Geothermal power is competitive with coal and less expensive than wind when the resource is very near to the surface; for example in the ‘pacific rim of fire’ countries. Many plants already exist around the world in volcanic areas. Unlike wind or solar geothermal power is continuous and ‘base load’. But the easily exploited resource is geographically limited and its contribution to total energy consumed worldwide is negligible compared to that of hydro and wind.

Deep geothermal is more widely distributed and is being explored in several locations in Australia but at the present time substantial technical issues have not been fully resolved and the capital cost of extraction is likely to be very high (leading to a high carbon footprint and very high cost per kWh).

Nevertheless it is hoped that geothermal power could compliment wind or solar as the REC value climbs and/or an ETS comes into effect.

India and Nepal

Introduction

In October 2012 we travelled to Nepal and South India. We had been to North India a couple of years ago and wanted to see more of this fascinating country; that will be the most populous country in the World within the next two decades.

In many ways India is like a federation of several countries; so different is one region from another. For my commentary on our trip to Northern India in 2009 Read here...

For that matter Nepal could well be part of India as it differs less from some regions of India than do some actual regions of India.

These regional differences range from climate and ethnicity to economic wellbeing and religious practice. Although poverty, resulting from inadequate education and over-population is commonplace throughout the sub-continent, it is much worse in some regions than in others.

The Cloud

Chapter 1 - The Party

This morning Miranda had an inspiration - real candles! We'll have real candles - made from real beeswax and scented with real bergamot for my final party as a celebration of my life and my death. This brief candle indeed!

In other circumstances she would be turning 60 next birthday. With her classic figure, clear skin and dark lustrous hair, by the standards of last century she looks half her age, barely thirty, the result of a good education; modern scientific and medical knowledge; a healthy diet and lifestyle and the elimination of inherited diseases before the ban on such medical interventions.

It's ironical that except as a result of accidents, skiing, rock climbing, paragliding and so on, Miranda's seldom had need of a doctor. She's a beneficiary of (once legal) genetic selection and unlike some people she's never had to resort to an illegal back-yard operation to extend her life.

A modern fairytale - in a Parallel Universe

I've dusted off this little satirical parable that I wrote in response to the The Garnaut Climate Change Review (2008). It's not entirely fair but then satire never is.

In a parallel universe, in 1920† Sidney, the place where Sydney is in ours, had need of a harbour crossing.

An engineer, Dr Roadfield, was engaged to look at the practicalities; including the geology and geography and required property resumptions, in the context of contemporary technical options.

After considering the options he reported that most advanced countries solve the harbour crossing problem with a bridge. He proposed that they make the decision to have a bridge; call for tenders for an engineering design; raise the finance; and build it. We'll call it the 'Sidney Harbour Bridge' he said; then less modestly: 'and the new crossing will be called the Roadfield Highway'.
