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.

Bridge over the River Kwai

 

 

In 1957-58 the film ‘The Bridge on the River Kwai‘ was ground breaking.  It was remarkable for being mainly shot on location (in Ceylon not Thailand) rather than in a studio and for involving the construction and demolition of a real, fully functioning rail bridge.   It's still regarded by many as one of the finest movies ever made. 

One of the things a tourist to Bangkok is encouraged to do is to take a day trip to the actual bridge.

More on Technology and Evolution

 

 

 

 

 

I recently read and commented on Dan Brown's latest novel 'Origin' in which the question 'where are we going?' is answered in suggesting an ever greater human symbiosis with technology.  But what if that's not all?

Regular readers will know that I have an artificial heart valve.  Indeed many people have implanted prosthesis, from metal joints or tooth fillings to heart pacemakers and implanted cochlear hearing aides, or just eye glasses or dentures.   Some are kept alive by drugs.  All of these are ways in which our individual survival has become progressively more dependent on technology.  So that should it fail many would suffer.  Indeed some today feel bereft without their mobile phone that now substitutes for skills, like simple mathematics, that people once had to have themselves.  But while we may be increasingly transformed by tools and implants, the underlying genes, conferred by reproduction, remain human.

The possibility of accelerated genetic evolution through technology was brought nearer last week when, on 28 November 2018, a young scientist, He Jiankui, announced, at the Second International Summit on Human Genome Editing in Hong Kong, that he had successfully used the powerful gene-editing tool CRISPR to edit a gene in several children.

More Julian Assange

 

 

A friend forwarded me an article by Elizabeth Farrelly in the Sydney Morning Herald on April 12.  Read Here or click on the picture.



It appears that Assange's theories about petite and grand conspiracies are well founded; and illustrated by his own case.
