Wood stoves equipped with thermoelectric generators can produce electricity that is more sustainable, more reliable, and less costly than power from solar PV panels.
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.
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 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.
A wooden rotor and tower greatly increase the net energy output over the lifetime of a small wind turbine.
