How to Build a Solar Powered Electric Oven

This guide explains how to construct an energy-efficient cooking appliance powered by a small solar panel. Thanks to its heat storage, the cooker remains ready to use even after sunset.

How to Assemble an Electric Heating Element from Scratch

This manual guides you through the process of building a 12V DC electric resistance heating element for a self-made heating or cooking device.

The Compressed Book Edition

How to make books more sustainable? Inspired by the image compression on our solar-powered website, we squeezed the article catalog of our three-volume book series into just one book.

Communal Luxury: The Public Bathhouse

Throughout history, people have bathed in public rather than in private. Should we bring back the public bathhouse for the sake of sustainability?

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.

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.
