For my commentary on our trip to Northern India in 2009 Read here...
In June 2018 we travelled to China before joining an organised tour in Central Asia that, except for a sojourn in the mountains of Tajikistan, followed in the footsteps of Marco Polo along the Great Silk Road.

Marvellous. Emily, my eldest daughter, has given birth to my first natural Grandchild (I have three step-grandchildren). She and Guido have named him Leander. Mother and child are well.
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.
