Objectives
  • An article on the nanohouse project was
    published on this web site (www.nanovidensbank.dk)
    , a co-operation between the iNano Centre at the
    University of Aarhus and Innovation Lab, also in
    Aarhus
  • Objective To use the nanohouse example to
    discuss several environmental consequences of the
    invisible aspects of some nanotech applications.
  • At first glance, this may seem paradoxical...
  • Synthesizing the main features of most
    nanohouses (See for instance Green Technology
    Forum http//www.greentechforum.net/greenbuild/
    ).

5
Materials
  • Insulation glass, coatings , aerogel, etc.
  • Coatings self-cleaning, anti-stain,
    depolluting, scratch-resistant, anti-fogging,
    anti-corrosion, anti-microbial, UV protection.
  • Other materials plastic polymer,
    nano-adhesives, optical fibers, new structural
    materials, anti-bacterial, etc.

6
Sensors
  • Alarms (break-ins, gas leaks, fire detection,
    etc.)
  • To control the physical conditions inside the
    house (temperature, humidity, lighting, airflow,
    air purification) and other activities (cleaning,
    food, etc.)

7
Other equipment
  • Energy storage (solar panels)
  • Water and air purification systems
  • Hardware (consumer electronic products such as
    TV, stereo, kitchen appliances, communication
    devices, etc.)

8
Nanotech invisibility comes from
  • the extraordinarily small scale at which this
    work takes place (nanoscale),
  • the difficulty in understanding the scientific
    theories on which they are based,
  • modern sciences emphasis on mathematics
    (abstraction disassociated from the every-day
    world, modelization, virtualization) (Frodeman
    2006),
  • the lack of effort put into communication by
    many experts in this field,
  • the secrecy of some areas of research (military,
    national security, private sector),
  • the abuse of hyperbolic rhetoric used in favour
    and against nanotechnology (Berube, 2006)
  • the lack of star products in the market,
  • technological somnambulism. Most of the time
    citizens can be compared to sleepwalkers who are
    unaware of how technology mediates their lives
    (Winner 1986),
  • etc.

9
Some clarification
  • A very heterogeneous list of meanings that
    relates to some nanotech applications more than
    to others.
  • The invisibility of nanotechnology, more that an
    obscure metaphor.
  • First, a brief conceptual clarification the
    opposite of visible is invisible the opposite of
    transparent is opaque. However, when used to
    express values, these concepts are ambiguous.
  • Something opaque has a visible surface that we
    are unable to see through so, although we can
    see the opaque object or process it is
    difficult (if not impossible) to understand and
    control its inner workings.
  • On the other hand, a transparent object is
    invisible (or almost invisible), but we use the
    word transparent to express a positive
    appreciation of a political decision-making
    process.

10
Opaque and transparent objects
  • The opaque (watch) The transparent object is here


Dont you see it?
11
What we are seeking
  • Visibility of what lies underneath, and...
  • ... transparency of what lies on the surface.
  • In other words, nanotech should be visible and
    transparent at the same time.

12
Meanings of transparent
An epistemic state E is transparent to a subject
S if and only if when S is in state E, S can know
that S is in state E (ex. pain)
13
Literally becoming invisible
  • Nanosensors in the soil, the air and even the
    human body employed to detect dangerous
    substances, control communications or fight
    internal and alien enemies. Other invisible
    devices invisible airplanes and computer systems
    that monitor communications (not specifically
    nanotechnological).
  • Nanotechnological devices are predicted to be
    extremely minute, undetectable, and powerful.
  • Invisibility directly linked to secrecy.
  • An invisible suit for soldiers?

14
An invisible environment
  • The main problem of some emerging technologies
    (such as ambient intelligence, distributed
    computing, GMOs and some kinds of nanotechnology)
    is that they no longer signify mastery of nature
    but take on the character of nature itself
    (Alfred Nordmann 2005).
  • These naturalized technologies create a
    quasi-natural environment in which we live,
    although we are unaware of how they work.
  • They are transparent in a negative sense we are
    unable to perceive them with our senses or
    intellect. In ethical and political terms they
    are opaque.

15
What is wrong with an invisible technology?
  • The more opaque a technology is, the more
    difficult it is to control democratically (e.g.
    civilian and military uses of nuclear power,
    information technologies used for national
    security).
  • Moreover, this invisibility is often sought
    after by technology promoters, e.g. the
    opposition to tracking and labelling of GMOs in
    the market.
  • If nanotech remains invisible the public may
    become hostile to applications that become
    visible in an inappropriate manner.
  • On the other hand, because the social and
    environmental impact of many nanotech
    applications would unquestionably be highly
    visible and significant, most critics worry that
    they might be undemocratically imposed without
    public debate or transparent decision making.

16
Making nanotech visible
  • A paradox the fact that nanotechnological
    developments might increase technical agency
    throughout the world could provoke an unethical
    decrease in individual and collective agency.
  • Democratic mastery of these new technologies
    implies an adequate understanding of its more
    relevant functional attributes .
  • In order to obtain this understanding and
    democratic control, nanotechnologies need a
    proper cultural adaptation or social
    representation, the construction of a social
    imaginary that is not imposed, but rather based
    on public, active participation and
    responsibility.
  • Formulas that can be implemented to make
    nanotechnologies visible to the social sphere in
    a democratic fashion (public participation
    methods and community-based research).
  • Another approach using representational chains
    to make nanotechnology visible.

17
The nanohouse as representation
  • Are all aspects of the technology used to create
    the nanohouse visible when we see the finished
    product?
  • Does the nanohouse adequately represent how
    nanotechnology is used in its design,
    construction and operation?
  • Benefits, drawbacks and ethical dilemmas that
    could arise during the production process and
    life cycle of the nanomaterials (design,
    production, transport, storage, usage and
    disposal).
  • What about the quality of the representations
    offered by the nanohouse?
  • Three different (although interconnected) ways
    of representing 1. through the macroscopic
    effects of nanotech
  • 2. through the technical code inscribed in its
    design
  • 3. as a demonstration of the possibilities of
    nanotech.

18
Representation through macroscopic effects
  • A crucial element in the publics perception,
    understanding and eventual acceptance of the
    technology at stake
  • Effects invisible but tangible.
  • Examples rust-resistant paint, glass that
    darkens as sunlight increases, nanosensors which
    monitor and regulate the physical conditions
    inside and outside the house, etc.
  • Although some nanotech materials and devices are
    already being incorporated into every day
    products, consumers are not conscious of this
    unless the company that is selling them markets
    the nanotech components as an added value.
  • From a democratic point of view, the fact that
    companies are eager to reveal the nanotech
    features of their products is beneficial.
  • However, companies could simply make no
    reference to the worrisome aspects of their
    products.

19
Looking through the window
  • When owners of nanohouses look through their
    transparent windows, they do not see the
    invisible system that regulates the amount of
    light that can pass through the glass.
  • When the glass darkens, when it becomes opaque,
    it literally and metaphorically hides the
    environment outside the house.

20
Representing through scripts
  • The nanohouse also represents nanotechnology
    through the script (actor-network theory) or
    technical code (Feenberg) inscribed in its
    design.
  • This script acts as the vision of a nascent
    technology. It defines the problem to solve,
    frames it, assigns roles to and relationships
    between objects and people, it establishes the
    configuration of the technologys entire network.
  • The script is crucial in distributing agency
    between different actors involved.
  • The technical code holds the technical
    specifications of the technology. It provides us
    with the basic definition of a technical object
    or system. These features are specified in a way
    that reflects the significant social values at
    stake, the social meaning, as they are assumed
    by the promoters of the technology.

21
How the technical code is made visible
  • The script-technical code is usually visible to
    a few in manuals and other technical literature -
    even in the statements made by its creators.
  • It remains invisible to most people, because
    the values it incorporates are culturally rooted,
    or they are (for different reasons) not a subject
    of discussion.
  • It may become highly visible through
    controversy, be it technical, political or
    otherwise.
  • The nanohouse can play a significant role as a
    manifestation of what a house should be in the
    future as a prototype (or a sort of
    kuhnianexemplar) for further development in
    this field.

22
Definition of the objective
  • To achieve an adequate level of comfort and
    protection for users and sustainability through
    exclusively technological means.
  • Comfort is defined in terms of demanding Western
    standards.
  • Sustainability is understood mainly in terms of
    energy efficiency.
  • The most natural" or traditional ways of
    achieving both objectives  (comfort and
    sustainability) are discarded for example, a
    bioclimatic architectural design inspired by the
    popular architectural legacy. 
  • The larger environment where the nanohouse is
    built and the repercussions of the production of
    the material and equipment needed for its
    construction (the life cycle of the product) are
    not fully considered.

23
Distribution of agency
  • Devices are assigned an active and friendly role
    (they take care of everything)
  • Users (of the house) are assigned a passive
    role as the beneficiaries of the technological
    system.
  • The natural environment appears either as a
    supply of resources  (e.g. sunlight converted
    into energy) or as a hostile agent from which
    users must be protected.

24
Meaning or interpretation conveyed
  • Thanks to nanotechnology we can live as well or
    better than we did in houses in the past or
    present.
  • By leaving experts to resolve problems, we can
    remain unconcerned users, without changing our
    habits or even consciously exerting control over
    our environment.
  • Nanotechnology can solve all our problems,
    including problems that it itself generates.
  • The nanohouse is the best way to achieve
    sustainable housing.

25
Demonstrative representation
  • The nanohouse is intended to play a significant
    role as a demonstrator of the potential of
    nanotechnological applications to build smart
    houses.
  • This role can be accomplished directly by
    letting people experience living in a house
    that uses nanotechnology, or indirectly, through
    media coverage
  • illustrations,
  • articles,
  • tv broadcasts,
  • etc.

26
Some media headlines
  • Nanohouse brings Nanotechnology home
  • (http//www.csiro.au/files/mediarelease/mr2003/Prn
    anohouse.htm)
  • Big technology is shrinking our world
  • (www.infolink.com.au/articles/AB/0C03C0AB.aspx)
  • The smart home
  • (www.innovationlab.dk/sw19071.asp?usepftrue)

27
Epistemological and political representation
  • The different ways that the nanohouse serves as
    representation have something in common the
    house acts as a sort of mediator or
    representative between the public and its
    promoters.
  • Scientists, engineers (and architects) represent
    nanoparticles and nanostructures on the human
    level. They enter the political arena endowed
    with an epistemological power that is transformed
    into political power, into agency, into the
    ability to carry out actions.
  • Representational networks extend from the
    laboratory to the social sphere in a
    "self-vindicating" dynamic (Hacking 1983) where
    epistemological and political representations
    reinforce each other reciprocally.
  • Networks of human or non-human actors aspire to
    control every facet of the representation through
    a chain of translations or mediations (Latour
    2005).

28
Conveyed imaginary Nanomaterials are smart,
natural ones are dumb
  • Smart materials have almost endless potential
    they can change in response to their surroundings
    in ways that natural (dumb materials) dont. Some
    materials could have tiny computers embedded in
    them which can send signals - like tyres that
    tell your car when the tread is wearing unevenly,
    or paint that alerts your house of a gas leak or
    an electrical fault. Really smart materials could
    change colour on command, or generate electricity
    during the day and make it available at night.
    Imagine coatings that refuse to become dirty, and
    heal themselves when damaged!

29
Which representation of the nanohouse?
  • Promoting an imaginary based on technical
    control and energy efficiency,
  • Omitting less savoury aspects of the
    technological system in a global world (e.g. the
    asymmetrical distribution of costs and benefits).
  • In order to make a technology our own and
    integrate it harmoniously into our lives we must
    first use it so that we can comprehend it,
    assimilate it and elaborate a sufficiently
    coherent and rich imaginary.
  • That is, symbolic appropriation or cultural
    appropriation (Andrew Jamison).

30
Kinds of representation
  • ? Symbolic appropriation ?
  • Visual Epistemological-Technical Social
    Political
  •  
  • ? Imposition

31
Alternative representation
  • Citizens need to have access to the technical
    code of the nanohouse in order to decide whether
    it is a proper solution to sustainable housing.
  • This process has to do with the quality of both
    epistemological and political representations.
  • Epistemologically, the chains of representations
    that connect laboratory research with the design
    of nanohouse components should be explicit and
    clearly communicated and debated.
  • Politically, citizens should have proper
    representation in the decision-making process.
  • The technical code translates political
    decisions into technical and epistemological
    constraints. This translation movement should be
    made visible, that is, it should be unmasked,
    exposed and criticized (Feenberg 1999).

34
Some issues to be debated
  • The potential risks to the environment and human
    beings that can arise during the entire life
    cycle of nanotech housing technology, such as
    toxicity and ecotoxicity.
  • Whether nanotechnology can be a universal
    solution to environmental problems (the gaps in
    theoretical as well at applied levels of nanotech
    for sustainability).
  • The wider environmental, social, economic and
    ethical problems of extensively developing
    nanohouses.
  • Whether substantial changes should be promoted
    (together with feasible technical solutions) in
    attitudes towards consumption, traditional
    solutions for housing, distribution of costs and
    benefits on a global scale, respect for nature,
    etc.

35
Looking for transparency
  • Principle V. Transparency. Assessment and
    oversight of nanomaterials requires mechanisms
    ensuring transparency, including labelling of
    consumer products that contain nanomaterials,
    installing workplace right to know laws and
    protective measures, and developing a publicly
    accessible inventory of health and safety
    information.
  • Various signatories, Declaration, Principles for
    the Oversight of Nanotechnologies and
    Nanomaterials, 2007.

36
Conclusion
  • In an environment where GMOs are invisibly
    altering living beings, where 90 percent of
    existent species are invisible and therefore more
    easily extinguished by human activity, it is
    crucial not to foster invisibility or
    obscurantism, be it technical or other.
