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.

The Time Lord

 

 

 

For no apparent reason, the silver haired man ran from his companion, shook a tree branch, then ran back to continue their normal conversation. It was as if nothing had happened. The woman seemed to ignore his sudden departure and return.

Bruce had been stopped in peak hour traffic, in the leafy suburban street, and had noticed the couple walking towards him, engaged in good humoured argument or debate.  Unless this was some bizarre fit, as it seemed, the shaken tree branch must be to illustrate some point. But what could it be?

Just as the couple passed him, the lights up ahead changed and the traffic began to move again.

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.
