Geothermal

 

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.

Spain and Portugal

 

 

Spain is in the news.

Spain has now become the fourth Eurozone country, after Greece, Ireland and Portugal, to get bailout funds in the growing crisis gripping the Euro.

Unemployment is high and services are being cut to reduce debt and bring budgets into balance.  Some economists doubt this is possible within the context of a single currency shared with Germany and France. There have been violent but futile street demonstrations.

Fiction, Recollections & News

Australia in the 1930s

 

 

These recollections are by Ross Smith, written when he was only 86 years old; the same young man who subsequently went to war in New Britain; as related elsewhere on this website [read more...].  We learn about the development of the skills that later saved his life and those of others in his platoon.  We also get a sense of what it was to be poor in pre-war Australia; and the continuity of that experience from the earlier convict and pioneering days from which our Australia grew.                   *

The demise of books and newspapers

 

 

Most commentators expect that traditional print media will be replaced in the very near future by electronic devices similar to the Kindle, pads and phones.  Some believe, as a consequence, that the very utility of traditional books and media will change irrevocably as our ability to appreciate them changes.  At least one of them is profoundly unsettled by this prospect; that he argues is already under way.
