In June 2013 we visited Russia.  Before that we had a couple of weeks in the UK while our frequent travel companions Craig and Sonia, together with Sonia's two Russian speaking cousins and their partners and two other couples, travelled from Beijing by the trans-Siberian railway.  We all met up in Moscow and a day later joined our cruise ship.  The tour provided another three guided days in Moscow before setting off for a cruise along the Volga-Baltic Waterway to St Petersburg; through some 19 locks and across some very impressive lakes.

Russia Cruise - Leaving a Lock

This river cruise was most interesting from a technical and geographical point of view.

Relatively flat countryside and many rivers and streams have allowed engineers to construct elaborate canal and lock systems across Europe and it is possible in summer to travel by boat or barge from the Baltic to the black sea and the Mediterranean; across Poland into France and Germany and connected countries; and even across the English Chanel.  In the north many of these waterways are frozen in winter but as we saw, they constitute a significant commercial asset for moving bulk materials and very large industrial components; in addition to tourist cruise ships.

In Russia (as in North America) the differing levels in large freshwater lakes also provides a significant hydroelectric power resource.

Malaysia

 

 

In February 2011 we travelled to Malaysia.  I was surprised to see modern housing estates in substantial numbers during our first cab ride from the Airport to Kuala Lumpur.  It seemed more reminiscent of the United Arab Emirates than of the poorer Middle East or of other developing countries in SE Asia.  Our hotel was similarly well appointed.

Australia Day according to ChatGPT

 

I've long been interested in the advent of artificial intelligence (AI). It's a central theme in my fictional writing (The Cloud and The Craft) and is discussed in my essay to my children 'The Meaning of Life' (1997-2017). So, I've recently been exploring the capabilities of ChatGPT.

As today, 26 January 2024, is Australia Day, I asked ChatGPT to: 'write 1000 words about Australia Day date'.  In a few minutes (I read each as it arrived) I had four, quite different, versions. Each took around 18 seconds to generate. This is the result:

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.
