In the late seventies I lived and worked in New York. My job took me all around the United States and Canada. So I like to go back occasionally; the last time being a couple of years ago with my soon to be wife Wendy. She had never been to New York so I worked up an itinerary to show her the highlights in just a few days. We also decided to drive to Washington DC and Boston.

As Tim Minchin sings in White Wine in the Sun [turn on your sound...] Christmas is a time for family. This year our family is one bigger. I have a new grandchild, Tilda Charlotte, in Germany. So the lyrics:
| And if my baby girl When you're twenty-one or thirty-one And Christmas comes around And you find yourself nine thousand miles from home You'll know what ever comes Your brothers and sisters and me and your mum Will be waiting for you in the sun When Christmas comes Your brothers and sisters, your aunts and your uncles Your grandparents, cousins and me and your mum We'll be waiting for you in the sun Drinking white wine in the sun Darling, whenever you come We'll be waiting for you in the sun Drinking white wine in the sun Waiting for you in the sun Darling, when Christmas comes We'll be waiting for you in the sun Waiting |
have a special meaning this year: I really like Christmas - It's sentimental, I know.

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.
