– European Union
– Japan
• Building Industrial Strength in Asia
– China
– S. Korea, Malaysia, Taiwan, Singapore
2020 and beyond
• China has a chance to be
– Industrial Leadership of the World
– Super Power
• This can happen if China can solve some
problems

Energy Problems
• Today
– Oil is not where the industrial development is.
– Not enough oil for future demand.
• What is Future Energy Mix
Todays’s Reading Assignment
“Hubbert’s Peak” by Kenneth Deffeyes (2001)
• King Hubbert predicted US oil production would peak in
1970.
– It did.
• The same approach predicts World Oil production will
peak within this decade.
– It will.
• The days of cheap energy from oil will then be gone.

Why the Growth in Demand?
• Population increases around the world.
• GDP increases around the world.
• Projections assume improved energy
efficiency.
Population Growth to
10 Billion People in
2050

What is going to fill the Energy gap?
• Coal
• Nuclear Energy
• Renewable Energy

14 Enabling Nanotech Revolutions
1. Photovoltaics -- a revolution to drop cost by 10 to100 fold.
2. H2 storage -- a revolution in light weight materials for pressure tanks ,
and/or a new light weight, easily reversible hydrogen chemisorption system
3. Fuel cells -- a revolution to drop the cost by nearly 10 to 100 fold
4. Batteries and supercapacitors -- revolution to improve by 10-100x for
automotive and distributed generation applications.
5. Photocatalytic reduction of CO2 to produce a liquid fuel such as methanol.
6. Direct photoconversion of light + water to produce H2
7. Super-strong, light weight materials to drop cost to LEO, GEO, and later the
moon by > 100 x, to enable huge but low cost light harvesting structures in
space; and to improve efficiency of cars, planes, etc.
8. Nanoelectronics to revolutionize computers, sensors and devices.
14 Enabling Nanotech Revolutions
9.
High current cables (superconductors, or quantum conductors) with which
to rewire the electrical transmission grid, and enable continental, and even
worldwide electrical energy transport; and also to replace aluminum and
copper wires essentially everywhere -- particularly in the windings of electric
motors (especially good if we can eliminate eddy current losses).
10.
Thermochemical catalysts to generate H2 from water that work efficiently at
temperatures lower than 900 C.
11.
CO2 mineralization schemes that can work on a vast scale, hopefully starting
from basalt and having no waste streams.
12.
Nanoelectronics based Robotics with AI to enable construction maintenance
of solar structures in space and on the moon; and to enable nuclear reactor
maintenance and fuel reprocessing.
13.
NanoMaterials/ coatings that will enable vastly lower the cost of deep
drilling, to enable HDR (hot dry rock) geothermal heat mining.
14.
Nanotech lighting to replace incandescent and fluorescent lights

The biggest single challenge for the next few decades:
ENERGY
for 1010 people
•
. At
MINIMUM we need 10 Terawatts (150 M BOE/day)
from some new clean energy source by 2050
•
For worldwide peace and prosperity we need it to be cheap.
•
We simply can not do this with current technology.
•
We need people to enter Physical Science and Engineering as they
did after Sputnik.
•
Inspire a sense of MISSION
( BE A SCIENTIST
SAVE THE WORLD )
• We need to find NEW ENERGY TECHNOLOGIES
Tomorrow’s Reading Assignment
“The Hydrogen Economy: The Next Great Economic
Revolution” by Jeremy Rifkin
(Tarcher/Putnam, 2002)
H2 is not a primary energy source.
But, after natural gas, it probably will be
our future transportation fuel
and energy storage medium.
