name: the Transparent Beehive, sculpture, year start: 2013, year end: ongoing, techniques: honeybee colony, plexiglass, wood, steel, sensors, microphones, webcams and streaming technology, realtime audio, data processing, size of the work: 175cm (H) x 95cm (W) x 75cm (D)

The Transparent Beehive is a living sculpture in the form of an observation beehive made from plexiglass, wood, aluminium and steel. Inside is a living bee colony that has access to the outside world through a plexiglass pipe. The Transparent Beehive was installed for the first time on a Brussels rooftop connected to an urban garden laboratory and has since been shown in various art contexts. It has helped to produce a variety of art works including sound works, visual images, and bee artifacts.

The beehive is internally structured like a book, as inspired by a design from 1788 by the Swiss entomologist Francis Huber, in order to make it easy to open the hive for inspections and for filming the activity of the bees inside the nest. Each page consists of a wooden frame covered by an aluminium casing and mounted on dry-lubricated sliders. Bees spontaneously build honeycomb structures on the frame.

Each wooden frame is enhanced with microphones which pick up the vibrations and sounds of the hive. They are sonified and made audible helping to monitor the health and development of the bee colony. Cameras inside the hive monitor the growth of the wax structures and the activity of bees. Additional sensors measure temperature, humidity, and other microclimate measures. Data is treated by sensory processing, pattern recognition and AI algorithms and visualized using sophisticated computer graphics algorithms in order to make the state of the colony tangible.

Sound is an important aspect of the Transparent Beehive sculpture. The microphones inside the beehive monitor continuously the colony’s buzz. When the sculpture is shown without a living bee colony, the Transparent beehive sound file is played. It is an elaboration of the field recordings made in the broodnest of the Transparent Beehive for a complete season, starting with recordings on june 21st, the longest day / shortest night, and edited into a 15 minutes-piece using Max/MSP.
The increase and decrease of swarm activity in the hive and its influence on the buzzing sound produced by the colony is the main thread for the transformation of the recordings. I thus use natural phenomena as musical tools and, in retrospect, musical tools as an artistic rendition or analysis of natural phenomena. The audio work embodies the bee swarm intersected simultaneously with swirling electronic sound clusters.

The Transparent Beehive is a living sculpture, part of a series of ecological instrumented beehives leading towards a fully biocompatible intelligent beehive. The Transparent Beehive allows the Brussels Urban Bee Laboratory to study the tight interaction between city honeybees and urban ecosystems, using artistic research practices and in collaboration with scientists.

My preoccupations with bees come partly from a fascination with these amazing insects: Bees exhibit very original solutions to the challenges that social insects face, e.g. on the level of communication and collective decision making. They are an endless source of visually stunning images and sounds and their remarkable collective behavior provides inspiration and metaphors for the functioning of human society.

I have also another motivation. In many industrialised nations, bee colonies are now threatened. There are many causes – amongst them pesticides and parasites – but the compromised state of the foraging areas for bees is just as worrisome. So I work also towards an improvement of the environment of bees with the creation of urban gardens and guerilla planting and I use bees as bio-indicators to make citizens aware of the increasingly negative effects of our life styles and methods of industrial production.

The Transparent Beehive, the movie.
The hive -housing a live colony- was shown in situ in Brussels during a complete Bee Season.

Music Information
By introducing the microphones inside the beehive, we have been developing a monitoring device that is based upon the continuous monitoring of the colony’s buzz: a non-intrusive scanning device for controlling the colony’s health & development. We also have been adding video monitoring (outside and inside), which gives us a full spectrum of possibilities for colony monitoring and environmental surveillance.
As bio indicators, honeybees provide us with a constant stream of information on the environment on which they forage, via their daily activity, and via the pollen and nectar they harvest.
Diseases like colony collapse disorder and environmental problems like the use of pesticides could be analysed in a different way by monitoring the colonies with audio and video tools, and by analysing their daily activity over multiple years.

The sound on the uploaded Transparent Beehive video is an elaboration of the field recordings made in the broodnest of the Transparent Beehive. The sound-behaviour of the bee colony was recorded for a complete season. For the sound of the uploaded video we started to work with the recordings from june 21st, the longest day / shortest night, and we edited them into a 15 minutes-piece on which some processing was done with Max/MSP. As a compositional principle different ideas around swarm formation were investigated.
The increase and decrease of swarm activity in the hive and its influence on its sound, became a guideline for the transformation of the recordings. Using natural phenomena as musical tools and, in retrospect, using musical tools as an artistic rendition or analysis for natural phenomena. The audio work tries to embody the bee swarm while simultaneously intersecting the swarm with swirling electronic sound clusters.
The soundpiece by AnneMarie Maes and Billy Bultheel exists both as a Stereo and as an 8 channel audio work, and was broadcasted recently by Kunstradio Vienna.

Bio AnneMarie Maes and the Brussels Urban Bee Lab
New media artist Annemarie Maes is the founding director of the Brussels Urban Bee Lab [BUBL]. She has for decades been a recognized leader pioneering art-science projects in Belgium, using highly original ways to bring out hidden structures in nature by constructing original technological methods to probe the living world and by translating that in artistic creations through sonification, visualization, sculptures, large-scale long-term installations, and workshops. She thus makes use of technological mediation to search for new forms of communication with the natural world.
In 2004 Annemie Maes co-founded the artist collective OKNO which has been active on the border between new media and ecology and using DIY and collective artist practices to find new ways to engage with the urban environment. In 2009 she founded the Brussels Urban Bee Lab as a spin-off from OKNO. It focuses on urban bee colonies as a vehicle for novel artistic practices to raise ecological awareness.
The Brussels Urban Bee Lab [BUBL] is an independent international collective of artists, scientists, beekeepers, technicians and creative people. BUBL uses artistic, scientific and technological research approaches to tackle challenges related to sustainability and the monitoring and survival of city honeybees. Bee colonies are currently threatened in Europe at an alarming rate and BUBL’s research is therefore of great importance, both by raising awareness and by providing unprecedented data for studying bee colony collapse disorder.
An extensive rooftop garden in the centre of Brussels hosts the headquarters of the BUBL laboratory. It is giving place to several experimental beehives and instrumentation equipment. From this laboratory, data is continuously being broadcast through streaming technology.
The Brussels Urban Bee Lab operates mainly through artistic installations and workshops. The group has produced several very original beehives and produced art works shown in international exhibitions. The installations explore highly experimental technologies, such as microbial fuel cells, digital and organic fabrication using OpenStructures, biomimicry, spatialised sonification, web-based continuous data streaming, data mining based on Artificial Intelligence, organic electronics, solar energy for powering low-energy computing, etc. The group collaborates with several universities and a network of artistic research centers throughout Europe.

Today’s professional mushroom growing is an energy-consuming process. But it is perfectly possible to grow your Oyster mushrooms, your Shiitake’s or lesser known edible mushrooms in an energy-friendly and ecological environment. This can be done with a minimum of work, time and space. Okno is inviting mycologist Ann Van Belle to introduce you into the world of mushrooms with a practical demonstration followed by a lecture and Q&T-moment. Continue reading


A forest garden is a garden modelled on a natural woodland. It has 3 layers of vegetation: trees, shrubs and herbaceous plants. In an edible forest garden the tree layer contains fruit and nut trees, the shrub layer soft fruit and nut bushes, and the ground layer perennial vegetables and herbs. The soil is not dug and annual vegetables are not normally included unless they can reproduce by self-seeding. It is usually a very diverse garden, containing a wide variety of edible plants.

Setting up an exhibition about today’s ecological and economical crisis is a delicate exercise: it seems that everybody has done one such exhibition before you and invited the same artists as you. This year’s edition of The Game Is Up! , a festival organized by one of my favourite art centers, the Vooruit in Ghent, Belgium, was brazenly titled How To Save the World in 10 Days.

interview with Vasu, facilitator at Barefoot College

Barefoot College has changed a lot compared to 36 years ago when we started. What is applicable in Tilonia – its overall vision – can be replicated anywhere else. In this country and abroad, but it needs a change of mindsets.
We are organized in a disorganized way. We have small committees for different topics. We have the housing committee, the water committee, the salary committee. Salaries can go up and down, depending on your performance. You have also the possibility to evaluate yourself. Poverty, teamwork, gender are all issues coming into play for evaluation. Points are added up, but nobody can get more than 100 U$.
The options are open. The organization is set up as a community so obviously there will always be somebody to run it. Continue reading


Four dark-skinned women in multi-hued saris hunch over a solar power-generating circuit at the National Institute for Rural Development (NIRD) in Hyderabad, fleshing out details about solar lamps and panels for Indian villages. Chennamma, Yelamma, Kalavati and Zayda, all illiterate women in their 30s who previously worked as stone crushers in South India’s quarries, have left the furnace-like heat of their previous jobs to use the sun Continue reading

solar engineer training at the Barefoot College

For videos on the solar workshops, check the category ‘media’.

At Barefoot College, ordinary men and women -whatever their qualifications- can learn about solar energy. Roles have to be flexible: the teacher can be the learner and the learner can be the teacher.
The whole environment is one of creative learning, demystifying technology and unlearning through processes that are natural, non violent and respectful.
At present time, 32 Buthanese girls and 6 Mauretanian women follow a 6 months training to become a solar engineer in their home villages.

They are selected by their communities to be trained in the installation, repair and maintenance of solar photovoltaic units. They learn the necessary skills to repair inverters and charge the controllers for the solar units they will look after.
Every family of the remote village communities pays a small sum for the equipment and the services of the solar engineers. As such, every member of the community takes his responsability in this ecological project of sustainable energy.
