  20. Maybe it can tow a diesel generator around to charge it while it works 😉 The supposed efficiency of an electric motor simply ignores that fact that another engine somewhere was working to charge the battery so it is at least 50% inefficient right off the bat.
  21. The last thing I want is to be in a glass cab that low to the ground around flying rocks and idiot drivers while moving that from field to field
  22. Definitely a moving target for the pissed off farm employees that lost their jobs lol
  23. Why didn’t they show it turning at the end of the row?
  24. How long before one has a program glitch and it takes out half a mile of fence?
  25. Sure would love to see this thing stop and change a plow point or shear bolt after hitting a rock or clean out a sprayer nozzle when one stops up or stop and clean seed tubes and meters out when any of that happens while planting and we all know the problems never end when planting, problems that a person needs to address.
  26. If it cost 20K to replace the battery in a Tesla, what is it going to cost in this?
  27. The snow would be falling before this slow-poke tractor finished spring work. There is a reason why the don’t show the tractor driving at the normal speeds of diesel tractors… Such speeds would suck the batteries dead before it could make one round around a 100 acre field.
  28. The more complicated something is, the more maintenance it requires and more things to break.
  29. Lets say we are using an average of 200kw (270hp) for 12 hours in order to till our land, thats 200,000watts multiplied by 12 hours, that results in a total of 2,400 kilowatt hours of battery capacity in order to last the whole time, the largest battery on an electric car in production right now is 100kwh, so unless it is 24 times the capacity of that then the battery will not last, this is assuming 100% efficiency with the electric motors and no energy lost through the tyres, drivetrain or through rolling resistance, so how is this viable unless the battery is really that big, but then you get to seeding or tillage when you need to run 24 hours a day, then what?
  30. I’m glad I’m old and will die soon because people think electric vehicles are the way to save our planet, but where does electricity come from? Coal, gas, and nuclear energy. Sounds like we are trading one “evil” for another and solving absolutely nothing.
  31. When the day arrives that electricity is cheaper than fossil fuels, only then will this be a noteworthy development. Until that time, it is a waste of money.
  32. What’s the point if it still has to be controlled by a person?
  33. It only does two passes and needs to be recharged? lol. Do you have a Cat generator to charge it on the fly?
  34. Seriously, you are 25 miles from your shop working in the field. Your tractor needs charging. I guess you bring out your 50kw diesel generator out to change it all night. Am I missing something here?
  35. No emissions locally despite monstrous diesel generator at edge of field?
  36. Unless JD allows right-to-repair then forget it.
  37. Seems like a cool idea… but isn’t the whole value of a tractor is that its versatile and can be used for many applications? seems like a very limited set of applications and probably comes with a steeper price
  38. Isn’t it bad enough buying a piece of equipment and you have to have a technician come out and trouble shoot the thing with patented program just to find out what sensor out of 200 might have failed? Basically you never own the damn thing because you will always be tethered to the parent company
  39. When it breaks down starts on fire you lost that field for good. The fire will never go out. Your land will be toxic.
  40. Great idea until it wrecks itself, wrecks a fence, gets stuck in a ditch, runs onto a road, or kills someone.
  41. It won’t even plough a 50 acre field before it needs charging
  42. What if someone computer hacks this thing. Could do a lot of damage.
  43. Good lord. Why??? Do you know how much electricity it’s gonna take to charge that thing overnight or between jobs. And I guarantee you the machine costs at least $200,000.
  44. Looks extremely impractical and an environmental disaster!
  45. If you had the money it took to buy that you could retire and not farm!
  46. That’s for them 3-piece suit farmers like bill gates
  47. Electric motors are amazing for torque BUT Electric vehicles are not clean. Batteries raw materials are mined in Africa, Chile and China and that’s just the beginning. Say ten years down the line the battery will of at least dropped 25% in capacity or worse. That’s a new battery and costs as much as a new unit. This is far from a green pursuit.
  48. Looks real heavy and has no brain to see a waterway or a wet spot so will go ahead and get stuck any way and really bury itself in and keep going until it is out of power. Would only be used on large farms where no hills and can go for a long time. Would be worthless if you had to charge it for more than 15 minutes during harvest or planting season. That’s about how long it takes to fuel and reload seed now. Would hate to shut down for hours just to recharge. Especially when the rain is coming in the next day and you have to finish before it.
  49. electric cars, trucks, and tractors have the same or more of a foot print then gas or diesel
  50. pulling an 80 foot drill @ 3000acres you would need about 12 electric tractors — it doesn’t make financial sense
  51. You thought tangled wrapped up hydraulic hoses is bad, Wait until you have high electricity cables wrapped up…basically a scaled up garden tiller with an extension cord you have to drag around

Neighborhood councils to cope with energy decline

I’m reading “The Dawn of Everything: A New History of Humanity” which is one of the best books I’ve read in years, and a very hopeful one – this 700 page book is full of evidence that agriculture, capitalism, slavery, greed, and the unfair distribution of wealth we have today globally are not inevitable. There is no inevitable evolution of tribe to chiefdom to monarchy to state.  Better societies once existed and might in the post carbon future. Plus the latest on dozens of new archeological sites found in the past few decades of forgotten civilizations.

French Jesuits and other explorers recorded the ideas of natives before they were destroyed by the onslaught of settlers.  Their insights, political sophistication, and understanding of their cultures were written up into best sellers in Europe, and Rousseau and other philosophers stole their ideas without attribution that gave rise to our modern ideas about freedom, egalitarian societies and more.

Today with 8 billion people, the planet is full, more than full, it isn’t possible to travel so easily as it was before fossil fueled civilizations and find a better tribe or start your own experiment.

And to my surprise, travel was possible in the past. In America, sign language allowed natives to travel widely even if they didn’t speak the tongue of the villages they encountered, and it vastly expanded the ability to trade goods over long distances. The same was true in Australia, see Bruce Chatwin’s amazing book “The Songlines“.

People throughout time and places have always been conscious political actors.  Another aspect of this book that gives me hope for the post fossil fuel world is that many societies deliberately rejected agriculture as their only sustenance, perhaps growing food part of the time seasonally, but then moving to hunting and gathering grounds another time of the year, often with huge celebrations of thousands of people.  Burning Man is not new…

People treasured freedom above all. The freedom to move somewhere else, the freedom to not obey commands.  In some of the quotes of native americans, they were horrified by European culture. For example:

Mi’kmaq natives in Nova Scotia, who had lived for some time next to a French fort said they ‘considered themselves better than the French: “For,” they say, “you are always fighting and quarrelling among yourselves; we live peaceably. You are envious and are all the time slandering each other; you are thieves and deceivers; you are covetous, and are neither generous nor kind; while as for us, if we have a morsel of bread we share it with our neighbor.”  And consequently the Mi’kmaq insisted they were as a result, richer than the French. Yes the French had more material possessions, but they had other, greater assets: ease, comfort and time.

And like the Mi’kmaq, the Wendat were particularly offended by the French lack of generosity to one another: ‘They reciprocate hospitality and give such assistance to one another that the necessities of all are provided for without there being any indigent beggar in their towns and villages; and they considered it a very bad thing when they heard it said that there were in France a great many of these needy beggars, and thought that this was for lack of charity in us, and blamed us for it severely.’

The Wendat were also unimpressed by French habits of conversation. One Frenchman was surprised and impressed by the Wendat eloquence and powers of reasoned argument, skills honed by near-daily public discussions of communal affairs; while the Wendat often remarked on the way Frenchmen seemed to be constantly scrambling over each other and cutting each other off in conversation, employing weak arguments, and overall not showing themselves to be particularly bright. People who tried to grab the stage, denying others the means to present their arguments, were acting in much the same way as those who grabbed the material means of subsistence and refused to share it; it is hard to avoid the impression that Americans saw the French as existing in a kind of Hobbesian state of ‘war of all against all’.

This book is too huge to do a review. In this post I want to cover just a small part of it, of how people deliberately avoided kings and authoritarian leaders by governing with councils.

So no need for kings. But it’s complicated. Many of the large towns that have been recently found weren’t occupied year-round.  The past was full of  festivals, often spiritual in nature, where thousands of people gathered and then dispersed.  But some of these cultures, some of the time, did have rulers during the festival time, but even so, people still had plenty of freedom.

Before moving on to how councils might be one of the ways to cope with energy decline, consider rulers whose scope of power was absolute — but also very limited. And how councils could try to contain such a leader if it happens.

This book gives me great hope that after energy decline, we can reinvent societies to have more freedom, give women the political and economic power they once had, and not return entirely to agriculture and consequent loss of freedom and often slavery and brutal leaders as Scott writes about in Against the Grain (the authors point out that Scott never says this is inevitable in his book).

Kings who could only kill

[The authors posit there are three aspects to state power: The control the knowledge, the right to kill, and a bureaucracy to enforce commands.  Here they give one of many examples where a king has the right to use violence with impunity but doesn’t control knowledge or have the bureaucracy to exert their will over the territory or competitors to deal with]

French accounts of the Natchez of southern Louisiana in the 18th century seem to describe this sort of arrangement.  The Natchez are the only undisputed case of divine kingship north of the Rio Grande. Their ruler enjoyed an absolute power of command that would have satisfied a Sapa Inca or Egyptian pharaoh; but they had a minimal bureaucracy, and nothing like a competitive political field. As far as we know it has never occurred to anyone to refer to this arrangement as a ‘state’.

A French Jesuit, Father Maturin Le Petit, gave an account of the Natchez in the early 18th century. He was especially struck by their religious practices which revolved around a settlement called the Great Village, with two great earthen platforms separated by a plaza. On one platform was a temple; on the other a kind of palace, the house of a ruler called the Great Sun, large enough to contain up to 4,000 people, about the size of the entire Natchez population at the time.

The temple, in which an eternal fire burned, was dedicated to the founder of the royal dynasty. The current ruler, together with his brother ‘the Tattooed Serpent’ and eldest sister ‘the White Woman’, were treated with something that seemed very much like worship. Anyone who came into their presence was expected to bow and wail, and to retreat backwards. No one, not even the king’s wives, was allowed to share a meal with him; only the most privileged could even see him eat. What this meant was that members of the royal family lived out their lives largely within the confines of the Great Village, rarely venturing beyond except for major rituals or times of war.

French observers were particularly struck by the arbitrary executions of Natchez subjects, the property confiscations and the way in which, at royal funerals, court retainers would – often, apparently, quite willingly – offer themselves up to be strangled to accompany the Great Sun and his closest family members in death. Those sacrificed on such occasions consisted largely of people who were, up to that point, immediately responsible for the king’s care and his physical needs, including his wives who were always commoners.  Many went to their deaths voluntarily, even joyfully. One wife remarked how she dreamed of finally being able to share a meal with her husband in another world.

A paradoxical outcome was that, for most of the year, the Great Village was largely depopulated. As noted by Father Pierre de Charlevoix, ‘The reason which I heard for this is that the Savages, from whom the Great Chief has the Right to take all they have, get as far away from him as they can; and therefore, many Villages of this Nation have been formed at some Distance.’

Away from the Great Village, ordinary Natchez appear to have led very different lives, often showing blissful disregard for the wishes of their ostensible rulers. They conducted their own independent commercial and military ventures, and sometimes flatly refused royal commands conveyed by the Great Sun’s emissaries or relatives. Archaeological surveys of the Natchez Bluffs region bear this out, showing that the eighteenth-century ‘kingdom’ in fact comprised semi-autonomous districts, including many settlements that were both larger and wealthier in trade goods than the Great Village.

The Great Sun was said to be descended from a child of the Sun who came to earth bearing a universal code of laws, among the most prominent of which were proscriptions against theft and murder. Yet the Great Sun himself ostentatiously violated those laws on a regular basis.

The problem with this sort of power from the sovereign’s vantage point, is that it tends to be intensely personal. It is almost impossible to delegate. The king’s sovereignty extends about as far as the king himself can walk, reach, see or be carried. Within that circle it is absolute. Outside it, it attenuates rapidly. As a result, in the absence of an administrative system (and the Natchez king had only a handful of assistants), claims to labor, tribute or obedience could, if considered odious, be simply ignored.

Even if one does develop an administrative apparatus (as they of course did), there is the additional problem of how to get the administrators actually to do what they’re told – and, by the same token, how to get anyone to tell you if they aren’t.

French saw the Natchez court as a sort of hyper-concentrated version of Versailles. On the one hand, the Great Sun’s power in his immediate presence was even more absolute (Louis could not actually snap his fingers and order someone executed on the spot); while on the other, his ability to extend that power was even more restricted (Louis did, after all, have an administration at his disposal, though a fairly limited one compared to modern nation states). Natchez sovereignty was, effectively, bottled up.

The Natchez case illustrates a more general principle whereby the containment of kings becomes one of the keys to their ritual power. Sovereignty always represents itself as a symbolic break with the moral order; this is why kings so often commit some kind of outrage to establish themselves, massacring their brothers, marrying their sisters, desecrating the bones of their ancestors or, in some documented cases, literally standing outside their palace and gunning down random passers-by. Yet that very act establishes the king as potential lawmaker and high tribunal, in much the same way that ‘High Gods’ are so often represented as both throwing random bolts of lightning, and standing in judgment over the moral acts of human beings.

For most of history, this was the internal dynamic of sovereignty. Rulers would try to establish the arbitrary nature of their power; their subjects, insofar as they were not simply avoiding the kings entirely, would try to surround the godlike personages of those rulers with an endless maze of ritual restrictions, so elaborate that the rulers ended up, effectively, imprisoned in their palaces.

So far, then, we have seen how each of the three principles we began with – violence, knowledge and charisma – could, in first-order regimes, become the basis for political structures which, in some ways, resemble what we think of as a state, but in others clearly don’t. None could in any sense be described as ‘egalitarian’ societies – they were all organized around a very clearly demarcated elite – but at the same time, it’s not at all clear how far the existence of such elites restricted the basic freedoms we described in earlier chapters.

There is little reason to believe, for instance, that such regimes did much to impair freedom of movement: Natchez subjects seemed to have faced little opposition if they chose simply to move away from the proximity of the Great Sun, which they generally did. Neither do we find any clear sense of the giving or taking of orders, except in the sovereign’s immediate (and decidedly limited) ambit.

For some readers, the idea of a dead monarch sent off to the afterlife amid the corpses of his retainers might evoke images of early pharaohs. Some of Egypt’s earliest known kings, those of the First Dynasty around 3000 BC, were indeed buried in this way. But not just Egypt: In almost every part of the world where monarchies established themselves, from the early dynastic city-state of Ur in Mesopotamia to the Kerma polity in Nubia to Shang China. There are also credible literary descriptions from Korea, Tibet, Japan and the Russian steppes. Something similar seems to have occurred as well in the Moche and Wari societies of South America, and the Mississippian city of Cahokia.

We might do well to think a bit more about these mass killings, because most archaeologists now treat them as one of the more reliable indications that a process of ‘state formation’ was indeed under way. They follow a surprisingly consistent pattern. Almost invariably, they mark the first few generations of the founding of a new empire or kingdom, often being imitated by rivals in other elite households; then the practice gradually fades away (though sometimes surviving in very attenuated versions, as in sati or widow-suicide among largely kshatriya – warrior-caste – families in much of South Asia). In the initial moment, the practice of ritual killing around a royal burial tends to be spectacular: almost as if the death of a ruler meant a brief moment when sovereignty broke free of its ritual fetters, triggering a kind of political supernova that annihilates everything in its path, including some of the highest and mightiest individuals in the kingdom.

This sovereign power in tiny kingdoms and miniature courts always existed with a core of blood relatives and a motley collection of henchmen, wives, servants and assorted hangers-on. Some of these courts appear to have been quite magnificent, leaving behind large tombs and the bodies of sacrificed retainers. The most spectacular, at Hierakonpolis, includes not only a male dwarf (they seem to have become a fixture of courtly society very early on), but a significant number of teenage girls, and what seem to be the remains of a private zoo: a menagerie of exotic animals including two baboons and an African elephant. These kings give every sign of making grandiose, absolute, cosmological claims; but little sign of maintaining administrative or military control over their respective territories.

In summary, the Natchez Sun, as the monarch was known, inhabited a village in which he appeared to wield unlimited power. His every movement was greeted by elaborate rituals of deference, bowing and scraping; he could order arbitrary executions, help himself to any of his subjects’ possessions, do pretty much anything he liked. Still, this power was strictly limited by his own physical presence, which in turn was largely confined to the royal village itself.

Most Natchez did not live in the royal village, indeed, most tended to avoid the place, for obvious reasons.  Outside it, royal representatives were not treated seriously. If subjects weren’t inclined to obey these representatives’ orders, they simply laughed at them. So while the court of the Natchez Sun was not pure empty theatre – those executed by the Great Sun were most definitely dead – neither was it the court of Suleiman the Magnificent or Aurangzeb.

There are no signs of Kings, violence, walls built for defense and protection in dozens of new towns and cities that have been discovered the past few decades.  Greece was not the first democratic state, it appears that civilizations were ruled by local councils.  Those examples would take hundreds of pages to elaborate on, so let me cut to the chase, what it might mean for our future.

I’m also reading Bill Bryson’s outstanding 2018 book “The Body: A guide for occupants”. In the pandemic chapter he talks about how scientists worry the about bird flu, since these can kill up to 60% of people who catch it. We were lucky with covid-19, the death rate wasn’t high enough to prevent most essential workers from showing up. But in a bird flu, or other pandemic with even a 10% death rate, society would grind to a halt.  No one would go to work. Stores would run out of food. Fires burn out of control.

No doubt inspired by both Graeber and Bryson’s books, I dreamt the bird flu had arrived, and to cope,  the progressive neighborhood group I’m part of got together and went door to door to enlist people to grow food, especially potatoes. If a household was unwilling then we asked if they’d let others grow food in their yard in exchange for getting half of what was produced, and found people willing to do so.  All within the neighborhood to keep trust high.  We also asked for any extra potatoes or seeds to start growing them immediately to share with the neighborhood.

Ideally we’d have already started these councils to cope with overshoot, and be doing many projects, such as planting fruit and nut trees, installing water storage tanks that also insulate homes, and much more, explored at greater depth in Transition Towns, permaculture, and organizations such as resilience and postvcarbon.org.  Local cities, the state, and federal government would work with neighborhood councils to supply seeds, water tanks, food, and more.  Today cities have task forces to make recommendations, perhaps these would become councils or existing departments given more power to give citizens more control in governance and hold chaos and violence at bay.

And then this morning, I read about dreams in “The Dawn Of Everything”.  Here’s how one Native American tribe saw them:

In 1649 Father Ragueneau wrote that the Wyandot people of Lake Ontario believed that secret desires are communicated in dreams in an indirect, symbolic language, difficult to understand, so they spent a great deal of time trying to decipher the meaning of one another’s dreams and consulting specialists. This was long before Freud wrote about dreams in 1899, seen by many as one of the founding events of 20th century thought.

‘Dream-guessing’ was often carried out by groups, and sometimes in the winter a town devoted itself to organizing collective feasts and dramas to make some important man or woman’s dreams come true.

Most traditions are not documented. Many other societies were entirely destroyed, or reduced to traumatized remnants, long before any such records could be written down. One can only wonder what other intellectual traditions might have been forever lost.

Can we eat enough fried food for biodiesel to keep trucks running?

Fatberg from London sewer

If the U.S. can’t make enough biodiesel from plants, then the question becomes: Can we step up our fast-food game? Can we eat more French fries?  Biodiesel is already made from used cooking oil (11.5% of all U.S. biodiesel), animal and other fats (5%).

We could also scrap other products made from vegetable oils and animal fats and shift them to biodiesel. Products like soap, paint, varnish, vinyl plastics, lubricants, livestock and pet food, clothes, rubber, detergents, candles, rust inhibitor, shampoo, caulking, disinfectants, epoxies, electrical insulation, metal casting, plasticizers, and more (Murphy 2004). Who knew we are swimming in vegetable oils and animal fats!

Using restaurant waste grease helps stop the problem of it being illegally dumped into the sewage system, which can result in severe blockages. Once restaurant grease clogs a sewer, sewage may back up into the facility, shutting it down until the sewage pipe is cleaned. In London, sewers were clogged with a record-breaking fatberg that weighed 140 tons. Picture that!

Currently hotels and restaurants generate three billion gallons of waste cooking oil, though most ends up in landfills or down the drain rather than biodiesel (EPA 2017). That is a gob of grease, but a far cry from the 46 billion gallons of petroleum diesel consumed.

We will just have to belly up and eat a lot more deep-fried food. At last, we’ll have a good excuse to eat fried chicken and French fries with no guilt! If anyone can eat more fast food, it’s Americans. Already 72% of adults are overweight or obese (CDC 2016). We’re really good at eating. Spin eating fried food as a patriotic duty and it will be the most popular government edict ever.

Believe it or not, there are statistics on our personal grease consumption. About four gallons of used cooking oil and trap grease are generated per person per year (NREL 1998). Thank you for that important information NREL! With 329 million people, that’s about 1.3 billion gallons. Americans are going to have to eat at least 15 times more fast food to nudge biodiesel production to half of oil diesel consumption. Though obesity may shorten American lifespans, it won’t be in vain. After death, excessive human fat can be rendered to make even more biodiesel to allow us to continue to our nonnegotiable way of life. Plus, liposuction clinics could harvest fat periodically. Americans could eat as much as they liked all the time, and we’d forever end the pain of dieting (Squatriglia 2007).

It’s too bad truck drivers running on empty can’t just pull up to a fast food joint and say fill ‘er up while eating fried food to keep the virtuous biodiesel cycle going. Sadly, unrefined vegetable oil, grease, or animal fats would harm their engine. Restaurant grease has to be trucked to a biodiesel refinery, pretreated to remove dirt, meat scraps, breading, and water, phospholipids and plant matter degummed. Making biodiesel from cooking oil and trap grease is especially tricky because of their free fatty acids, which tend to react with catalysts to produce soap instead of biodiesel.  The more soap made, the more soap and methanol that need to be removed and discarded, with some of the methanol and glycerol disposed of as hazardous waste.  And to think this glob all began with French fries!

Conclusion. Seriously, Americans aren’t going to be able to eat enough fast food. Seriously, we are already too heavy. In an energy scarce world, it will be far better and healthier to live close to work and use muscle power, walking and bicycling, to get there. Seriously. Not that there will be any choice…

Why it is hard to replace diesel with biodiesel

Biodiesel is the great hope, our main hope, the only renewable fuel of all the many options, and the closest to the diesel essential for rail, trucks, and ships to do the actual work of civilization.

The U.S. produces over a billion gallons a year of biodiesel in the U.S. Our biodiesel is made from 95% vegetable oils (68% soybean, 16% corn, 11.4% canola) and 5% animal fats and grease (EIA 2019a).  About one tenth of biodiesel comes from used cooking oil.

No other biofuel can substitute for diesel fuel besides biodiesel, for reasons explained here and a dozen chapters in Life After Fossil Fuels: A Reality Check on Alternative Energy. Not ethanol from corn, cellulose, or kelp. Nor biodiesel from algae, finite liquefied coal (CTL), hydrogen, ammonia, power-to-gas, methane hydrates, natural gas, or oil shale.  And while I’m at it, nor can transportation be electrified with batteries or overhead wires.

Biodiesel hits the ball out of the park. It is renewable. Trucks can run on it. It is commercial.

Scale is an issue though.  Globally, 27.95 million barrels of petroleum diesel are consumed per day, but only 655,000 barrels of biodiesel (BP 2020). Biodiesel production would need to be scaled up 43-fold after oil decline.

And there’s not enough land, too much soil erosion and aquifer depletion, climate change, drought, and more limiting soybean and other oilseed production.

The U.S. burns 46 billion gallons of petroleum diesel a year. It makes just 1.8 billion gallons of biodiesel annually, 25 times less than needed (EIA 2018, EIA 2019).

It bears repeating: 68% of U.S. biodiesel comes from soybeans. Even if all 87.2 million acres of soybeans, grown on a quarter of America’s cropland, were used to make biodiesel, just 5.7 billion gallons could be produced. But that isn’t likely, since soybeans are also in demand for livestock feed, cooking oil, baked goods, soy milk, tofu, industrial lubricants and other goods (NCSPA 2019).

Corn can yield 18 gallons of biodiesel per acre. Soybeans can yield 65 gallons of biodiesel per acre.  What accounts for this difference?  Not crop yield. Corn yields 177 bushels per acre and soy just 52 bushels. Rather, it is fat content. Corn is 4% fat whereas soy is 20% fat. You need fat to produce biodiesel.  Despite its low-fat content (four percent) and because of its high yield, corn manages to contribute 16% of annual U.S. biodiesel production in 2019.

For biodiesel, peanuts would be better than either corn or soybeans. Peanuts are half oil and can yield 123 gallons per acre. But they grow only in the most humid areas of seven Southeastern states. Nor do other oil seed crops scale up.

Besides ramping up production, distribution will need to be scaled up too. There are 168,000 gas stations but only 300 where 20% biodiesel (B20) or above is available (AFDC 2020).

Biodiesel requires a lot of water. The water footprint of biodiesel from seed to harvest to delivered fuel is vast, not good at a time of increasing drought, population growth, and aquifer depletion. Soy biodiesel requires 13,676 liters (3613 gallons) of water per liter of biodiesel produced and corn ethanol 2,570 liters (725 gallons) (Gerbens-Leenes 2009). Petroleum gasoline has a much smaller footprint, on average just 4.5 gallons of water per gallon of gasoline produced Wu et al. (2018).

Water is a problem both coming and going. Plants end up as 90-95% water. Removing this water to make fuels takes a lot of energy, but has to be done to avoid corroding and clogging diesel engines (Racor 2013).

Bad chemistry.  Making fuels from plants is challenging because their chemistry differs from crude oil, which is nearly all hydrocarbon chains of 82-87% carbon and 12-15% hydrogen.

Plants have hydrocarbons, but are also chockablock with oxygen, nitrogen, phosphorus, potassium, calcium, magnesium, zinc, sulfur, chlorine, boron, iron, copper, manganese and more.  Good for vitamin pills, bad for trucks, these elements need to be removed to make biodiesel, adding to cost and energy.

Even then, plant oils are so different from petroleum diesel oil that it is hard to match the specifications of the diesel fuel standard. This standard, ASTM D 975, specifies energy density, oxidative and biological stability, lubricity, cold-weather performance, elastomer compatibility, corrosivity, emissions (regulated and unregulated), viscosity, cetane number, distillation curve, ignition quality, flash point, low-temperature heat release, metal, ash, and sulfur content, water tolerance, specific heat, latent heat, toxicity, and ash and sulfur content. It seems nearly miraculous that crude oil can be refined to conform to all these specifications. And it’s a lot to ask of a soybean.

Unlike standard diesel, biodiesel is biodegradable, and thus needs to be used within 45 to 90 days.

Why such extensive specifications for diesel? Fuel outside the specifications can harm diesel engines by gelling up in cold weather or acting as a solvent, releasing rust and other contaminants that plug filters and fuel injectors, and more (Bacha et al. 2007, Schmidt 2007).

That’s why many heavy-duty engine manufacturers have warranties that don’t allow biodiesel, though B5 (5% biodiesel / 95% petroleum diesel) is often fine. Some warranties prohibit B20 to B100.

Distribution is a problem too. Biodiesel can’t travel in oil or gas pipelines, because, like ethanol, biodiesel is a good solvent, and able to pick up water and impurities that can harm engines (APEC 2011).  It is five to 20 times more costly to move biodiesel by rail or truck than were it possible to use pipelines (Curley 2008).

A barrel of crude oil is only 10-15% diesel in the U.S.  It will take decades to build thousands of biodiesel factories, shift more cropland to oilseed crops, modify truck engines to burn B100, and build pipelines that can handle biodiesel.

If we could convert more crude oil to diesel, we could buy time for a transition from diesel to biodiesel. But only about 10 to 15 percent of a barrel of crude oil can be refined into diesel. A barrel of crude oil makes dozens of other useful products. As crude oil is heated at the refinery, fractions split off. The first to go are lighter hydrocarbons for plastics, then propane, gasoline, kerosene for jets, diesel, heavy oil, and asphalt.

The EROI of biodiesel is low, roughly 1.3 to 1.9 (Pimentel 2005, Hill et al. 2006), far short of the 10 to 14:1 needed to keep civilization as we know it continuing (Lambert et al. 2014).

Conclusion. Biodiesel is significantly more expensive to make than petroleum diesel, so like ethanol, its existence is almost entirely due to federal policies such as the RFS biomass-based diesel and biodiesel production tax credits, excise tax credits, small biodiesel producer credits, and the RFS mandate that requires specific amounts of biodiesel in the overall fuel pool (Schnepf 2013).

Farmers can’t grow enough oilseeds to replace petroleum diesel. But some of it is made from animal fats and grease. That brings us to the next question: Can we eat enough French fries to keep trucks running?

Corn for ethanol & soy for biodiesel tremendously destructive

In the news: Cullen A (2024) Corn Belt fertilizer is killing the Gulf of Mexico. Washington Post. About 30 percent of the nitrogen applied for raising corn is lost to water, and much of it right now is draining off in the spring rise. All that detritus, the tons upon tons of soil with phosphorous mixed in, float downstream past St. Louis, Baton Rouge and New Orleans, suffocating the Gulf of Mexico for the sake of corn, wheat, cotton and rice. They call it the Dead Zone, where almost nothing can live. The shrimp spawning in the brackish Louisiana marshes can’t find their way to deeper water to mature. Smaller shrimp fetch less for the shrimpers. The economic loss from gulf hypoxia is estimated at up to $2.4 billion per year.

It’s a bad combo: Bare Iowa soil in spring. Increasingly extreme weather with torrents of rain. Underground tiles, installed by farmers to help drain their cornfields and keep crops dry, are everywhere now in northwest Iowa — the drainage capacity has doubled since 1980. The effluent from these tiles pours into to the Raccoon River, swelling from the spring flush. The Raccoon runs southeast in Iowa, joins the Des Moines River, then feeds the Mississippi, which feeds the gulf and stunts the shrimp.
Methane is cheap in the gulf, where oil and gas derricks line the horizon. We ship the gas upstream to Iowa, where it is processed into anhydrous ammonia for fertilizer. Farmers inject it in the soil to feed the corn that feeds the hogs that create the phosphorus in their manure. It flushes down the Raccoon all over again.
We hooch nearly half our corn crop not into food or feed but into ethanol for cars, which is why we plant up to the last inch of the creek side and river bank. We wear suspenders with our belts for a bumper crop — we dump manure on top of the commercial anhydrous ammonia to get that next marginal bushel of corn. It’s killing us, or at least killing the gulf.  The Raccoon River ran clean before 1980, when the Farm Bill was changed to maximize production, according to Jerry Hatfield, agronomist and former director of the National Laboratory for Agriculture and the Environment at Iowa State University, and farmers began planting fencerow to fencerow.

 

The Green Gold Rush to make biodiesel has begun in earnest in California. It would not be profitable without subsidies from LCFS credits, federal RIN D5 credits, and  Blenders Tax Credits at $3.32 a gallon, which is enough to cover production costs, according to Van der Wal, biofuel advisor at Stratas Advisors in Singapore.

He said “It’s a mind-boggling amount of money, you will make a lot of money as long as all these subsidies come in.” Without this money, biodiesel is an energy sink, with very low EROI.

Biodiesel competitors already in the market have already locked up much of the tallow, cooking oil, and other resources Marathon and Phillips hope to use (Bloomberg 2021). And California doesn’t grow many soybeans because of water shortages, so importing soy will increase CO2 via transportation emissions here and the CO2 from tractors and trucks in other countries or the U.S.

Corn and soybeans are very destructive to the environment, eroding more topsoil, causing more pollution, global warming, acidification, eutrophication of water, water treatment costs, fish kills, and biodiversity loss than most other crops (Powers 2005, Troeh and Thompson 2005, Zattara and Aizen2019).

Food versus fuel. Over 40% of the corn crop becomes fuel, not food at a time when 43 million Americans need help with food stamps (USDA 2020) and the high unemployment rate from Covid-19 could drive the need for food aid up to over 54 million people (Lee 2020).

Too many pesticides.  Corn and soy are especially destructive because they need a lot of pesticides. Of all pesticide use on crops, corn’s share is 39.5% and soybeans 22% (Mclaughlin and Walsh 1998, Padgitt et al. 2000, Pimentel 2003, Patzek 2004, Fernandez-Cornejo et al. 2014). I don’t want to say they have a drinking problem, but shall we say they have a “dependency problem.”   All these pesticides kill bees, wild bees, and other important pollinators. The neonic pesticides mentioned earlier that are 48 times more toxic to insect life than other chemicals are mainly used on corn and soybeans (DiBartolomeis et al. 2019).

Corn and soy already take up half of U.S. cropland. Corn and soy are grown on over half of America’s 324 million acres of cropland (USDA 2018).  Over half!

Corn can yield 500 gallons of ethanol per acre (NRC 2014, USDA 2019). That sounds like a a lot, but corn fuel is small potatoes. Despite a doubling of corn acreage due to the 2007 federal renewable fuel standard, the 40% of corn grown to make ethanol is a measly 10% of our U.S. gasoline mix. In the case of diesel, 99% of what we use is petroleum diesel, and 1% percent is biodiesel. So even if all 324 million acres of American farmland were planted in corn and soybeans, they’d barely make a dent in transportation fuels while driving food and feed prices higher.

Corn and soy cause the most soil erosion. Corn and soy are 50 or more times more prone to soil erosion than sod crops like wheat, barley, rye, and oats. Why is that? It’s because they are planted in rows much wider than other crops, up to 30 inches wide, a major highway for wind and water to barrel along and take topsoil with them (Al-Kaisi 2000, Sullivan 2004). This is exacerbated by heavy harvesting equipment that compacts and pulverizes soil into a fine powder that is more easily eroded and blown or washed away (RCN 2011, Mathews 2014).

Nevertheless, a corn ethanol goldrush is on. Farmers converted 10 million acres of grassland, shrubland, wetland, and forestland into cropland between 2008 and 2016, with 2.9 million acres for corn and 2.6 million acres for soy (Lark et al. 2018).

Conservation Reserve Program (CRP) lands are protected because they retain water, support pest predators, sequester carbon, and sustain wildlife. CRP land is highly-erodible if farmed. In fact, the government pays farmers not to grow crops on this land. When ethanol subsidies or corn prices are high, CRP land is often converted to corn crops. In 2007, 36.7 million acres were enrolled in the CRP program, today it’s just 21.9 million acres, a loss of nearly 15 million acres.

Using CRP and undeveloped land to grow corn erases the carbon benefits of using ethanol over gasoline (Uri 2000, Tomson 2007, Searchinger et al. 2008, Fargione et al. 2008, Piñeiro et al. 2009).  After the harvest, most farmers leave their soil bare, except for a minority who plant cover crops or leave corn stover on the ground. This naked soil lies unprotected from wind and heavy rain that grab soil, sediment, pesticides, and fertilizer, running away with them.

A lot of soil is lost – 20 to 40 pounds per gallon of ethanol according to Jerald L. Schnoor, professor of civil and environmental engineering at the University of Iowa (NRC 2014).

Since 16 billion gallons of ethanol are produced per year, that’s 160 to 320 million tons of topsoil lost. An acre of topsoil 6-7 inches deep weighs 1,000 tons, so if soil were lost in just one area, as happened in the massive Midwestern floods of 2019 (Philpott 2019, Ippolito and Al-Kaisi 2019), 250 to 500 square miles of topsoil would be strip mined to the subsoil bones below.  But such disastrous floods are uncommon. Usually a fraction of an inch is lost across the 127,800 square miles planted in corn, such a small amount we don’t notice. But year by year, erosion adds up, subtracting from the land. As detailed in Chapter 16, topsoil is eroding all over the world, and affects up to half of America’s agricultural soil, a peril to future food and the environment (Pimentel 2005).

Corn and soybeans are water hogs (sorry pigs). It takes some 3,600 gallons of water to produce enough soybeans to make a quarter gallon of biodiesel, and 680 gallons of water per liter of ethanol (Gerbens-Leenes et al. 2009). You knew that, right? Afterwards, for every gallon of ethanol produced, 12 gallons of noxious sewage effluent are released that need to be treated (Schulz 2007).

Corn ethanol and soy biodiesel are not good options for the arid states of the West. Nor for California. To make just 20% of the 16 billion gallons of ethanol produced a year in the U.S. in California would require over 8 trillion gallons out of the 8.4 trillion gallons of irrigation water now used to grow over 400 kinds of crops. Soybeans would need more water than California has available (Maupin et al. 2014). As it is, field crops like corn, soy, and cotton are draining California’s aquifers more than water intensive alfalfa, truck crops, and fruit and nut crops (Levy et al. 2020). For generations now in California, there have been fights over water between agriculture, cities, the environment, and fisheries (Fingerman et al. 2008). Thank you kindly, but please don’t plant your biofuel plantations in my home state of California!

Corn’s dirty secret – that corn ethanol is not a public good – is well known. Many papers have shown that it takes about one calorie of fossil fuel to make a calorie of ethanol (e.g. Pimentel 2003, Murphy et al. 2010).  This is known even in the halls of the U.S. Congress, which has created a pork barrel for corn and soy farmers.  Both the House and Senate have tried many times to repeal or reduce the amount of ethanol called for in the Renewable Fuel Standard. Yet the federal mandate that U.S. transportation fuels have a minimum volume of biofuel remains. In 2020, the mandate is 11.56% biofuels by volume.  Here is a list of just a few failed congressional reform bills: HR 424 (2011), S 1584 (2015), HR703 (2015), HR 119 (2017), HR 1314 (2017), HR 104 (2019), HR 3427 (2019).  (Source: https://crsreports.congress.gov/product/pdf/IN/IN11353)

More fertilizer, more dead zones. Corn also uses more nitrogen fertilizer than most crops (Padgitt et al. 2000, Pimentel 2003, NRC 2003), and significant amounts of phosphorus. Corn needs a lot of fertilizer because corn plants are quite adept at absorbing nitrogen and storing it in the corn grain.  But unfortunately, much of the nitrogen fertilizer applied doesn’t go into the grain but instead washes away into lakes, rivers and the ocean (NRC 2014).

Fertilizer runoff is also the main culprit causing dead zones such as the 6,000 to 7,000 square miles of water at the mouth of the Mississippi River in the Gulf of Mexico.  Dead zones develop when overloads of nutrients – nitrogen and phosphorus – allow algae to go on a nutrient binge, proliferating to the point they suck the oxygen out of the water. Any fish, shrimp, and crabs in this zone die, especially bottom dwelling fish, shrimp, clams, mussels, and oysters.  Those that live can accumulate algal toxins that concentrate in shellfish, herring, mackerel, and sardines near the bottom of the food chain making them potentially lethal.

Industrial farming is great for jellyfish. Not being harmed, and in fact ballooning in numbers, are jelly fish. They are on the way to dominating the ocean and displacing fish. Despite the fact that they have no backbones! Jellyfish can handle hypoxia (low oxygen levels), love warmer climate-changed oceans, and proliferate thanks to trawling, overfishing, fertilizer and sewage runoff.  We’re tipping the ocean ecosystem to favor jellyfish, possibly permanently. And they’re awfully hard to kill. Chemical repellents, biocides, nets, electric shocks, and introducing species that eat jellyfish won’t do it.  If you shoot, stab, slash, or chop off part of a jellyfish, it can regenerate lost body parts within two days.  Not even the past five major extinction events that killed up to 96% of life on earth drove jellyfish extinct (Gershwin 2013). I couldn’t find a jellyfish cookbook. You could create the first!

Somebody send the Bat Signal!  Healthy topsoil and fresh water are essential for our future national security, indispensable if we are to grow biomass for food, infrastructure, and energy. Yet the U.S. exports 112,000 barrels per day of fuel ethanol causing erosion, water depletion, pollution, and eutrophication of waterways in our own country (EIA 2019).

If only Batman could save us from these polluting, erosion-prone, aquifer draining supervillain crops that take up half our crop land. Better yet, don’t send Batman, send bats to eat crop pests and lower pesticide use. Please write your representatives to repeal the renewable fuel standard and drive a wooden stake through the vampire ethanol industry. We are just trading petroleum for an equal amount of alcohol, with no net effect except losing a huge amount of our most precious resource.  Soil!
