Visiting Peace Garden Lung Ta

As part of our explorations during the months of March, April and May we have come across the Lung Ta Peace Garden near Olot in Catalunya, on the foot of the Pyrenees.

Essentially centered around a charismatic leader, Isabelle, the 72 year old woman leading the community, is not dogmatic in any way and has managed to create an incredably tolerant, respectful and free atmosphere which reminiscents of reuniting with long lost family.

At Lung Ta (Tibetan for Windhorse) there is ample space for personal development through yoga, meditation and contemplation. With regards to the latter, Tibetan and Mayan thought and mysticism form a central nexus based around the Law of Time.

Along with spiritual aspects, good company, food and drink and loving attention amongst members and visitors alike, together with the wonderful surroundings of nature bring about a true appreciation of quality of life and connected unaliable human freedoms.

While currently the gardens do not fulfill a significant part of the nutritional needs for the members and visitors, hard work is being put to extend these efforts. As with other aspects of this community, members and visitors are actively invited to creatively contribute however they can to create a more sustainable, self-sufficient and autonomous community.

Conditions for a new long wave of economic development: revisiting the low road / high road scenarios

Grassroots and commons-based productive movements must of course continue their efforts, and the negative orientation towards more and more inequality (and surveillance/repression), and biospheric destruction are largely unchecked. However, it is also important not to be blind to real adaptations that are effectively occurring within the dominant system.

Vesna Manojlovic: Leavers, takers and commonism

Vesna, from the hackerspace in Amsterdam, is providing an interesting perspective on the history of ‘modern’ humans and their relationship to other humans and species. In this poetic and graphic description, she quickly touches on commonism as an ideology and poses the question: will internet and computer networks enable us to face the challenges that lie ahead of us?

The idea of leavers and takers presented here originates with author Daniel Quinn whose books Ishmael, The Story of B and Beyond Civilization are a source of inspiration for Vesna and many, including Pearl Jam whose album Yield was inspired by it.

This beautiful video, including animation, was created by Irene van Carmen. Original material recorded by Mathijs de Bruin. Music by Presidente (Av 18, Corina, Réquiem) and Ricardo Villalobos (Das leben ist so anders). Audio mastering by Erly José.

Welcome to your Post-Capitalist future

Are you ready for the change?

Tear gas burns the eyes, nose and skin. Without access to first aid, there’s not much you can do but run for cover and try to wash it out with water – or cry it out. The air was thick with the acrid gas as the global financial crisis hit Greece in 2008, which set in motion a debt crisis the country is yet to recover from. In December, young Greeks faced off with riot police in Athens’ Syntagma Square and anger towards failed economic policies came to life in billowing plumes of yellowy smoke.

While tear gas may cause temporary sensory deprivation, it can also lead to moments of clarity. Or, so it was for writer Paul Mason. As Mason watched events unfold on the streets of Greece, he cast his mind back to September that year: wandering around with a TV news crew outside the headquarters of the collapsed investment bank Lehman Brothers, as newly redundant employees put their possessions in cardboard boxes and went home for the last time. He thought too about how he’d seen the internet reshaping society since his time as a tech journalist.

Mason began to connect the dots: this crisis isn’t going away. This train of thought led him to his provocative book Postcapitalism: A Guide to our Future. Mason offers a terminal diagnosis of the current order and a glimpse of what a new world might look like – and its seeds are already visible all around us.

Fossil fuels are finished – the rest is just detail

After a more than century of domination, the global fossil fuels industry is now in terminal decline, and will be all but gone within 15-30 years. Politicians must recognise this fact, or risk making serious and damaging mistakes in climate and economic policy, in investment strategy and in geopolitics and defence.

Books from the Decentralibrary


In the last couple of years, several authors have inspired a vision of a more decentralized, equitable and free society. This is the first in a series of articles in which books that play an essential role in projecting this vision are highlighted. In the current article we will explore the borderline between science and philosophy: first, mathematics with Nassim Taleb’s Antifragile. Then complex systems theory with De Landa’s Nonlinear History. Lastly, Latour’s refutal of modernity in We’ve never been modern. Lastly, we discuss Hofstaders Strange Loop on emergent behaviour and consciousness.

by Nassim Taleb

Feared and heralded for his almost anti-academic stance, Nassim Taleb is a mathematician and finance expert who, through his practical experience in finance, has developed a unique perspective on statistics. He argues that the events that lead to changes in the (metastable) equilibrium of complex systems (i.e. all of nature) are of a rare and necessarily unpredictable nature.

Within this framework, he is able to assign a property to systems based on their reaction to rare (high sigma) perturbations. He classifies systems on a scale ranging from fragile (systems likely to break under perturbations) through resilient (systems that will not change under perturbations) to anti-fragile systems which gain in strength under perturbations). Based on this analysis, he theorises that many of society’s current structures such as the nation-state and our current financial and monetary systems are inherently fragile and will eventually collapse.

At the same time, his theory also gives us quantitative and qualitative methods for assessing the fragility of any system based on its inherent (rather than derived) properties. This as opposed to statistical methods, which require explicit modelling of systems and historical data to make statistical predictions, often lacking in precision due to limited significants for rarer events. By classifying systems into antifragile, fragile and resilient we can optimise systems and structures for volatile environments such as our very own habitat. This is particularly true with regards to our near future, in which prolonged and simultaneous perturbations should be expected due to the destabilization of climatic (due to global warming and loss of biodiversity) and economic systems (due to resource scarcity and depletion).


A Thousand Years of Nonlinear History 

by Manuel De Landa

In this very refreshing piece of modern philosophy, Manuel De Landa presents a materialist perspective on recent history. Rather than assuming a traditional ‘flat’ linear history, he applies ideas from systems theory and complex systems analysis to yield a history in which essential turning points are shifts and jumps in emergent saddle points under perturbations. It suggests that many historic lessons can be learned by looking at flows of resources, in the form of material and information. For example, the way we have historically short circuited food chains as to provide in our growing needs tells us a lot about the mechanisms behind and conditions for urbanization. Similarly, the rise and fall of disease patterns sheds light on the institutionalization of society.

One of his main points is that complex systems tend to organise themselves in networks that are either mesh-like and more decentralized or tree-like and stratified or more centralised. Most systems exhibit characteristics of both but have a tendency for one or the other. Within this perspective he suggests a tendency for Western society to slide towards more centralised, hierarchical structures. This goes for material resource flows as well as the distribution of power and information and, as such, provides insights in why and how our society is as centralised as it is. At the same time, this provides an anchor for imagining more decentralized mesh-like forms of interconnectedness and organisation.

You might guess by now that grasping the full depth of De Landa’s thinking requires a rough grasp of many scientific disciplines, not the least of which are physics, biology, social science, economics, linguistics and systems theory.


We have never been modern

by Bruno Latour

In yet another French refutal of structuralism, Bruno Latour argues for a non-dualist perspective on science. He repeatedly attacks the modern distinction between nature and culture, as he did in The Pasteurization of France with the classical dichotomy between constructed and real entities.

Latour argues, rather, that the very nature of dichotomies limit and colour our analysis of phenomenon. To avoid this trap, he proposes his ‘Actor-network theory’ which does not make a priori classifications of elements under analysis; hence atoms have the same ontological status as visions, animals, trees, planets or humans. Using this extremely flexible pseudo-ontology, Latour’s analysis is employed successfully to expose blind spots in our perspective of reality.

He has applied this methodology to expose the formulation and dissipation of scientific concepts and how they became part of this reality in Science in Action and the The Pasteurization in France. In Politics of Nature he applies it to argue for an equal political representation of humans and non-humans (e.g. elements of ‘nature’) alike.

His methods of analysis, as well as his analysis of scientific practises and social self-reflection have been of tantamount importance to expose seemingly evident structures in our societies and consciousness. By not allowing ourselves to take any distinctions for granted, we are moving in an ontological space that is continually shifting, mapping out blind spots as we are forced to change perspective.


I am a strange loop

by Dougles Hofstadter

It might seem strange to mention Hofstadter’s classic on consciousness here, however, I have never read a more accurate description of emergent behaviour and downwards causality than the one posed in this book.

In ‘I am a strange loop’, Hofstadter pursues the viewpoint that consciousness is a phenomenon that spontaneously emerges out of a certain amount of symbolic representative capacity of our cognition. In simpler words; when putting enough brain cells together, with the right amount and sort of interconnectedness, creates a feedback loop which we conceive of as consciousness.

His theory about consciousness has the advantage that it does away with the ‘je ne sais pas’, the soul or hidden essence, often found in similar theories. This not only makes consciousness material and (metaphysically) ‘nothing special’, it also allows the conception of higher order forms of consciousness, such as collective forms thereof. Imagine groups of people with complex emergent behaviour and feedback loops, creating a group awareness as real and as fundamental as the individual awareness.

As part of imagining a different society, we cannot escape the fact that we need to think above and beyond the level of the isolated individual. In the same way that Hofstadter’s theory allows us to understand the emergence of individual consciousness from underlying feedback loops, his framework of thought might also allow us to understand the emergence of collective consciousness, identity and individuation. A more thorough understanding of the origination of collective consciousness might again help us to imagine emergent ‘bottom up’ social structures and organizations, the collective of which might be complex enough to compete with and surpass current socio-economic systems.

The possibility of a decentralized society

Strangely enough, all of the discussed philosophers happen to be alive and kicking at the time of writing this article. This is purely accidental and, surely, their work would not have been possible without all the babblers, thinkers and crackpots and, in general, the monstrous magma of human culture which forms the context for our conceptual understanding and cultural experience.

These thinkers are, unwittingly, helping to form an image of a possibility, a possible path through which we can structure social and economic dynamics to last. The decentralized nature of this projected vision allows for ‘horizontal’ reproduction of ‘bottom-up’ emergent structures. This would allow new and presumably better equilibria ‘stable states’ without the force and violence that is traditionally associated with large-scale societal change.

We’ve never had it so good - panel discussion at Oxford university

During a speech in 1957, Prime Minister Harold MacMillan declared “most of our people have never had it so good”. Now, more than half a century later, are we fundamentally any better off? Through discussion of technological advances, social changes, political reforms, and economic shocks and recessions, this panel will seek to question whether the world we currently live in is indeed a better place than it was in the 1950s.

E-waste Republic

The West African country of Ghana, currently undergoing intense economic growth, is an important centre for receiving, re-using, recovering and disposing of electronic waste. Accra, the capital, hosts a thriving second-hand market, a sprawling network of repair shops, and a range of activities which attempt to tap into the full potential of e-waste. And yet, it is also the location of an enormous and heavily polluted electronic waste dumpsite.

Decentralized energy: Nailing the Microgrid

Designing the Internet of Energy


When Nikola Tesla developed our current electrical system in the beginning of the 20th century, he meant for it to be an intermediate state between an unelectrified and a fully electrified world where energy would be shared freely. Due to market forces and perhaps his overestimation of human capacities, his vision of free, sustainable, energy for everyone was never fully realized.

Ever since we have been stuck with the prototype for an electrical system from the 1920’s, requiring a fully centralized top-to-bottom design and being increasingly maladjusted to today’s electrical generation, transport, storage and consumption requirements. In Tesla’s time AC (alternating current) was the only way of converting electric potential from high to low voltages and vice versa, allowing for long distance transportation of energy. Moreover, as cheap abundant fossil resources where available, storage and efficiency requirements where minimal.

Nowadays, the scarcity of fossil fuels (and severe damage to the environment) make sustainable generation and the storage of their intermittent production an absolute necessity. As such, it seems that all of the significant options for sustainable energy production (wind, PV, CSP, tidal) represent essentially DC (Direct Current) sources. The same is true for storage solutions (though some production and storage solutions produce AC, this is not of a fixed frequency and requires prior DC conversion regardless). Moreover, virtually all modern household and office appliances are essentially DC devices, requiring rectifiers and DC-DC voltage conversion for each and every device.

With the current advancement of fast, reliable, cheap and efficient switching electronics (like IGBT’s and power MOSFET’s) together with widely available DSP’s and microprocessors, the conversion of DC voltages has become at least as efficient as AC-DC or AC-AC voltage conversion, but requires less and cheaper parts. As both generation, storage, production and transport are more efficient using DC, the overall system efficiency can be significantly increased.

At the same time, a fully integrated DC grid would greatly simplify the implementation and design of smart microgrids as no power factors, resonances or induction losses need to be taken into account. With DC technology, units of production, storage and consumption can be seamlessly connected in an ad-hoc fashion in self-sufficient microgrids while increasing resilience and reliability.

In addition, a DC grid would be fully bidirectional and thus ‘smart’ from the very start, requiring only minimal management, creating the potential for small communities to manage their own sustainable electrical supply. As the current centralized AC grid architecture is fundamentally limited in the degree to which (intermittent) microgeneration can participate, moving to a full DC grid provides a fast way forward to fully renewable energy production.

In this context, we see the free spread of technology and knowledge as key factors to allow both for wealthier economies to reduce their footprint at a pace in line with environmental requirements as well as to allow developing economies to increase their standard of living with a minimal impact on the environment. Because of this, the software, hardware and overall system design and other documentation available to the general public for use, modification and re-distribution.

Nikola Tesla aimed for a globally coordinated, integrated, energy grid but failed tragically. Instead, we count on human autonomy and decentralized collaboration to allow groups of people to gradually break away from traditional AC systems by building their own, interconnected microgrids. The idea is to learn by doing, building an Internet of Energy and develop, document and refine the technology one community at a time, while retaining full interoperability with legacy AC systems, demonstrating a path for an accelerated transition to decentralized, sustainable energy.

The Internet of Energy

Similar to the transfer of streams of data on the worldwide internet, electrical energy could be routed and transferred with very high efficiency from sources to their of destinations without central management technology. A similarly created Internet of Energy would natively exhibit self-healing properties by providing for redundancy and islanding. It would not allow for nor require central management and as such would enable communities to autonomously produce and exchange energy while maintaining control and privacy.

How the internet works

In order to study the design of an Internet of Energy we need to first look at some of the core principles behind the design of the internet to find out how such a complex system can show such miraculous stability.

In the 1960s the DARPA, the US defense’ advanced research projects agency, designed the ARPANET, a computer network able to extendibly connect many individually managed computer networks. The ARPANET was designed to maintain functionality while suffering losses of many of its constituent components. It did so well that it grew out span the globe and has now been called the Internet, being a network of interconnected networks.

The internet consists of many interconnected Autonomous Systems. These are individually managed networks with different architectures, topologies and capacities, which are connected through so-called Border Routers. Within Autonomous Systems, individual systems, called Nodes, are connected through ordinary Routers. It is these fundamental design elements of the internet which we will reapply within the context of routing electrical energy.

Routing electrical energy

In traditional systems electrical energy is distributed top-down, from a few large power plants producing energy at immense voltages down to many small houses and electricity sockets. In these situations electrical energy typically flows in a single direction, from high-voltage generation down to medium-voltage distribution down to consumption.

In distributed production scenario’s, where decentralized microgeneration is the main source of energy, this is not so straight forward and energy can essentially flow in any direction. But how to get the right amount of energy in the right place, how to assure that enough energy is available and how to assure that an outage in one side of the net does not take the rest of the net with it?

The Energy Router

Meet the Energy Router, an semi-autonomous agent able to control and measure the flow of electrical energy between and within Nodes, which represent individual units of consumption, storage and production (like households, buildings or administrative units). It essentially forms the border point between the Internal Network working on a lower voltage and the microgrid. The task of the Energy Router is to regulate demand and supply of energy, co-maintaining the grid’s stability as well as that of the Internal Network.

The Energy Router gathers data and controls energy sources like Maximum Power Point Trackers (MPPT) for solar panels, Battery Management Systems (BMS) and communicates directly with appliances or their power supplies as well as the Energy Router’s of other Nodes.

While being internet-connected the Energy Router essentially performs its tasks without, communicating with other Energy Routers by changing voltages. However, when an internet-connection is provided the Energy Routers in a network form an intelligent multi-agent system. Collectively, the routers are able to optimize storage, supply and demand by negotiating current and future (predicted) requirements and availability of energy as well as integrating external information such as weather data from third parties.

The Autonomous System

On the Internet, an Autonomous System is an independently managed network and in The Internet of Energy this is much the same: Interconnected Nodes form Autonomous Systems that are opaque to the outside world and will function regardless of and autonomous from it.

An Autonomous System is made up of interconnected Energy Routers. Most of these connect full Nodes with an Internal Network, others will directly connect storage or generation capacity and yet others might have the task of Border Router, connecting an Autonomous System to other Autonomous Systems or to the legacy grid.

Smart topology

The Nodes in an Autonomous System are linked over Point to Point connections, links between a single Energy Router and another. In this way an Energy Router can be connected to one or more other Energy Routers with a Point to Point link for every connection. As opposed to traditional grid systems, which typically have a hierarchical 'tree’ structure, The Internet of Energy follows a mesh topology where any Node can be connected to any other Node, increasing flexibility, redundancy and efficiency.

Privacy and internal accounting

Because capacity for production, storage and transport within an Autonomous System is managed by the owners, typically a community of users, the usage of the system can be expected to be fairly balanced amongst Nodes. Nevertheless, because structural imbalances add up over time, it is important to keep an accurate ledger on the balances between nodes. Especially in dense environments with continuously changing circumstances and varying degrees of trust between users, the need of authoritative accounting will arise.

This task is traditionally performed by a trusted third party like a network operator, who sometimes even stores your data 'safely’ and 'with respect for privacy’ in 'the cloud’. However, modern blockchain technology (as pioneered by Bitcoin) allow us to perform trusted tasks in a fully decentralized manner. Because power is measured on both ends of the connection between Nodes, they are in a position to validate one another’s findings. After agreement has been reached, values are added to the Autonomous System’s internal ledger (in the form of a blockchain). The numbers are then cryptographically signed so that undetected tampering becomes a mathematical impossibility.

However, because this data is managed within the Autonomous System’s infrastructure, and preferably encrypted using a public key infrastructure (PKI), the privacy of the users is maximally protected; from the outside only aggregate data is shared about the delivery to and from other networks through a Border Router.

The Border Router

The border router connects one Autonomous System to another, or to legacy grids and essentially sells excess energy or buys energy when local generation and storage capacity are insufficient. This makes it an autonomous market agent, algorithmically selling and buying short-term futures based on predictions and knowledge about the state of the Autonomous System combined with market circumstances.

As such, it makes sense to allow the algorithms to occasionally sell of stored energy to perform peak-shaving services for neighbouring systems, for a profit. This could be electric vehicles selling back a fraction of their energy to power known short-term loads or households selling battery-stored energy to nearby industry during the day as plenty of wind energy is predicted during the night.

The energy market might be one of the few markets where price determination down to the millisecond could prove to be constitutive to the environment rather than deteriorative.

Copyleft and Open Source technology

Smart grids and sustainable technology are typically imagined in urban contexts in well-off economies, however the short term (efficiency and monetary) gains in these contexts are limited due to the amount of legacy they have to sustain (and fight) and the small gains in comfort they yield. In contrast, for many emerging markets and less fortunate societies the promise of a cheap, autonomously controlled and stable supply of electric power yields tremendous advantages.

Though often the current lack of infrastructure is the result of political and/or economic factors, sometimes technological factors might avoid these hindrances (think mobile banking in Africa, for example). Providing cheaply available, simple technology to ascertain primary services (like electricity) helps these societies’ infrastructures evolve, creating a positive feedback into the political and/or economic domain. At the same time it helps the technology grow and develop, through economies of scale and (literally) battle testing.

However, developing smart grid technology and then patenting and copyrighting it is not the way to get it adopted in economies that cannot afford to pay for the licensing costs. Developing it and waiting for Chinese clones will not aid in the further development and global economies of scale. Furthermore, it will not allow people and companies alike to produce components locally.

Developing the hardware and the software for The Energy Router, The Border Router and, eventually, the DC/DC and AC/DC converters in the public domain does. Having standardized components that are designed for flexibility and simplicity freely available for usage, modification and (re)distribution creates an enormous potential for growth of smart grid technology and hence for sustainable development and emancipation of societies.

Modularity and maintenance

In current renewable energy systems critical components such as a battery management system (BMS), a maximum power point tracker (MPPT), an inverter and data logging (smart metering) functionality are often integrated into a single device running proprietary firmware. This has the advantage of increased material- and cost-efficiency and integrative optimization (tuning) of the separate parts. There are, however, the risks of accelerated deprecation and difficulties in long-term maintenance.

Typical lifetimes for decentralized renewable energy systems can be expected to be 20-25 years, corresponding to the typical lifetime of photovoltaic panels. However, given the exponential trend in cost reduction as well as global application of the technology, major technological breakthroughs as well as significant cuts in their application costs can be expected for most parts of the system. This means that, similar to the exponential trend in IT, repairing devices as part of maintenance will be more expensive both in terms of monetary costs as well as in resource use due to increased efficiency.

Rather than designing one system that needs to be replaced regularly during the lifetime of the renewable energy system, risking compatibility and increased difficulty in maintenance, it would be desirable to aim for a modular approach where a single Energy Router is able to use a myriad of protocols and busses to communicate with a host of different current, future and legacy devices connected to the grid. As the core role of the Energy Router is communication with other devices, its (cheap) hardware needs to be upgraded only occasionally while its software can be continuously updated and maintained.

Instead of having a single device which cannot be extended, updated nor modified and requires proprietary knowledge to be maintained, working with generic devices allows for seamless upgrading, repairing and replacement of parts. This offers users a tremendous flexibility in the design of their energy system, being free from a vendor lock-in, potentially allowing them to do their own maintenance while still using the latest technology. Paradoxically, it would also significantly reduce the amount of hardware that gets wasted.

Similar to the way the Linux operating system allows people to still use old computers, having legacy support for older devices will allow people who would not otherwise have access to advanced renewable energy systems to use deprecated technology makes access more equitable while reducing the overall manufacturing costs.

Another comparison might be in the hifi domain. Think of how many discrete vintage amplifiers, tuners and record players are still being put to use, now compare this to the rapid decline of modern cheap integrated hifi towers from our environment. While cheaper, more compact and advanced, the integrated hifi towers with their double deck tape players, digital tuners and 12-bit CD players quickly faded away because their individual parts could not be repaired, replaced or (in case of the cassette player) simply removed altogether.

Resilience and stability

The protocols and technologies enabling the global internet were designed such that one failed system, network or link could never disrupt the functioning of the entire network. With systems of this kind of complexity, disruptions, faults and degradations are a given. Hence, resilience against perturbations is a must.

It is common knowledge that electricity networks in the developing world are often lacking in stability. However, it is less commonly known that even in developed parts of the world centralized hubs of energy interconnects allow for the propagation of faults across networks. This is what caused the 2003 Northeast Blackout in the United States and the blackout in all of Italy in the same year.

Taking in mind that the aforementioned blackouts occurred due to human and system failures of the system, we could only imagine the security implications when electricity systems are systemically and strategically attacked. Such is the case in areas struck by (civil) war, such as Irak, where insurgents are continually attacking and disrupting services such electricity and water supply.

The fundamental cause behind these vulnerabilities to natural and intentional perturbations lie in the scaling behaviour of centralized systems. Regardless of the amount of redundancy in the system design, the very fact of the design’s centrality yields hubs that provide single points of failure and vectors for fault propagation.

As with the internet, a decentralized electrical system’s stability would benefit from increases in scale. Rather than being maximally interconnected, the border routers in this system allow for containment of faults or ‘islanding’. This way the potential for global fault propagation is ultimately limited at the expense of a minimally decreased resilience of the autonomous system.

Experience learns that the islanding approach to systems resilience prevents global failure of the system. At the same time, it facilitates accelerated diagnosis and recovery of the faulted system as an autonomous system is limited in complexity.

Lastly, because the individual nodes within the autonomous system often provide for their own storage within the internal (in-house) electricity systems, only longer disruptions of the local system will affect the electricity supply.

An ongoing effort

Worldwide, several commercial and non-commercial parties are working towards the implementation of some or all of the described technology. Several small-scale pilot implementations for DC grids have been established and power conversion parties like Vicor Power and TDK-Lambda are actively pushing power conversion technology.

In The Netherlands, the European and perhaps world’s leader in direct current smart grids, Direct Current B.V. is working on decentralized smart grid technology that follows many of the mentioned principles. They are currently working to scale up their implementations and to establish open standards for the wiring, implementation and communication in DC smart grids.

On the academic end there is the (now completed) DCC+G research project and there are groups at Fraunhofer in Germany and the Intelligent Systems group at the Center for Mathematics and Informatics (CWI) in The Netherlands working in DC smartgrid technology. Then there is The Green Village cleantech playground and pilot site at the TU Delft, in The Netherlands.

Meanwhile, in the United States, the Emerge Alliance has set up an ‘open association’ with standards and certification for compatible DC wiring and appliances, accessible for those who pay for membership. 

On the Open Source front, the researchers from Open Source Ecology are looking to implement a Universal Power Supply, that looks like it could be a good candidate for the hardware of the Energy Router, once and if it’s developed. However, they are actively looking for an experienced electrical engineer to do the groundworks.

Then there is the  Open Source battery management system by the Canadian Dacian Todea, engineered for batteries and controller to outlast your solar panels. While designed to fit unconnected off grid systems, the fact that it is Open Source might pave the way for modular extensions. Having the controller there, it being high quality and Open Source proves, for one, that it is possible.

Lastly, there is yours truly, studying the feasibility of a domestic DC microgrid for Schoonschip, a self-sustainable floating community in Amsterdam, through the systems consulting and cleantech development firm Metabolic.

Being part of a circular redevelopment of the neighbourhood of Buiksloterham in the North of Amsterdam, the objective is to make Schoonschip the most sustainable floating community in the world. This goes with respect to material use, construction practises, water systems, heating as well as electricity.

The current article is the result of the last months of research, as is the publicly available knowledge base (on Hackpad) that backs it. The project is still in an early stage and I hope to be making contributions along the way. Consider the knowledge base an openly available notepad, internal documentation that is external to begin with - true to an Open Source development approach.

Now, to get you involved: please feel free to comment on this post, start a discussion, ask questions, read the Hackpad and: contribute to a future of free (libre), communally controlled, locally produced energy!

Driving towards MMK2015

This summer I will be spending one month at MMK, a ‘bootcamp’ for sustainable living in the beautiful area of Lika in Croatia. What is remarkable about this area is that it has, essentially, been left untouched by humans for about 20 years. 

The devastating effects of the Yugoslavian war has caused a reduction of the population from 15.000 before to a mere 1.000 today, leaving nature to reclaim the land. And it has.

With less than a promille of the surface area used by intensive agriculture, the hills covered by forests and the meadows juicy grass cut for the sake of feeding cattle elsewhere. 

Before, all hills used to be grazed by cattle. Now, 40 centimeters of very nutritious (clayish) topsoil covers the land. It has never seen chemical pesticides or industrial pollution. Could this be a haven for ecological agriculture?

This video is the drive from the nearby village of Lovinac to the MMK location. During the month I am here I will be doing a follow-up with Kruno Jost, founder of MMK, and one with the major of Lovinac.


What’s the Real Problem With Urban Agriculture: Misinformation



In this guest post, Blue Planet Consulting summer intern Ben Mickel responds to this recent article critcizing urban agriculture: What’s the REAL Problem with Urban Agriculture by Harkyo Hutri Baskoro


Before trying to answer what the problems with urban agriculture might be, lets first define what exactly urban ag is: Urban agriculture is the practice of cultivating, processing, and distributing food in or around a village, town, or city. (Bailkey, M., and J. Nasr. 2000. From Brownfields to Greenfields: Producing Food in North American Cities. Community Food SECURITY News. Fall 1999/Winter 2000:6)

This is a complex industry that exists at the intersection of Horticulture, Technology, Urban Planning and Food Security.  There is so much positive support coming from the community and an influx of capital is driving the expansion of high tech urban agriculture around the world and sometimes its difficult to know if its all just “hype” or really part of the future of cities. 

Growing Food in the Middle of the City is only Half the Story

Let’s address some of the cons Baskoro raised about Urban Ag. The first issue Baskoro addresses is whether or not it is “worth it to farm in the middle of the city” despite the fact that still most urban agriculture occurs not in the heart of most cities but in the peri-urban areas. In fact, some of the greatest opportunities for urban agriculture lie on the edge of the city where the land is cheaper but access to infrastructure and customers is still high. Lets stop thinking about urban agriculture simply as picturesque farms in the city and start determining how we can feed more of the city from nearby sustainable farms.
