Travel

Southern England

 

 

 

In mid July 2016 Wendy and I took flight again to Europe.  Those who follow these travel diaries will note that part of out trip last year was cut when Wendy's mum took ill.  In particular we missed out on a planned trip to Romania and eastern Germany.  This time our British sojourn would be interrupted for a few days by a side-trip to Copenhagen and Roskilde in Denmark.

I'm seeing on TV senior politicians, including the Liberal PM and involved Labor Victorians (bi-partisan), gathering in Morwell in Victoria to announce that jobs in the Latrobe Valley have been saved by a Japanese consortium that will build a pilot plant to convert brown coal to hydrogen. Read Here...

I had to pinch myself to check that our screen had not somehow turned itself into Lewis Carroll's looking glass and sucked me through to the other side.

Fans of the Reverend Dodgson's (Lewis Carroll's) work will recall some 'weird shit' in Wonderland like: Alice growing and shrinking; a disembodied cat coming and going; and babies turning into pigs.  But these adventures are put into the shade by Alice's subsequent experiences: Through the Looking-Glass

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.
