  • Steel decays via rusting as its outer coating is sacrificed to corrosion. Civil features decay as erosion degrades it over time. Wooden power poles decay as their treatment degrades and fungi/insects attack them. Outdoor wiring decays if in direct sunlight due to any sunlight resistive coating degrading over time to UV radiation. Oil used as lubricant in motor vehicles and as insulating fluid in electrical equipment degrades over time due to thermal cycling, oxidation, and moisture.

    The point I’m making is that things degrade naturally. Plastic is no exception, although engineers have been able to make certain decisions with it such that constructions can last for decades.

    If we can make plastic by default biodegrade naturally, and at a much faster time scale than today’s oxo-degradable and biodegradable alternatives, then it still allows for scientists and engineers to select for plastics that have been specifically engineered for the application via coatings and whatnot, comparable to steel and wood.

    It’s possible to do so. We just need to flip the script and make biodegradation the norm and not the exception


  • Plastics are also used extensively in the electricity sector as insulation for conductors, support structures, etc.

    We need our vendors of these products to start addressing this issue, and unfortunately I don’t think this is going to come from the consumer end. Maybe for alternative insulating liquids for transformers and whatnot like with Cargill FR3 or Shell MIDEL products, but clearly more needs to be done. Schneider Electric is a good example of a company leading the way







  • I’m sorry you went through that. It shapes us to have thicker skin, but it can also lead to bad outcomes depending on the friends and family involved.

    Ed Winters talked about this on his channel recently. One of the biggest reasons people don’t go vegan, and one of the biggest reasons pushing people away from the movement is the social dimension: living with people and still holding them as on your side when they very clearly violate your moral code. It’s one of the hardest burdens of vegans, as I’m sure it can be for other minorities. Again, I’m not equating vegans to a minority group like LGBTQ or POC. The animals are the minority group. But when you have discrimination and sometimes segregation for specific groups in society, you can start to draw parallels.

    Good luck with your vegan life from a fellow vegan 🤙






  • I guess it comes down to whether we want to primarily communicate battery size in terms of charge (Coulombs = Amps * Time) or energy (Joules = Watts * Time).

    The first metric you multiply by your operating voltage to get the second metric, whereas the second metric you have to divide by your voltage to get the first. Depends on what comes easier to most people.
