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

Darwin after Europe

 

 

On our return from Europe we spent a few days in Darwin and its surrounds.  We had a strong sense of re-engagement with Australia and found ourselves saying things like: 'isn't this nice'.

We were also able to catch up with some of our extended family. 

Julia's sister Anneke was there, working on the forthcoming Darwin Festival.  Wendy's cousin Gary and his partner Son live on an off-grid property, collecting their own water and solar electricity, about 120 km out of town. 

We went to the Mindl markets with Anneke and her friend Chris; and drove out to see Gary, in our hire-car, who showed us around Dundee Beach in his more robust vehicle. Son demonstrated her excellent cooking skills.

The Greatest Aviation Mystery of All Time

 

 

The search for Malaysia Airlines Flight 370 was finally called off in the first week of June 2018.

The flight's disappearance on the morning of 8 March 2014 has been described as the greatest aviation mystery of all time, surpassing the disappearance of Amelia Earhart in 1937.  Whether or no it now holds that record, the fruitless four year search for the missing plane is certainly the most costly in aviation history and MH370 has already spawned more conspiracy theories than the assassination of JFK; the disappearance of Australian PM Harold Holt; and the death of the former Princess Diana of Wales; combined.

Manufacturing in Australia

Originally written in August 2011 - it might have been yesterday - so little has changed.

 

 

Manufacturing viability is back in the news.

The loss of manufacturing jobs in the steel industry has been a rallying point for unions and employers' groups. The trigger was the announcement of the closure of the No 6 blast furnace at the BlueScope plant at Port Kembla.  This furnace is well into its present campaign and would have eventually required a very costly reline to keep operating.  The company says the loss of export sales does not justify its continued operation. The  remaining No 5 blast furnace underwent a major reline in 2009.  The immediate impact of the closure will be a halving of iron production; and correspondingly of downstream steel manufacture. BlueScope will also close the aging strip-rolling facility at Western Port in Victoria, originally designed to meet the automotive demand in Victoria and South Australia.

800 jobs will go at Port Kembla, 200 at Western Port and another 400 from local contractors.  The other Australian steelmaker OneSteel also recently announced a workforce reduction of 400 jobs.

This announcement has reignited the 20th Century free trade versus protectionist economic and political debate. Labor backbenchers and the Greens want a Parliamentary enquiry. The Prime Minister who reportedly initially agreed has now, perhaps smelling trouble, demurred.
