Our self-hosted, solar-powered, off-grid website has been running for 15 months now. In this article, we present its energy and uptime data, and calculate the embodied energy of our configuration. Based on these results, we consider the optimal balance between sustainability and server uptime, and outline possible improvements.

During the last months we have been working on transforming Low-tech Magazine into a multilingual publication. Many articles had been translated over the years, but they were not easy to find. Now, each language has its own solar powered main page.
The French and Spanish versions are the most complete for now, with respectively 73 and 47 articles online. Dutch, German, Polish, Italian, and Portuguese main pages are also available. Some languages also have articles that are not translated into English.

The fire – which we have used in our homes for over 400,000 years – remains the most versatile and sustainable household technology that humanity has ever known. The fire alone provided what we now get through a combination of modern appliances such as the oven and cooking hob, heating system, lights, refrigerator, freezer, hot water boiler, tumble dryer, and television. Unlike these newer technologies, the fire had no need for a central infrastructure to make it work, and it could be built locally from readily available materials.
The printed version of Low-tech Magazine can be viewed with no access to a computer or a power supply -- or when the solar powered website is down due to bad weather.
The second volume of the printed website is out now and contains 32 articles originally published between 2007 and 2012. The book, which has 618 pages and 268 images, is for sale in the Lulu Bookstore.
Whereas the first volume contained all but a handful of web articles published between 2012 and 2018, this second volume features a third of the web articles published in the earlier years, carefully selected for their continued relevance and interest today. Overall, we wanted to make an attractive book with timeless articles rather than an exact copy of the website.

The daily shower would be hard to sustain in a world without fossil fuels. The mist shower, a satisfying but forgotten technology which uses very little water and energy, could be a solution. Designer Jonas Görgen developed a do-it-yourself kit to convert almost any shower into a mist shower and sent me one to try out.
For more than two thousand years, windmills were built from recyclable or reusable materials: wood, stone, brick, canvas, metal. When – electricity producing – wind turbines appeared in the 1880s, the materials didn’t change.
It’s only since the arrival of plastic composite blades in the 1980s that wind power has become the source of a toxic waste product that ends up in landfills.
New wood production technology and design makes it possible to build larger wind turbines almost entirely out of wood again – not just the blades, but also the rest of the structure. This would solve the waste issue and make the manufacturing of wind turbines largely independent of fossil fuels and mined materials. A forest planted in between the wind turbines could provide the wood for the next generation of wind turbines.
