Tbilisi (tbi-lisi)


 

Tbilisi is the capital of Georgia and like the country in general it is attractive and would be more so if there were less cars. By some coup of marketing there is a preponderance of Toyota Priuses (or is it Prii). 

The city has its origins in the 6th century battles for the Caucasus between the Persians (Iranians) who were at the time Zoroastrians and the Europeans who were Christian.  By tradition Tbilisi is said to have been founded by 32nd King of Iberia:  Vakhtang I Gorgasali (c. 447/49 – 502/22) a Christian allied to the Byzantine Empire (Romans), who also reorganised the Georgian Orthodox Church and set the religious foundations of the region.

Standing above the city is the Narikala Fortress which may predate the city and is said to have been an earlier Persian stronghold. Vakhtang I vanquished the Zoroastrians and extended the fortifications but a century later the Muslim Umayyads (Arabs) would arrive to assert their world view, in their turn, expanding the fortifications. 

These again proved to be insufficient when in 1121 the Christian King David IV would overcome them and drive the Arabs from the country, beginning Georgia's 'Golden Age'. 

Again the Narikala Fortress would be expanded and modernised. But in 1222 2,000 light cavalry of Genghis Khan arrived and decisively routed the larger Georgian army.  So the country fell to the Mongols. The Mongols were generally religiously tolerant, provided people were subservient and paid their taxes.  Thus Georgia remained Christian, though many churches and monasteries complained about their metaphysical observances being taxed.  In turn, the Mongols strengthened the Narikala Fortress that they named the 'Little Fort'.

Now Georgia was part of a properly managed Khanate people went about their business relatively unmolested. It would not last.

In 1346 the bubonic plague (the Black Death) arrived, wiping out an estimated half of the population, followed by the first Timurid invasion.  Timur (Tamerlane - 'The sword of Islam' see elsewhere on this website) sacked Tbilisi in 1386 occasioning more postbellum repairs to the fort. 

Despite Timur's repeated attacks in the cause of jihad, eight in total, often damaging or demolishing churches, Georgia remained stubbornly Christian and was eventually recognised by Timur as such.  His most bitter fights were with fellow Muslims. In the Elizabethan Christopher Marlowe's play: Tamburlaine the Great (c. 1587) he is depicted as becoming progressively anti-Muslim.

In the 15th century Tbilisi was the centre of further battles for dominance by a variety of kings and tyrants so that the fortress was repeatedly damaged and rebuilt. Today most of the fortifications we see are even more recent, dating from the Russian incursions, mentioned above, starting in the 16th and 17th centuries. In 1827 the fortress was again damaged not by war but (alternatively): by the explosion of Russian munitions; and/or by an earthquake; depending on who you ask.  As fire often accompanied an earthquake when lighting, cooking and heating involved open flames, and gunpowder can be set-off with a hammer or something heavy falling - an earthquake seems a likely culprit if munitions also exploded.

Tbilisi is surrounded by ravines, canyons and valleys.  The Old Town has long been renowned for its healing Sulphur Baths said to give relief to sufferers of various ailments, including skin conditions and arthritis.  It's a great place to bathe if you don't mind sharing with sufferers of scrofula, tinea or lupus.  But my hesitancy aside, for many centuries health cures have been a significant driver of international commerce and Tbilisi has long benefited from a stream of visitors wanting to take a dip in mineralised water.

A nearby bridge over the stream is covered in locks, symbolising endless love or maybe the institution of marriage.  One lay open in the water - make of that what you will.

As a result of the ebb and flow of conquerors Tbilisi (al-Tefelis) became a centre of trade between the Islamic world and northern Europe. So although Georgia is predominantly Christian there remains a smaller Muslim community in Tbilisi and the Sunnite Mosque has stood in Botanical Street since the 19th century.

Our travel notes told us:

'Acting as the fortress and residence of the Georgian tsars, it [Metekhi Church] often came under attack and was almost demolished during the Great Purge that took place across the Soviet Union in the 1930s.

Checking this out on-line I discovered that the Metekhi Church had ceased to function as a church back in the 17th century when the prominence, upon which the church stands, was fortified as a defensive citadel.  By the 19th century, under the Russians, the church building was being used as a barracks. In 1819 the citadel was removed and the church building was incorporated into a gaol. In 1938, at the end of Stalin's Great Purge (see below) the gaol, that had become infamous, was demolished, the church building alone surviving to become a theatre.  In the 1988 the Catholicos-Patriarch of All Georgia Ilia II successfully campaigned to restore the church to the Georgian Patriarchate.

Travel

Mexico

 

  In March 2025 Wendy and I flew from Sydney to Los Angeles (LAX) and caught a shuttle bus, south, to San Diego (old Town).

 After a couple of days in San Diego we joined an 11 day cruise to Mexico, aboard Holland America’s ‘Zaandam’.  

 This was our second trip to Mexico.

 We first visited Mexico on our way to Cuba in 2012. I didn’t write about the Mexico or California components of our trip back then because I didn’t want to detract from the Cuba story.

If you didn't see it at the time, follow this link: Cuba

 So, first, here are my recollections of that experience, mellowed by time, informed by hindsight.

Moby Dick

 

 

 

Several times past I've begun to read Moby Dick. It's one of the classic books I freely downloaded to my Kindle from 'Project Gutenberg'. Yet, each time, soon after reading: "Call me Ishmael" I put it down in frustration: at the flowery language and depressing imagery of the opening chapters. It's not Treasure Island.

Electricity Woes

 

Recently, the National Electricity Market in Eastern Australia had to be temporarily suspended due to a shortfall in generation.

Now, the new Federal Government, that came to power on a promise to substantially cut power bills, has had to concede, that instead, there will be substantial price increases.

In part, they are blaming the war in the Ukraine; the consequent sanctions against Russia; and Russian retaliation.

During the election campaign the Shadow Minister for Climate Change and Energy repeatedly asserted that the solution lay in increased wind and solar generated electricity, that he also repeatedly asserted were cheaper than fossil-fuel generated electricity. 

Yet, now the solution is said to lie in 'temporary' price caps on the spot-price of steaming coal and gas (mainly methane).  

An observer from another planet might ask: why the global demand for steaming coal and gas is still rising (and with it their price) when wind and solar are, allegedly, so much cheaper? 

Meanwhile, last July (2022) Wendy and I had occasion to visit the town of Rønne on the small Danish island of Bornholm. There on the quayside were a dozen huge wind-turbine nacelles.

As I had some spare time on my hands, I looked on-line and discovered that they were Vestas V174-9.5 MW units for installation off the coast of Germany, for either the Baltic Eagle or Arcadis Ost 1 project. I compared the published project costs with those of other large scale energy projects around the world.

You can read my analysis here (Europe 2022 - Part 1 - An Energetic Diversion). 

Suffice it to say, that wind-generated electricity is not price-competitive with modern fossil generated electricity - it's just a lot cleaner.

Most importantly: nor is off-shore wind anywhere near price-competitive with the latest nuclear generated electricity (on a dollar per unit of installed capacity basis), as nuclear power has a similar cost per Watt of capacity but doesn't require additional batteries or pump-storage to satisfy fluctuating demand.

The present situation on the east coast of Australia may (or may not) have been aggravated by the war in the Ukraine.  Yet, the short-fall was entirely predictable, over a decade ago, and  it will not go away when the war ends.

In anticipation, back in 2012, I called for a 'root and branch' reappraisal of the combined impact of the Renewable Energy Target scheme, in the context of the operations of the National Electricity Market (NEM):

 

2012

"The present government interventions in electricity markets, intended to move the industry from coal to renewable energy sources, are responsible for most of the rapidly rising cost of electricity in Australia.  These interventions have introduced unanticipated distortions and inefficiencies in the way that electricity is delivered.

Industry experts point to looming problems in supply and even higher price increases.

A 'root and branch' review of these mechanisms is urgently required to prevent ever increasing prices and to prevent further potentially crippling distortions."

I asserted that together these were making essential base load generators unprofitable and may lead to brownouts and blackouts in the future:

2012

"Now, in addition, rooftop photo-voltaic (PV) solar is beginning to add power to local distribution grids in mid-summer, when the market price is at its maximum and thermal stations have previously been assured of a profit.  Again the retailer pays for STC’s that subsidise the price of solar.

While again we might applaud the lowering of the peak market price and the reduction of peak grid currents at this time, we will not be so pleased if failure to invest in new generation capacity results in even higher prices; and future brownouts and blackouts.

While at first sight there appears to be a well established competitive generation market, the renewable energy targets and the associated certificates (paid for by our retailer and appearing in our bill) may be having an increasingly adverse effect on future investment decisions; with potentially disastrous outcomes ‘down the track’."

The article was written at a time when an ill-conceived Carbon Tax, that only targeted particular industries and in some cases individual businesses, was severely distorting the energy marketplace even further. 

A year earlier I had objected to the Gillard Government's short lived Carbon Tax on these grounds:

2011

"Well, the Gillard government has done it; they have announced the long awaited price on carbon...

Accusations of lying and broken promises aside, the problem of using a tax rather than the earlier proposed cap-and-trade mechanism is devising a means by which the revenue raised will be returned to stimulate investment in new non-carbon based energy.

Taxation always boils down to 'robbing Peter to pay Paul'. In this case the Government knows who Peter is but they apparently have no idea, or too many, about Paul.

It is the very definition of administrative inefficiency to rob Peter to pay Peter. Thus any tax that requires offsetting payments to those taxed is poorly designed; administratively cumbersome and likely to be extremely inefficient; a bad tax."

The Carbon Tax has gone but not the underlying problem remains: traditional coal fired power stations - upon which we will still need to rely for at least another decade - cannot remain viable as long as they are continually gazumped in the NEM by cross- subsidised renewable electricity generators.

This cross-subsidy, is in the form of Large-scale Generation Certificates (LGC's), paid for by electricity retailers (in other words: you). Each MWh of renewable energy supplied receives this cross-subsidy (effectively at the expense of other generators). It applies irrespective of the rapidly fluctuating (NEM) market price for that electricity (energy), that from time-to-time is very low or negative, due to ample wind or sunlight and low consumer demand.

By this means, renewable electricity, including rooftop solar, has been given a 'leg-up', in order to meet the Australian Government's Renewable Energy Targets.

When governments intervene in markets it always has consequences. Such an intervention maybe necessary in the long-term public interest, for example due to externalities, like the environment, or international responsibilities. Yet, then it is beholden on Government to put in place accompanying means of mitigating the inevitable negative consequences. 

In this case the negative consequences of Renewable Energy Targets on base-load electricity generation have been well known for well over a decade but nothing has been done in mitigation.

Possible mitigations might include:

  • an off-market base-load generation reservation and/or, perhaps;
  • ineligibility of all Renewable Energy Certificates (small and large scale) for energy supplied when supply exceeds demand.

Comprehensive modelling of these and other possible interventions, such as a targeted subsidy, is now essential to determine the best transition path to a secure electricity future.

A 'root and branch' review is long over-due.

If only...

'If onlys' are a bit pointless, yet I'll say it again: Had we embarked on building just three nuclear power-stations similar to the Cruas Nuclear Power Station in France, two or three decades ago (read more...), we could already be 'clean and green' and not in the predicament we now find ourselves in today. 

Instead, we find ourselves paying for Snowy 2.0 that will be: more expensive; more environmentally damaging; and totally inadequate to make a significant difference (see: Pumped-Storage Hydropower (PSH). Read more....

But that's all water over the dam now.
