South Korea & China

March 2016

 

 

South Korea

 

 

I hadn't written up our trip to South Korea (in March 2016) but Google Pictures gratuitously put an album together from my Cloud library so I was motivated to add a few words and put it up on my Website.  Normally I would use selected images to illustrate observations about a place visited.  This is the other way about, with a lot of images that I may not have otherwise chosen.  It requires you to go to the link below if you want to see pictures. You may find some of the images interesting and want to by-pass others quickly. Your choice. In addition to the album, Google generated a short movie in an 8mm style - complete with dust flecks. You can see this by clicking the last frame, at the bottom of the album.

A few days in Seoul were followed by travels around the country, helpfully illustrated in the album by Google generated maps: a picture is worth a thousand words; ending back in Seoul before spending a few days in China on the way home to OZ.

Fiction, Recollections & News

A cockatoo named Einstein

 

 

 

A couple of days ago a story about sulphur-crested cockatoos went semi-viral, probably in an attempt to lift spirits during Sydney's new Covid-19 lock-down. It appears that some smart cocky worked out how to open wheelie-bin lids.  That's not a surprise - see below.  What is surprising is that others are copying him and the practice is spreading outwards so that it can be mapped in a growing circle of awareness. The cockies are also choosing the red (household rubbish) bins that may contain food, disregarding yellow (cans and bottles); blue (paper and cardboard) and green bins (garden clippings). Yet, now they have also been observed checking-out other potentially food containing bins.

One has even been observed re-closing the lid - presumably to prevent other birds getting to the food.

Back in the 1950's I was given a pet sulphur-crested cockatoo we named Einstein. I was in primary school and I didn't yet know who Einstein was. My father suggested the name - explaining that Einstein was 'a wise old bird'.

Opinions and Philosophy

The Hydrogen Economy

 

 

 

 

Since I first published an article on this subject I've been taken to task by a young family member for being too negative about the prospects of a Hydrogen Economy, mainly because I failed to mention 'clean green hydrogen' generated from surplus electricity, employing electrolysis.

Back in 1874 Jules Verne had a similar vision but failed to identify the source of the energy, 'doubtless electricity', required to disassociate the hydrogen and oxygen. 

Coal; oil and gas; peat; wood; bagasse; wind; waves; solar radiation; uranium; and so on; are sources of energy.  But electricity is not. 

Electricity (and hydrogen derived from it) is simply a means of transporting and utilising energy - see How does electricity work? on this website.
