Dear Pat:
No question about it. I wish the author had used, at least in the calculations,
SI only; the equations and comparisons would be simpler. However, being used to
the muddle of units seen in the US, the books seems VERY metric. The note from
me should have been more specific by saying not just "METRIC" but also "not
necessarily SI."
I agree with you on the terminology also. The book seems a bit hastily written.
The amount of information provided in this work makes me to forgive the units
mess and inconsistent terminology. I had not come across a better and more
complete treatment of this subject from an English language native author in
metric than this.

Dear Stan,
Thanks for this reference. The writer has done some fascinating research and
I particularly like the presentation of the graphical information.
However, I was appalled at the author's complete muddling of the two physical
quantities: power and energy. Like many modern media sources, I had to stop
every time he chose to use the word power to see if he really meant energy and,
more unusually, vice versa.
Another problem is his use of old pre-metric measures (such as miles per
gallon) inter-muddled with metric and SI units. It's a real nuisance that he
felt he had to do this in what is otherwise a good source of information about
sustainable energy.
I suppose that your perceptive and mine differ quite a bit.
You say that the book 'is METRIC' and I suppose it is when viewed from your
environment in the USA.
I say it still has a lot of metric measurement problems and issues when
viewed from an Australian environment.
Cheers,
