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.

Rebuilding a Solar Powered Website

You’re looking at a completely rebuilt version of the solar powered website, which now allows you to turn off the dithering compression and see the original images.

Low-tech Magazine: The Comic

Filmmaker Guillaume Lion visited Low-tech Magazine in Barcelona and turned his experience into a comic for the Belgian magazine Médor.

What if We Replace Guns and Bullets with Bows and Arrows?

The bicycle and the bow are both highly efficient, human-powered technologies that could substitute for two very harmful alternatives: the car and the firearm. Why do we promote one but not the other?

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 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.

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.

Mist Showers: Sustainable Decadence?

The water and energy use of the mist shower is so low that the bathroom could be taken off-grid and off-pipe even in an urban context.
