If burning metal powder as fuel sounds strange, the next part of the process will be even more surprising. That rust can be regenerated straight back into iron powder with the application of electricity, and if you do this using solar, wind or other zero-carbon power generation systems, you end up with a totally carbon-free cycle. The iron acts as a kind of clean battery for combustion processes, charging up via one of a number of means including electrolysis, and discharging in flames and heat.From Dutch brewery burns iron as a clean, recyclable fuel
An excellent, short post from Jason Crawford containing things that everyone who lives in a modern industrial society should know.
That plastics are produced in enormous quantities because, for so many purposes—from food containers to electrical wire coatings to children’s toys—we need a material that is cheap, light, flexible, waterproof, and insulating, and that can easily be made in any shape and color (including transparent!) That before plastic, many of these applications used animal parts, such as ivory tusks, tortoise shells, or whale bone. That in such a world, those products were a luxury for a wealthy elite, instead of a commodity for the masses, and the animals that provided them were hunted to near extinction.
The great Camille Fournier has another blog post that is worth reading:
The managers who succeed in this may have big ideas about the technology, the product, and the talent and culture of the team, but they don’t just start with these ideas. Instead, they identify the little things that can be changed. Questions like “how do we decide what we’re working on today” and “do we have clear responsibilities for core tasks” start to get resolved. These managers may tackle confusing on-call schedules, or onerous project management expectations. The best will look across the projects and quickly re-prioritize work to gain focus for the team.From The Management Flywheel
