The Office on the Move: Portable & Pocket Typewriters

hermes-featherweightAt least since the 1980s, home working has been touted as a trend with potential environmental benefits. Since the arrival of mobile phones, portable computers and the internet in the 1990s, the focus has shifted to “remote” or “agile” working, which includes working at home but also on the road and in so-called third places: coffeeshops, libraries or co-working offices.

According to a 2014 consultancy report, “the vast majority of jobs in most organisations can be accomplished from virtually any PC or mobile device, from just about anywhere”. Upon a closer look, however, wireless computing isn’t that revolutionary as you would expect. The laptop and the internet have eroded the anchoring function of the office, but this is only a novelty if you compare with the office of 25 years ago. In a larger historical context, not that much has changed.

Human Powered 3D Printer


The Trophy is a 3D Print Machine, consisting of an Ultimaker 3D printer and a stationary bicycle to power it. Pierre-Clement Niviere designed it to make people aware of the high energy consumption of printing a 3D-object, criticising a technology that’s usually presented as an environmentally friendly way of production. The set-up also involves the maker in the creation process, raising questions about how 3D printing is changing making.

Vertical Walking

vertical-walking-stairs“Even as our cities get more crowded and its buildings get taller, it seems that we have yet to find a more energy efficient way to navigate this high-rise environment. Right now, our options are limited to stairs, escalators, and elevators—all of which are expensive, require constant maintenance, and take up a lot of space.

Enter Rombout Labs and their concept of “vertical walking.” Their technology is designed to allow humans to move between building floors without the need for any sort of power supply, also using less effort than we would if we were using stairs, and making optimal use of available vertical space.

“By using harmonious movements and smart materials, only 10% of the effort of walking stairs is needed to bridge multiple floors. This not only provides a solution for the growing number of people who are unable to take stairs, but moreover offers new possibilities for urban architecture,” they explain on the Dutch Design Week website, where the system is currently featured.”

Pigeon Towers: A Low-tech Alternative to Synthetic Fertilizers

Many societies, ancient and contemporary, have innovated ways of supplying their fields with fixed nitrogen and phosphorus—two crucial ingredients for crop productivity. One is crop rotation, which alternates nitrogen-fixing and nitrogen-exhausting crops. Farmers around the world make use of chickens, ducks, and geese to add “fresh” guano to their fields. Cattle manure is another useful alternative—although it often lacks in phosphorus. Much more labor intensive than simply adding fossil-fuel derived synthetic fertilizer, these practices tend to build up soil, limit greenhouse gas emissions, and lead to less run-off into rivers, lakes, and oceans.

Persian pigeon towers are one of the more elegant solutions to the nitrogen-phosphorus problem. These are essentially castles built for thousands of wild pigeons, strategically placed in the middle of the fields. Their droppings were shoveled up once a year and sold to nearby farmers. While most pigeon towers existing today are in disrepair, the oldest still standing are dated to the 16th century (but they are assumed to have existed over 1,000 years ago) and helped fuel the cultivation of Persia’s legendary orchards, melons, and wheat production.[1] [Read more…]

Smart lamps can use more energy than incandescent lights


“Combining wireless communication, intelligent controls and light emitting diodes (LEDs), smart lamps offer end-users features like colour tuning, dimming, changing lighting scenes, remote control, motion sensing control, daylight control and other features. But these features require energy even when the lamps are not providing light, but are instead waiting for a wireless instruction from a smartphone or remote control unit. Tests conducted on a limited number of smart wireless LED lamps reveal that these products can have substantial standby power use – which, depending on hours of use, can even be higher than the energy consumed when the light is switched on.”

“Domestic light sources… typically operate 1-2 hours per day. The smart lamps producing 200 to 1000 lumens of light tested in this project had an average standby energy consumption representing 51 % of the total daily energy consumption when these lamps are operated one hour per day. That corresponds to an overall efficacy of 9 to 51 lumens per watt, meaning some smart lamps had the equivalent performance of incandescent lamps [16 lumens per watt]. If the lamps are switched on for two hours per day, standby energy represented 35 % and the efficacy is approximately 16 to 64 lumens per watt, much lower than the non-smart LED lamps already on the market today.”

Communal Bathing

communal bathing

“For most of the history of our species, in most parts of the world, bathing has been a collective act… But communal bathing is rare in the modern world. While there are places where it remains an important part of social life – in Japan, Sweden and Turkey, for example – for those living in major cities, particularly in the Anglosphere, the practice is virtually extinct. The vast majority of people in London, New York and Sydney have become used to washing alone, at home, in plexi-glass containers – showering as a functional action, to clean one’s own private body in the fastest and most efficient way possible.”

“The bathhouses of the future, by reinventing the historical social functions of their ancient originals and combining their most attractive aspects to build a new model, would compensate for the erosion of public spaces elsewhere… Politically, too, they could be part of a wider effort to construct sustainable economic models. Last year at the UN climate change conference in Paris, countries agreed to phase out gas boilers and replace them with carbon-friendly alternatives. Although boilers do not pollute to the same degree as cars, aeroplanes or cattle farms, our individual commitments to private washing is part of an unsustainable burden on the planet. Solar-powered public baths could lighten the load.”

Rethink, Retool, Reboot: Technology Justice

rethink retool rebootPractical Action, the international NGO that uses technology to challenge poverty in “developing” countries, has published a new book that is freely accessible online. Rethink, Retool, Reboot: Technology as if People and Planet Mattered is written by Simon Trace.

A fifth of the world’s population lacks access to technologies fundamental to a basic standard of living, while unfettered use of technology by those who have it brings its own problems. Inspired by EF Schumacher’s 1973 book Small is Beautiful, Trace argues that ending poverty and achieving environmental sustainability cannot be realized without radical changes to the way technology is developed, accessed, and used:

“Humanity has lost control of technology, or rather relinquished it to the vagaries of the market, assuming its ‘invisible hand’ will ensure the most efficient development and dissemination of technology that best meets people’s needs – an assumption that is wrong.”

The book is divided into three sections. Part 1 starts by looking at notions of technological progress and the relationship between technology and human development, demonstrating the need to ‘rethink’ how we use and provide access to technology. Part 2 goes on to explore the idea that we need to ‘retool’ — to re-examine our innovation processes — in order to focus on driving technology development towards, rather than away from, the twin problems of poverty and environmental sustainability. The book closes with a third section that sets out a series of radical changes required to ‘reboot’ our relationship with technology.
