Following our Japan trip in May 2017 we all returned to Hong Kong, after which Craig and Sonia headed home and Wendy and I headed to Shenzhen in China. 

I have mentioned both these locations as a result of previous travels.  They form what is effectively a single conurbation divided by the Hong Kong/Mainland border and this line also divides the population economically and in terms of population density.

These days there is a great deal of two way traffic between the two.  It's very easy if one has the appropriate passes; and just a little less so for foreign tourists like us.  Australians don't need a visa to Hong Kong but do need one to go into China unless flying through and stopping at certain locations for less than 72 hours.  Getting a visa requires a visit to the Chinese consulate at home or sitting around in a reception room on the Hong Kong side of the border, for about an hour in a ticket-queue, waiting for a (less expensive) temporary visa to be issued.

With documents in hand it's no more difficult than walking from one metro platform to the next, a five minute walk, interrupted in this case by queues at the immigration desks.  Both metros are world class and very similar, with the metro on the Chinese side a little more modern. It's also considerably less expensive. From here you can also take a very fast train to Guangzhou (see our recent visit there on this website) and from there to other major cities in China. 

There are several pictures taken on the metro in Guangzhou in that album. Both the Shenzhen Metro and the Hong Kong MTR are similar from a commuter's standpoint.  Everything is very modern with: good lighting and air-conditioning; platform glass barriers; lots of shiny metallic surfaces; lifts; and escalators. 

 

The Guangzhou Metro (with 186 stations) is technically very similar those larger networks in Shanghai (364 stations)
and Shenzhen (with 199 stations).  Hong Kong MTR has 93 similar rail and 68 integrated light rail (tram) stops

 

More about Trains - for those interested

All China's trains use 'Standard Guage', unlike Australia's farcical differences between States.  Most Mainland metros use 1,500 V DC, as do the majority of Hong Kong MTR tracks, while the older but also huge Beijing Subway (with 345 stations  - growing steadily), employs only half that voltage, like the MTR light rail. 750V is safer in public streets but puts a limit on top speed, like Melbourne's trams on only 600V DC. 

Thus the newest and longest MTR lines, like the partially completed Hung Hom line, employ 25,000 V AC, in harmony with China Railway High-speed (CHR) services.

These were originally based on Japan's Shinkansen  (see Japan) and initially the train sets were imported from Japan but in 2004 public outrage over using Japanese manufactured rolling stock led to increased domestic production, in turn to independent technological development (still in cooperation with Kawasaki Heavy Industries).  Now the 'China Standardized EMU' train-set, introduced in 2016, has a regular operational speed of 350 km/h (217 mph) but the CRH380BL train-set has attained a test speed of 487.3 km/h (302.8 mph), a considerable improvement on the Japanese train-sets.

With eight horizontal and eight vertical lines, totalling 12,000 km, forming a rough grid over the map of China and regular operating speeds of up to 400km/h China's is by far the most extensive and advanced high speed rail network in the world.

Hawaii

 

 

 

 

 

When we talked of going to Hawaii for a couple of weeks in February 2018 several of our friends enthusiastically recommended it. To many of them it's a nice place to go on holidays - a little further to go than Bali but with a nicer climate, better beaches and better shopping - with bargains to be had at the designer outlets.

 


Waikiki

 

To nearly one and a half million racially diverse Hawaiians it's home.

 

 


Downtown Hilo

 

To other Americans it's the newest State, the only one thousands of miles from the North American Continent, and the one that's more exotic than Florida.

Love in the time of Coronavirus

 

 

 

 

Gabriel García Márquez's novel Love in the Time of Cholera lies abandoned on my bookshelf.  I lost patience with his mysticism - or maybe it was One Hundred Years of Solitude that drove me bananas?  Yet like Albert Camus' The Plague it's a title that seems fit for the times.  In some ways writing anything just now feels like a similar undertaking.

My next travel diary on this website was to have been about the wonders of Cruising - expanding on my photo diary of our recent trip to Papua New Guinea.

 


Cruising to PNG - click on the image to see more

 

Somehow that project now seems a little like advocating passing time with that entertaining game: Russian Roulette. A trip on Corona Cruise Lines perhaps?

In the meantime I've been drawn into several Facebook discussions about the 1918-20 Spanish Influenza pandemic.

After a little consideration I've concluded that it's a bad time to be a National or State leader as they will soon be forced to make the unenviable choice between the Scylla and Charybdis that I end this essay with.

On a brighter note, I've discovered that the economy can be expected to bounce back invigorated. We have all heard of the Roaring Twenties

So the cruise industry, can take heart, because the most remarkable thing about Spanish Influenza pandemic was just how quickly people got over it after it passed.

Renewable Electricity

 

 

As the energy is essentially free, renewable electricity costs, like those of nuclear electricity, are almost entirely dependent on the up-front construction costs and the method of financing these.  Minimising the initial investment, relative to the expected energy yield, is critical to commercial viability.  But revenue is also dependent on when, and where, the energy can be delivered to meet the demand patterns of energy consumers.

For example, if it requires four times the capital investment in equipment to extract one megawatt hour (1 MWh) of useable electricity from sunlight, as compared to extracting it from wind, engineers need to find ways of quartering the cost of solar capture and conversion equipment; or increasing the energy converted to electricity fourfold; to make solar directly competitive.
