description

These slides summarize four kinds of improvements that are often exponential in nature: 1) improving the efficiency by which basic concepts and their underlying physical phenomena are exploited; 2) radical new processes; 3) geometric scaling; 4) improvements in “key” components. For the first one, finding materials that better exploit a physical phenomenon often leads to improvements in efficiency (e.g., batteries, LEDs). Second, some technologies experience improvements as their scale is reduced (e.g., ICs, MEMS, bio-electronic chips, nanotechnology) while some experience improvements as their scale is increased (engines, transportation equipment, LCD or solar substrates). Finally, some components have a large impact on the performance and cost of a system and rapid improvements in these components (e.g., ICs) can lead to rapid improvements in the performance and cost of some systems (e.g., computers, mobile phones). These slides are based on a forthcoming book entitled “Technology Change and the Rise of New Industries and they are the second session in a course entitled “Analyzing Hi-Tech Opportunities.”

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

Page 3: How Improvements in Performance and Cost Occur, i.e., what are the mechanisms?

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?

Page 4: How Improvements in Performance and Cost Occur, i.e., what are the mechanisms?

Performance Occur, i.e., what are the mechanisms? ◦Creating materials that better exploit physical

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

Items 1, 2, 3: involve lighting

Page 12: How Improvements in Performance and Cost Occur, i.e., what are the mechanisms?

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).

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

Page 25: How Improvements in Performance and Cost Occur, i.e., what are the mechanisms?

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?

Page 29: How Improvements in Performance and Cost Occur, i.e., what are the mechanisms?

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

Page 30: How Improvements in Performance and Cost Occur, i.e., what are the mechanisms?

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?

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

Page 35: How Improvements in Performance and Cost Occur, i.e., what are the mechanisms?

Christensen’s theory of disruptive innovation also implies that performance improvements automatically emerge once a low-end innovation has been found

Page 36: How Improvements in Performance and Cost Occur, i.e., what are the mechanisms?

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?

Other Technologies that Benefit from Reductions in Scale (1)

Bio-electronic ICs (MEMS with micro-fluidic channels) for many applications◦Point-of-care diagnostics ◦Drug delivery◦chips embedded in clothing, body, etc.

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

Page 44: How Improvements in Performance and Cost Occur, i.e., what are the mechanisms?

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…

Page 45: How Improvements in Performance and Cost Occur, i.e., what are the 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,

Page 46: How Improvements in Performance and Cost Occur, i.e., what are the mechanisms?

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)

Page 47: How Improvements in Performance and Cost Occur, i.e., what are the mechanisms?

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

Page 48: How Improvements in Performance and Cost Occur, i.e., what are the mechanisms?

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

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)

Page 54: How Improvements in Performance and Cost Occur, i.e., what are the mechanisms?

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

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

Page 60: How Improvements in Performance and Cost Occur, i.e., what are the mechanisms?

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

Page 61: How Improvements in Performance and Cost Occur, i.e., what are the mechanisms?

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

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

OutlineValue Proposition and economic feasibilityExisting theories of technological changeWhat Drives Improvements?

◦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”

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”

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

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

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

Page 90: How Improvements in Performance and Cost Occur, i.e., what are the mechanisms?

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?

Page 91: How Improvements in Performance and Cost Occur, i.e., what are the mechanisms?

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
