Hydroelectricity

 

Hydro-electricity is presently the largest contributor to renewable energy worldwide; in Australia and particularly in NSW.

 

Hydro-electricity also is more desirable than wind generation because of a higher capacity factor and ability to produce power on demand.

 

But hydro-electricity is resource constrained as it is difficult to build new dams in the developed countries that are presently heavy fossil fuel consumers.

Dams flood private property and/or National parks and have many self-interested and environmentally concerned opponents.  Hydro-electric schemes interfere with natural river flows and related wildlife, particularly when they involve extensive inundation.  It has become politically very difficult to construct new dams in Australia, even when the potential energy resource is significant. 

Nevertheless in developing countries like China, India and Vietnam there are large hydro-electricity resources that remain unexploited.

Travel

USA - middle bits

 

 

 

 

 

In September and October 2017 Wendy and I took another trip to the United States where we wanted to see some of the 'middle bits'.  Travel notes from earlier visits to the East coast and West Coast can also be found on this website.

For over six weeks we travelled through a dozen states and stayed for a night or more in 20 different cities, towns or locations. This involved six domestic flights for the longer legs; five car hires and many thousands of miles of driving on America's excellent National Highways and in between on many not so excellent local roads and streets.

We had decided to start in Chicago and 'head on down south' to New Orleans via: Tennessee; Georgia; Louisiana; and South Carolina. From there we would head west to: Texas; New Mexico; Arizona; Utah and Nevada; then to Los Angeles and home.  That's only a dozen states - so there are still lots of 'middle bits' left to be seen.

During the trip, disaster, in the form of three hurricanes and a mass shooting, seemed to precede us by a couple of days.

The United States is a fascinating country that has so much history, culture and language in common with us that it's extremely accessible. So these notes have turned out to be long and could easily have been much longer.

The new James Bond

 

 

It was raining in the mountains on Easter Saturday.

We'd decided to take a couple of days break in the Blue Mountains and do some walking. But on Saturday it poured.  In the morning we walked two kilometres from Katoomba to more up-market and trendy Leura for morning coffee and got very wet.

After a train journey to Mount Victoria and back to dry out and then lunch in the Irish Pub, with a Cider and Guinness, we decided against another soaking and explored the Katoomba antique stores and bookshops instead.  In one I found and bought an unread James Bond book.  But not by the real Ian Fleming. 

Ian Fleming died in 1964 at the young age of fifty-six and I'd read all his so I knew 'Devil May Care' was new.  This one is by Sebastian Faulks, known for his novel Birdsong, 'writing as Ian Fleming' in 2008.

Tragedy in Norway

 

 

The extraordinary tragedy in Norway points yet again to the dangers of extremism in any religion. 

I find it hard to comprehend that anyone can hold their religious beliefs so strongly that they are driven to carefully plan then systematically kill others.  Yet it seems to happen all to often.

The Norwegian murderer, Anders Behring Breivik, reportedly quotes Sydney's Cardinal Pell, John Howard and Peter Costello in his manifesto.   Breivik apparently sees himself as a Christian Knight on a renewed Crusade to stem the influx of Muslims to Europe; and to Norway in particular.
