Dear All,
This is an apology as I made an error trying to translate from the
Babylonian era minutes and hours and I was out by a factor of the
Babylonian factor — 60.
Here are the revised figures for energy use:
Some other approximate values (to compare with walking) are:
Cycling 80 joules per metre
Walking 150 joules per metre
Jogging 270 joules per metre
But note that some human activities take much more energy
Swimming 1 000 joules per metre (not 60 000 joules per metre as I
wrote previously)
For motor transport (numerical factors from http://bioenergy.ornl.gov/papers/misc/energy_conv.html
)
Motor bike 150 joules per metre
Car 300 joules per metre
Truck 600 joules per metre
Cheers,
Pat Naughtin
P.S. I hate having to use Babylonian factors any time but especially
when it leads to errors that are so easily made!
