Laos

 

 

The Lao People's Democratic Republic is a communist country, like China to the North and Vietnam with which it shares its Eastern border. 

And like the bordering communist countries, the government has embraced limited private ownership and free market capitalism, in theory.  But there remain powerful vested interests, and residual pockets of political power, particularly in the agricultural sector, and corruption is a significant issue. 

During the past decade tourism has become an important source of income and is now generating around a third of the Nation's domestic product.  Tourism is centred on Luang Prabang and to a lesser extent the Plane of Jars and the capital, Vientiane.

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.

In Defence of Secrecy

 

 

Julian Assange is in the news again. 

I have commented on his theories and his worries before.

I know no more than you do about his worries; except to say that in his shoes I would be worried too.  

But I take issue with his unqualified crusade to reveal the World’s secrets.  I disagree that secrets are always a bad thing.
