The Anatomy of Artificial Intelligence

 
In 1770, Hungarian inventor Wolfgang von Kempelen constructed a chess-playing machine known as the Mechanical Turk. His goal, in part, was to impress Empress Maria Theresa of Austria. This device was capable of playing chess against a human opponent and had spectacular success winning most of the games played during its demonstrations around Europe and […]

How to Build a Low-tech Website?

 últim editat: Wed, 26 Sep 2018 04:27:58 +0300  
Low-tech Magazine was born in 2007 and has seen minimal changes ever since. Because a website redesign was long overdue — and because we try to practice what we preach — we decided to build a low-tech, self-hosted, and solar-powered version of Low-tech Magazine. The new blog is designed to radically reduce the energy use associated with accessing our content. First prototype of the solar powered server that runs the new website. Read this article on the solar powered website. Why a Low-tech Website? We were told that the Internet would “dematerialise” society and decrease energy use. Contrary to this projection, it has become a large and rapidly growing consumer of energy itself. According to the latest estimates, the entire...

Taking back the wheel. In the future heralded by Silicon Valley, cars will fly and labor will be disposable. But none of this is inevitable. It’s a political choice—that we can still reject. Engineering the climate could cost us the Earth. A political technology, geoengineering belongs to the institutional apparatus that is preventing effective climate […]

Could We Dredge the Netherlands Without Fossil Fuels?

 últim editat: Wed, 17 Oct 2018 03:02:09 +0300  
The dredging industry has been the backbone of the Dutch economy for centuries. If canals, harbours and rivers would not be maintained for a few years, the whole country would literally grind to a halt. Today, dredging happens with oil powered ships, which burn up to 3,000 litres of fuel per hour. However, in earlier times, the Dutch waterways were dredged mostly by hand, using simple but ingenious tools. Manual dredging was heavy labour, especially when waterways became deeper. Therefore, it was supplemented by animal power, wind power and tidal power. However, in some parts of the Netherlands, people chose a different strategy: they designed a new type of cargo ship that could sail in shallow waterways. 1699 scale model...

Fermentation and Daily Life

 
There is a moment in the life of fruits and vegetables that has always puzzled and fascinated me. Put out a dish of strawberries, and in days some darker spots will appear. Maybe a thin tendril of mold sprouts out from the strawberry’s body. At this point, you can still eat it, simply by cutting […]

Historical Storage Cellars in Budapest

 
The Kőbánya district of Budapest is situated on the eastern margins of the Hungarian capital city. Beneath Kőbánya there is an extensive limestone layer, in which tunnels and passages have been made, some of which appear to date from the 13th century. In the 19th century, the limestone caverns of the Hungarian capital city Budapest […]

We Can't Do It Ourselves

 
We have trouble sending out e-mails to subscribers. Our apologies if this mail was sent twice. How to live a more sustainable life? This question generates a lot of debate that is focused on what individuals can do in order to address problems like climate change. For example, people are encouraged to shop locally, to buy organic food, to install home insulation, or to cycle more often. But how effective is individual action when it is systemic social change that is needed? Individuals do make choices, but these are facilitated and constrained by the society in which they live. Therefore, it may be more useful to question the system that requires many of us to travel and consume energy as...

Ditch the Batteries: Off-Grid Compressed Air Energy Storage

 últim editat: Wed, 26 Sep 2018 04:12:13 +0300  
Read this article on our solar powered website -- if it is available. Going off-grid? Think twice before you invest in a battery system. Compressed air energy storage is the sustainable and resilient alternative to batteries, with much longer life expectancy, lower life cycle costs, technical simplicity, and low maintenance. Designing a compressed air energy storage system that combines high efficiency with small storage size is not self-explanatory, but a growing number of researchers show that it can be done. Compressed Air Energy Storage (CAES) is usually regarded as a form of large-scale energy storage, comparable to a pumped hydropower plant. Such a CAES plant compresses air and stores it in an underground cavern, recovering the energy by expanding (or...

History and Future of the Compressed Air Economy

 últim editat: Wed, 16 May 2018 00:40:42 +0300  
Compressed air energy storage (CAES) is considered to be an important component of a renewable power grid, because it could store surplus power from wind turbines and solar panels on a large scale. However, in its present form, the technology suffers from large energy losses and depends on natural gas to operate. A look at the 4,000 year long history of compressed air makes clear that this is not unavoidable. Although our ancestors were dependent on less energy efficient technology, they used compressed air in more intelligent configurations that had fewer energy conversion losses and were independent of fossil fuels. These historical systems hold the key to the design of a low-tech, low-cost, robust, sustainable and relatively energy efficient energy...

New CNI channel & call for curators!
We are also looking for people who want to help finding good sources of high quality inspirations and put some time into re-publishing content with meaningful comments. Such contribution would be highly appreciated and help us take the "CNI Coop Social center" off the ground.

The goal is to create information channels  covering the topics under broad definition of "Liberatory technology" — technology cultivated and implemented to empower self-organised communities.

We can define them as we wish. We have our own server, with installed Hubzilla (federated social network software) and full administrative control. The crucial thing is to get people on board, who'd take care of selectng quality (real, meaningful and practically oriented) content, put some intelligent introduction, hashtags and publish.

We want to make it a popular source among federated networks and bring more people both to the topic of technology as a tool for grassroot political change and to support CNI efforts in this area.

Talk to us, if you are interested. Share anyway.

New CNI channel!
So, we start a new information channel. "Low & Appropriate Trusted TEchnology" aka L.A.T.TE feed.
It has three goals:
— to create a place where hand-picked and curated low-tech solutions will be presented, commented and discussed, outside of corporate media cage;
— to bring more people to our #Hubzilla instance and eventually get them involved in our projects;
— to increase visibility of our (micro)donation system, soon to be implemented online.
You can see the channel here: https://cni-coop.net/channel/cni-latte-feed, subscribe to RSS here: https://cni-coop.net/feed/cni-latte-feed or reach out across federated social media to add us: cni-latte-feed@cni-coop.net

Metabolizer your trash!

  
This guy is really good. Sam Smith is in the middle of creating a bio-mimicking technological metabolizer -- a system to convert typical American household stream of waste into some useful resources (including fuel for metabolizer itself). He got into semi-finals of Hackaday's Open Hardware Challenge and has good chance for the main prize. Look at it!

Pains and perils of using the renewable energy in a wrong way.

  últim editat: Sun, 06 May 2018 19:07:53 +0300  
The most important part of introducing renewable energy at large is to change the structure and timing of energy consumption. This article shows well documented cases of serious problems, whenever we try to make renewable energy ever-available, without paying attention to it inherent seasonal and daily fluctuations. The text makes it clear that the proper approach is to follow natural tides of energy in the system.

How (Not) to Run a Modern Society on Solar and Wind Power Alone
While the potential of wind and solar energy is more than sufficient to supply the electricity demand of industrial societies, these resources are only available intermittently. To ensure that supply always meets demand, a renewable power grid needs an oversized power generation and transmission capacity of up to ten times the peak demand. It also requires a balancing capacity of fossil fuel power plants, or its equivalent in energy storage. Consequently, matching supply to demand at all times makes renewable power production a complex, slow, expensive and unsustainable undertaking. Yet, if we would adjust energy demand to the variable supply of solar and wind energy, a renewable power grid could be much more advantageous. Using wind and solar energy only...
