Bali

At the end of February 2016 Wendy and I took a package deal to visit Bali.  These days almost everyone knows that Bali is a smallish island off the east tip of Java in the Southern Indonesian archipelago, just south of the equator.  Longitudinally it's just to the west of Perth, not a huge distance from Darwin.  The whole Island chain is highly actively volcanic with regular eruptions that quite frequently disrupt air traffic. Bali is well watered, volcanic, fertile and very warm year round, with seasons defined by the amount of rain.

Getting about

This article contains a series of recollections from my childhood growing up in Thornleigh; on the outskirts of Sydney Australia in the 1950s. My parents emigrated to Australia in 1948 when I was not quite three years old and my brother was a babe in arms.
 

Carbon Capture and Storage

(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.
