Title: Quiz
1Quiz 1
- The hole in the ozone layer is now known to be
caused by CFCs used in ______ - The Beijing Protocol was signed in 2001 to
regulate CFC emissions in the atmosphere T____
F______ - HCFC-22 contributes to both global warming and
thinning of ozone and is now heavily used by the
________to make __________
2The Rise of Industrial Society
- Harnessing new energy sources, linking modern
society to carbon and steam (and eventually
global warming). - James Watt and the invention of the steam
engine-1769. - Late 18th century, first concerns about smoke
nuisance
3Making Taller Chimneys Throw the Stuff Higher in
the Air!
- .to convey the noxious gases to such a height
that they shall be so intermingled with the
atmosphere as not to be injurious to health
1855. - 1846- 1853 more than 100 new tall chimneys a
year in London. Hell is a city much like
London-a populous and smoky city - Charles Dickens Hard Times (1854) a river that
ran purple with ill-smelling dye
4 Widespread Industrial Pollution
- The waters of the river Calder could be used as
grey ink in the 1860s. - In the same decade children routinely amused
themselves by setting fire to the waters of the
Bradford Canal. - In 1936, the waters of the Trent were lethal to
all animal and plant life for a stretch of 130
miles.

6The Rise of Oil
- For centuries a black fluid bubbled to the
surface. Skimmed off by Native Americans for
medicines, dyes, and weatherproofing teepees. - 1824-salt drillers in Kentucky run out of town
because they hit oil and made a foul mess. - Rising expense and demand for whale oil.
- 1859-Oil City, PA Theyve struck oil.a liquid
fossil fuel millions of years in creation. More
ancient carbon emissions into the atmosphere.
7John D. Rockefeller and the Rise of Standard Oil
- Belgian Inventor in 1860 developed first
internal combustion engine-Etiene Lenoir. - Otto Daimler and Karl Benz, German inventors,
by 1889 developed new versions for automobiles. - Internal combustion engine became single largest
factor in making petroleum the most important
energy source in the world. - made John D. Rockefeller the first billionaire.
8Automobiles Solving One Problem (Horse Manure)
and Creating Another (Global Warming)
- Street sweepers praised the automobile for making
their job easier less manure to pick up and
cart, fewer stables and manure pits, and not as
many animal carcasses to dispose of.
9Forcing the Market Eliminate Public Transportaton
- General Motors, Standard Oil of California,
Firestone Tire and Rubber joined forces to buy up
rail and trolley lines in cities across the
countries and then tear up the tracks. - At the same time, public funds were used to build
freeways because now everyone had to have a car
10Suburbunization of America made possible by the
car
- Huge expansion of suburbia after World War II
- Made it necessary for everyone to have TWO cars
11Automobiles, the Environment and Global Warming
Environmental impacts start with mineral
extraction and the production of the raw
materials that go into the parts of a car. For
example, iron ore gets turned into steel, which
now accounts for most of the mass in vehicles.
But steel can be recycled, and on average,
today's automobiles are about 75 percent
recyclable, and using recycled steel helps reduce
energy use and pollution
12Other automobile components
- Other metal components, such as aluminum (used in
some engine parts and wheels, for example) and
copper (used for wiring) are also largely
recycled. - The lead and acid in batteries are poisonous and
dangerous. But batteries can be recycled, if they
are returned to a service station, a parts store,
or brought to a municipal hazardous waste
facility. - Plastics, which are mostly made from petroleum,
are more difficult to recycle. - Some degree of pollution is associated with all
of these components, much of it due to the energy
consumption, air pollution, and releases of toxic
substances that occur when automobiles are
manufactured and distributed.
13In 2002 there were 590 million cars in the world.
That is one for every ten people. There are 140
million cars in the United States and 55 million
in Japan. This contrasts with just nine million
cars in China and 6 million in India.
1415 of the worlds people own 76 of the worlds
cars.
15Designing our way out of the problem
- You know you are in a stagnant industry when the
big product innovation of the past decade is more

16The Modern Car The Efficiency Problem
- The Problem
- At least 80 of the fuel consumed is lost through
exhaust and engine heat. - 95 of the energy used to move the car, 95 moves
the car, 5 moves the driver. - Thus, 1 of the energy consumed moves the driver.
17- The vehicle is about 20x heavier than the driver,
and the engine about 10x larger than is required
for most driving. - The large engine is required to accelerate the
heavy vehicle
18The Hyper Car Amory Lovins Concept
- the problem is the use of steel Steel is a
splendid material if weight is an unimportant or
advantageous factor, but in a car, weight is
neither - Carbon fiber composites (carbon, Kevlar, glass,
and other fibers) can cut weight by half or a
third. - Steamlining make the underside as smooth as the
top. - .
19- Doubled-efficiency tires already on the market.
- Can cut by half or more the power needed to move
car and passengers. - Cuts the weight of a Ford Taurus from 3,140 lbs
to 1,300 lbs
20- Reduces the need for other components based on
weight. - Indy 500 cars are currently made of carbon fiber
composites, and can withstand crashes with less
injury. - Currently expensive but more investment would
bring the price down, already used in other
industries, like boats - Replace the current complex mechanical systems
with solid state electronics and software. - An immediate benefit would be that the twenty or
so most frequent mechanical causes of breakdowns
would no longer be components of the car at all
21- Big automakers start with two major
disadvantages 1) they are big and 2) they are
automakers - Hypercars will more resemble computers with
wheels than cars with chips.
