The question is not whether we need any particular power generation technology or not. The question is whether allowing nuclear can lower the cost of reducing emissions, and whether the downsides outweigh that lower cost.

I refer to ‘concentrating solar power’ (CSP), the technique of concentrating sunlight using mirrors to create heat, and then using the heat to raise steam and drive turbines and generators, just like a conventional power station. It is possible to store solar heat in melted salt or other substance so that electricity generation may continue through the night or on cloudy days. This technology has been generating electricity successfully in California since 1985 and half a million Californians currently get their electricity from this source. CSP plants are now being planned or built in many parts of the world.

CSP works best in hot deserts and, of course, these are not always nearby! But with transmission losses at only about 3% per 1000 km, it is entirely feasible and economic to transmit solar electricity throughout Australia from the Australian desert using highly-efficient ‘HVDC’ transmission lines. A small portion of the Australian desert would be sufficient to meet all of the country’s needs for electricity.

Waste heat from electricity generation in a CSP plant can be used to create fresh water by desalination of sea water: a very useful by-product in arid regions.

In the ‘TRANS-CSP’ report commissioned by the German government, it is estimated that CSP electricity, imported from North Africa and the Middle East, could become one of the cheapest sources of electricity in Europe, including the cost of transmission. A large-scale HVDC transmission grid has also been proposed by Airtricity as a means of optimising the use of wind power throughout Europe.

Well perhaps we do. If we all clown around and don’t look at the big picture we deserve a Nuke Power Plant right in our front yards(not the backyards like the alternatives) and that is what we will get because the best place to build them is near the city and by the sea or river. Sounds like the most expensive real estate in Australia to me, and how long will it be there? Well for ever because you can never live where a decommissioned Nuke Power Stations was which is sad considering that Nuclear Fuel will only last two hundred years.

Well that is just a by the way thing the real problem with Nuclear Power Stations is this.
Have you ever noticed what the first target of war is? Ask Israel when they bombed Lebanon or America when they bomber Iraq and Yugoslavia. Ask the Germans or British in WW1 and WW2. They will tell you it is the power stations.

If you cripple power stations with conventional bombs you shut down most of the industries immediately, hence target number one.

Now if there have always been wars, well there may always be wars and if the first target is power stations For God Sake don’t build a nuclear one. Why develop nuclear weapons when all you have to do is bomb a Nuclear Power Station with a conventional bomb to create a Chernobyl and if we have 12 well we could have 12 Chernobyl’s.

So you ask me, does anyone need nuclear power stations?
Is there a county on Earth that is immune to war or terrorism?
If you find one then we may consider the pros and cons.

I completely agree with you. My take is that Howard has not moved on climate change for 3 reasons:

1. As the Ace to wedge Labor when the time came. That time is now. And the “n” word is a good wedge for Labor. Though I think Howard over-estimated the political goals he could kick on this.

2. Coal is our biggest exporter, so challenging/threatening that has uncertain and potentially explosive political implications. Best to keep away as long as it is feasibly possible. Never forget that Howard is reactionary.

3. No political upside in joining the EU’s cynical economic jihad against the US.

Australia has naturally high and potentially life-threatening radioactivity in various places, for example Paralana Springs in South Australia http://www.science.uts.edu.au/news/2004/paralana.html

If the radioactive contamination at Paralana Springs was man-made, hairy-headed hippies and old-maids would march in their thousands if the Government failed to clean up the mess, yet Paralana Springs is a tourist attraction. Go figure!

Australia shouldn’t have nuclear power for economic reasons rather than environmental and health reasons.

I don’t believe the Liberals are sincere in their nuclear interest. Considering the statements being made by the Howard government in light of only a few governmental reports – it’s difficult to interpret it as anything other than a political wedge. At the same time, when viewed from a demonstrated technical capabilities perspective, Labour’s claims to implement massive emissions reductions appear similarly impossible without nuclear.

Furthermore, who are we to point to emissions from China and India using country to country comparisons with Australia? This makes absolutely no sense. Why should their combined 2.2 billion or so people not be entitled to the same prosperity, the same consumption, the same emissions as Australia, the USA or Europe on a per-capita basis? Do we really believe a ‘do as I say, not as I do’ approach is going to be taken seriously? Is this international leadership at its best? I certainly hope not. In fact I believe Australia can do better.

But if my take is correct and hypocrisy wins over logic, hard decisions and tangible action, we’ll have no nuclear and no significant per-capita emissions reductions; which brings me to the irony – Australia seems to be first in the queue of developed countries headed for some serious blows from climate change – many of which are believed to be in progress already.

With Rio Tinto discovering Kryptonite http://en.wikipedia.org/wiki/Jadarite it’s all starting to make sense….(But is K-Rudd – Clark Kent?)

Philosophically, the idea of having distributed power generation like solar panels on everyone’s roof feeding back into the grid, is a total anathema to someone like John Howard.

Much more preferable to have Montgomery Burns or Energy Australia controlling the power generation network – & how exactly can you gouge profits when all your customers are also your suppliers… I suspect alot of customers will also just leave the grid completely when self sufficient, all in all, not a business model most moguls would want to take home to mother.

The alternative for this waste is?

Seriously, what else are we to do with it? Wish it away?

As for the capitalist system of supply and demand, it’s been around a very very long time and I suspect it’s got a lot of life left in it.
