A summary of these ideas can be found in 1) What Drives Exponential Improvements? California Management Review, Spring 20132) Technology Change and the Rise of New Industries, Stanford University Press, 20133) Exponential Change: What drives it? What does it tell us about the future? http://www.amazon.com/Exponential-Change-drives-

Objective of this Session
Understanding the mechanisms of improvements can help us understand when a new technology might become economically feasible
For economic feasibility, we can also use the term value proposition◦When does a new technology provide a superior
value proposition to some set (or an increasing number) of users
New Technologies Diffuse….Because they offer a superior value
proposition to some set of users (when compared to existing technologies)
Larger value propositions (e.g., profitability) lead to faster rates of diffusion
Benefits from the value proposition include◦superior performance in one or more dimensions◦superior features, lower price
When might improvements in cost or performance enable a new technology to offer a superior value proposition?
OutlineValue Proposition and economic feasibilityHow do Improvements in Cost and
Performance Occur, i.e., what are the mechanisms? ◦Creating materials that better exploit physical
phenomena◦Geometrical scaling◦Some technologies directly experience
improvements through these two mechanisms while others indirectly experience them through improvements in specific “components”

How do improvements occur?A Key Aspect of any Technology, what some call a
Technology Paradigm
1) technology’s basic concepts or principles and tradeoffs that are defined by concepts or principles
2) directions of advance within these tradeoffs where these advances are defined by a technological trajectory(s); ◦What drives improvements in cost and performance?
3) potential limits to these trajectories and their paradigms
4) roles of components and scientific knowledge in these limits
Focusing on ImprovementsCreating materials (and their associated
processes) that better exploit physical phenomena
Geometrical scaling◦Increases in scale: e.g., larger production equipment,
engines, oil tankers◦Reductions in scale: e.g., integrated circuits (ICs),
magnetic storage, MEMS, bio-electronic ICsSome technologies directly experience
improvements while others indirectly experience them through improvements in “components” ◦Computers and other electronic systems◦Telecommunication systems
Items 1, 2, 3: involve lighting
Other Evidence for Lighting Full quote for LEDs from Azevedo et al, 2009: “In 1962, Holonyak,
while with General Electric’s Solid- State Device Research Laboratory, made a red emitting GaAsP inorganic LED [27]. The output was very low (about 0.1 lm/W), corresponding to an efficiency of 0.05% [27]. Changing materials (toAlGaAs/GaAs) and incorporating quantum wells, by 1980, the efficacy of his red LED had grown to 2 lm/W, about the same as the first filament light bulb invented by Thomas Edison in 1879. An output of 10 lm/W was achieved in 1990, and a red emitting light AllnGaP/GaP-based LED reached an output of 100 lm/W in 2000 [27]. In 1993, Nakamura demonstrated InGaN blue LEDs [28]. By adding additional indium, he then produced green LEDs and, by adding a layer of yellow phosphor on top of the blue LED, he was able to produce the first white LED. By 1996, Nichia developed the first white LED based on a blue monochromatic light and a YAG down-converter.”
Quote for Organic LEDs: “The next few years should see major advances in this area, and the availability of a much wider array of durable materials and processes than currently exist for the device designer.” (Sheats et al, 1996).

Different Classes of Materials were found for Many Technologies
New Processes are Often Key Part of Creating New Materials
New materials usually involve new processes◦Semiconductor ICs, MEMS, bio-electronic ICs,
nanotechnology, lighting, displays, batteries◦We will talk about new materials and
processes for them throughout this module
Incremental Improvements to these processes are also important
Learning curve emphasizes small changes to the processes, which do play a role in achieving improvements
But small changes to the processes can’t explain exponential improvements in performance
Without new materials and most importantly new classes of materials, exponential improvements would not be achieved
For these and other TechnologiesAt what rate is a technology being improved along the
relevant dimensions of performance or cost?When might these improvements lead to a superior value
proposition for ◦some set of users?◦most users?
What are the potential/limits for improvements: can new materials that better exploit a specific physical phenomena still be found?
Are there complementary technologies that are needed for these improvements?
As an aside, what are the policies or strategies that will ◦promote these improvements?◦help us find and exploit these markets?
Must Also be Concerned with Abundance, Since Impacts Cost
OutlineValue Proposition and economic feasibilityHow do Improvements in Cost and
Performance Occur, i.e., what are the mechanisms? ◦Creating materials that better exploit physical
phenomena◦Geometrical scaling◦Some technologies directly experience
improvements through these two mechanisms while others indirectly experience them through improvements in specific “components”
Geometric Scaling (1)Definition
◦refers to relationship between geometry of technology, the scale of it, and the physical laws that govern it
◦“scale effects are permanently embedded in the geometry and the physical nature of the world in which we live” (Lipsey et al, 2005)
Studied by some engineers (and biologists), but only within their discipline◦chemical engineers: chemical plants (many references)◦mechanical engineers: engines, tankers, aircraft (fewer) ◦electrical engineers: ICs, magnetic, optical storage (many)
But very few analyses◦For engineering in general◦By management professors ◦By economists
Geometric Scaling (2)For technologies that benefit from smaller scale, the
benefits can be particularly large, since◦costs of material, equipment, factory, transportation typically
fall over long term as size is reduced◦performance of only some technologies benefit from small size◦smaller transistors or magnetic regions can increase speed,
functionality; reduce power consumption, size of final productFor technologies that benefit from larger scale
◦output is roughly proportional to one dimension (e.g., length cubed or volume) more than is the costs (e.g., length squared or area) thus causing output to rise faster than do costs, as the scale of technology is increased
◦Also true with biology examples (think of thin vs. heavy people)
What do the dimensions of these creatureshave to do with scaling?
Enough biology (Bonner, J. 2006, Why Size Matters: From Bacteria to Blue Whales, Princeton University Press. Schmidt-Nielsen K 1984. Scaling: Why is Animal Size so Important?)
Let’s Move to technologies and ones that benefit from reductions in scale

But this wasn’t simple. Reducing the scale of features on a transistor required better processes and new equipment for these processes
Often this equipment was developed in laboratories and often the laboratories of suppliers
While some might call this learning…….. It is a special form of learning that goes beyond tinkering with existing processes
Christensen’s theory of disruptive innovation also implies that performance improvements automatically emerge once a low-end innovation has been found
Christensen’s interpretation1) Low-end innovations emerge and are
used by a new set of customers; 2) Incumbents ignore them because they
do not meet needs of their customers;
3) Increases in demand lead to improvements in them;
4) Eventually low-end innovation displaces dominant technology and thus incumbents fail in both new and established market
My Questions1) How do firms increase the capacity of
disk drives?2) What drove and in particular which
markets for disk drives drove these improvements?
3) Are these large (or small) improvements in capacity?4) How many other products experience such large improvements?

But the creation of new materials also help………

Other Technologies that Benefit from Reductions in Scale (1)
MEMS (micro-electronic mechanical systems) for many applications◦Gyroscopes, resonators ◦micro-mirrors, photonics◦ink jet nozzles for printers, micro-gas analyzers
Bio-electronic ICs (MEMS with micro-fluidic channels) for many applications◦Point-of-care diagnostics ◦Drug delivery◦chips embedded in clothing, body, etc.
DNA sequencing
Other Technologies that Benefit from Reductions in Scale (2)
Nano-technology for many applications ◦E.g., membranes, nano-particles, nano-fibers,
graphene, carbon nanotubes: e.g., smaller size leads to higher surface area-to volume ratios
◦Also other phenomena that benefit from smaller scale (Richard Feynman first noted these things in the 1950s: There is a lot of room at the bottom)
These technologies benefit from reductions in scale because certain phenomena occur at small scale
These applications are covered in detail in subsequent sessions
OutlineValue Proposition and economic feasibilityHow do Improvements in Cost and
Performance Occur?◦Creating materials that better exploit……◦Geometrical scaling
Increases in scale◦ larger production equipment: more benefits for continuous
flow, furnaces/smelters, displays/solar panels than with discrete parts (e.g., automobiles)
◦Engines and transportation equipment: large benefits
◦Some technologies directly experience improvements through these two mechanisms…
Scaling in Production Equipment
We all know about economies of scale◦ But some products benefit from economies of scale more
than do others◦ Why? Some products benefit from increases in scale of
production equipment more than do othersLargest benefits for
◦ chemicals, other continuous flow equipment◦ furnaces and smelters
Smaller benefits for discrete parts equipmentBut also large benefits for
◦ Semiconductor wafers, displays, solar cells, graphene, carbon nanotubes, and their manufacturing equipment,
Production of Liquids or Gasesin a Continuous Flow Factory
Many products are liquids or gases or are in liquid or gaseous state during production
Processes such as mixing, separating, heating, cooling, filtering, settling, extracting, distilling, drying are done in pipes and reaction vessels
Pipes◦Cost is function of surface area (or radius)◦Output is function of volume (or radius squared)
Reaction vessels ◦Cost is function of surface area (or radius squared)◦Output is function of volume (radius cubed)
Results of ScalingEmpirical analyses have found that equipment costs
only rise about 2/3 for each doubling of equipment capacity
Large continuous flow manufacturing plants have been constructed
For example, ◦Ethylene was produced in plants with less than 10,000 tons
of capacity in 1942◦By 1968, it was being produced in factories with a capacity
of 500,000 tons per year◦Capital costs per unit dropped 25% during these years
Barriers to Increases in Scale
Scaling only works if thickness of pipes and reaction vessels do not have to be increased◦this requires better materials◦Without these better materials, benefits from scaling
would not occurWeight increases as the cube of a dimension
while strength only increases as the square of a dimension
Thus, limits to size of continuous flow plants begin to emerge
Similar arguments apply to many of the other examples described this semester
OutlineValue Proposition and economic feasibilityExisting theories of technological changeWhat Drives Improvements?

◦Some technologies directly experience improvements through these two mechanisms….
Furnaces and SmeltersUsed to process metals such as steel, copper, and
aluminumThis processing requires large amounts of fuel and
oxygenBenefits to scaling; similar to but perhaps smaller
than continuous flow production◦Cost of constructing furnace and heat loss from furnace or
smelter is function of area ◦Output is function of volume
For example, ◦Steel factories had a capacity of a single ton per day in 1700
and 10,000 tons per day by 1990◦Cost of crude steel dropped between 80 and 90 percent from
the early 1860s to the mid-1890s (following emergence of Bessemer process)
From small scale (2000 years ago) to big scale (20th century)
Example of Even Bigger Furnaces: Modern Steel Mill
Increasing Scale of Blast Furnaces: Output Rose with Volume while Capital Costs and Heat Loss Rose with Surface Area
Vaclav Smil, Creating the Twentieth Century: Technical Innovations of 1867-1914 and Their Lasting Impact
Complementary Technologies Often are Needed to Benefit from “Scaling”Size of a furnace or smelter is limited by
need to deliver smooth flow of air to all of molten metal
Hand- and animal-driven bellows could only deliver a limited flow of air
Water-driven bellows and steam-driven ones allowed air to be injected with more force so that larger furnaces could be built
Large steam engines further increased the potential scale of furnaces/smelters
Bellows For Fireplace: Much Bigger Ones are Needed for Blast Furnaces
Increasing Scale of Aluminum “Cells:” Output Rose with Volume while Capital Costs and Heat Loss Rose with Surface Area
Inflation adjusted prices/costs also fell: prices fell from $721/ton in 1900 to $65.6/ton in 2000 ($1640 in 2000 prices)

For Your ProjectsSome groups will analyze new materials that will
probably benefit from increases in scaleTry to use the previous slides to estimate the
benefits from increasing the scale of production equipment
When you find data that says a technology benefits from increases in temperature or pressure, it is likely that increases in temperature or pressure require increases in scale
Academic papers might not tell you there are benefits from increases in scale◦They will focus on design tradeoffs◦You must read between the lines

Discrete Parts ProductionMuch lower benefits from increases in scale
of discrete parts production equipment than from equipment used to produce◦liquids, gases (continuous flow production), ◦metals (furnaces and smelters)
Larger machines can load, cut, bore, unload, and assemble parts somewhat faster than can smaller machines
Benefits of scaling in discrete parts production also depends on types of product. More benefits for automobiles than for apparel or shoes
Impact of Scaling in Production Equipment on Price of AutosIn 1909: standard 4-seat Model T cost $850
(equivalent to $20,091 in 2011)The price dropped
◦ to $440 in 1915 (equivalent to $9,237 in 2011)◦ $290 in 1920s (equivalent to $3,191 in 2011 or similar to
cheapest Tata-Nano) mostly because of substituting equipment for labor
Since then the scale of automobile factories has been reduced
Today few auto factories produce more than 100,000 autos/year
Diminishing returns to scale emerged many years ago

Increases in Scale of IC Wafers, LCD Substrates, Solar Substrates (1)
Equipment costs per area of output fall as size of equipment is increased, similar to chemical plants◦Cost is function of surface area (or radius squared)◦Output is function of volume (radius cubed)◦Thus, costs increase by 2/3 for each doubling
For IC Wafers, LCD and Solar Substrates◦Processing time per area (inverse of output) fall as
volume of gas, liquid, and reaction chambers become larger; costs rise as function of equipment’s surface area
◦Transfer times per area may also fall with larger substrates
◦Larger wafers/substrates have smaller edge effects
One Benefit from Large Panels is Smaller Edge Effects
LCD or Solar Substrate
Equipment
Effect Effects: the equipment must be much wider than panel to achieve uniformity
Ratio of equipment to panel width falls as the size of the panel is increased

For your ProjectsDoes your technology benefit from increases or
decreases in scale? If so, what kind? Smaller or larger?◦Can we analyze this scaling and the potential cost reductions
from scaling◦Can we estimate when might these benefits from geometric
scaling lead to a superior value proposition for some set of users? most users?
Also what are the potential limits from geometric scaling? Or are there complementary technologies that are needed to benefit from geometric scaling
If the technology does not benefit from increases or decreases in scale, maybe a “key” component does

ComputersNote the similar levels of improvements between 1960 and 2000 (about 7 orders of magnitude)
Source: ICKnowledge, 2009; Koh and Magee, 2006)
As one computer designer argued, by the late 1940s computer designers had recognized that “architectural tricks could not lower the cost of a basic computer; low cost computing had to wait for low cost logic” (Smith, 1988)
Magnetic Resonance Imaging (MRI) and Computer Tomography (CT)
Improvements in MRI and CT were driven by improvements in computers and they were driven by improvements in ICs
Quote by Trajtenberg (1990)◦“However, it was not until the advent of microelectronics
and powerful mini-computers in the early seventies, the early seventies, coupled with significant advances in electro-optics and nuclear physics, that the revolution in imaging technologies started in earnest. Computed Tomography scanners came to epitomize this revolution and set the stage for subsequent innovations, such as………..and the wonder of the eighties, Magnetic Resonance Imaging”
Quotes from Kalendar, 2006◦ “Computed tomography became feasible with the development of
modern computer technology in the 1960s”
Wireless TransportNote reductions in feature sizes, which were needed for new cellular systems
Components and Systems (1)Some components have a large impact on
performance of a systemComponents that benefit from scaling can
◦have a large impact on performance and cost of systems, even before system is implemented
◦lead to changes in relative importance of cost and performance and between various dimensions of performance
◦lead to discontinuities in systemsImprovements in components may enable
new forms of systems to emerge
Components and Systems (2)Improvements in engines impacted on
◦Locomotives, ships◦Automobiles, aircraft
Improvements in ICs impacted on◦computers, servers, routers, telecommunication
systems and the Internet◦radios, televisions, recording devices, and other
consumer electronics◦mobile phones and other handheld devices◦controls for many mechanical products
Improvements in ICs led to many discontinuities in systems
Laptops MP3 PlayersCalculators Video Set-top boxes E-Book ReadersDigital Games Web Browsers Digital TV Watches Mobile Digital Cameras Smart PhonesPCs Phones PDAs Tablet Computers
Increases in the Number of Transistors Make New Forms of Electronic Products Economically Feasible
Components and Systems (3)Improvements in ICs are still driving
emergence of new electronic systems such as new forms of◦Autonomous vehicles◦Holographic display systems◦3D scanners◦Eye tracking◦Wireless charging◦Google glasses, LEAP (gesture interfaces), and
augmented reality◦New mobile phone systems (e.g., 4G, 5G, cognitive
radio)◦Networks of RFID tags, smart dust, and other
sensors
Components and Systems (4)
Similar things are happening with bio-electronics, MEMS, nanotechnology: they are enabling new forms of systems to emerge◦point-care diagnostic devices◦Other forms of sensors and sensor-based systems◦Even new forms of mobile phones
Better forms of DNA sequencers and synthesizers are being driven by reductions in scale of features. They will impact on higher-level systems (e.g., health care system)
For these and other TechnologiesWhat is the minimum level of performance in a
component (such as an IC) that might enable a new electronic system to offer a superior value proposition in for example,◦Gesture and neural-based human-computer interfaces?◦Cognitive radio for mobile phone systems?◦Autonomous vehicles?
When the concepts and principles that form the basis for a new system are relatively well known, components are often the bottleneck for new systems
Summary (1)
Technologies that experience large improvements in performance and cost are more likely to create new opportunities than are other technologies
These two “mechanisms” provide a better understanding of how and why improvements occurred in some technologies more than in others◦ Creating materials that better exploit physical phenomena◦ Geometrical scaling
We can use these mechanisms to think about when a new technology might offer a superior value proposition
Summary (2)Think about how these mechanisms apply to a
specific technology for group project◦ Creating materials that better exploit physical phenomena
◦ Geometrical scaling (reductions and/or increases in scale)
◦ Both directly or indirectly (Impact of components on higher level systems)
For the technology, think about◦ current advantages and disadvantages when compared to
old technology
◦ sources and rates of improvement in new technology
◦ might these rates accelerate or de-accelerate?
◦ What kinds of new systems, i.e., entrepreneurial opportunities will these changes create?
Summary (3)
Be specific about the components in your technology and their ◦ rates of improvement◦do we expect these rates to accelerate or de-
accelerate?◦Do these components benefit from some kind of
scaling, such as reductions in scale?For many of your projects, the rates of
improvements in the components will determine the rates of improvements for your system
