Schisma Eloundas

 

We reached Crete by air in the afternoon, and, after picking up the car, drove the 70km to Schisma Eloundas and the Elounda Heights hotel.  As suggested by the name, the Hotel is up a steep hillside and has a great view. But the roads are not great.

The most direct approach road provided me with some driving challenges in an unfamiliar manual car car. How do you do a hill start on a narrow, very steep, slippery road, without a conventional hand-break (it had an electric toggle)?  It was a six speed box, with the gear stick on the wrong side (of course) and the reverse in the wrong place.  Obviously, I finally figured it out, with couple of stalls and some wheel spinning - we aren't still there.  Fortunately, the longer way up was easier - or was I just getting used to the car?  Another little driving adventure.

Agios Nikolaos

 

From here we were able to make a day trip to Agios Nikolaos, a rather overhyped resort town.  Yet it's home to the quite new Archaeological Museum of Agios Nikolaos housing an amazing collection of finely worked Minoan: ceramic, gold and bronze objects dated back as far as 3000 BCE.  Well worth the visit

 

The town of Agios Nikolaos boasts a famous, 'bottomless', lake, off the harbour, surrounded, on three sides, by high rock cliffs.
The claim that the lake is bottomless is, obviously, ridiculous but it's apparently quite deep
It is also home to the Archaeological Museum of Agios Nikolaos - that is very worthwhile

 

Earlier in this trip, we visited the ruins of Akrotiri, (see above) an outpost of the Minoan civilisation that evolved and flourished for nearly two millennia, between 3000 and 1100 BCE.  Crete was the principal centre of this civilisation

Thus Crete possessed perhaps, the most advanced society humans had yet evolved, based on their mastery of kiln fired pottery, the essential pre-cursor to the metallic furnace with temperatures high enough to melt: tin (232o C); bronze (913o C) silver (979o C); gold(1063o C); and copper (1084o C).  You can see some 4,000-year-old cast bronze axe heads in the photo above.

Although cast iron was being manufactured in China in the 5th century BCE and poured into molds to make ploughshares and pots as well as weapons and pagodas, it was not until Chinese blast furnace technology came west, probably thanks to the Muslim traders and the silk road, that temperatures sufficiently high to melt iron (1127 – 1204o C) became possible in Europe.

In Europe, for another fifteen-hundred years, ironmaking still employed a Bloomery.
This slowly reduced the ore, using carbon monoxide, into soft sponge-iron, that was then forged into shape.

It would not be until the Enlightenment, beginning at the end of 17th century BCE, that technology became divorced from religion and rapid advances began to be to be made. Not just in metallurgy but notably in medicine, chemistry and electricity. No longer would a god (or gods) be the explanation for world events and processes and thus: the success; or failure; or continuation; of a physical process. Vulcan and his fellow imaginary gods were out; testable evidence was in.

Unshackled from superstition, scientific progress leapt ahead.  For example, the Eiffel Tower (completed in1889) is wrought iron (made in a puddling furnace) just 50 years later that was old-hat.  The new railways needed steel so, soon the 19th century Bessemer and puddling processes would be superseded by open-hearth steelmaking so that 20th century structures, like the Sydney Harbour Bridge and the Empire State Building, became possible. As metallurgy became increasingly scientific (it was historically an arcane craft handed down from master to apprentice) progress became rapid and the list of previously impossible metals like: aluminium; titanium and tungsten became commonplace. Human capabilities expanded. Soon we could fly around the world and visit the moon.

In the 21st century new materials are added to our civilisation daily. Now, thanks to rockets and satellites, we can make video calls to our family in Germany or France for next to no cost.  All civilisation is based on how their people harness technology, from metallurgy to agriculture.

It was upon their knowledge of seafaring, ceramics and metallurgy that Minoan civilisation was built.  Yet, shackled to progress-resisting-traditions advances were slow. So, after persisting for well over a thousand years, it was a failure to keep up with developments in technology that contributed to that civilisation's demise. Around 1000 BCE under new gods, Crete was conquered by the Mycenaean Greeks who ruled briefly, until themselves engulphed by the chaos of the 'Postpalatial Bronze Age' (Early Iron Age). 

In due course, as already discussed above, the more innovative Romans would prevail in Greece and Crete, as elsewhere in the Mediterranean. They would evolve, in the Common Era, into Byzantines, before their trinitarian God would become one again, under the Ottomans, before returning to power in the 19th century.

 

Kritsa

 

Before the steam engine came the water-wheel and in the absence of a river, the wind-mill.  On our way back to Schisma Eloundas we stopped at the pretty town of Kritsa that, mysteriously, has the remains of a grain-mill in the town square and quite nice milkshakes.

 

Stripped down windmill at Kritsa Village, Crete and milkshake hoff.

 

The Palace of Knossos

 

The Palace of Knossos on once mighty Crete the principal centre of the Minoan civilisation circa 1700 BCE long before the rise of Greece, then the Romans and then the Christians.

The ruins were excavated by Arthur Evans in the 1920s and 30's who undertook to reconstruct elements of the Palace. This is not kosher but has proven hugely popular. Hence the colourful pillars, based on frescoes actually found. Reconstruction does make it more interesting as the crowds attest.

This is my second visit here.  I notice that several painted features are undimmed from my earlier photographs nearly 40 years ago. So, some repainting must be going on. And the walkways are new.

Heraklion Archaeological Museum

 

This is not in chronological order. I came here on our last day in Crete. Yet, the Heraklion Archaeological Museum, contains many of the treasures found at Knossos. So, I've bought those pictures forward. 

The museum is mostly about the Minoans but has Roman and Greek objects too. It displays amazing metallurgy. And intricate craft skills. Mostly over 3,000 years old.

Rethimno

 

After quite a long drive that included a very nice lunch at a restaurant, found by serendipity, at Gazi, we reached our next hotel in Rethimno. The most obvious feature of the Rethimno is the huge Venetian fortress commanding the seashore. It once contained many structures but is now largely empty: piles of rubble and rough grass and trees. Yet the defensive walls are in tact.

Chania

 

After Rethimno we continued west to Chania, an hour's drive along picturesque coastal clifftops.

As google tells us: Chania is known for its 14th-century Venetian harbor, narrow streets and waterfront restaurants. At the harbor entrance is a 16th-century lighthouse with Venetian, Egyptian and Ottoman influences.

We had accommodation in the old town, that is closed to traffic. We had a short walk up from the nearest parking area but after an initial lucky find we left town for a day trip and then had to park some distance away.

Our accommodation was in the old town - adequate and well located

 

With Chania as our base, the following day we drove over winding, mountainous roads, to the resort town of Palaiochora, on the south coast, passing through several towns, some no more than one or two roadside buildings. 

 

Voukolies

 

More substantial than most was Voukolies, where the traditional Greek separation of the sexes was in evidence: several coffee shops populated entirely by men, while the women supervised the children playing in the park.

Kandanos

 

This changed when we got to Kandanos, where the coffee shop proprietor was an Australian woman from Melbourne, who married a Greek man she met while on holiday here. Two adult sons assist her. The town has an interesting history. In ancient times a Roman mining town, it was a centre of resistance during WW2 and was razed by the Germans, in retaliation for the killing of 25 German soldiers - 'never to be rebuilt'. Needless to say, it was promptly rebuilt, upon Germany's defeat. The large church, in particular.

Palaiochora

 

In Palaiochora evidence of Minoan occupation is slight but the ruins of a Venetian fortress dominate the point.

Archaeological Museum of Chania


The Archaeological Museum of Chania is in the historic suburb of Chalepa, housed in a modern 'iconic building constituting a landmark for the whole city'...  'presenting the wealth of archaeological material that has been retrieved from the periphery of Chania through the course of time'.

It is indeed a fine, modern museum, a 35min walk from the old town (not unequivocally recommended). The cafeteria has a great view, looking back the way we walked.

Again, it maps the local history, from the Minoan to Mycenae/Greek; the Roman/Byzantine; to Venetian and Turkish/Ottoman; and back to Christian.

Nearby there are the remains of a two storey Minoan house 220sq metres on the ground floor. With plumbing, or was it claying? They were masters of terracotta. Of course, by then they also smelted gold, lead and bronze/copper/tin but not iron, that requires much higher temperatures than they could achieve. Copper ore is found on Crete but the other ores must have been traded. Currency had not yet been invented, so they had an elaborate barter system, involving clay seals to establish value. As I mentioned earlier, writing was in Linear A, script as yet undecipherable. But AI might do it.

There was a big swell on our last morning in Chania with a full surf beyond the lighthouse.
Later the surf on the beach, as we drove along the coast, back to Heraklion was also very respectable.

 

Heraklion

 

In Heraklion and I visited the Heraklion Archaeological Museum, as described above after Knossos, while Wendy explored downtown.

The following day we returned the car and flew to Thessaloniki (Thessalonica).

Bridge over the River Kwai

 

 

In 1957-58 the film ‘The Bridge on the River Kwai‘ was ground breaking.  It was remarkable for being mainly shot on location (in Ceylon not Thailand) rather than in a studio and for involving the construction and demolition of a real, fully functioning rail bridge.   It's still regarded by many as one of the finest movies ever made. 

One of the things a tourist to Bangkok is encouraged to do is to take a day trip to the actual bridge.

Chappaquiddick

 

 

 

'Teddy, Teddy, I'm pregnant!
Never mind Mary Jo. We'll cross that bridge when we come to it.'

 


So went the joke created by my friend Brian in 1969 - at least he was certainly the originator among our circle of friends.

The joke was amusingly current throughout 1970's as Teddy Kennedy again stood for the Senate and made later headlines. It got a another good run a decade later when Teddy decided to run against the incumbent President Jimmy Carter for the Democratic Presidential nomination.

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’."

Read more: Electricity Pricing - The cost of energy sources

 

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."

Read more: Australia's carbon 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.
