How to Build a Small Solar Power System

This guide explains everything you need to know to build stand-alone photovoltaic systems that can power almost anything you want.

Test our Bike Generators in Paris, Rotterdam, and Barcelona

Low-tech Magazine built a bicycle generator for an exhibition on energy at the Pavillon d’Arsenal in Paris, now open to the public. Our two other bikes can be seen and experimented with in Rotterdam and Barcelona.

Direct Solar Power: Off-Grid Without Batteries

Using solar panels without backup infrastructure makes renewable energy production much more affordable, efficient and sustainable.

Human Powered Air Compressor and Energy Storage System

Andy Lagzdins built and documented a pedal-powered air compressor to run the power tools in his motorcycle workshop.

How to Build a Practical Household Bike Generator

We built a pedal-powered generator and controller, which is practical to use as an energy source and exercise machine in a household – and which you can integrate into a solar PV system. We provide detailed plans to build your own, using basic skills and common hand tools.

The Revenge of the Hot Water Bottle

Imagine a personal heating system that works indoors as well as outdoors, can be taken anywhere, requires little energy, and is independent of any infrastructure. It exists – and is hundreds of years old.

The Printed Website: Volume III & The Comments

The printed archives of Low-tech Magazine now amount to four volumes with a total of 2,398 pages and 709 images.

How to Build a Low-tech Solar Panel?

George Cove, a forgotten solar power pioneer, may have built a highly efficient photovoltaic panel 40 years before Bell Labs engineers invented silicon cells. If proven to work, his design could lead to less complex and more sustainable solar panels.

How to Design a Sailing Ship for the 21st Century?

It is surprisingly difficult to build a carbon neutral sailing ship. This is even more the case today, because our standards for safety, health, hygiene, comfort, and convenience have changed profoundly since the Age of Sail.

How to Make Biomass Energy Sustainable Again

From the Neolithic to the beginning of the twentieth century, coppiced woodlands, pollarded trees, and hedgerows provided people with a sustainable supply of energy, materials, and food.

Thermoelectric Stoves: Ditch the Solar Panels?

Wood stoves equipped with thermoelectric generators can produce electricity that is more sustainable, more reliable, and less costly than power from solar PV panels.

How Sustainable is a Solar Powered Website?

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.
