For the first time in weeks Angela had slept well and as dawn approached she anticipated her new career as a Movie Director.
When I was a boy, Turkey was mysterious and exotic place to me. They were not Christians there; they ate strange food; and wore strange clothes. There was something called a ‘bazaar’ where white women were kidnapped and sold into white slavery. Bob Hope and Bing Crosby, or was it Errol Flynn, got into all sorts of trouble there with blood thirsty men with curved swords. There was a song on the radio that reminded me over and over again that ‘It’s Istanbul not Constantinople Now’, sung by The Four Lads, possibly the first ‘boy band’.
'I was recently restored to life after being dead for several hours'
The truth of this statement depends on the changing and surprisingly imprecise meaning of the word: 'dead'.
Until the middle of last century a medical person may well have declared me dead. I was definitely dead by the rules of the day. I lacked most of the essential 'vital signs' of a living person and the technology that sustained me in their absence was not yet perfected.
I was no longer breathing; I had no heartbeat; I was limp and unconscious; and I failed to respond to stimuli, like being cut open (as in a post mortem examination) and having my heart sliced into. Until the middle of the 20th century the next course would have been to call an undertaker; say some comforting words then dispose of my corpse: perhaps at sea if I was travelling (that might be nice); or it in a box in the ground; or by feeding my low-ash coffin into a furnace then collect the dust to deposit or scatter somewhere.
But today we set little store by a pulse or breathing as arbiters of life. No more listening for a heartbeat or holding a feather to the nose. Now we need to know about the state of the brain and central nervous system. According to the BMA: '{death} is generally taken to mean the irreversible loss of capacity for consciousness combined with the irreversible loss of capacity to breathe'. In other words, returning from death depends on the potential of our brain and central nervous system to recover from whatever trauma or disease assails us.
Carbon Sequestration Source: Wikimedia Commons
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.
