Why heroes don’t change the world | David LaMotte | TEDxAsheville

oleh



Heroism is overrated. It is always movements that lead to large-scale change, though our dominant cultural narrative of change focuses on individuals. It is not naive to think you can change the world, it is naive to think you could be in the world and not change it, but that change happens in community.

David LaMotte is a songwriter, speaker and author. He has performed over 3500 concerts and released thirteen full-length CDs of primarily original music, as well as four books, touring in all of the fifty states and on five of the seven continents over his 35-year career. He holds a master’s degree in International Studies, Peace, and Conflict Resolution from the University of Queensland in Brisbane, Australia, which he attended as a Rotary Peace Fellow. He is the former Clerk of the AFSC Nobel Peace Prize Nominating Committee, and a co-founder of Senderos, Inc., which has been working to support education in Guatemala since 2004. He lives in Black Mountain, North Carolina, with his wife and son, an old dog, and five chickens. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at

  1. Great David!
    Long time since we met at Lyon College, Batesville, Arkansas (2002).
    I've been working with extra-ordinary people since (personnes en situation de handicap). "Worldchanging 101" has been on my shelf for years (and moved to Brittany a couple of year ago)
    I'll spread the video on the French network. I need to change some of the subtitles first 😉

  3. Technology may have advanced enough to release civilization from the confines of the second law of thermodynamics.

    The second law is behind modern refgeration needing electrical energy to compress the refrigerent to force it to release as waste the heat that it has removed from the refrigerator's service interior in the cooling part of the refrigerent's circulation. There is also discarded heat from mechanical friction.

    Refrigeration by the principle that energy is conserved should produce electricity instead of consuming it.

    It makes more sense that refrigerators should yield electricity because energy is widely known to change form with no ultimate path of energy gain or loss being found. Therefore any form of fully recyclable energy can be cycled endlessly in any quantity.

    In an extreme case senario full heat recycling all electric very isolated underground communities would be highly survivable with self sufficient EMP resistant LED light banks, automated vertical farms, thaw resistant frozen food storehouses, factories, dwellings, and self contained elevators and horizontal transports.

    In a flourishing civillization senario small self sufficient electric or cooling devices of many kinds and styles like lamps smartphones, hotplates, water heaters, cooler chests, fans, radios, TVs, cameras, security devices. power hand tools, pumps, and personal transports, would be available for immediate use anywhere as people see fit.

    Larger equipment would be built for enterprise use.

    If a high majority thinks our civilization should geoengineer gigatons or
    teratons of carbon dioxide out of our etnvironment, instalations using devices that convert ambient heat into electricity can hypothetically be scaled up do it with a choice of comsequences including many beneficial ones.

    Computers that consume electricity and yield heat would complement energy sensible refrigerators that absorb heat and yield electricity.  Computing would be free.

    A simple rectifier crystal can, iust short of a replicatable long term demonstration of a powerful prototype, almost certainly filter the random thermal motion of electrons or discrete positiive charged voids called holes so the electric current flowing in one direction predominates. At low system voltage a filtrate of one polarity predominates only a little but there is always usable electrical power derived from the source, which is Johnson Nyquest thermal electrical noise. This net electrical filtrate can be aggregated in a group of separate diodes in consistent alignment parallel creating widely scalable electrical power. The maximum energy is converted from ambient heat to productive electricity when the electrical load is matched to the array impeadence.

    Matched impeadence output (watts) is k (Boltzman's constant ~1.38^-23), times T  (tempeature Kelvin) times bandwidth (0 Hz to a natural limit ~2 THz @ 290 K) times rectification halving and nanowatt power level rectification efficiency times the number of diodes in the array.

    For reference, there are a billion cells of 1000 square nanometer area each per square millimeter, 100 billion per square centimeter.

    Order is imposed on the random thermal motion of electrons by the structual orderlyness of a diode array made of diodes made within a slab:

    v v v v v v v v v v v v v v v v v

    All the P type semiconductor anodes abut a metal conductive plane deposited on the top face of the slab with nonrectifying joins; all the N type semiconductor cathodes abut the bottom face. As the polarity filtered electrical energy is exported, the amount of thermal energy in the group of diodes decreases. This group cooling will draw heat in from the surrounding ambient heat at a rate depending on the filtering rate and thermal resistance between the group and ambient gas, liquid, or solid warmer than absolute zero. There is a lot of ambient heat on our planet, more in equatorial dry desert summer days and less in polar desert winter nights.

    Focusing on explaining the electronic behavior of one composition of simple diode, a near flawless crystal of silicon is modified by implanting a small amount of phosphorus (N type)on one side from a ohmic contact end to a junction where the additive is suddenly and completely changed to boron (P type) with minimal disturbance of the crystal lattice. The crystal then continues to another ohmic contact.

    A region of high electrical resistance forms at the junction in this type of diode when the phosphorous near the ĵunction donates electrons that are free to move elsewhere while leaving phosphorus ions held in the crystal while the boron ions donate holes which are similalarly free to move. The two types of mobile charges mutually clear each other away near the junction leaving little electrical conductivity. An equlibrium width of this region is settled between the phosphorus, boron, electrons, and holes. Thermal noise is beyond steady state equlibrium. Thermal noise transients, where mobile electrons move from the phosphorus added side to the boron added side ride transient extra conductivity so the forward moving  electrons are preferentally filtered into the external circuit. Electrons are units of electric current. They lose their thermal energy of motion and gain electromotive force, another name for voltage, as they transition between the junction and the array electrical tap. Inside the diode, heat is absorbed: outside the diode, an attached electrical circuit is energized.

    Understanding diodes is one way to become convinced that Johnson Nyquest thermal electrical noise can be rectified and aggregated. Development teams will find other ways to accomplish this wide mission. Taxonomically there should be many ways ways to convert heat directly into electricity.

    A practical device may use an array of Au needles in a SiO2 matrix abutting N type GaAs. These were made in the 1970s when registration technology was poor so it was easier to fabricate arrays and select one diode than just make one diode.

    There are other plausible breeches of the second law of thermodynamics. Hopefully a lot of people will join in expanding the breech. Please share the successes or setbacks of your efforts.

    These devices would probably become segmented commodities sold with minimal margin over supply cost. They would be manufactured by advanced automation that does not need financial incentive. Applicable best practices would be adopted. Business details would be open public knowledge. Associated people should move as negotiated and freely and honestly talk. Commerce would be a planetary scale unified conglomerate of diverse local cooperatives. There is no need of wealth extracting top commanders. We do not need often token philanthropy from the top if the wide majority of people can afford to be generous.

  5. Great talk sir. Powerful message. It is interesting that these hero narratives can actually have a negative effect by making us feel overcoming problems are insurmountable and futile. We're in this together comrades. ✊

  15. "They had done the boring mundane meetings to make this possible…" I don't know why but that brought me to tears. A good reminder that what sometimes feels like the boring mundane work we do matters too

  20. David, listened again to your 2017 TED talk and this, today. You speak your heart in both beautifully. Love the historical perspective in this one but I also identify with your use of musical metaphor in the other. I know this, that though you don't think of yourself as a "hero" you are, without a doubt, an inspirer, a mover. I want to thank you for your work and for the contagious passion to look more closely at what we can do. Donna from SPJ

  25. Hope to join the conversation this evening, to watch this again and reflect with others but my recent Covid bout is sapping energy a bit. The talk is so well done…movements, committees, people, list, reflect, rinse, repeat…

  26. I loved the book and the talk and David's sense of humor about serious stuff. As a lifer movement person, glad to get a booster shot for the work. I hope everyone who watches this will be inspired to join a movement to change the world.

  35. What changes will YOU make! It's an individual choice to gather groups of like-minded people to lead others to the same goal! What change are you leading? 🤔 The choices are endless. The need is endless. Thank you for making a change! Love that YOU are doing something good 👍🏻 ✨️ 💕 👏🏻 yay! I thank you from my heart 🌬💖🫂✨️🙌🏻✨️

  36. I think its really powerful to understand that all people understand the big problems in the world – what we squabble over and have political turmoil over is simply a matter of prioritization!

  37. False dichotomy; neither the lone hero nor the collective movement change anything; their actions are symbolic at worst; minorities – despised at best – do. Coteries, cabbals, salons, elites, cadres, squads, attic clubs, conspiracies, etc.

  40. David LaMotte encourages us to think of what happens in a totally new and exciting way—one we already practice in so many other everyday ways. We can understand from experience the "magic" of working together for a long time to produce the change that we know we need. Think about church and school and county and state committees. Realize that gathering together, working together and showing up together can create lasting and constant change, that believing and working together creates the hero "magic". We can all be "heroes" together to remove fear around not being able to solve our large problems.
