Power Water Networks

During the second half of the nineteenth century, water motors were widely used in Europe and America. These small water turbines were connected to the tap and could power any machine that is now driven by electricity.

Fruit Walls: Urban Farming in the 1600s

From the sixteenth to the twentieth century, urban farmers grew Mediterranean fruits and vegetables as far north as England and the Netherlands, using only renewable energy.

Reinventing the Greenhouse

Contrary to its fully glazed counterpart, a passive solar greenhouse is designed to retain as much warmth as possible.

How to Build a Low-tech Internet

While the high-tech approach pushes the costs and energy use of the internet higher and higher, the low-tech alternatives result in much cheaper and very energy efficient networks that combine well with renewable power production and are resistant to disruptions.  

Why We Need a Speed Limit for the Internet

We need a speed limit for the internet.  

How Sustainable is Stored Sunlight?

Driven by better battery technology and the disincentivization of grid-connected solar panels, off-grid solar is about to make a comeback. How sustainable is a solar PV system if energy storage is taken into account?

How Sustainable is PV Solar Power?

Solar photovoltaic (PV) systems generate "free" electricity from sunlight, but manufacturing them is an energy-intensive process.

Heating People Not Places: How to Keep Warm in a Cool House

If we rely solely on insulation, solar energy and sustainable architecture, it would take too much time to address the high energy use of buildings.

Heating People Not Places: Radiant & Conductive Heating Systems

Restoring the old way of warming would not make sense without new technology.

Restoring the Old Way of Warming: Heating People, not Place

It would make a lot of sense to restore this old way of warming, especially since modern technology has made it so much more practical, safe and efficient.
