Converting Heat to Work
Since pre-history we knew how to:
Work

Industrial Revolution to:

Newcomen’s Steam Engine

Revolutionary Change Transforms
Economy: textile production increases 150 fold
and prices drop 90%
Place: cities grow from 5% to 50%
Family: parents leave home to work
Geography: steam ship and railroad

Economic Explosion
Pre-industrial

Industrial revolution
US/Europe income
$600 to $18,000
Increases 30x!
Energy Revolution Creates Modern World
Single Most Important Event
in Human History
The Nature of Wealth
James Watt observed that a horse
pulling 180 pounds of force made
144 trips around the circle in an
hour, at an average speed of 181
feet per minute = 33,000 ft. lbs.
per minute = one “horsepower”.
Generating 1 hp required:
1,500 lb horse
6 ft tall
costs $5,000 /yr to board
Today, generating 1-hp
requires:
32 lb motor (30x less)
4 x 6 inches (12x less)
costs $250 /year to
power (20x less)
We’ve Come a Long Way…
Newcomen’s steam engine: 0.5%
Watt’s steam engine: 1%
Gasoline engines: 30%
Coal Rankine cycles: 35%
Turbines: 40%
Diesel engines: 50%
Combined-cycle turbine/Rankine engines: 60%
But Energy Conversion
Largely Unchanged…
1. Use hydrocarbon fossil fuels
2. Employ combustion to release heat
CH4+2(O2 + 3.76 N2)=CO2+2H20+(NOx+SOx+…)
3. Convert heat to work via thermal expansion
84% Of World Energy
From Fossil Fuels
In U.S. 86% from non-renewable fossil fuels

Consequences of Peak Fuel
• Rising demand and falling supply
rapidly increases fuel prices
• Rising fuel prices reduce
expendable income and cause
recessions
• Rising fuel prices drain fuel
importing economies and increase
trade deficits
• Competition for dwindling supply
increase national security risks
• Rising fuel prices support
undemocratic regimes (Russia,
Middle East, Venezuela, etc.)
Environmental Perspective
“Using energy in today’s ways leads
to more environmental damage than
any other peaceful human activity.”
The Economist, 1990.

Debate?
Consensus view from:
Intergovernmental Panel on Climate Change (IPCC)
Every U.S. scientific body (NAS, AMS, AGU, AAAS)
Every G8 National Academy of Science’
Literature review (Oreskes, Science, Vol. 306, 2004):
All scientific peer-reviewed journals from 1993 – 2004 with key
words “climate change”.
Found 983 papers
NONE disagreed with consensus position
“The need for urgent action to address
climate change is now indisputable.”
U.S. National Academy of Sciences
and counterpart academies from 12
other nations. 2009
