Here we are in Seattle. And what else does one do in Seattle? Why, visit the iconic Space Needle and go out to the Boeing plant and the Museum of Flight.

The Space Needle, built for the 'Seattle World Fair' in 1962, was briefly the tallest structure west of the Mississippi.  Now, its height is unremarkable, it's shorter, even, than Sydney's Centrepoint Tower.

Initially we couldnt see it, it was hidden behind the city's many office towers.  But it does have a thrilling glass floor that rotates like the restaurant at Centrepoint in Sydney. Indeed, this floor was once opaque, it was a restaurant too. 

Of course, once you are above a hundred or so metres acrophobia kicks-in, so the adrenaline thrill, for those not yet accustomed to the appearance of nothing beneath their feet, is just as potent, as the squeals, from some, and white faces, on others, attest. In this respect, this glass floor is just as scary, as the glass floor areas at the Tokyo Tower, not to mention the very much higher outward leaning walls at the Willis Tower, in Chicago.

'The Space Needle' was constructed at the height of the 'space-race', that began a decade earlier. Its unique shape came to symbolise the era, referenced in the 'Jetsons' TV show.

The 'space-race' had began with the Russian 'Sputnik' satellite in 1952; followed by Laika in 1957, the first dog in space, on Sputnik 2. The USSR then leapt ahead in 1961 when Yuri Gagarin, became the first Cosmonaut.

The American program, initially based on the German V-2 rocket, and directed by ex-Nazi, Wernher Von Braun, had faltered from one disaster to another, until 1962 when newly elected President Kennedy, who had been critical of the program in opposition, declared that the goal was now to: "walk on the Moon by the end of the decade".  America just made it in time, with that "one small step for (a) man...", in July 1969.

Of course, the real concern was mutually assured destruction. Space supremacy was essential in the event of nuclear war. How else could we wipe out those Ruskies, before they got us?

 

"Once the rockets are up, who cares where they come down..."

 

So, the competition with Russia continued. And now others had joined the race. For example, Australia that had shared a military rocket and atomic bomb program with the UK, launched its own satellite in 1967, using reassembled rocket components from the US and UK.

Yet, as we saw in Houston on our last trip to America, that early competition finally came to an end with cooperation; to build and staff the International Space Station.

On a similar theme, a little out of town, to the south, we could tell it by the mountain, is the Museum of Flight.  This houses an amazing collection of historic aircraft from many countries, both allied and combatant, as many are military.  There are also many commercial aircraft, mainly from the Boeing stable, including an old Air Force One. They also have a supersonic Aérospatiale/BAC Concorde that, like many of the aircraft here, is open for inspection.  Very interesting.

Of special interest was the collection of pilotless aircraft, beginning with the German V1 'buzzbomb'
with other examples, through to the present generation of US drones.
These have remote pilots.  But now onboard AI is making them semi of fully autonomous.
It's easy to predict that most military aircraft will soon be pilotless, because a huge proportion of their cost;
and major limit on their manoeuvrability; is just to keep their encapsulated human alive. 

 

To get to Vancouver we caught the bus.  The international bus terminal is conveniently connected with the metro, in turn to our hotel, where it was most useful and convenient.

Southern France

Touring in the South of France

September 2014

 

Lyon

Off the plane we are welcomed by a warm Autumn day in the south of France.  Fragrant and green.

Lyon is the first step on our short stay in Southern France, touring in leisurely hops by car, down the Rhône valley from Lyon to Avignon and then to Aix and Nice with various stops along the way.

Months earlier I’d booked a car from Lyon Airport to be dropped off at Nice Airport.  I’d tried booking town centre to town centre but there was nothing available.

This meant I got to drive an unfamiliar car, with no gearstick or ignition switch and various other novel idiosyncrasies, ‘straight off the plane’.  But I managed to work it out and we got to see the countryside between the airport and the city and quite a bit of the outer suburbs at our own pace.  Fortunately we had ‘Madam Butterfly’ with us (more of her later) else we could never have reached our hotel through the maze of one way streets.

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.

Carbon Capture and Storage (original)

(Carbon Sequestration)

At the present state of technological development in NSW we have few (perhaps no) alternatives to burning coal.  But there is a fundamental issue with the proposed underground sequestration of carbon dioxide (CO2) as a means of reducing the impact of coal burning on the atmosphere. This is the same issue that plagues the whole current energy debate.  It is the issue of scale. 

Disposal of liquid CO2: underground; below the seabed; in depleted oil or gas reservoirs; or in deep saline aquifers is technically possible and is already practiced in some oil fields to improve oil extraction.  But the scale required for meaningful sequestration of coal sourced carbon dioxide is an enormous engineering and environmental challenge of quite a different magnitude. 

It is one thing to land a man on the Moon; it is another to relocate the Great Pyramid (of Cheops) there.
