The Challenge is to Keep the Atmosphere Stable.
To do this we must take a long term view and
engineer a new way for us to live.

Even if the annual flow of emissions was frozen
today, the level of greenhouse gas in the
atmosphere would still reach double its
pre-industrial levels by 2050. In fact, emissions
are increasing rapidly and the level of 550 ppm
could be reached as early as 2035.

4Balancing CO2 in the Atmosphere
- The problem is fundamentally one of CO2 balance,
not emissions - There are two ways the CO2 in the atmosphere can
be balanced - By reducing emissions.
- By using (sequestering) at least as much carbon
as we produce. - Both strategies require
- technological change on a scale never before
imagined. - A high long term high price for carbon to drive
investment that will result in this change.
5Where are we?
- The Kyoto Protocol
- A treaty intended to implement the objectives and
principles agreed in the 1992 UN Framework
Convention on Climate Change (UNFCCC). - Requires governments to agree to quantified
limits on their greenhouse gas emissions, through
sequential rounds of negotiations for successive
commitment periods. - The Kyoto treaty is the result of political
negotiation and diplomatic compromise and on the
surface not a lot more than short term promises
to reduce emissions that make politicians look
good, but that their successors cannot possibly
keep. - The Kyoto treaty is not a viable strategy for
survival in the future - A treaty agreeing to a
long term plan is required. - Constraint
- With lots of silly targets with no strategy for
their achievement - Talk about Carbon Capture and Storage
- Not a lot else
6World Economic Growth and Energy Intensity
GDP is rising on a per capita basis and because
of population growth. At the same time due to
technological improvements that have resulted in
increasing thermodynamic efficiencies as well as
some sectoral change energy consumption per unit
of GDP (energy intensity) has been falling. As a
result emissions have not been rising as fast as
GDP.

8The Correlation Between WIP and Emissions
- The correlation between emissions and GDP is high
because - Fossil fuels supply 90 of the world's energy.
- Energy is used to produce goods (WIP)
- Only in recent years
- have we been seriously trying to improve
efficiency (most of the Kyoto effort) - there has been a shift to services with lower CO2
intensity

9The Limits to Efficiency Improvements
There are may ways the second law of
thermodynamics can be enunciated but relevant to
us is Lord Kelvins version. It is impossible
to convert heat completely into work Using
Carnots law it is possible to calculate the
theoretical maximum efficiency of any heat engine
such as a power station turbine or engine of a
car, bus or train. (Try the calculator at
http//hyperphysics.phy-astr.gsu.edu/hbase/thermo/
carnot.html) Most heat engines run at much lower
efficiencies than the theoretical limit so there
is still scope for improvements however the law
of diminishing returns applies in terms of cost.
10Efficiency Limitations to Emissions Reduction

Rate of Per Capita Emissions Reduction
Per capita emissions reduction through Pilzer 1st
law substitution (Technology change resource

Per capita emissions reduction through
thermodynamic efficiency
The Future
2008
Conclusion It is essential that R D into
substitution technologies occurs now in order to
ramp up Pilzer first law substitution later and
avoid thermodynamic constraints. This is not
happening in Australia

Assuming Kyoto commitments are met (which is
unlikely) it is estimated that global emissions
will be 41 higher in 2010 than in 1990, 1 less
than without Kyoto.

The current round of inflation has less to do
with dangerous underlying demand than with real
shortages in oil. Crippling our economy by
cranking up interest rates is about the most
stupid thing a government can do as the economy
needs to be in good shape to adapt to resource
use change.

17Reducing the CO2 in the air without Curtailing GDP
- The challenge is to find ways of reducing CO2 in
the air without negatively impacting the economy. - Substitution to Non Fossil Fuel Sources of Energy
- Geothermal, Wind, Solar etc.
- Nuclear
- Sequestration on a Massive Scale
- Geo-sequestration (clean coal, hydrogen fuel
etc.) - limited - Anthropogenic sequestration in the built
environment - our preferred option
18Geosequestration
- Is not safe due to leakage (China recently?)
- Is not likely to be ready before 2015 for coal
fired power stations in Australia - Authoritative published studies estimate the cost
of geosequestration at between 30-140/tCO2. (a
wide range due to so many uncertainties) - Added to the cost of coal or hydrogen, these
sources of energy with geosequestration may be
more expensive that alternatives.
A long term plan would included the required R
D now
19Affect of Leakage on Geosequestration
"The assumption of exclusive reliance on storage
may be an extreme one, however the example
illustrates that emphasis on energy efficiency
and increased reliance on renewable energy must
be priority areas for greenhouse gas mitigation.
The higher the expected leakage rate and the
larger the uncertainty, the less attractive
geosequestration is compared to other mitigation
alternatives such as shifting to renewable energy
sources, and improved efficiency in production
and consumption of energy."

20Synopsis
- We must accept our long term role of maintaining
spaceship earth as planetary engineers and find
ways of maintaining the level of carbon dioxide,
oxygen and other gases in the atmosphere at
desirable levels. - We cannot possibly arrest the alarming increases
in atmospheric carbon dioxide currently occurring
through efficiency, emissions reduction
(constraint) or substitution alone - Geo-sequestration is at best short term and at
worst highly risky. What would have happened
recently if the Chinese were using the
technology? - We have a good chance of preserving the future if
we mimic nature and find profitable uses for
carbon and other wastes.
21Synopsis
- Uses for carbon and other wastes must be
economically driven and result in a real value
that puts profit in the pocket of a large number
who will as a consequence wish to engage
otherwise they cannot be implemented on the
massive scale required. - Anthropogenic sequestration as man made carbonate
in the built environment is a new technology
platform that has the promise of profitably
sequestering massive amounts of carbon
profitably. - The markets created for man made carbonate in
buildings are insatiable, large enough and
indefinitely continuing. - Anthropogenic sequestration by building with man
made carbonate is doable and most likely presents
the only option we have for saving the planet
from runaway climate change until such time as
safe and reliable forms of energy alternative to
fossil fuels can be developed - Anthropogenic sequestration by building with man
made carbonate must be part of any long term
planetary maintenance strategy.
22Learning to Use Carbon - Geomimicry for Planetary
Engineers?
- Large tonnages of carbon (7 of the crust) were
put away during earths geological history as
limestone, dolomite and magnesite, mostly by the
activity of plants and animals. - Orders of magnitude more than as coal or
petroleum! - Shellfish built shells from carbon and trees turn
it into wood. - These same plants and animals wasted nothing
- The waste from one is the food or home for
another. - Because of the colossal size of the flows
involved the answer to the problems of greenhouse
gas and waste is to use them both in an
insatiable, large and indefinitely continuing
market. - Such a market exists for building and
construction materials.
23Geomimicry for Planetary Engineers?
- The required paradigm shift in resource usage
will not occur because it is the right thing to
do. - Can only happen economically.
- To put an economic value on carbon and wastes
- We have not choice but to invent new technical
paradigms such as offered by TecEco and the
Global Sustainability Alliance (Gaia
Engineering). - Evolving culturally to effectively use these
technical paradigms - By using carbon dioxide and other wastes as
building materials we can economically reduce
their concentration in the global commons.

26Anthropogenic Sequestration of Carbon and Wastes
- During earth's geological history large tonnages
of carbon were put away as limestone and other
carbonates and as coal and petroleum by the
activity of plants and animals. - Sequestering carbon in calcium and magnesium
carbonate materials and other wastes in the built
environment mimics nature in that carbon is used
in the homes or skeletal structures of most
plants and animals.

27Geomimicry
- There are 1.2-3 grams of magnesium and about .4
grams of calcium in every litre of seawater. - There is enoughcalcium and magnesiumin seawater
with replenishmentto last billions of years at
current needs for sequestration. - To survive we must build our homes like these
seashells using CO2 and alkali metal cations.
This is geomimicry
- Carbonate sediments such as these cliffs
represent billionsof years of sequestrationand
cover 7 - 8 of the crust.

29Building and Construction Represents an
Insatiable, Large and Indefinitely Continuing
Market for Anthropogenic Sequestration
- The built environment is made of materials and is
our footprint on earth. - It comprises buildings and infrastructure.
- Construction materials comprise
- 70 of materials flows (buildings, infrastructure
etc.) - 40-50 of waste that goes to landfill (15 of
new materials going to site are wasted.) - Around 50 billion tonnes of building materials
are used annually on a world wide basis. - The single biggest materials flow (after water)
is concrete at around 18 billion tonnes or 2
tonnes per man, woman and child on the planet. - 40 of total energy in the industrialised world
(researchandmarkets)
Why not use magnesium carbonate aggregates and
building components from Greensols and
Eco-Cements from TecEco to bind them together?
30Only the Built Environment is Big Enough
The built environment is our footprint, the major
proportion of the techno-sphere and our lasting

31Economically Driven Technological Change
New, more profitable technical paradigms are
required that result in more sustainable and
usually more efficient moleconomic flows that
mimic natural flows or better, reverse our
damaging flows.
- ECONOMICS -
Change is only possible economically. It will not
happen because it is necessary or right.
32Consider Sustainability as Where Culture and
Technology Meet
Increase in demand/price ratio for greater
sustainability due to cultural change.
Supply
Equilibrium Shift
Greater Value/for impact (Sustainability) and
economic growth
ECONOMICS
We must rapidly move both the supply and demand
curves for sustainability
Demand
Increase in supply/price ratio for more
sustainable products due to technical innovation.
A measure of the degree of sustainability is
where the demand for more sustainable
technologies is met by their supply.
33Changing the Technology Paradigm
It is not so much a matter of dematerialisation
or constraint as a question of changing the
underlying moleconomic flows. We need materials
that require less energy to make them, do not
pollute the environment with CO2 and other
releases, last much longer and that contribute
properties that reduce lifetime energies. The key
is to change the technology paradigms
- By enabling us to make productive use of
particular raw materials, technology determines
what constitutes a physical resource1 - Pilzer, Paul Zane, Unlimited Wealth, The Theory
and Practice of Economic Alchemy, Crown
Publishers Inc. New York.1990
Or more simply the technical paradigm
determines what is or is not a resource!
34Cultural Change is Happening!
- Al Gore (SOS)
- CSIRO reports
- STERN Report
- Lots of Talkfest
- IPCC Report
- Political change
- Branson Prize
- Live Earth (07/07/07)
The media have an important growing role
35Why Magnesium Carbonates?
- Because of the low molecular weight of magnesium,
it is ideal for scrubbing CO2 out of the air and
sequestering the gas into the built environment - Due to the lighter molar mass of magnesium more
CO2 is captured than in calcium systems as the
calculations below show. - At 2.09 of the crust magnesium is the 8th most
abundant element - Sea-water contains 1.29 g/l compared to calcium
at .412 g/l - Magnesium compounds have low pH and polar bond in
composites making them suitable for the
utilisation of other wastes.
36Making Carbonate Building Materials to Solve the
Global Warming Problem
- Magnesium materials from Gaia Engineering are
potential low cost. New kiln technology from
TecEco will enable easy low cost simple non
fossil fuel calcination of magnesium carbonate to
make binders with the CO2 recycling to produce
more carbonate building material to be used with
these binders. - How much magnesium carbonate would have to be
deposited to solve the problem of global warming? - The annual flux of CO2 is around 12 billion
tonnes 22.99 billion tonnes magnesite - The density of magnesite is 3 gm/cm3 or 3
tonne/metre3 - 22.9/3 billion cubic metres 7.63 cubic
kilometres of magnesite would have to be
deposited each year. - Compared to the over seven cubic kilometres of
concrete we make every year, the problem of
global warming looks surmountable. - If magnesite was our building material of choice
and we could make it without releases as is the
case with Gaia Engineering, we have the problem
as good as solved!
Anthropogenic sequestration - building with
carbonate and waste is the answer
