Forensic Oceanography is a research project started in 2011 by Lorenzo Pezzani and Charles Heller to investigate the militarised border regime in the Mediterranean Sea, and document the violence perpetrated against migrants attempting to cross the liquid border.

The sea, and in particular the Mediterranean, is a space of escape for thousands of people who leave the African continent in hope of a safer life in Europe. It is also a space of control and thus a political space. Much of what happens on the surface of that liquid political space takes place far away from the public gaze and often remains unaccounted for. However, the sea is closely surveilled, information about what happens and what sails through it is being generated, analyzed and recorded.

Forensic Oceanography looks at the sea as a witness to interrogate and cross-examine, re-purposing data and technologies initially produced as evidence of illegal migration and turning it into evidence of a crime of non assistance.

Lorenzo Pezzani was at The Lighthouse in Brighton a few weeks ago to talk about Forensic Oceanography and more particularly about the case of 72 migrants who had been left to die while they were attempting to flee Libya and reach the Italian shores during the Libyan conflict of 2011.

The Mediterranean is a fairly crowded sea and Western military forces were made aware of the refugees' distress shortly after the dinghy's departure when the captain lost control of the boat and called for help. The Italian coast guards received the appeal and relayed it, along with the position of the boat, to the NATO coordination centre and to military vessels present in the area. The distress calls were repeated every 4 hours for 10 days. But no-one came to their assistance. The dinghy was seen by an airplane, military helicopters, two fishing vessels and a large military vessel, which ignored their distress signals. After 15 days adrift, the boat washed up on the Libyan coast with only 11 survivors on board, two of whom died shortly afterwards. FO call the case, the 'left-to-die boat'.

Here's Liquid Traces, a short film which sums up the case.

And the video of Pezzani's presentation at The Lighthouse. It was a great evening. He talked about how a journey at sea is fast for goods and for privileged passengers but excruciatingly slow for the unwanted, about the dilemma of producing evidence to account for violence while trying not to be complicit with governments, about FO new project to make and distribute to migrants leaflets containing legal information about their rights, etc.

Mishka Henner has a solo show at the Carroll/Fletcher gallery right now. How come i never paid more attention to his work so far? Just like Edward Burtynsky, he looks at how industries shape landscapes. Like Trevor Paglen and Omer Fast, he is interested in (overt and covert) sites that the U.S. military deploys outside of its own borders. Just like Michael Wolf and Jon Rafman, he is a photographer using google mapping instruments instead of a camera. Yet, comparing his work to the one of some of the artists i admire the most is pointless. Henner is his own man slash artist. He uses contemporary technology to give a new twist on artistic appropriation and redefines the role of the photographer, the meaning of the photography medium and the representation of the landscape. Without ever using a photo camera.

The Black Diamond exhibition brings together four series of work, based on the collection and mediation of publicly available information sourced through the internet. Henner explains: 'I'm exploiting loopholes in the vast archives of data, imagery and information that are now accessible to us, connecting the dots to reveal things that surround us but which we rarely see or don't want to see.'

Oil Fields and Feedlots are large-scale inkjet prints taken from Google Earth's satellite imagery. The photos reveal landscapes carved by industries meeting the natural resource-devouring demands of two stalwarts of the U.S.'s hyper consumer society: oil and beef.

Feedlots are cattle-feeding operations used in factory farming to 'finish off' livestock. Almost all the beef consumed in the United States will have been finished on a feedlot where up to 100,000 steers at a time spend the last months of their lives gaining up to 4 pounds a day on a diet of corn, protein supplements, and antibiotics. Everything on these farms is calculated to maximise meat yield; from the mixture in cattle's feed to the size of run-off channels carrying the animal's waste into giant toxic lagoons.

In certain parts of the USA, natural features have long been supplanted by man-made marks and structures reflecting the complex infrastructural logic of oil exploration, extraction and distribution. The result is stunning. The prints look fake, painted over and heavily retouched. The exhibition essay compares the images to the work of abstract expressionists.

Naval Support Activity, Bahrain, 2010. 51 US Military Outposts

Diego Garcia, Indian Ocean, 2010. 51 US Military Outposts

Fifty-One US Military Outposts presents overt and covert military outposts used by the United States in 51 countries across the world. Once again, the sites were gathered and located using data which exists in the public domain, including official US military and veterans' websites, news articles, and both leaked and official government documents and reports.

"The internet is full of loopholes and leaks," the artist said. "I remember one day Hilary Clinton had categorically stated: 'we have no US military presence in Honduras.' However, the next day I was on Panoramio and was looking around pictures from Honduras - sure enough there was a photograph of a native Honduran worker with his arm around a sergeant major from the US cavalry regiment. The Honduran had even written to all his mates talking about how happy was to have got a job on this US military base. So the internet is full of these really simple leaks that completely contradict statements made by very powerful organisations."

The prints are displayed on plinths filling the rear gallery space, allowing visitors to walk around and watch the images from above, as if we were satellites. Or drones.




The walls of the space downstairs are covered with Henner's ongoing Scam Baiters series. Scam baiters are internet vigilantes who pose as a potential victims in order to waste scammer's time and potentially expose their identity,. They respond to their email, pretend to go along with the scammer's demands in exchange for time-consuming requests supposed to ensure that the money transaction will be successful. Henner is showing cardboard signs that various scammers were asked to make as a result of email conversations, negotiation of fraudulent documents and bogus websites. One case involved an almost four-month long correspondence between Henner's associate, 'Condo Rice' and a trio of scammers spread across Libya and the United Arab Emirates. In one of his final message, the scam baiter asks the scammer for proof of identity. He asks for a photo containing a U.S. flag held on a stick, a sign with SKAMMERZ ISHU, and 'to be absolutely certain this is a genuine photograph", the scammer has to wear an Obama mask.

Sound recordings of the scammers singing popular songs permeate the space.

Henner is currently shortlisted for Consumption, the Fifth Prix Pictet Award. The exhibition of finalists will be on display at the Victoria and Albert Museum, London in May 2014, where Henner will show a selection of works from his "Oil Fields" and "Feedlots" series.

Black Diamond is at Carroll/Fletcher in London until 31 May 2014.

Social Teletext Network

During the Arab Spring in Tunisia, Egypt, and Libya, governments restricted the access to the Internet in an effort to hamper online peer networking and thus self-organization. Could other governments ever operate a similar media shutdown and cut their citizens off the internet?

What would we do if ever an Internet kill switch was implemented in our country? Not necessarily to prevent us from orchestrating riots but to protect the internet "from unspecified assailants".

At the latest graduation show of the Design Interactions department in London, Philipp Ronnenberg was showing 3 methods to prepare for the time after a cyberwar. The Post Cyberwar Series proposes an alternative open navigation system, a makeshift wireless communication infrastructure as well as a novel data storage.

The Teletext Social Network enables people to bypass network providers and governmental institutions and communicate using the analogue television broadcasting which was freed last April in the UK.

OpenPositioningSystem relies on the seismic activity, produced by generators in power plants, turbines in pumping stations or other large machines running in factories to provide an open navigation system. I interviewed the designer about it a few months ago.

Finally, Sewer Cloud is a bit more complex. The system is inspired by the current research on the storage of data into DNA. 1 gram of DNA is capable of storing up to 700 terabytes of data.

People living in urban areas could use the Sewer Cloud as a living, self-reproducing data network. This living network would be located in the sewerage system and use the algae species Anabaena bacteria for the insertion and extraction of data.

Member using the Social Teletext Network

I contacted Philipp again to ask for more details about his project:

Hi Philipp! When i first interviewed you about the OPS, you didn't mention the kill switch. How did it go from one project about positioning system to a more complex scenario in which internet has been killed off? Were you inspired by any particular events from the recent news? I'm thinking of the NSA data collection: isn't controlling the internet and surveilling our every click enough for States?

The kill switch scenario stands for "killing" the Internet. But the Internet is only one network which is under control of companies and governmental institutions. The kill switch particularly is about the Internet, but other networks such as GPS navigation and mobile phone networks can be affected as well. In all three cases, the GPS navigation network, the mobile phone networks and the Internet, the control is in the hand of companies and governmental institutions.

I wanted to create three independent network alternatives. The body of work wrapped in the series Post Cyberwar is a reflection of how dependent we are today on the authoritarian structures of the networks we are using day to day. It is not only about surveillance and tracking down activity of users, it is also about content which becomes increasingly restricted, censored and monitored. The installation of controlling instances (i.e. kill switch) within these networks is justified with cyberwar and cyber-terrorism.
The recent news of the NSA data collection came just about right for the project. I have been working on the Post Cyberwar series since we last met. For me, it was always obvious that the NSA or any other governmental institutions are monitoring, but I was surprised about the dimension. Nowadays the perception (in the public) of surveillance has slightly changed, thanks to the main stream media and whistleblowers like Snowden. When I talked 5 years ago about surveillance and tracking, I often heard words like paranoid and being mistrustful.

Controlling the Internet and surveilling our every click is enough for getting an insight. But as we saw in Georgia, Egypt and sometimes China, shutting down the Internet and mobile phone networks (or at least parts of it), is a powerful way to prevent communication and the circulation of undesirable information.

OpenPositioningSystem. Sensor prototype


Speaking of OPS, how much has it grown since we last talked about it? Have the prototype and software improved and has the project given rise to attention and interest?

The OPS has grown a lot. First it got attention through your first blogpost and it was reblogged by some bigger blogs. I got very diverse feedback from "this comes out when art students try to be engineers (theverge.com comments)" and people asking me to get actively involved. I have 80 registered members on the website so far, but there is not much activity yet. I want to spend more time soon to bring new content on the website and therefore activate the registered members. The prototype and the software have slightly improved being more accurate and I worked on better tuning to seismic frequencies.

I gave two talks (#geomob London and W3C Open Data on the Web workshop) about the OPS so far where I tried to convince people to come on board. There is a third presentation at OHM2013 planned.
I applied for funding to bring the OPS to a working prototype stage in a small scale test area. I think, if I can build up a solid working prototype, the project will come to the next big step. There is still a lot of work to do.

Social Teletext Network

Is the Social Teletext Network installation at the show a working prototype? Which part of the communication would it replace exactly? I can't believe it could replace all internet communication, it seems to be so rudimentary.

The Social Teletext Network in the show was showing a demo. But I have the hardware and the software ready to switch it on. The demo in the show was created with the help of the same software which is used in the real setup. Unfortunately it is highly illegal to broadcast your own TV signals, therefore I decided to show a demo in the show. I could apply for analogue (VHF) frequencies, but it is very expensive (too expensive for a student project).

It is not meant to replace the entire Internet. The technical limitations for this task are too high. The Social Teletext Network is capable to provide wireless information streaming, using the old obsolete teletext technology, which makes it harder to track or to monitor. I tried to port some comfort which we know from computer interaction to the Social Teletext Network. For example: You can zoom into specific regions on a map and visualise user locations and other information.

The Teletext specifications provide a very limited resolution and it can only display text and graphics programmed with single pixels. Overall, the strength is that you can send and receive information wireless and over a distance (5km and even more possible with the right hardware and a high antenna).

Sewer Cloud. Stench pipes provide access points to the sewerage system

Sewer Cloud. Accessing the sewer system and obtaining algae

Sewer Cloud. Data extraction from and insertion into algae at the local corner shop

Algae circulation in London's sewer system

Could you explain me with more details the process of the data insertion and extraction from algae? Because if i want to retrieve some data, how do i know which algae i should fish and where?

Text, images, video and any piece of digital data is written in binary code (110011110). These 1's and 0's are then encoded to the four base-pairs of DNA (Adenine, Cytosine, Thymine and Guanine). The new base-pair string will be synthesised to a complete DNA string and inserted into living organisms. To read data out of a DNA string the base-pairs would be decoded to 1's and 0's again and from that to human readable information.
In the beginning of each DNA string, there is an address block which indicates what kind of information is in each string. With this method you could know what you will find in a specific piece of algae.

As 1 gram of DNA can hold up to 700 terabytes (700.000 gigabytes), the amount of data what you can find in a single piece is very high.

If you would insert data into algae and hide the algae at a specific site, the chance that it stays there is high. It would reproduce itself and the following generations would go on a journey. But if the conditions are good, the origin would stay at the same spot and you could still find the same data even years after you have put it somewhere. So the idea is more, that you would know by locations where you can find specific information.

Thanks Philipp!

La Cosa Radiactiva has brought a group of young engineers, musicians & artists on the roads of Spain to explore sites related with radioactivity.



The team (composed of Sergio Galán, Victor Díaz, Alejandro Pérez, Servando Barreiro, Marcos Carnero, Alvaro Santamaría and Javier Villaroel) is not always welcome in nor around the facilities they investigated but they nevertheless measured radioactivity in locations that range from the Arrocampo artificial lake (which water is used to refrigerate the turbines of the nearby Almaraz Nuclear Power Plant) to a dismantled uranium mine in La Haba (a small town of 1000 inhabitants in the Badajoz province), from the first nuclear power plant (in process of dismantling) in Zorita to a nuclear waste storage facility in El Cabril (Córdoba), etc.

They traveled with their own measurement and visualization system that combines a Geiger counter, an Arduino microcontroller and an app for Android phones. The data gathered is visualized on online maps and in the form of audiovisual performances organized on the public squares of the villages and small towns they visit. The findings collected are also used to trigger discussions with the local population as well as with a broader audience about the social and cultural impact of nuclear energy.

La Cosa Radiactiva is a "research on transparency and nuclear secrets. A performance to demystify radiation while building awareness of its risks. An imagination exercise to reflect on how it would be like to live with radiation and above all this, a call about the importance of citizens having their own tools to be able to verify public health data provided by governmental authorities."

La Cosa Radiactiva / The Radioactive Thing. English trailer

La Cosa Radiactiva / The Radioactive Thing is another brilliant project i discovered during my last visit to MediaLab Prado (i recently wrote about Citizen Cyber Science and the Freedom of Speech Kit.) Because i only had a few minutes to talk about it with Sergio Galán while i was in Madrid, i emailed him to ask him further questions about the project.

Hola Sergio! How much is known, made public in Spain about radioactivity? Was it easy for the team to find information about the location of radioactive sites?  

First of all, just to clarify, all places we visited were not radioactive, I mean, with high levels of radioactivity. They were places with some connection with the nuclear industries: mines, factories, centrals, storages... Some of them are still working some are dismantled.

So, answering the question, it is not a secret to find those places. These are mostly old industrial places which are documented in quite a few webs.
Then in Spain there is an official network of radiation sensors which is online.
Also incidences are reported and listed, so it is not bad.

But it is tricky. For instance, the ambient sensors provide a measurement of "radiation" around them, so we might think that if those sensors are below certain levels there is no risk.

There is a Geiger counter in many places where old mines or nuclear power plants are. Even if there were a leak or there is underground contamination, the geiger counter won't measure anything alarming unless something quite big is happening.

If you measure ambient radiation in a room where there is radioactively contaminated rice, you won't see a high measurement in your geiger counter, but it doesn't mean you can eat the rice. Counters detect external irradiation not contamination. If you don't know this, sensors can provide a fake "safe" feeling.

Furthermore when something happens, transparency falls down. In Spain during the last 30 years we haven't had a serious incidence, but even the small ones were hidden below the carpet. There was a tiny leak in ASCO - one of the nuclear power plants in Spain - and they didn't inform about the incidence until months later.

So it is a strange policy, always showing off transparency but hiding information when something happens. This is an example that should make us think twice before being too optimistic about the current transparency & open data wave - which of course I stand for - because it can also be used as a smoke curtain to hide things while seeming transparent.

One of the objectives of La Cosa Radiactiva is to 'hold workshops where people can learn about our work and about the radioactive phenomenon in a different way." How different is it from the way radioactivity is presented in mainstream media?  

Since it was discovered there has been a strong fascination for radioactivity, thinking about it as a kind of paranormal power like green waves emerging from minerals and mutating all life around. One of our goals when doing our workshops was to teach basic scientific knowledge. We explained that of course it might be dangerous but it is a natural phenomenon, governed by natural laws. And it is actually everywhere, it is on nature in low levels.

Reality is that a lot of people don't have a serious clue about what radioactivity is. I've talked to many people about the project I was doing and quite a few asked me if it had to do with mobile phone waves, which is a totally different issue. So people don't receive scientific education to differentiate electromagnetic waves from nuclear radiation, but we - as a democratic country or society - have decided that we can use it as one of our key energy sources

While on a tour to locate and measure radioactivity around Spain, you met with local communities. How aware (and maybe worried?) are they about the presence of radiation in their environment?  

We didn't make any serious poll, but my impression is that there is always a group of people interested and worried, but most of the people don't really care. For instance in a village were there used to be an uranium factory (where most of the workers died or are suffering uranium related illnesses) a guy told us that people don't talk about it. Some of them want to know if there is danger but at the same time they don't want to dig too much, because in case of finding something it might create economic troubles to the region.

So in the places we visited, when there is a nuclear power plant, people live well, they have jobs and so on. And they don't want to know. When there was something in the past, it is an old conflict. It is buried, only ecologists complain from time to time.

The exception is when there is an ongoing conflict. We visited a small village next to where the government plans to build a storage for nuclear waste and in that region people are really engaged, both for and against it.

What is the state of the nuclear energy discourse is in Spain right now? Is the country planing to create new power stations or is it looking for other forms of energy?

It is very ambiguous. On one hand there is a "nuclear moratory". Seven nuclear reactors were under construction in the 80's and then the government stopped them (so they are now just huge empty cement buildings that we are still paying, which is another interesting topic).

On the other hand, the active nuclear power plants, easily get new permissions to keep working for more years. Current government is more pro-nuclear than the old one, but I don't think they'll seriously plan to build more nuclear power plants, basically because they are very expensive, and require many years to start producing energy. Public sector is not investing on anything right now, and private sector won't invest unless they are strongly supported by public money/laws.

The official policy used to be to build more wind and sun powered plants -and Spain is actually among the leaders in both technologies. I think that it is the right thing, but is it enough? People like green energy and don't like carbon or nuclear, but nobody asks the uncomfortable questions like: Can we sustain our energy appetite with green tech only? Are we willing to pay more money for energy to avoid the energy sources with bad reputation? Or are we willing to stop our continuous growth system to consume less energy? 


Can you describe briefly the DiY Geiger counters you've made and how members of the public will one day be able to make their own? 

Since Fukushima's accident there has been quite a lot of interest for domestic Geiger counters, so they are becoming cheaper and smaller. The one we bought is made by a Spanish company and it is fully open hardware. It works over Arduino, and using the "Android-ready" version of Arduino we could connect it to the mobile phone.

So we don't build it but it is technically possible to build it from scratch. What we developed is a software to use the counter with Android phones. Thanks to the Medialab-Prado's open lab I contacted Alvaro and together with my colleague Victor we did all the Android+Arduino coding.

The goal was to build something more "user centered", a kind of nice interface for geiger counters so people can use it to make explorations and understand what's going on and how good or bad the measurement is.


Does the device show the difference between natural and man-made radioactivity? Sorry for the idiot question but have both forms of radioactivity the same impact on the environment?  

Please note that I'm talking as an amateur, not as a scientist, so I might be not very precise. But in essence there are three kinds of radioactive particles: Alpha Beta and Gamma. The three of them can be natural or man-made. A Geiger counter reads the total radiation level so we don't know if the radioactivity we are measuring is natural or not. However if you read an abnormally high level of radiation somewhere, there is probably some human involved there.

Each radioactive element decays into other element emitting different combinations of particles, so scientific equipment can find out if the radiation is coming from natural sources or from other elements which are not usual in nature or directly only exist in nuclear waste or in the nuclear fusion process.

Animals are used to live with low levels of natural radiation in their environment, so if it suddenly increases that is when health problems start to appear.

La Cosa Radiactiva is also about transforming nuclear radiation into image & sound. Can you explain us how?  

One of the main goals of the project was to work with radioactivity as a kind of input material for art or performances. So I contacted Servando Barreiro which is a media artist and VJ and also an old acquaintance. He had made a laser projector and with it he generates waves and shapes. For me, the aesthetic of his laser projections, resonates with what popular culture associates with radioactivity: green rays of death. So we agreed on working together. We added an option to the mobile app to stream the measurement levels. So Servando receives the measurement levels and he uses that information to change and modify the shapes of the projections.

My main idea was to have a kind of laser sculpture for villages with nuclear power plants. The laser sculpture will draw day after day the same bored calm shapes. But if there is a radiation leak and the village is in danger, the sculpture would mutate into creepy shapes, and people would admire it before realising that they are in danger.

It sounds poetic but we couldn't talk with the mayor of any place interested on having this. So I just tell it as a kind of design fiction, and in case a mayor of a "radioactive town" wants to build it, he can contact us.


Is the project over or are you planning to work further on it?  

I'd love to have some time to finish the app adding a nice visualisation on how dangerous the radiation level that you are measuring is. That will happen probably soon. But the project as it was imagined at the beginning is almost finished. Now I'm thinking on what to do with this. We could make a nice installation for art centres and so on, but we'll see. For now we've just released the documentary a couple of days ago. Marcos Carnero recorded our trip and together with Alejandro we made the script for a series of short films explaining the project and the opinions of the people we found.

For the future I'd like this to be a kind of public service. Like ghostbusters. People would send us an email telling: I think I saw green smoke coming out of the nuclear power plant yesterday. Can you explain us how the geiger counters works or can you come with your counters and tell us what's going on? But besides accidents, I think the main utility for geiger counters is educational. Showing people how it works, explaining that radioactivity is everywhere and using them as a tool to learn & talk (and get fascinated by Servando's figures if they have the chance to.)

Thanks Sergio!

The Art of Walking: A field guide. Edited by David Evans and published by Black Dog Publishing.

0atheartof aw.jpgAvailable on amazon USA and UK.

Book description: The Art of Walking: a field guide is the first extensive survey of walking in contemporary art. Combining short texts on the subject with a variety of artists work, The Art of Walking provides a new way of looking at this everyday subject.

The introduction relates peripatetic art now to a wide range of historic precedents, and is followed by a series of visually led 'Walks' dealing with seven overlapping themes: footprints and lines; writers and philosophers; marches and processions; aliens, dandies and drifters; slapstick; studios, museums and biennales; and dog walkers.

The guide includes newly commissioned art and writing, and many artists have been actively involved in the design of their respective pages.

This overview of artworks dealing with walking completely took me by surprise. I was expecting psychogeography, peripatetics, geolocation and theory. But The Art of Walking: A Field Guide is not only light on words, it also follows themes that range from aliens to slapstick to dog walking.

The way the content is illustrated is worth a mention too. There are the usual photos that document performances of course but also letters, preparatory drawings, souvenir programme, etc. The succession of images for each artwork allows the reader to fill in the dots, complete the short presentation text and create their own narrative. The author even asked some of the artists to participate in the editorial process. For example, The Art of Walking opens on a series of proposals that artist Peter Liversidge wrote down on his old typewriter for the author of the book, for himself or for the reader. He invites you to put down the book and go outside, for example. And following his suggestion, the book closes on 5 empty pages for you to write down notes.

The book was thus nothing i expected. And that's never a bad thing.

Special mention for the format and design of the book. Soft cover. Thick, glossy pages but not too glossy (if you know what i mean.) Round corners.

And now for the traditional tour of some of the works presented in the book:

Regina José Galindo, ¿Quien Peude Borrar Las Huellas? A Walk from the Court Of Constitutionality to the National Palace of Guatemala, leaving a trail of footprints in memory of the victims of armed conflict in Guatemala, 2003

In 2003, Regina José Galindo walked from the Congress of Guatemala building to the National Palace, dipping her bare feet in a basin filled with human blood, leaving red footprints behind as a protest against the presidential candidacy of Guatemala's former dictator José Efraín Ríos Montt whose military regime committed widespread human rights abuses.

Between 1976 and 1979, Keith Arnatt photographed dogs and their owners out for walks near his home in South Wales. The artist went to great lengths to ensure that the owner and his pet are looking at the camera at the same time.

"Where the photographic act is concerned, a dog's attention span is extremely short. When, for example, calling a dog's name fails to attract its attention, I am forced to resort to more extreme measures."

"My barking and growling are quite effective, though such antics tend also to affect the owner's own response. And though a fair number of pictures do show the dog making the required response, they are marred by showing the owner peering down to see whether they are doing so."

The Work in Progress show of the Design School at the Royal College of Art opened a couple of days ago. I went twice and haven't moved beyond the Design Interactions department yet but i'm hopeful i'll get to see the works of the other departments over the weekend as well.

The department is showing some 40 projects this year. The variety of interests, means to explore them and degrees of speculation is remarkable.

View of the system at the WIP show

Philipp Ronnenberg's ongoing OpenPositioningSystem / openps.info is a very hands-on, concrete project that aims to offer an alternative to the dominant global positioning systems or other navigation systems which are controlled by governments, network companies or in the case of GPS by the U.S. military. These technologies are closed at the moment and can be shut down at any time.

OpenPositioningSystem, however, was developed in the same spirit as OpenStreetMap. It would be open, accessible to anyone and collaboratively run by citizens.

Here's how the system works:
The idea is to use seismic frequencies, produced by generators in power plants, turbines in pumping stations or other large machines running in factories. These generators, machines etc. are producing seismic activity, distributed over the ground. The sensor prototype can detect seismic waves on the ground, walls or anything with enough contact to the ground.

At the current stage of this project the sensor can detect and collect different frequencies.
To calculate the noise in a city out of the received signals from the ground, the sensor has to be tuned into a specific frequency. To get a specific frequency from one machine, turbine etc. the sensor has to be as close as possible to the seismic source to receive a clean and strong signal at least once. When three signals and their positions on a map are known, one can calculate the position within these three signals.

Seismic sources



In this early stage, the project will still rely on GPS and maps. With the process of expanding the new network of seismic sources, it can be possible to build a stand alone positioning system.

Testing the signal

Testing the signal

The designer is hoping to gather interested people on the web platform openps.info and build a community which will help him develop the software, hardware and testing processes.

I'll be back with more projects discovered at the show in the coming days. In the meantime, check out HFA's take on the Transfiguration dolls crafted by Agatha Haines.
