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.

Travel

Argentina & Uruguay

 

 

In October 2011 our little group: Sonia, Craig, Wendy and Richard visited Argentina. We spent two periods of time in Buenos Aires; at the start and at the end of our trip; and we two nights at the Iguassu Falls.

The Atomic Bomb according to ChatGPT

 

Introduction:

The other day, my regular interlocutors at our local shopping centre regaled me with a new question: "What is AI?" And that turned into a discussion about ChatGPT.

I had to confess that I'd never used it. So, I thought I would 'kill two birds with one stone' and ask ChatGPT, for material for an article for my website.

Since watching the movie Oppenheimer, reviewed elsewhere on this website, I've found myself, from time-to-time, musing about the development of the atomic bomb and it's profound impact on the modern world. 

Nuclear energy has provided a backdrop to my entire life. The first "atomic bombs" were dropped on Japan the month before I was born. Thus, the potential of nuclear energy was first revealed in an horrendous demonstration of mankind's greatest power since the harnessing of fire.

Very soon the atomic reactors, that had been necessary to accumulate sufficient plutonium for the first bombs, were adapted to peaceful use.  Yet, they forever carried the stigma of over a hundred thousand of innocent lives lost, many of them young children, at Hiroshima and Nagasaki.

The fear of world devastation followed, as the US and USSR faced-off with ever more powerful weapons of mass destruction.

The stigma and fear has been unfortunate, because, had we more enthusiastically embraced our new scientific knowledge and capabilities to harness this alternative to fire, the threat to the atmosphere now posed by an orgy of burning might have been mitigated.

Method:

So, for this article on the 'atomic bomb', I asked ChatGPT six questions about:

  1. The Manhattan Project; 
  2. Leo Szilard (the father of the nuclear chain reaction);
  3. Tube Alloys (the British bomb project);
  4. the Hanford site (plutonium production);
  5. uranium enrichment (diffusion and centrifugal); and
  6. the Soviet bomb project.

As ChatGPT takes around 20 seconds to write 1000 words and gives a remarkably different result each time, I asked it each question several times and chose selectively from the results.

This is what ChatGPT told me about 'the bomb':

Carbon Capture and Storage (original)

(Carbon Sequestration)

At the present state of technological development in NSW we have few (perhaps no) alternatives to burning coal.  But there is a fundamental issue with the proposed underground sequestration of carbon dioxide (CO2) as a means of reducing the impact of coal burning on the atmosphere. This is the same issue that plagues the whole current energy debate.  It is the issue of scale. 

Disposal of liquid CO2: underground; below the seabed; in depleted oil or gas reservoirs; or in deep saline aquifers is technically possible and is already practiced in some oil fields to improve oil extraction.  But the scale required for meaningful sequestration of coal sourced carbon dioxide is an enormous engineering and environmental challenge of quite a different magnitude. 

It is one thing to land a man on the Moon; it is another to relocate the Great Pyramid (of Cheops) there.
