The following paper was written back in 2007.  Since that time the Global Financial Crisis (GFC) struck and oil prices have not risen as projected.  But we are now hearing about peak oil again and there have been two programmes on radio and TV in the last fortnight floating the prospect of peak oil again. 

At the end of 2006 the documentary film A Crude Awakening warned that peak oil, ‘the point in time when the maximum rate of petroleum production is reached, after which the rate of production enters its terminal decline’, is at hand. 

Perhaps the most important argument in A Crude Awakening is that energy, including oil, replaces human labour and does so very efficiently.  It is the harnessing of energy that has allowed human civilisation to free people from slavery and serfdom and it is the harnessing of energy that has fuelled technological progress. 

It has also fuelled an increase in human population from less than a billion in 1800 to over six and a half billion today.

The most obvious defect in the documentary is that it represents oil as the only source of energy available to mankind.  This is not the case.  Until quite recently coal was the dominant energy source.  Coal fuelled the industrial revolution.  In some parts of the world hydroelectric power was also an important driver of industrialisation before oil and, where available, is still the most environmentally friendly and least expensive energy source we have. 

It is true that petroleum (oil and gas) has recently taken over the leading position as principle energy source; and contributor to carbon dioxide production.  Petroleum is more convenient and has higher energy density than most other options (see below) and produces less carbon dioxide per unit of energy than coal. It dominated transport and chemical production for the last two thirds of the 20th century and will continue to do so for at least the first half of the 21st.

The following diagram shows the sources of energy (for all purposes) in Australia in 2007/8[1].

It was oil that made the Second World War possible, oil that provided a car to every family soon after and oil that opened the world to inexpensive air travel. 

A Crude Awakening makes the point that we have already half used this amazing resource, in a shockingly spendthrift way, over an extraordinarily short period of time.

Morocco

 

 

 

In August 2008 we visited Morocco; before going to Spain and Portugal.  We flew into Marrakesh from Malta and then used the train via Casablanca to Fez; before train-travelling further north to Tangiers.

His life in a can

A Short Story

 

 

"She’s put out a beer for me!   That’s so thoughtful!" 

He feels shamed, just when he was thinking she takes him for granted.

He’s been slaving away out here all morning in the sweltering heat, cutting-back this enormous bloody bougainvillea that she keeps nagging him about.  It’s the Council's green waste pick-up tomorrow and he’s taken the day off, from the monotony of his daily commute, to a job that he has long since mastered, to get this done.  

He’s bleeding where the thorns have torn at his shirtless torso.  His sweat makes pink runnels in the grey dust that is thick on his office-pale skin.  The scratches sting, as the salty rivulets reach them, and he’s not sure that he hasn’t had too much sun.  He knows he’ll be sore in the office tomorrow.

Science, Magic and Religion

 

(UCLA History 2D Lectures 1 & 2)

 

Professor Courtenay Raia lectures on science and religion as historical phenomena that have evolved over time; starting in pre-history. She goes on to examine the pre-1700 mind-set when science encompassed elements of magic; how Western cosmologies became 'disenchanted'; and how magical traditions have been transformed into modern mysticisms.

The lectures raise a lot of interesting issues.  For example in Lecture 1, dealing with pre-history, it is convincingly argued that 'The Secret', promoted by Oprah, is not a secret at all, but is the natural primitive human belief position: that it is fundamentally an appeal to magic; the primitive 'default' position. 

But magic is suppressed by both religion and science.  So in our modern secular culture traditional magic has itself been transmogrified, magically transformed, into mysticism.
