Low Tech Lives | Philippe Bihouix Aug 20, 2026 3077 The world is full of good ideas and solutions to the crisis. But good ideas cannot trump the laws of physics, and solutions will only be such if they are deployed in a manifestly different way than our current high-energy, high-material, high-consumption regime demands.  Philippe Bihouix is an engineer and the author of The Age of Low Tech (UK version, US version), which examines why technological

P:C ARCHIVES: Simon Michaux on The Climate Crisis and The Climate Crash Jul 2, 2026 4115 FROM THE ARCHIVES: So much of the hope we put in solutions for climate change falls away under a microscope.

How can we mitigate climate change, truly, wi
