Pages 2, 18 Apologies to Jonathon Porritt for mis-spelling his
first name.
Page 30-31 Note 29. In the sentence,
If I said "the average use of energy for car driving
in the UK is 24 kWh/d per person," I bet some people would
misunderstand and say: "I'm a car driver so I guess I use 24 kWh/d."
replace both "24"s by "13".
(24 kWh/d/p was the average use of energy for all road transport.
Of that, 13 kWh/d/p goes into cars and motorcycles.)
Page 43 corn to ethanol (in figure 6.11)
"0.02 W/m**2" should be "0.048 W/m**2".
[Details: the power production of ethanol works out to 0.2 W/m**2;
unfortunately, producing the ethanol requires inputs
with a power _cost_ of 0.2 W/m**2, which cancels the power
produced. The only way to get net power from corn-to-ethanol is
to ensure that all co-products are exploited.
Shapouri et al then estimate that corn ethanol production
has an 'energy ratio' of 1.24, which means that the _net_ power
production of corn-to-ethanol is 0.048 W/m**2.]
Page 47 add parenthesis:
band-gap is lost. -> band-gap is lost.)
Page 55 Map showing Kinlochewe and Bedford: Kinlochewe is shown incorrectly.
The correct location is about 60km further north.
Page 56 (note 56, line 8) "has a per" -> "has a power per"
Page 62 line 14 from the bottom, ``0.14 million tons''
should read ``140 million tons''.
Page 63 ``Denmark, where windmills generate
9% of the electricity.''
should read
``Denmark, where windmills generate
19% of the electricity.''
[Danish wind production in 2008 was 3.4\,kWh/d/p;
their total gross electricity production was 18\,kWh/d/p. -source]
Page 75 Last line, "5%" should read "10%".
Page 81 Why are there two high tides and two low tides per day?
Well, if the earth were a perfect sphere, a smooth billiard ball covered by oceans,...
... Two humps of water cannot whoosh round the earth once per day because
the continents get in the way.
→ Why are there, in many places in the world, two high tides and two low tides per day?
Well, if the earth were a perfect sphere, a smooth billiard ball covered by
extremely deep oceans,...
... Two humps of water cannot whoosh round the earth once per day because
the oceans are too shallow and the continents get in the way.
Page 85 In the map of Northern Ireland the placename "Downpatrick"
is missing its first letter.
Page 120 trolleybuses consume
270 kWh per vehicle-km
should read
270 kWh per 100 vehicle-km
Page 131 "hydrogen gradually leaks out of any practical container. If you park
your hydrogen car at the railway station with a full tank and come back a
week later, you should expect to find most of the hydrogen has gone."
is incorrect and should be replaced by:
"hydrogen gradually boils off from cryogenic tanks to keep them cold.
If you park a cryogenic hydrogen car at the railway station with
a full tank and come back two or three weeks
later, you should expect to find most of the hydrogen has gone."
Page 133 "Rijnsdam" should read "Rijndam"
Page 153 "Scandanavia" should read "Scandinavia"
Page 167 "The nuclear decommissioning authority has an annual budget
of 2 billion." In fact this is to clean up not only
the civilian nuclear power stations but also the military
nuclear-bomb-making facilities at Sellafield. The lion's share of
the money is thus cleaning up military mess, not
civilian-power mess. This means I have overestimated
the cost per kWh of cleaning up old civilian nuclear power.
Page 169-170 "after 1000 years, the radioactivity of the
high-level waste is about the same as that of uranium ore."
→
"if we reprocess the waste, separating off the uranium
and plutonium for use in new nuclear fuel, then
after 1000 years, the radioactivity of the
high-level waste is about the same as that of uranium ore."
Page 181 Figure 25.8, caption:
"one-third-filled" should read "one-half-filled".
Page 192 Table 26.7. Columns 2 and 3: volumes and depths are wrong.
All volumes (40, 40, 100...) and depths (20, 10, 20...)
should be doubled (to 80, 80, 200... and 40, 20, 40...
respectively).
Page 199 Figure 26.13, last sentence of caption:
"reduced" should read "reduced from".
Page 204 The red box marked Transport (20 kWh/d)
and the adjacent blue box marked Electricity (18 kWh/d)
were both accidentally misdrawn 10% too tall.
Page 205 paragraph 2, last line,
"2 kWh/d/p of solar hot water,"
should be
"1 kWh/d/p of solar hot water,"
Page 206 fig 27.2 Teeside should be Teesside
Page 207 Last paragraph, fourth line:
Waste incineration: "1.3 kWh/d/p" should read "1.1 kWh/d/p".
Page 217 "the cost of decommissioning the UK's nuclear power stations."
→
"the cost of decommissioning the UK's nuclear power stations
and nuclear-weapon factories."
Page 232 "Scandanavia" should read "Scandinavia"
Page 234 "250 kWh/d per day" should read "250 kWh per day".
Page 238 paragraph 2: Brazilian sugarcane
- See erratum for page 284, below.
Page 241 Figure 31.2's discussion of the amount of carbon in the atmosphere
should have clarified that the amount shown (600 Gt) is the
pre-industrial
amount. Since 1850, the amount of carbon in the atmosphere
has increased to roughly 800 Gt.
Page 246 To pulverized the rocks → To pulverize the rocks
Page 260 The numeric value of the speed at which a car's rolling resistance is
equal to air resistance is incorrect.
"7 m/s = 16 miles per hour" should be replaced by
"13 m/s = 29 miles per hour".
Page 263 Fig B.1: force 7, 31 km/h → 58 km/h
Page 281 line 2: depends only → depends only on
Page 284 Bioethanol section: "0.02 W/m**2" should be "0.2 W/m**2".
To make this section more informative I would rewrite
it thus:
1 acre produces 122 bushels of corn per year, which makes
122 x 2.6 US gallons of ethanol, which at 84000 BTU per gallon would
mean a power per unit area of {0.2 W/m^2}; however, the energy
inputs required to process the corn into ethanol amount to
83,000 BTU per gallon; so 99% of the energy produced is used up by
the processing, and the net power per unit area is about
{0.002 W/m^2}. The only way to get significant net power from the
corn-to-ethanol process is to ensure that all co-products are
exploited; including the energy in the co-products, the net power per
unit area is about 0.05 W/m^2.
Page 285 End of paragraph 1:
230 square metres ... roughly 6% ...''
→
100 square metres ... roughly 3% ...''.
Page 286 If 2800\,m^2 of Britain (that's all agricultural
land) ...
→
If 2800\,m^2 per person of Britain (that's all agricultural
land) ...
Page 298, 299 The top line of page 298 gives 6.6 W/m^2 as
the total power per unit area
of the Heatkeeper house. This is incorrect. 6.6 W/m^2 is the heating
power only. The total power per unit area is 12.2 W/m^2.
This error is repeated in figure E.12.
[Incidentally the equivalent breakdown of power
consumption in my house, "after",
is 6.2 W/m^2 of gas and 7.1 W/m^2 total.]
Page 299 Another problem with figure E.12 is that the PassivHaus standards
use a different convention for defining power: power is
measured in terms of "primary energy consumption", which
requires knowledge of the sources of electricity and fuel and
of conversion efficiencies. This means that the PassivHaus
standards are actually more stringent than the figure shows; though
exactly how much more stringent depends on the fuel mix.
Page 300 Figure E.13: "Text" should read
"Tout", for consistency with the caption.
Page 316 The equation number (G.10) is missing from the equation on this
page.
Page 324 line 22 "(10 kWh/d per person)" should read "(10 kWh per kg)"
Page 328 line 6
``Internationale" should read ``International".
