Low-tech Magazine 2018-2021

Low-tech Magazine underscores the potential of past and often forgotten technologies and how they can inform sustainable energy practices. Sometimes, past technologies can be copied without any changes. More often, interesting possibilities arise when older technology is combined with new knowledge and new materials, or when past concepts and traditional knowledge are applied to modern technology. Inspiration is also to be found in the so-called "developing" world, where resource constraints often lead to inventive, low-tech solutions. This third volume (368 pages, 183 images) contains 18 articles published between 2018 and 2021. Contents table: How Circular is the Circular Economy?
