Power Transmission

How to Escape From the Iron Age?

We cannot lower carbon emissions if we keep producing steel with fossil fuels.

Keeping Some of the Lights On: Redefining Energy Security

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

History and Future of the Compressed Air Economy

Historical compressed air systems hold the key to the design of a low-tech, low-cost, robust, sustainable and relatively energy efficient energy storage medium.

How to Run the Economy on the Weather

Adjusting energy demand to supply would make switching to renewable energy much more realistic than it is today.

How (Not) to Run a Modern Society on Solar and Wind Power Alone

Matching supply to demand at all times makes renewable power production a complex, slow, expensive and unsustainable undertaking.

Slow Electricity: The Return of DC Power?

Directly coupling DC power sources with DC loads can result in a significantly cheaper and more sustainable solar system.

Power Water Networks

Hydraulic power transmission is very efficient compared to electricity when it is used to operate powerful but infrequently used machines.

Power from the Tap: Water Motors

In the nineteenth century, miniature water turbines were connected to the tap and could power any machine that is now driven by electricity

The Mechanical Transmission of Power (3): Endless Rope Drives

The trend towards small-scale, decentralised power production means that rope transmission might have a place in our energy system again

The Mechanical Transmission of Power (2): Jerker Line Systems

Jerker line systems can be used to operate water pumps or sawing machines, to forge iron, to process food or fibres, or to make paper.

The Mechanical Transmission of Power (1): Stangenkunst

Long-distance power transmission predates the invention of electricity by almost four centuries.
