The Future is Degrowth

Quoted from: Schmelzer, Matthias, Andrea Vetter, and Aaron Vansintjan. The Future is Degrowth: A Guide to a World Beyond Capitalism. Verso Books, 2022.

These days, with growing interest in degrowth, it seems that almost every other week another humourless columnist for a major newspaper writes a criticism of degrowth. This is to be expected and even, to a certain extent, welcomed: the more those in positions of power rail against degrowth, the more people who might be sympathetic to it, who would otherwise not have heard about it, are exposed to it.

And, indeed, it also fulfils degrowth’s initial goal as a provocation, a conversation starter, a shit-disturber. Yet, usually, these columnists show little understanding of what degrowth means – and so their objections tend to badly miss the mark. [Read more…]

Does the circular economy fuel the throwaway society?

Quoted from: Figge, Frank, et al. “Does the circular economy fuel the throwaway society? The role of opportunity costs for products that lose value over time.” Journal of Cleaner Production (2022): 133207. Image: Horse Power by Stuart Taylor. Credit: JulieMay54 – CC BY-SA 4.0.

Extending the lifetime of products and using resources circularly are two popular strategies to increase the efficiency of resource use. Both strategies are usually assumed to contribute to the eco-efficiency of resource use independently… We find that in a perfectly circular economy, consumers are incentivized to discard their products more quickly than in a perfectly linear economy. A direct consequence of our finding is that extending product use is in direct conflict with closing resource loops in the circular economy… The article highlights the risk that closing resource loops and moving to a more circular economy incentivizes more unsustainable behavior.

Trail Marker Trees

Trail Marker Trees were an ancient form of land and water navigational aids, as well as a marking system to denote areas of significant importance such as ceremonial sites. These trees were used by many, if not all, of the Native American tribes and later by fur traders and early pioneers. The Trail Marker Trees differed in their appearance and formation from tribe to tribe and from region to region. Examples of these trees have been found all across the United States and throughout Canada.

One unique characteristic of the trail marker tree is a horizontal bend several feet off the ground, which makes it visible at greater distances, even in snow. Researcher Dennis Downes was first introduced to the Trail Marker Trees as a young boy and was influenced by his own Native American relative. Mr. Downes has spent nearly thirty years of his adult life in the field locating, documenting, and educating others about these historical icons. See and read more on his website: Great Lakes Trail Marker Tree Society. There’s also a Wikipedia page on the topic.

State of the Art of Windthermal Turbines

As Low-tech Magazine wrote in 2019, given the right conditions, a mechanical windmill with an oversized brake system is a cheap, effective, and sustainable heating system. Earlier this year, Malte Neumeier from the German Aerospace Center informed us that he and his team are investigating the technical and economical challenges of the technology.

“We started our research, with a birds eye techno-economic analysis and a scoping review. The results were promising, so we decided to build our own prototype. To refine our analysis, we are now searching for people, who already have experience with this technology. Maybe we could discuss some lessons learned. Do you have contact to any person experienced in wind-thermal energy applications? I would really appreciate this.” [Read more…]
