    burn rates

    of all the aforementioned combustibles increase exponentially with pressure, ie. they work best when compressed (gasoline,diesel etc.) or when confined, (smokeless powders, pistol,rifle,etc).

     

    i spend alotta time trying to find pressure curves to fit chamber, barrel, and projectile weight, for an ordained purpose.

    … that I would half expect gun safes to have self-oxidizing gun cartride shells in the vicinity; I might even expect to find oxygen containers in the area; and when all that concrete comes crashing down, making an insulated mess, I might not be too surprised to find steel safes melted similar to what we did in our propane forge. Insulation, plus an over supply of oxygen in a good, steady high-mass-rate-of-flow, plus a good hydrocarbon source can do amazing things.

    I’d be hugely surprised.

    Why?

    Because the amount of smokeless gunpowder in the average pistol round is around 6 grains.  Which means there’s around 1 kg of powder in 2,500 rounds.

    Smokeless powder has an energy potential of 4.6 MJ/kg

    Gasoline has 131.76 MJ/ gallon

    Converting all of that, it means that to have the same energetic (heat) potential as a gallon of gasoline, you’d need more than 75,000 pistol rounds.

    That would about fill a medium sized safe completely.  But let’s be safe and double that.  I’ll grant you 150,000 rounds in a gun safe.

    Do you think you can melt a steel safe, PLUS turn concrete into a molten mess with 2 gallons of gasoline?

    Me neither.   Isn’t data fun?  It cuts out a lot of guesswork and grey zones.

    Also, let’s not hypothesize oxygen tanks, because none have ever been mentioned and so why do that?  Does the ATF also run home-health O2 resupply missions I don’t know about?

    Forming the Worlds We Live or We Map The Territory

    Dave and Eric –

    Another take on reality and our experience.

    In Hierarchy Theory Allen and Ahl separate what is contributed by the physical world from what is contributed by us, observers, in the act of perceiving. The physical world contributes gradients in behavior. That’s it. 

    We contribute all of the rest.

    Via processes involving addition, deletion, and distortion, we build the worlds that we live starting from those gradients in behavior. We name the edges by which a dandelion emerges as a separate thing. We form the levels of classification, by which the dandelion becomes a member of a group called dandelions, and the group gets labeled as a weed, and the weed gets labeled as something to be eradicated. 

    Between edging and levels of organizing and then working with those levels, lots of room for missteps and unfortunate choices. Also lots of room for making more fruitful choices. More useful maps of reality. Even if a given map has edges, contains dragons, and shows cities, but not distributions of animals or cultural beliefs.

    Maps are more or less useful. More is better. Less can be lethal.

    Mapping miscreants: It can be useful to reclassify a weed (or a pharmaceutical executive or The Fed) as an opportunist. That change invites a move in focus from the individual and its characteristics to looking at the environment where opportunities arise for invasions of undesirable characters. And that invites us to consider our role in sustaining it. Levels of organization, of mapping. Our choices, environments, opportunists. Which level will be most effective to focus on?

    Mapping energy: It can be useful to look at fossil fuels not in general, but by mapping in multiple levels. The argument of whether energy drives the economy or the economy drives energy seems like a false argument. Currently available barrels enable certain current economies and not others. The current economy enables obtaining future barrels, which enable a future economy. That is, the barrels enabling the current economy are not the same barrels obtained by that economy. 

    It is challenging to experience the raw gradients in behavior without the added levels of meaning. John Grinder, one of the cofounders of NLP (Neurolinguistic Programming, mentioned by Chris a few weeks ago.) developed an exercise to experience, as far a possible, the physical world. Pairs of people went out into the streets of London and, one at a time, tried to experience splotches of green, red, and yellow rather than ivy leaves; the feel of hard curves underfoot rather than cobble stones; changing sound levels and textures rather than taxi cab horns. The second person was there, of course, to keep the explorer from being hit by a cab. My partner was able to escape his constructed world. I was not.

    I love this perhaps apocryphal story about Picasso riding on a train. The man next to him said that he preferred art that was realistic. Picasso asked the man if he had a picture of his wife. The man pulled out his wallet and proffered a photo. Picasso looked at it and said, “She’s very small, isn’t she?” 

    The map is not the territory. We live the maps. So hard to remember.

    DIY magic forge

    Hey guys, I’ve actually seen this one in action; my son and I forged spice chpper knives!

    It’s a DIY magic forge.

    Kunstler on our common knowledge predicament

    https://kunstler.com/clusterfuck-nation/there-is-no-normal/

    Even the traumas of the 20thcentury’s world wars did not crush that sense of amazing progress, at least not in North America, spared the wars’ mighty wreckage. The post-war confidence of American society achieved a level of in-your-face laughable hubris — see the USA in your Chevrolet! — until John Kennedy was shot down, and after that the delirious moonshot euphoria steadily gave way to corrosive skepticism, anxiety, acrimony, and enmity. My generation, booming into adulthood, naively thought they could fix all that with Earth Day, tofu, and computers, and keep the great wheel rolling down into an even more glorious cybernetic nirvana.

    Fakeout. That’s not where the wheel is going. We borrowed all we possibly could from the future to pretend that the system was still working, and now the future is at the door like a re-po man come to take away both the car and the house. The financial scene is an excellent analog to our collective psychology. Its workings depend on the simple faith that its workings work. So, it is easy to imagine what happens when that faith wavers.

    We’re on the verge of a lot of things coming apart: supply lines, revenue streams, international agreements, political assumptions, promises to do this and that. We have no idea how to keep it together on the downside. We don’t even want to think about it. The best we can do for the moment is pretend that the downside doesn’t exist. And meanwhile, fight both for social justice and to make America great again, two seemingly noble ideas, both exercises in futility. The wheel is still turning and the change of season soon upon us. What will you do?

    Whale Deaths

    “PORTLAND, Ore. – So many gray whales are dying off the U.S. West Coast that scientists and volunteers dealing with the putrid carcasses have an urgent request for coastal residents: Lend us your private beaches so these ocean giants can rot in peace.
     
    The number of dead whales washing ashore in Washington state alone – 29 as of this week – means almost every isolated public beach has been used. Authorities are now scrambling to find remote stretches of sand that are privately owned, with proprietors who don’t mind hosting a rotting creature that’s bigger than a school bus and has a stench to match its size.
     
    “The preferred option is, at all times, that they just be allowed to decompose naturally,” said John Calambokidis, a research biologist with the Olympia, Washington-based Cascadia Research. “But it gets harder and harder to find locations where they can rot without creating a problem. This is a new wrinkle.”
     
    At least 81 gray whale corpses have washed ashore in California, Oregon, Washington and Alaska since Jan. 1. If tallies from Mexico and Canada are added, the number of stranded gray whales reaches about 160 and counting, said Michael Milstein, spokesman for NOAA Fisheries.”

    Oh that it should come to this...

    I read the Jesper Andersson piece at Medium and wanted to comment. Unfortunately, Medium requires that a commenter either subscribe to Google or Facebook. I don’t subscribe to either. Medium may be unintentionally eliminating comments as a result. Since it appears that Jesper A may be a PP member, I’ll post my comment here. Jesper, are you familiar with Process Theology/Philosophy? Based on what I’ve read, Process theologians and philosophers have spent a great deal of time — since Alfred North Whitehead — thinking and writing about the topics that you address.
