Armenia

 


Akhtala

Our first stop after crossing the border was the fortified Akhtala Byzantine Monastery, known for its 13th Century artistic frescoes. 

It's well positioned for defence and the site has been in use since the Bronze Age (13th century BCE), the derivation of the name 'Akhtala' being 'copper mine'.  The main gate and part of the wall remains but outlying buildings and other defences are in ruins.

It's said that when Timur (Tamerlane) arrived here he was admiring the church alone when he heard the sound of a baby.  He decided that the cry had come from the painting of the Virgin and Child on the dome above the alter. So he ordered their beheading. The story says that the cry had come from a real baby hidden from the invaders with its mother and others in the space behind the alter. 

We had fun speculating how his troops went about fulfilling Timur's order and decided it they must have used a large projectile, perhaps fired from an early cannon, a century before the Ottoman and Arabic 'Gunpowder Empires' - where cannon were first used in battle. 

Timur was technologically adept and highly intelligent, outsmarting the best of his opponents. He'd moved water courses to hamper opposing armies and used fire-camels against war elephants so why not? Read more...

Fortunately, despite a propensity for levelling entire cities and mercilessly slaughtering their inhabitants, Timur was quite intellectual and eclectic in his interests, frequently sparing structures he liked. By his lights a civilised man. So the church got off well - it's still standing.

Focussed damage to behead an image of the Virgin and Child - attributed Tamerlane
It looks as if quite accurately shot from below - was it done with a projectile? Gunpowder?

That Armenia is not as well off as Georgia was immediately apparent from the state of the regional roads the peoples' houses and the ruined industrial infrastructure.  Dozens of large industrial sites lie abandoned rusting and crumbling away.  Our guide told us that when the Soviet Union collapsed Armenia was particularly hard hit and as we learned in Azerbaijan, came under almost immediate attack - or was it the other way around?   Industry collapsed workers lost their jobs, the Russians who had provided local government and technical knowhow departed and social infrastructure and social security collapsed.  People in the cities starved. It took some time for competent government to be re-established.

There seemed to be endless abandoned industrial buildings some of them old copper smelters
In places the regional roads are so bad that we were reduced to walking pace - dodging potholes

 

In particular the electricity failed when the Russian maintained Nuclear Power Plant was shut down. This was built without secondary containment around the reactors, like Chernobyl.  After Chernobyl even the Russians were having second thoughts.  And this one is in an earthquake zone.  Yet the impact of its closure was so dire that it was reopened.   One reactor is still running.  Checking this out on-line I learned that: 

The Armenian Nuclear Power Plant, also known as the Metsamor Nuclear Power Plant, is located 36 kilometres west of Yerevan. Two model V-230 reactors, each of 407.5 MWe gross (376 MWe net), were built at Metsamor on solid basalt and supplied power from 1976 and 1980 respectively. Design operating lifetime was 30 years... One of these is still running. The operating licence has been extended to 2021. In September 2013 Russia announced an agreement to undertake works to extend the operating lifetime of the plant by ten years, and in May 2014 Russia agreed to provide $300 million for upgrading the plant to enable lifetime extension to 2026.  It has survived one major earthquake without damage.  The combination of design and location of Metsamor has been claimed to make it among the most dangerous nuclear plants in the world.

The plan, that, as an advocate of nuclear power in place of fossil fuel, I applaud, is to replace it with a safe, modern plant. Given the decaying state of Soviet era infrastructure in the country at large we can only hope that they are speedy about it.

Argentina & Uruguay

 

 

In October 2011 our little group: Sonia, Craig, Wendy and Richard visited Argentina. We spent two periods of time in Buenos Aires; at the start and at the end of our trip; and we two nights at the Iguassu Falls.

Australia's Hydrogen Economy

 

 

  

As anyone who has followed my website knows, I'm not a fan of using 'Green Hydrogen' (created by the electrolysis of water - using electricity) to generate electricity. 

I've nothing against hydrogen. It's the most abundant element in the universe. And I'm very fond of water (hydrogen oxide or more pedantically: dihydrogen monoxide). It's just that there is seldom a sensible justification for wasting most of one's electrical energy by converting it to hydrogen and then back to electricity again. 

I've made the argument against the electrolysis (green) route several times since launching this website fifteen years ago; largely to deaf ears.

The exception made in the main article (linked below) is where a generator has a periodic large unusable surpluses in an environment unsuitable for batteries. In the past various solutions have been attempted like heat storage in molten salt. But where there is a plentiful fresh water supply, producing hydrogen for later electricity generation is another option.  Also see: How does electricity work? - Approaches to Electricity Storage

Two of these conditions apply in South Australia that frequently has excess electricity (see the proportion of non-hydro renewables chart below). The State Government, with unspecified encouragement from the Prime Minister and the Commonwealth, has offered A$593m to a private consortium to build a 200MW, 100t hydrogen storage at Whyalla.  Yet, the State already has some very large batteries, with which this facility is unlikely to be able to compete commercially.  Time will tell.

We all die of something.

After 70 it's less likely to be as a result of risky behaviour or suicide and more likely to be heart disease followed by a stroke or cancer. Unfortunately as we age, like a horse in a race coming up from behind, dementia begins to take a larger toll and pulmonary disease sees off many of the remainder. Heart failure is probably the least troublesome choice, if you had one, or suicide.

In 2020 COVID-19 has become a significant killer overseas but in Australia less than a thousand died and the risk from influenza, pneumonia and lower respiratory conditions had also fallen as there was less respiratory infection due to pandemic precautions and increased influenza immunisation. So overall, in Australia in 2020, deaths were below the annual norm.  Yet 2021 will bring a new story and we've already had a new COVID-19 hotspot closing borders again right before Christmas*.

So what will kill me?

Some years back, in October 2016, at the age of 71, my aorta began to show it's age and I dropped into the repair shop where a new heart valve - a pericardial bio-prosthesis - was fitted. See The Meaning of Death elsewhere on this website. This has reduced my chances of heart failure so now I need to fear cancer; and later, dementia.
