    It's not just Chernobyl, it's the waste it produces, and the fact that once again we abdicate our responsibilities as individuals to some centralized producer when we should be moving toward self sufficiency, and reducing the toxic load on the planet.

    Yeh cool. And that's how our iron ore was formed.

    The waste it produces is minuscule compared to the power it generates, plus the more waste is produced, the more people are going to try and recycle it, reducing wastage even more.

    are humans involved? thats the bit about 'impossible' i dont buy.

    Im totally cool with the waste as well. africa is huge, they need money - we could pretty easily bury it there.

    I'm not sure there is an awful lot you can do with nuclear waste that is going to change my mind on that one. We will have to agree to disagree.

    A good solution, but I thought it was the waste product people were more concerned with?

    As a short term solution, I guess it could be OK, but there's nothing really sustainable about Nuclear power. Eventually we'll be looking at a series of new problems associated with the waste product and its disposal. Not to mention, a nuclear reactor is pretty much 1 of the most energy intensive structures to build. Takes HUGE amount of embodied energy just to get it up and running (I've been lead to believe).

    Waste products of all shapes and sizes can be recycles, reprocessed and reused. Plus the majority of people simply dont understand radiation and how it works.

    I dont really know much about how much energy it takes to build a nuclear reactor. I can tell you that the controllers required to regulate intermittent power sources like wind and to a lesser extent solar are a complete bitch and a half, are fucking expensive, and like all this, more research into them = a better product. Just like research into reprocessing nuclear waste.

    Basically im saying that we dont have nuclear power because people are ignorant. Change that, and you will be fine,

    Can you at least point out your problems with it rather than just burying your head in the sand?

    Ok, saw your next post. Gimmie a few minutes.

    2. How It Doesn’t Work – Risks and Dangers of Nuclear Energy

    Proliferation Risks
    Dont really have that much to say here, other than trying to stop humans from killing each other is about as useful as wishing the sun to turn itself off. The technical knowledge required prohibits individuals from making a bomb. International pressure and MAD means no country will actually set one off against another country

    Risk of Accident
    blahblahblah Chernobyl power plant blah blah blah

    Simply cant happen with modern western reactor design. The amount of radiation released by 3 mile island was less than the amount of radiation you receive when you eat a banana. Much much less. http://en.wikipedia.org/wiki/Banana_equivalent_dose

    Environmental Degradation
    This bit I dont really have an argument for. Land gets fucked up with you mine things. No disputing that. Just one question though. The metal you are using for the solar panels and wind turbines. Where are you gonna get that from?
    Nuclear Waste
    this is just bullllllshit. Also see my point on people not knowing how radiation works.

    Reprocessing can reduce waste. The more we reprocess the better we get at it. The better we get at it, the more waste turns out not to be waste.

    Well there can't be harm in reducing risk. What's the worst thing a solar panel can do to you? Sure as hell couldn't be used to blow up your neighbourhood.

    Also, I'm perfectly capable of understanding any information regarding 'how it really works' you may care to send my way. Please go ahead and explain it to me.

    Edit: read the info in the link. I still don't get why you would be OK with a smaller amount of deadly waste when you have technology that has no potential to be used in nuclear weapons. That will never make sense to me. All it takes is one religious nutcase with enough money, fervour and charisma to gather a crew of similarly deranged individuals, and bad, bad things can happen to many people. I have children, I'm a pacifist, and a vegetarian for 15 years. I just can't support something that has the potential to harm other living creatures no matter how remote. It only takes 8kg of waste to produce a bomb of similar capabilities as the one that hit Nagasaki.

    Like I said. We can just agree to disagree.

    I know a guy who knows a guy whos brothers mothers sisters dogs breeder once saw this dude being crushed by a solar panel. THEREFORE ALL SOLAR PANELS ARE KILLERS. Plus, when was the last time you saw a nuclear power plant lurking on top of someones house, waiting? Huh? yeah, thats right never.

    Solar is also inadequate to provide our power needs. Intermittent power sources are always going to be problematic until we improve battery technology*

    The great thing about nuclear power is that its stable and always on and constant and that is what you need to provide the base load power needs. Then use renewable like solar and wind and hydro to generate the peak load. Its a happy medium that covers the majority of situations without creating immense amounts of pollution. Its our best shot as a race. Please feel free to prove me wrong.

    If you want to learn more, I suggest wikipedia. http://en.wikipedia.org/wiki/Radioactive_waste Helped me out.


    *progress is being made in this area. I know of some places that use solar power to pump water to the top of a hill during the day, and then release the water and use it to create electricity during the night. Chemical batteries are still shithouse though.

    A different side of the nuclear issue - has anyone seen Blowing in the Wind?

    It's a doco about the tonnes of radioactive dust in the outback, left over from war-games with the US Army, which uses depleted uranium munitions; which makes for highly effective projectile weaponry & is a deviously sly and virtually cost-free way of disposing of nuclear waste.. just as evil (if not more so) as antipersonnel mines & cluster bombs yet it rarely gets any mainstream media coverage..

    What I want to know is why the fuck our gubbermint would allow their use... Then again we have a history of allowing friendly powers to irradiate the outback

    I'm not entering this renewable versus Nuclear debate, however I just wanna echo your sentiment here. Batteries are fucking expensive and really not that great at the moment, short life and massive capital costs (which aren't any cheaper when you need to replace your entire battery bank) mean batteries should only be used to augment base power and help to better control base power generation (by gensets or whatevs).

    while i'm not anti-nuclear i think it's a dead horse. isn't it estimated it'll take about 10 years to design, legislate, regulate, develop, build, test and monitor a nuclear power plant in australia? if so i don't see us getting one. plus who are we going to get to build it? all our nuclear experts are now overseas. not to mention the endless legal and political implications. nah, best to bet on renewable i think.

    This, x10.

    It's a waste of effort, pure and simple, compared to renewables.

    Nuclear has only ever been used with MASSIVE guvmint subsidies. The infrastructure has never, and is nowhere near, been existing for it to be an independently viable industry.

    You would need to spend at least as much, if not more, to get nuclear as a viable option as you would for a diversified renewables portfolio - and that wouldn't have any of the security/waste issues.

    Just a hint - take a look at what sitting on top of the world's dominant energy source has done for the Middle East. Want that kind of geopolitical interest down here?

    I hear fusion technology is the future but there hasn't quite been any massive breakthroughs in regards to the technology which allows constant reactions to generate high enough power output to make it economically viable.

    I did a little bit of reading on it a little while ago cause there was some article in the newspaper about a guy who designed his own reactor in America.

    Fucking awesome.

    To have something like this in W.A. would be amazing.

    10 times more powerful than anything on earth. In terms of the current ability to look into space (and back in time), we are sitting at 1 on a scale of 1 to 10. 10 would give us the ability to see the big bang, or light emitted from that point in time.

    The project is fucking huge, the data that would run through the system PER DAY is equivalent to the WHOLE of the internet data transmitted on EARTH (at current levels). The data going through the telescope, just the telescope, in 2020 when it could be operational will be equivalent to the internet traffic of the entire planet in 2020.

    The computer system used to run the project will be the world's largest computer system. Given that things like wifi were created as a by-product of astronomy, the project is quite exciting.

    I read somewhere it will cost around one to one and a half billion dollars, with maintenance after completion of about 100 million dollars a year. Pretty good value for money given the potential for discovery. The giant telescope may be a step up from the giant prawn and giant banana for tourism.

    considering the last thing we want is wallies with mobile phones wandering around the SKA, not in that way no.

    there's geraldton trying to make a case for becoming a research/tourist hub but time will tell.

    you may not know but one fot he problens with wind turbines is breakdowns due to the forces on the bearings and the fact they struggle with lubrication - essentially there is no lubrication good enough (whale oil probably is but hey thats a whole other kettle of fish) - the fat this spins on a horizontall axis will hopefully eliminate some of these problems.

    however

    the biggest argument against solar and wind and other alternative supplies of energy aside from cost is is baseload generation - ie you need x amount of power minimum to power city y

    if you cannot guarantee a baseload 24/7 for whatever the requirements of the time of day then you have to duplicate the alternative energy source with a conventional one.

    so the next thing they need to work on is storing power so we can build a bigger power source then store the excess for a rainy day so as to speak.

    The area which can support life in other solar systems is apparantely called the 'goldielocks zone'. That is, it's not too hot or too cold, the temperature is just right. Made me chortle a bit.

    read the next paragraph:

    Sadly, while the results of this study are hugely important, there are a couple of caveats to make: firstly, the mice in question were genetically modified to suffer from a lack of telomerase, which might have inflated the results of the tests relative to regular mice, but more importantly, an increase in telomerase in humans is "a hallmark of most human cancers."
    "a phrase, something deep and of consequence, that defines me as a person."

    NASA has discovered a new life form—called GFAJ-1—that doesn't share the biological building blocks of anything currently living in planet Earth. It's capable of using arsenic to build its DNA, RNA, proteins, and cell membranes. This changes everything.
