Using solar panels without backup infrastructure makes renewable energy production much more affordable, efficient and sustainable.
Andy Lagzdins built and documented a pedal-powered air compressor to run the power tools in his motorcycle workshop.
The printed archives of Low-tech Magazine now amount to four volumes with a total of 2,398 pages and 709 images.
Wood stoves equipped with thermoelectric generators can produce electricity that is more sustainable, more reliable, and less costly than power from solar PV panels.
We present our website’s energy and uptime data, calculate the embodied energy of our configuration, consider the optimal balance between sustainability and server uptime, and outline possible improvements.
Given the right conditions, a mechanical windmill with an oversized brake system is a cheap, effective, and sustainable heating system.
To improve energy security, we need to make infrastructures less reliable.
Our new website is designed to radically reduce the energy use associated with accessing our content.
Compressed air energy storage is a sustainable and resilient alternative to chemical batteries, with much longer life expectancy, lower life cycle costs, technical simplicity, and low maintenance.
Historical compressed air systems hold the key to the design of a low-tech, low-cost, robust, sustainable and relatively energy efficient energy storage medium.
Adjusting energy demand to supply would make switching to renewable energy much more realistic than it is today.
Matching supply to demand at all times makes renewable power production a complex, slow, expensive and unsustainable undertaking.
