Approximately 5.7 million solid-walled houses exist in England, comprising 25% of the housing stock. Most were built between 1750 and 1914. Research shows that their energy efficiency has been underestimated for decades. [Read more…]

Mobile Clothes Washer

The Breathing Mobile Washer was designed so that manually plunging, the washer forces water through clothing. Compared to friction washing with hands, washboards and rocks, the mobile washer is easier to use, much less abrasive, reduces wear on clothes, and provides a superior clean. Review.

 

Slow Travel: Crossing Europe with a Giant Land Ship

Belgian art collective Time Circus built their first prototype of a giant Land Ship that will travel through Europe. Like a modern-day galley, the land ship will be propelled by the muscle power of the participating travelers. The journey is understood as a 21st century pilgrimage and will take an estimated 10 years. [Read more…]

Low tech? Wild tech!

The French scientific magazine Techniques et Culture has published an entire volume about alternative forms of technology: “Low-tech? Wild tech!“. The 300-page issue explores the differences and conflicts between high-tech and low-tech, with a focus on all the forms of technology which are in between these extremes.

The authors argue for a more sophisticated view of technological evolution, which is now usually seen as linear progress towards ever increasing complexity and perfection. The contributions show that reality is much more complicated, and much more interesting.

The issue is the fruit of a three-day discussion in Paris in 2012, in which I participated. The volume features a translated article from Low-tech Magazine: “How to build a low-tech Internet?”. “Low tech? Wild tech!” will be presented and discussed in Paris on December 9, 2017.

Prototype of a Hydro-Pneumatic Human Power Plant

The Human Power Plant is a working prototype of a muscular power generator, manned by a group of people. It is an all-round off-the-grid solution, which can supply energy in the form of electricity, water under pressure, and compressed air. It is built from simple and durable parts.

These days, we have automated and motorised even the smallest physical efforts. At the same time, we go to the gym to keep in shape, generating energy that’s wasted. The Human Power Plant restores the connection between physical exercise and energy use.

Non-Electric Hearing Aids Outperform Modern Devices

Most people with hearing problems are not using hearing aids, mainly because the electronic devices often do not provide enough benefit. Research shows that non-electric hearing aids from earlier centuries are performing significantly better.
