In Shenzhen we habitually stay at the Intercontinental at Overseas China Town (OCT) as it's a five star hotel; within our budget; right on the Metro; and thus provides easy access to markets; art galleries; and even a theme park. Directly across the highway (access via the metro tunnel) there is a large more-natural woodland-park as well as a pleasant village and shopping precinct, with restaurants and coffee shops.  The hotel has well-appointed public spaces including several restaurants and conference rooms and is very comfortable.  The breakfast, in particular, is vast, catering to every taste.  

This is the third time we've stayed here. 

 

After arriving and settling in we went across the road to Walmart for a light lunch and to buy some Australian wine (yes, it was back). 

Such was our travail that we then had to relax at a pleasant coffee shop with charming server. We'd walked another 12 km today.

I spent the morning in the park and exploring the town - more coffee. 

This is just a small area in this largely wooded park. Very nice and very needed, given all the high-rise apartments nearby.

 

 

Around the local park. OTC, Shenzhen, China.

Hence the feedback - the only sound my camera recorded.

 

Despite rumours to the contrary, China's building boom is still in full swing here. The building with the palm trees is new and the tall building in the distance is the Ping An Finance Centre, fifth-tallest building in the World (115 stories - 599 m).

 

Unlike last time, once out of the hotel, almost no one here speaks English. Can they have forgotten? No. It's a young and confident new generation. China is now a world power. It's the same arrogance that English speakers once had. 'If they don't understand you shout,' an American once told me.  At least the Chinese remain polite.


Last night in China.
Tomorrow it will be back on the Metro to the border; then on to the HK Metro to the city; to catch a taxi to the cruise terminal and board the ship. 

We went back over the highway to a restaurant that I'd discovered earlier in the day. Where we ordered whole roast duck and a salad.

 



Fortunately the menu had pictures, as there was no translation and we had no internet. Wifi was a couple of Chinese characters??? 

We'd bought the wine at the supermarket ($A 14) and tried to ask if BYO was OK. It was farcical trying to use sign language to ask that. But then they produced both wine glasses and ice. No charge.

Why can't these foreigners speak Mandarin? Or read or write?

Needless to say, the meal was excellent. It was also inexpensive and a fraction of the price of a similar evening meal at the Intercontinental, across the road. Or in Australia.

The restaurant is quite large and there were numerous young couples, some with children, enjoying each other's company and the atmosphere was very convivial.  Have you ever noticed that people laugh the same in any language?

Berlin

 

 

 

I'm a bit daunted writing about Berlin.  

Somehow I'm happy to put down a couple of paragraphs about many other cities and towns I've visited but there are some that seem too complicated for a quick 'off the cuff' summary.  Sydney of course, my present home town, and past home towns like New York and London.  I know just too much about them for a glib first impression.

Although I've never lived there I've visited Berlin on several occasions for periods of up to a couple of weeks.  I also have family there and have been introduced to their circle of friends.

So I decided that I can't really sum Berlin up, any more that I can sum up London or New York, so instead I should pick some aspects of uniqueness to highlight.

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.

Opinions and Philosophy

Issues Arising from the Greenhouse Hypothesis

This paper was first written in 1990 - nearly 30 years ago - yet little has changed.

Except of course, that a lot of politicians and bureaucrats have put in a lot of air miles and stayed in some excellent hotels in interesting places around the world like Kyoto, Amsterdam and Cancun. 

In the interim technology has come to our aid.  Wind turbines, dismissed here, have become larger and much more economic as have PV solar panels.  Renewable energy options are discussed in more detail elsewhere on this website.

 


 

Climate Change

Issues Arising from the Greenhouse Hypothesis

 

Climate change has wide ranging implications for the World, ranging from its impacts on agriculture (through drought, floods, water availability, land degradation and carbon credits) mining (by limiting markets for coal and minerals processing) manufacturing and transport (through energy costs) to property damage resulting from storms.  The issues are complex, ranging from disputes about the impact of human activities on global warming, to arguments about what should be done and the consequences of the various actions proposed.  The following paper explores some of the issues and their potential impact.
