Closing moment of HOOPGAS TestLLLab, a period of artistic research in public at Natlab / Baltanlaboratories in Eindhoven. With talks by Bartaku and Fred Keijzer, a philosopher from Groningen Univ., who will present some findings on cell / bacteria / plant cognition.
HOOPGAS is a continuation of work on/with the agave plant and its “ambience” (Cf. Timothy Morton, Ecology Without Nature (2009)). It departs from the observation that the Woman-In-Law´s Tongue, agave of the Lower Countries, seldom comes to flowering. But what if we would bring in the hormones, from the banana f.i.?

Co-creation experimentations with Bartaku on intimate sunelectric taste and representation of the eternal struggle for access to energy. The tPED Worklabs series are based on the first observation of the e-tickle on the tongue on October 21st, 2010, at Bartaku's homelab. They consist of experimentations on the transformation of light energy into electric energy with food. By fusing alchemistry, cooking and solar tech and designs, the co-creators will work with edible materials to create 'e-bites' with different aesthetics, tastes, consistencies and smells. To be tested, tasted and appreciated on heliotropic tickling tongues.
The tPED-Worklab-series are fused by PhoEf: The Undisclosed Poésis of the Photovoltaic Effect; an artistic research project by Bartaku.
PhoEf is a research project by Bartaku [Bru/BE] with explorations in the micro and macro realms of Photovoltaics: the conversion of light energy into electrical energy. It is situated at the interstices of arts, science and technology. The content of this micro-site is PhoEf's digital compost which fuses micro-interventions, workshops/-labs, writings and lectures.
PhoEf emerges from a personal, transversal flight through the interconnected worlds behind and around photovoltaics; a technology based on A.E. Becquerel's 1839 observation of the photovoltaic effect.
As photovoltaics illustrate the interwovenness of matter and mankind, with the elements and the cosmos, it promises to trigger a deeper understanding of the qualities, origins and movements of light. Of the Sun. PhoEf provides both sky and earthbound information, sometimes structured alongside linear vertical paths, only to make an abrupt stop. Finding junctions between intuitive text and the flowing of new (inter)connections in an attempt to reach, inspire and connect researchers, developers and artists.
As light is the primary source of energy of photovoltaic technologies, they are subject to the schizophrenia of the photon's behaviour as both wave and a particle, their multiplicities; healthy to dangerous, subtle to aggressive, absent to abundant and from invisible to tangible. Might it lead to just enough energy for an electric kiss, or to the rise of a Buddha? PhoEf wants to contribute to a further dynamic exploration of the complex relation between light, electrical energy and the media that can be used to represent it.

[…] “In investigating the roots of our current environmental dilemma and its connections to science, technology and the economy, we must re-examine the formation of a world view and a science which, by reconceptualizing reality as a machine rather than a living organism, sanctioned the domination of both nature and women. The contribution of such founding 'fathers' of modern science as Francis Bacon, William Harvey, René Descartes, Thomas Hobbes and Isaac Newton must be reevaluated.” Carolyn Merchant in The Death of Nature, 1980 crosstalks_reflection_bartaku.pdf

After having swum to the Tori (bird perch) shrine with my youngest sister, we observed it from the Island's sand beach. Not noticing that our skin was becoming rapidly a reddish radiating heating. One year before, sudden and brutal movements of the Earth's skin had a severe impact on its inhabitants. For many Japanese looking in the mirror became an ordeal as their belief of having mastered nature and their small outstretched piece of rocky and mountainous land, collapsed together with earthquake resisting dwellings, buildings and bridges.
The sun, the mirror and the cock on it's 'Tori' play an important role in Japanese mythology. Amaterasu OmiKami is as the Sun goddess virtually the supreme deity as well as the ancestor goddess of the imperial family. There are several versions of this creator story. In the in Kojiki (712 C.E.), Amaterasu ruled over the Kami, those small beings that help everything grow. Born from the left eye of her father Izanagi, her glow helped the rice grow, made the flowers bloom. Her beauty radiated such that everyone who felt it on their skin felt beautiful themselves.
Amaterasu's brother, Susano-O was the impetuous and violent god of storm. They never really got along, but were always drawn to each other like magnets. Susano-O would often go to seek out his sister in order to bathe in her calm radiance. And when things grew stagnant, he was the only one who could get them moving again.
After feuding again with his sister, Susano-O threw a dead horse amidst Amaterasu's weaving maidens. The deities were so heavily shocked that many of them were heavily injured and some of them died. When Amaterasu heard about the incident, she was so appalled that she hid herself in a deep cavern in the center of the earth and sealed it with a huge rock. The world plunged into a cold darkness and the Kami entered a death-sleep.
The senate of 800 Gods gathered in front of the cave with the Eight-Handed mirror and curved Jewels which they hung on the sacred Sakaki tree that was located outside the cave. By means of these devices, they hoped to beguile Amaterasu into believing that there was light in the world even in spite of her absence. They started a loud party and as they hoped, Amaterasu became curious. As soon as she peeped from the mouth of the cave; the cocks began to crow, the jewels glittered, and the mirror hanging by the tree reflected her light. She thought that there must be someone or something equal to herself illuminating the world. Finally, impressed by her own beauty, she decided to stay, filling the world with light and warmth, awaking the Kami from their death-sleep…

Bartaku, Edinburgh, September 2007
Since plants and photosynthetic bacteria lie at the base of the food pyramid, all life on earth is ultimately solar powered. The oxygen-rich surfable atmosphere of the Earth is the work of plants. It is a by-product of photosynthesis, the biological use of the Sun's energy to make molecules. 3,5 billion years ago, algae were photosynthesizing when the continents were newly formed and ungreened. These algae were the first 'autotrophs' (self feeders), making their own molecules from little more than light, water and carbon in the air. Plants and algae explain the bluegreen color of the Earth. 1)
We will not address the question Why this happened but it is clear that recorded history of mankind indicates a deep understanding of the crucial impact of the Sun (light) in the form of solar deities or other supernatural fenomenon, rituals, sacrifices, calendars (Sun dials), monuments, poems, plays, music, movies etc. It might be useful to get a more personal and intimate understanding of light combined with some scientific knowledge.
The Sun, the hearth of affection and life, pours burning love on the delighted earth. Arthur Rimbaud (1854-1891)
Before looking at some science based information about the Sun light and its conversion into electricity it might be interesting to introduce some Sun-awareness-building exercises to sharpen the senses like a pencil in a Planetary Pencil Pointer.
Rules: Observation only; no rationalizing, comparing nor describing. Do not look longer into the Sun than 100sec.
Recommended conditions: perform the exercises on your own in a distraction free environment. Do them repeatedly in each season in the morning, at noon, dusk and evening. Except for exercise 9, 10, 12-14 the sun does not necessarily have to be visible.
1.Close your eyes as tight as possible. Turn your head towards the spot where you observe the most light. Then gradually, very, very slowly open up your eyes. Try to keep them open as long as possible (don't try too hard) and then close them instantly and fiercely. Observe what you see.
2.Breath in and out through your nostrils at a natural pace. Observe what you smell.
3.Take out as many clothes as possible. Close your eyes and scan your body gradually, slowly from the top to the bottom. Observe the sensations on your skin.
4.Breath in through your mouth at out through your nose. Observe the sensations, the taste on your lips and in your mouth. Observe how it travels through your body. If and how it leaves it.
5.Focus on what you hear. Try to listen to the sounds of the light.
6. Close your eyes in a natural way and turn your head towards the spot with the highest light intensity. Wave with both hands, fingers tightly pressed, in front of your eyes in opposite directions (L-hand from left to right and back; R-hand from right to left and back). Repeat but open your fingers as far as you can. Observe.
7. Stand up, close your eyes in a natural way and turn your body towards the spot with the highest light intensity. Start rotating counterclockwise -pivot around your left foot- at a slow/moderate pace. Observe. After a couple rotations gradually slow the rotation speed down, following the natural echo of your movement. Do not stop abruptly and do not start turning in the opposite direction.
- With the help of some tools
8. Take one or more mirrors. Look for the darkest place in your immediate surrounding. Use the mirror to transport the light towards this dark spot and make it lighter.
9. Take or make an object -preferably so that it can rotate- and hang it between the wall and the sun light. Make the object and observe the wall.
10. Track the Sun movement using scotch tape and a meter. Indicate every hour the position of the shade. Measure the distance between two following marks.
11. Go outside and use your meter to measure the distance from the Earth's surface to the Sun.
12. Take the train, tram or tandem on a bright day. Close your eyes in a natural way and turn your head towards the spot with the highest light intensity. Observe the back of your eyes. For this exercise it is recommended to look for a trajectory aligned with trees.
13. Take the train, tram or tandem with motorcycle helmet when the sun has just succeeded the rain. Take a seat a the sunny-side. Look through a rain drop, and another one, and… another one. Observe.
14. On a sunny day Look for a river, lake or even better a sea. Scan the water surface for the place with the highest light intensity. Focus and observe.
Note: Exercise 1-8 can be repeated with artificial light.
After the seventh SunAware exercise -hence after having seen the light, felt it, heard it, tasted and scent it, tracked it like a leaf, now thinking about it as being a nano-drop of air <.> or a hot air wave <~> in the sea of light, you have become deeply connected with the photovoltaic effect and the essence of photovoltaic cells. In fact as a human being we are to a certain extend a pv-cell as we absorb, reflect, and transform light and emit infrared radiation heat instead of electricity.
After our own observations we can take a closer -but not in depth- look at what the scientific world has to say about the light and radiation of the star called Sun.
All life on earth is ultimately solar powered and this energy is the invisible means of exchange on which all science is based. If energy is the essence of our existence than power is the extent to which useful energy is flowing. For every life form energy is needed and sufficient power to keep the flow of energy going. In the combination men, intelligence, energy, it's the source of energy, and not human inspiration that ultimately is the limiting factor for human progress. The struggle for survival in between organisms ans with others is a fight for conquering useful energy and to assure the flow of energy through these living systems. (p.51 Rifkin NL)
“If you want to understand a Microcosm, attach yourself to the Macrocosm” -Goethe
It all began 5 billion years ago when gravity pulled in a cloud of cosmic rubble, at the core getting denser and hotter, gas and dust fused together comets streaked towards the newborn sun. The same process is going on all across the sky. Our Sun is just one of a million stars. Stars born out of other stars.
“We drift through the universe…”; ”…pushed on by the solar winds”; “From planet to planet…” - Leonard Nimoy from the film Invasion Of The Body Snatchers
The hot surface of the Sun radiates electromagnetic energy that spans the entire spectrum. The intensity of the light is greatest in the visible portion of the spectrum and the warmth we feel on a sunny day is due to the absorption of the infrared radiation. That warmth is energy. Conventional solar power uses that energy to heat water. The photovoltaic (solar) cells convert electromagnetic energy directly into electrical energy. It does not have to be a hot day. All we need is light. Source: http://cs.sbcc.edu/physics/solar/sciencesegment
The electromagnetic (EM) spectrum is just a name that scientists give a bunch of types of radiation when they want to talk about them as a group. Radiation is energy that travels and spreads out as it goes– visible light that comes from a lamp in your house or radio waves that come from a radio station are two types of electromagnetic radiation. Other examples of EM radiation are microwaves, infrared and ultraviolet light, X-rays and gamma-rays. Hotter, more energetic objects and events create higher energy radiation than cool objects. Only extremely hot objects or particles moving at very high velocities can create high-energy radiation like X-rays and gamma-rays. More on EM: http://imagine.gsfc.nasa.gov/docs/science/know_l1/emspectrum.html
Taking a closer look at the nature of the energy reaching us from our biggest and oldest source of energy, there is one very important observations (and advantage): the Sun's energy is traveling towards the Earth; it comes to us.
A ray of light consists of a stream of photons -tiny packets of light energy- moving along at around 300,000km/sec. At this speed the voyage takes only 8,5 minutes. In other words, the natural light you are seeing right now has been born 8'5 minutes ago.
The total output of the Sun is 4x1026W. The intensity outside the Earth's atmosphere is 1367 W/m² The power reaching Earth is 1,78x1017W. (1,700 kWh/m²/year)
This is enough to: - provide for annual global energy consumption 10,000 times over. - produce an average 1,700 kWh of power annually on each square meter of land.
Planet earth is just at the right distance from the Sun but the greater the available solar resource at a given location the larger the quantity of electricity generated. Tropical regions offer a better resource than more temperate latitudes. The average irradiation in Europe is about 1,000 kWh per square meter, for example, compared with 1,800 kWh in the Middle East.
The Sun vibrates up and down, in and out, much like a pot of fudge boiling on the stove. When you make fudge, you can see large bubbles of chocolate covering the pan. And, in each of those big bubbles you can also see a set of tiny bubbles growing and popping with gusto. The Sun is the same. When you look at the following movies, you are viewing the large scale (big bubble) oscillations (the small ones would be too tiny to see). Images of the Sun via the SOHO satelite.
Have you ever wondered what the Sun would sound like if you could hear it? Sound won't travel through space, but with the right instrument, scientists can “hear” pulsations from the Sun. The entire Sun vibrates from a complex pattern of acoustical waves, much like a bell. If your eyes were sharp enough, you could see a bell's surface jiggle in complex patterns as the waves bounced around within it. Likewise, astronomers at Stanford University can record acoustical pressure waves in the Sun by carefully tracking movements on the Sun's surface. To do this, they use an instrument called a Michelson Doppler Imager (MDI), mounted on the SOHO spacecraft, circling the Sun 1,000,000 miles from Earth. The Sun's acoustical waves bounce from one side of the Sun to the other in about two hours, causing the Sun's surface to oscillate, or wiggle up and down. Because these sound waves travel underneath the Sun's surface, they are influenced by conditions inside the Sun. So scientists can use the oscillations to learn more about how the structure of the Sun's interior shapes its surface. The Sun's sound waves are normally at frequencies too low for the human ear to hear. To be able to hear them, the scientists sped up the waves 42,000 times – and compressed 40 days of vibrations into a few seconds. What you'll be hearing are just a few dozen of the 10 million resonances echoing inside the Sun. See: http://quake.stanford.edu/~sasha/SOUNDS/sounds.html

Solar Folklore: http://solar-center.stanford.edu/folklore/folklore.html
Photovoltaics (PV) is the direct conversion of light into electricity at the atomic level. The word refers both to the science and the technology, which are based on the photovoltaic effect: the generation of a voltage and/or a current, by absorption of light in some material or a combination of materials. Electricity that can be used for immediate power -Direct PV Systems- or delayed, with the help of storage technologies. In PV these elements are interconnected by various sciences: (quantum)physics, optics, (bio-)chemistry, engineering, materials science and micro-electronics.
The photovoltaic effect is first observed in 1839 by A.E. Becquerel, a French physicist. The first functional, intentionally made PV device is from American inventor Charles Fritts in 1883 with an efficiency of 0,1 percent. The modern era of PV starts in 1954 when Bell Labs in the USA produces a 6 percent efficient solar cell using silicon as a semiconductor. Five years later the Sputnik 3 is the first satellite using solar arrays, followed by Vanguard I for powering a small radio transistor. A major visual proof for the world that the Sun's energy can be harvested to generate electrical energy.
“Light - a mysterious element that enables people to command nature.” Sir Francis Bacon, New Atlantis (1627)
A second hallmark for PV arrives in 1973, when the global petrol crises turns the noses of petrol depending states and energy companies towards renewable energy and especially PV: US-president Carter puts PV-panels on the roof of the White House. …Only to be removed by Ronald Reagan in the slipstream of the oil crisis. Furthermore, when PV-rerearch and development face scale-up problems, budgets are drastically cut or cancelled, causing the loss of years of powerful brain power. In the eighties and nineties, with the help of consumer devices like the solar powered calculator, -wrist watch, -outdoor lighting and other novel consumer applications, Japanese, US and European companies continue to develop power modules, mainly for the building industries and for stand alone systems in remote areas.
In the 21st century, supportive government policies in many European countries and Japan, -partly driven by the Kyoto Protocol, Climate change and especially the steep rise of oil prices in 2007/08- result in a substantial increase in production. Most of the big manufacturers are either divisions or subsidiaries of large companies with diverse manufacturing interests (Sharp/BP/Shell/Kyocera). Most of the research for advanced future technologies takes place in academic and privately owned research centers. The role of PV-power in the world's overall energy system is still negligible -less than 0.5 percent- with predictions by the industries and environmental organizations that it could rise to 26% by 2040.
“The environmental impact of PV is probably lower than that of any other renewable or non-renewable electricity generating system.” - IMEC Research Center – Leuven [BE]
The strong vibrations in the rapidly expanding field of photovoltaics are increasingly being picked up by the global arts community. Since the beginning of the 21st century more artists engage and experiment with different kinds of solar cells and panels. Partly because of the technology becoming more efficient and more readily available at affordable prices. Partly because of the intrinsic qualities of the technology which when in use is silent, emission free, portable, durable and functioning as a power generator and/or a light sensing device.
But especially new designs, materials, structures and shapes have augmented the interest of creatives. The 'classic' rigid blue/grey/brown silicon-based cells are gradually joined by thin-rigid or thin-flexible organic PV cells of various colors and shapes. This means that the integration with more materials is possible, opening the way to new functions and aesthetics. These recent innovations in PV-technology are particularly fused by advances in nano-sciences, allowing PV to enter the realm of soft materials (SMPV) bringing it closer to the body, into the realm of the intimate. The energy demand of portable devices is now low enough that clothing-integrated solar cells are able to power most mobile electronics. Military textile designers are trying to overcome integration problems by developing PV-fibers that can be used for producing woven PV-textiles.
Nevertheless, the more versatile, aesthetically interesting cells like the polymer and dye sensitized solar cells are still less efficient (max 10%) and durable (<3 years) than the classic Silicon cells with efficiencies over 16% and an expected life span of 20 years and more. Also, the integration of flexible polymer (or other chemicals)-based PV with electronic consumer goods, solarbots and textiles raises environmental concerns. These are limited life span products that rapidly become a wide-spread new kind of e-waste, requiring new recycling schemes.
DIY-ing traditional silicon-PV-cells is fairly possible with extensive documentation online and with the necessary tools and materials readily available. The materials involved require a lot of 'heat, beat and treat', so it is worthwhile looking for used or recycled panels -a rapidly expanding market with as the first generation of PV-panels is reaching it's end (with the Si-cells still functioning). Or one can try to interconnect different parts of broken 'scrap' cells, requiring especially steady hands and a patient tranquil mind.
Often PV-tech is compared with the plant leaf's capacity of harvesting the Sun's energy. But there is only one type of PV-cell that mimics significantly the natural process of photosynthesis: the natural Dye Sensitized Solar Cells (nDSC). It is made of the dyes of anthocyanin or carotenoid-rich fruits like berries, currants, black beans etc., some titanium-dioxide (cf. white paint, toothpaste) some graphite or carbon and an electrolyte, all sandwiched between two tiny conductive (tin-oxide) glass plates. Easy to DIY in the kitchen with components available online, on the balcony, in the garden, the park and the street. Unsurprisingly the plants that produce the energetic nDSC-dyes are very popular amongst the bees.
“It is the role of the artist to comment on the way society is dealing with Energy.” Ai Wei Wei. “Fuck Off” exhibition, 2000 [Shanghai, CH]
One of the main challenges of the nDSSC is the liquid electrolyte, that does not exactly contribute to the already challenging life expectancy of the cells. Therefore researchers are looking for (quasi) solid state electrolytes > some papers (abstracts)
In Bartaku experiments -looking at sustainable electrolytes- human tears were extracted from a female. Due to harvesting issues the experiment could not be executed. Also, the right mood / trigger has to be applied in order to extract the right type of tears with the potentially most ionized salt complex. In the Temporary Digestopians Labs, tests will be done -if a co-creator can be motivated- to make a solid gelatin (agar agar) based electrolyte with an anti-diarrhea salt solution readily available at the local pharmacy.
Building further upon the nDSC to explore ways to express the transformation of energy from light over plants, the(ir) food; the body.

Deciding to use PV-cells for powering the electric devices of an artistic project has an impact on various levels: from the time and space of use, the choice of materials and components to the design and appearance, the relation with the user/audience and the budget. Working with PV most definitely puts the energy-aspect much higher in the project's priorities list.
Unless one does not want to make use of the fabulous opportunity to get freed from the plug, a PV-arts project might be an indoor but mainly outdoor 'autonomous' or 'stand-alone'-system. The first issue in the latter concerns the intermittent nature of the solar radiation, the ambient light intensity. Natural light is available only during the day -at varying angles according to the time of year- and strongly reduced in overcast skies. Consequently one has to decide when the energy is needed: 24hrs per day during a week in november? Or at noon only, for five minutes, every day in summer… Or maybe visiting hours have to coincide with the hours of direct Sun light.
This decision will highly determine the choice of the system design: a direct PV-stand alone system, PV-Pur Sang, with PV-cells providing electricity instantly to the Rotor, vibrator or LED-lights that respond immediately, demonstrating the flux of the qualities of light; or a stand alone system including an energy storage system for the moments when energy is needed but not guaranteed by natural light. Obviously the geographic location of the project in itself determines the amount of PV-cells needed since the solar radiation on the planet varies greatly.
“Everything is relative” - Albert Einstein
“The speed of light is not relative” - Albert Einstein
Some PV-cells perform under artificial light conditions, so the work can be placed indoors, nearby some well chosen lighting devices. The better the match between the PV-cells and the lamps' spectrum and the more optimal the distance between them, the more power is generated and the lesser cells and lamps are needed for the same output.
There are more 'tricks' to make the process the most efficient and as cost-effective as possible. One cell is connected to others to create a panel and interconnected panels constitute an array producing more volts or amps. In case the Sun is shining but not reaching the PV-cell, Archimedes' 'Heat Ray' demonstrated that mirrors can transport light for more and bigger Suns. More power is also obtained by placing a fresnel concentrating lens between the light source and a PV-cell. Or one can follow the Sun's path with the help of a solar tracker: PV-cell and panels mounted on rotating 'feet', hereby imitating the movement of heliotropic plants. In Western-Europe 30” is generally the best angle for the PV-cell's best Photon-catch.
In case there is no -or an insufficient amount of- natural light, one may consider to create a hybrid system, for example using a PV-panel and a wind turbine in wind rich areas. Still, it might be necessary to integrate an energy back up system consisting of a storage device like a battery or supercapacitor, a charge controller, a DC-DC or DC-AC inverter which is set up in between the PV-panel and the appliances. The battery can also store electrical energy in case there is production excess. But the system becomes more complex, more vulnerable, more expensive and above all, much less sustainable.
Information about plants that are interesting for the production of natural dye sensitized solar cells, including Temporary photoElectric Digestopians such as energy and efficiency values for body and solar cell; growth information etc.
The natural dye based DSC-technology expresses the strong connection between food energy (in kiloJoules) and electrical energy (power, in Watts):
1kWh equals 3600 kiloJoules OR 3,6 Joules = 1 Wh
First experiments show that the higher the kJ-value of the juice from a power plant, the more electrical energy is provided when the juice is used in a nDsc-design.
Fruits with the highest energy rates like the Chokeberries, Hippophae berries, Cranberries, Black Currants etc. are beneficial for human health as they contain high concentrations of anti-oxidants.
Update March 2011, Oaxaca (Mex): till know focus was on fruits/plants with high amounts of anthocyanin and carotenoid pigments. Research in 2011 has shown that the vast collection can be broadened up towards flora that contain betalains such as the Bougainvillea flowers (spectabilis and glabra). In Mexico the flower is used for tea as a remedy for coughs, or as part of a tea with mainly Evening Primrose (Oenothera rose Ait., hierba de golpe) and some cinnamon, used as a cure for anger, injuries from being struck, and coughs (http://www.arts.ualberta.ca/%7Etotonaco/Plants.html). (ndssc research in mexico)
The Betalain pigments are also found in prickly pear (Opuntia spp.) fruit, also known as tuna in Mexico and nochtli in the Nahuatl language. It is one of the most representative fruits in Mexican culture and has recently gained attention for its nutritional and potential technological values. Evidences of its use have existed for more than 9000 years. Opuntia plants are characterized as tolerant to varied soils, temperatures, and moisture levels. Approximately 200 species are known in the world, and Mexico possesses a great genetic variability, with a diversity of fruit pulp tonalities (red, white, and yellow) and with a wide harvesting period including fruits of early (May), intermediate (August) and late maturation (November). Opuntia plantations have previously been exploited for cochineal production. (In: J. Agric. Food Chem. 2008, 56, 5758–5764. (pdf)
Surprisingly -or yet not so- especially these plants are extremely popular amongst pollinators, esp. the bees. Therefore it is recommended to have a hive nearby the Spiradye; good for plants, biodiversity, electrical and other energies.

“The climate of the valley had such influence that, here life goes very slowly, whoever settles down in this valley in a span of fifty years, he had to slow down his pace.” Sir Edward Gait. The History of Assam (1881) - In: Brahmananda Patiri, Ananta Borah (2007).
On the map it is a straight line, from the Zoo-cum-Botanical Garden over the Ghandi Mandap to the Periferry.
Immobilized, squeezed between two other vessels, one wonders if the Periferry is actually carried by the river. In the transition time of years, period of fuzzy Suns, the Brahmaputra leaves a fertile dirt track behind in its annual retreat. He demonstrates a slow flow, disguising himself as a tamed stream with a modernist past.
Immobilized anyways due to the price of petrol, Periferry functions merely as a transition place between the South-Bank and the stand-by double-engine rescue boat as well as a chat-room for the stand-by crew. Many other boats are lining the bank, randomly, rusty, awaiting to be reshaped, re-used, or dismantled, buried.
These icons of the industrialized petrol powered era share their uncertain future with the powerful Brahmaputra, with both its water and its power that are most wanted by states, industries, people.

Companion Plants Starting point: observation on former kolchoze, aronia plantation in aizpute (latvia) Composition analysis in function of use in nDSC - based on http://www.liberherbarum.com/
* Common Valerian - Valeriaan - Valeriana officinalis
The root contains various metals: selenium, tin, calcium, magnesium, manganese, chromium, potassium, iron, zinc (all 5percent) and Sodium - Silicium
* Marigolds - Goudsbloem - Calendula officinalis > http://www.liberherbarum.com/Pn0111.HTM
Pigment: Carotenoid: 42percent
Note: considered a noxious invasive plant in many localities > (http://en.wikipedia.org/wiki/Marigold_(common) The marigolds you choose must be a scented variety for them to work. One down side is that marigolds do attract spider mites and slugs. French Marigold (T. Patula) has roots that exude a substance which spreads in their immediate vicinity killing nematodes.
* Nasturtium - Oost-Indische kers - Tropaeolum Majus One year-Creeper; native to South-America. They were brought to Spain in the 1500's and later introduced in Europe. Next to fruit trees/bush it keeps leaf lice away.
* White clover - Witte klaver - Trifolium Repens
* Blueberry - Blauwe bosbes - Vaccinium Myrtillus
Bird vetchlings - The Meadow Vetchling Milk Vetch - Wilde hokjespeul - Astragalus glycyphyllos (fam.: Leguminosae)
All species with edible seedpods can be distinguished by their fleshy round or oval seedpod that looks somewhat like a greengage. A number of species can also accumulate toxic levels of selenium when grown in soils that are relatively rich in that element (www.pfaf.org): vetch can concentrate up to 1.4% of its weight as selenium on these soils. Marco Polo (1254-1324) wrote that the animals of Turkestan behaved like the so-called 'blind staggers. The cowboys of the Wild West knew that this plant could affect their herds, and called it 'locoweed' (insane). The term usually refers also to another North American species: Oxytropis (producing another locoweed-toxin called swainsonine). In 1934 biochemist Orville Beath proved that the staggers were caused by excess selenium in the diet. When the vetch has an offensive smell, it is a sure indication that it has absorbed a high level of selenium.
Selenium is rarer than silver, and one day mineral sources of the element will be exhausted. Then we may have to harvest it by growing crops like milk vetch (3kg/acre). The current (1996 - UPDATE needed) world demand The metallic form of selenium generates an electric current when light falls on its surface, and for these electronic properties -requiring high grade selenium of 99.9% purity and accounting for a third of the production, it is used in PV-cells, light meters and photocopiers. The seconc largest user is the glass industry (Sun-ray blocking) and the third main use is to make sodium selenite for animal feeds and food supplements. Selenium is also used in metal alloys like lead plates in batteries; ac-dc rectifiers/convertors and in… anti-dandruff shampoos (Emsley, 23).
* Dandelion - Paardebloem - Taraxacum officinale
* Daucus Carota - Wilde wortel - Wild carrot
any other plant of the family can do: “The Apiaceae or Umbelliferae - family of usually aromatic plants with hollow stems, commonly known as umbellifers. Almost every widely cultivated plant of this group is a companion plant.”

About the Tufted/bird/cow vetch > cascading pea-flower shaped purple to violet flowers (purple) Tufted Vetch is widely used as a forage crop for cattle, and is beneficial to other plants because, like other leguminous plants, it enriches the soil in which it grows by its nitrogen-fixing properties. Tufted Vetch is also much appreciated by bees and butterflies as a source of nectar. The plant may also be used to curb erosion.
Just outside of the village in a westbound former part of a mighty centralized East. Over one hundred Aronia B.Melanocarpa [(Michx.)Elliot] power plants, dispersed on allotment “Number Six Four Seven, Two Zero Zero. Eight Zero Zero, Seven Two”. Originating from folded, deep brown seeds that crossed the ocean in a tiny box from West to East, before the great wars.
Mr. Vavilov meets Antoinette again. He collected seeds for his seed bank, in the North-East of America -in swamps and low woodlands from Nova Scotia to Ontario, to Florida and Michigan. The countess travels back to Europe as well, to her tiny island-cum-botanical garden on the grand mountain lake that unites and separates two countries. Then, looking over her shoulder at the black swirling ghost that returns to his chimney, he tells her hat the seeds Aronia M. ripen from October till December. - (A possible encounter on the Atlantic Ocean in 1921)
Passing the last wooden house of the village, where the road turns slightly right, the side arm on the left separates apple trees from the Aronia M. bushes. The long but narrow black coating is suffering from zigzagged scars made by ants that reclaim the land with support of sturdy spiky grasses. A blue print for land use throughout the mighty Union until it scattered into tiny new and old constellations.
For decades Aronia B.M. received the fast moving hands of schoolboys and -girls in the first weeks of September. The release after four moons from green to bold red leaves; from white flowers to a green dot of fruit, to a berry with a blue-to-black tight skin with the powerful essence that compresses it's subordinate astringent sap. Fourteen days of joyful picking nearby the apple trees, extending the summer holidays. From nine to three in rows and columns, from one side to the other and back. One basket two children, most berries are easy to reach. Honor to the boys and girls that fill the woven baskets with pure single berries -no cheating with branches or newspaper. One jar they take home, often to make wine.
'Last autumn I was thinking to plant few Aronia M.'s also in my garden. Although in childhood I hated these berries because of the strange taste. My grandmother had them and she used to tell me so often that 'They are very healthy. Try one!' - Signe Pucena – Aizpute (Latvia), 2010
The next day the village is stained with a deep dark black-blue. Them-and-us-children gathered after three, sneaked into gardens, and removed the plastic pipes that are used to span the plastic cover of the reverse-U-shaped green houses. Equipped with these blow pipes they roamed the village, trying to blow the enemy away with the 'berrybullets'. In no time the walls of the village houses were full of dark stains, including Lenin's statue.
From the basket to the shed, to the nearby juice-, jam-, syrup-, dye- and wine making factories most of the berries are moved. The allotment owner brings the left overs to the port to ship them further, in North-West direction. In exchange the North-West sends a container with most wanted warm cloths for the cold winters. The central state lottery makes the same everybody happy and the same everybody less happy, year after year.
'They just grow. There is no one who would weed it, no one to water it, to cut it. Nothing.' Agita Kemere - Aizpute (Latvia), 2010
Allotment 'Number 6 4 7 Two 0 0 8 0 0 Seven 2'. Hundreds of old sturdy wrinkly Aronia M. bushes, interconnected with their next and future generation. The echo's of the children's footsteps on the dry end-of-summer-soil interweave with the roots of Aronia M. bushes and shoots, Blueberries, Bird- and meadow vetchlings, Valerians, Parsnips and wild grasses up to a thigh-high.
'Grasses have overtaken!' - Ossi Kakko – Former A.M-Kolchoze, Aizpute (Latvia), 2010
'You can take more”, Ance Zemžāne says. 'I think nobody really needs them out here, no one is picking them any more and for that reason it is so wild. In Latvia -with this kind of heritage- it is really kind of sad. Because we have huge apple tree gardens as well here. Really really huge. And if nobody takes care of them, then there are no good fruits afterwards. Nobody picks them up. Nobody cuts the branches. And it is the same for Aronia. The grasses take over. And as you said, this is really useful stuff.'
In intermediary times Aronia M. reflects a too recent undigested past- undergoing neglect and reject by local bodies. But self-assured, with grace and with class, he reaches out for a global future that will refresh its status as a premium power plant for the body and the electric.

The 080225_pv_overview.xls is a multiple datasheet that consists of arts projects, research centers, companies and institutions engaging with photovoltaics. It also contains a section with DIY resources, pv-events and educational offers and media focusing on photovoltaics. As this research is addressed to the creative community special attention has been paid to the aesthetics of the technologies that are listed. The period in which the data are collected is August 2007-December 27, 2007. It is not an exhaustive overview, but merely an inventory of virtual and reel encounters on the research path. At this moment the data are presented in a rather vernacular and not-so user-friendly way. Quickest way to find what you need is searching via key word-search (<ctrl> <f>) and by sorting (<Data> <Sort>).
Coinciding with this research project, the pv-field started vibrating and expanding more than ever before mainly due to the drastic rise of oil prices (a situation that happened before during the oil crisis in the 1970ies, but this time the investments will not be cut back or stopped as the oil peak (see glossary) is arriving soon). Almost every week new technologies, companies, mergers & take-overs, projects, experiments and PV-media emerge. As a consequence this incomplete overview is a living being that needs to be nurtured continuously in order to let it undergo its ever changing mood.

With special interest in scientific tropes and 'hyper-wound realities', Bartaku interweaves various media, methods and technologies. His work echoes former praxis as a drummer, social scientist and aimless wanderer. In 2007 he initiated “PhoEf: The Undisclosed Poésis of the Photovoltaic Effect”, an exploration of the micro and macro-realms of Photovoltaics – the science/technology based on the conversion of light into electrical energy – at the interstices of arts, science and technology.
