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.

Too Much Combustion, Too Little Fire

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.

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.

Reinventing the Small Wind Turbine

A wooden rotor and tower greatly increase the net energy output over the lifetime of a small wind turbine.

Heat your House with a Mechanical Windmill

Given the right conditions, a mechanical windmill with an oversized brake system is a cheap, effective, and sustainable heating system.

Keeping Some of the Lights On: Redefining Energy Security

To improve energy security, we need to make infrastructures less reliable.

How to Build a Low-tech Website?

Our new website is designed to radically reduce the energy use associated with accessing our content.

Ditch the Batteries: Off-Grid Compressed Air Energy Storage

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.
