Our goal is to provide vegetable factories enabling cultivation in all conditions, whether in a desert, frigid clime or the middle of the city," said Tokitaro Hoshijima, project director, Project PV at Mitsubishi Chemical Corp of Japan. The company plans to launch its vegetable factory business, including a combination of solar cells and light-emitting diodes (LED), at around the end of 2009.
The firm's vegetable factory will shut out the outside world and totally control the interior environment, including temperature, humidity, CO2 concentration, nutrients and illumination. Running costs will be minimized through a combination of solar cells and LEDs. Mitsubishi Chemical has entered the vegetable cultivation field through a tie-up with Fairy Angel Inc of Japan, already experienced in commercial vegetable factories, to cooperatively develop a new type of vegetable factory integrating solar cells and LEDs. An experimental plant will be constructed in part of Fairy Angel's newest plant, scheduled to come online in August 2008, and used from this fall to optimize vegetable growth parameters for the solar cell/LED design.
Zero Electricity Costs
Vegetable factories are hot these days: consumer interest in food safety is surging, and vegetables cultivated in cleanroom factories are becoming increasingly popular. For producers, foodstuff-related firms and other parties in the field, vegetable factories mean planned production, unaffected by changes in the season, weather, or other factors.
These vegetable factories face a major problem, though, in the high cost of electricity for lighting, air conditioning and other uses, which accounts for about 30% of total running cost. Mitsubishi Chemical hopes to cut electricity cost for vegetable plants to zero.
According to a source at Mitsubishi Chemical, switching from florescent lights to LEDs will cut power consumption far enough to make it possible to use solar cells to supply the load. Engineers use red and blue LEDs, which cover the absorption peaks of chlorophyll, to achieve more efficient illumination than that available from red-deficient florescent tubes. The intermittent illumination that LEDs excel at is ample for photosynthesis, and the end result is a major reduction in power consumption. Engineers believe that illumination on a 200us cycle is sufficient for cultivation.
Using solar cells also means a higher initial cost, though. Mitsubishi Chemical hopes to resolve this problem by using organic solar cells, costing a fraction of what Si-based solar cells cost. The firm plans to resolve fundamental obstacles to volume production by 2015, stating that organic solar cells would cut cumulative costs (power source and lighting-related expense) to the same level as florescent lamps running off the commercial grid in about seven years, and end up about 30% lower in a decade (Fig 1). Si-based solar cells will be used to construct a factory with zero CO2 emissions in operation, and once organic solar cells enter volume production they will be used to construct a vegetable factory.

Nokia is experimenting with using GPS-enabled mobile phones to collect traffic information collaboratively, in an effort to reduce traffic congestion:
Nokia Research is offering free real time traffic information to users with GPS-enabled mobile devices.
The Mobile Millenium project, which Nokia is developing along with researchers from the University of California at Berkeley, will be available to people as part of a pilot project aimed at collecting and studying traffic data. Currently it covers the greater Bay Area in California; users can download the software for free starting midnight Monday.
“Traffic is very common problem anywhere in the world and it affects issues such as energy consumption and carbon footprint,” says Henry Tirri, vice president and head of Nokia Research Center. “We want to show what you can do with pervasive sensing of the environment through millions of phones that people carry every day.”
Nokia says it believes a community of users with GPS-equipped mobile devices can help reduce traffic by enabling drivers to make better decisions.

Ou quand les millions des téléphones portables se transformeront en autant de senseurs pour capter l'environnement, mais aussi les mouvements des personnes, etc.

The idea that architecture might have medical effects on the people who experience it was the premise of a project by Marina Nicollier produced this year at Rice University.
In the project's accompanying documentation, Nicollier writes that we must learn "to create spaces that provide, through their experience and material substance, enough variability in environmental effects that individual differences in reception and response can be studied and used as a part of curative regimes."
In other words, the sensorial experience of architecture could play a role in healing – or, as Nicollier explains, "spaces themselves should act as experiential platforms that provide a broader spectrum of environmental qualities, so that we may better understand their effects on our psychology – and ultimately, on our physiology."
[Image: From "Change of Heart" by Marina Nicollier].
From the project description:
The human body responds to its spatial and environmental surroundings in very subtle ways. Our most basic reactions to our environment can be read, essentially, in our vital signs; yet as many of these phenomena are subtle enough to be easily overlooked without some sort of monitoring device, they have been too often dismissed as fleeting emotional and sensorial effects that have little impact on our physiological system as a whole. These qualities can do much more. They can act as an architectural base for a very important body of research, expanding beyond the limited range of possibilities imposed on them by existing models of medical environments.
To perform a test-run for these propositions, Nicollier has designed a "cardiology research facility adjacent to two major medical institutions in Mexico City."
You would wander through the building, hooked up to electrocardiographs, every flutter of heart valve and sweat gland monitored by doctors from afar.
[Image: From "Change of Heart" by Marina Nicollier].
I was on Nicollier's final thesis review the other week, where I joked that the project was like a visual combination of Barbarella and Constant's New Babylon, by way of A Clockwork Orange – an immensely positive combination, I might add.
But that same impression strikes me today: that this is the kind of project Constant might have designed had he been more interested in the avant-garde spatial application of cardiac self-analysis.
It is the megastructure as medical cocoon, architecture designed to stimulate the human nervous system.
[Image: From "Change of Heart" by Marina Nicollier; think of it as a Foucauldian application of Winston Churchill's famous phrase, that "We shape our buildings, and afterwards our buildings shape us." Only here, those buildings cause heart palpitations].
Nicollier's cardiology research lab "relies on an experience-based design generated on a series of gradient intensities," she writes.
She then contrasts this brilliantly with the design of modernist sanitariums, highlighting what might be called the medical origin of modern architecture:
Popular ideas about what constitutes a healthy environment gave rise to many of the components that became the formal trademarks of modernism – the flat roof was devised as a means to provide additional sunning surfaces for tubercular patients; while the deep verandas, wide private balconies, and covered corridors served as organizational tools to isolate contagious patients from the general staff.
Indeed:
Visits to these establishments were prescribed, as were the conditions and durations of the exposures themselves. Today, of course, there is ongoing research to determine how and to what extent environmental factors such as temperature, natural and artificial light, and sound affect our health, and despite there having been some interesting conclusions, it is still an area of research that requires more investigation and exploratory trials.
Then, however, in the 1950s it was discovered that tuberculosis was only treatable through the use of antibiotics, and so architectural modernism – with its wide verandahs and flat roofs – lost its medical justification, so to speak. It became just another style to be mined for a new pastiche of superficial quirks and regional variations.

Even the siting of the project, in Mexico City, plays on this development. Early modern sanitariums and "health resorts," Nicollier writes, were designed with "specific needs regarding their site."
Their regime of exposure to light, temperature, and clean air limited called for very particular climatic conditions falling within acceptable ranges. This is why the vast majority of these facilities were built in remote, rather idyllic locations near the coast or tucked away in alpine forests, away from any urban centers, which were considered to be too dense and dirty to be of any use for a treatment regime.
To wit, Thomas Mann's Magic Mountain.
Locating a facility like this, then, in Mexico City, a notoriously polluted megalopolis, is to suggest that architecture can counteract – that is, influentially avoid negation by – even the most invasive and unnatural of contexts. The building "supplements the environmental qualities of the city, incorporating them into its intensity gradients," in Nicollier's words.
[Images: From "Change of Heart" by Marina Nicollier].
But I find it almost overwhelmingly interesting to think that controlled exposure to a certain piece of architecture could actually be prescribed as a medical treatment. Viewed this way, the immersive experience of a well-designed space could actually stimulate one toward otherwise unknown medical highs and lows.
A building becomes almost pharmaceutical – or narcotic – in its level of influence over those who use it.
Could a building even become addictive?, one might ask. Could you experience something like withdrawal after going too long without experiencing it?
Might you literally someday receive a prescription from a doctor telling you to visit a certain building for twenty minutes, because the phenomenological impact of its vaulted galleries might cure you of whatever – kidney stones, anemia, or even manic-depression. Male pattern baldness. Sexual frigidity.
Space is the treatment for the things that harm you.
[Image: From "Change of Heart" by Marina Nicollier].
During Nicollier's thesis review, we discussed whether it might be possible for her building to act as a template or prototype for other such projects elsewhere. That is, could you produce a kind of spatial franchise in which certain combinations of color, materiality, texture, sequence, and even scent would be put to use for medical purposes? The light, sound, and temperature of the building would thus act as a general format, available to other designers in utterly dissimilar circumstances.
Perhaps it'd even be subject to regulation by the FDA and reproduced as a generic in Canada.

The sections, meanwhile, are beautiful in their own way –

Personal comment:
Je ne serais pas étonné d'apprendre que Marina Nicollier soit passée par un atelier de Philippe Rahm à l'EPFL, à Mendrisio ou à la AA, car le projet ressemble beaucoup à ce que j'ai pu voir en critique dans son atelier. Reste que le projet est intéressant et renvoie dans le fond à des architectures de type sanatorium!
