  1. There have been dam failures in Australia, but the one I am thinking of was an irrigation dam. Another in Qld is drained well down, due to fears about its stability.
  2. Not wishy washy. They are not really a problem anywhere as they never achieve anything, but the LNP are more dangerous. They are professional politicians and therefore only have one aim. To win the next election and don't let what is best for Australia get in the way.

    Phil. That story is older than the internet. Used to be called "Why Murphys' not at work today"
  4. One of the big users of power is air conditioning. I remember in the days when I was building reinforced concrete chimneys that even on the hottest of days we would be fairly cool, due to the chimney beneath us heating up and drawing air in at the base, which could get to quite a strong force as the chimney got higher. The theory could be used to cool buildings, just have a black painted chimney above the building to draw air in.
  5. We have heard a lot about the science and so far what has been predicted has occurred in some cases. Science is all about proof of your predictions. What I want to know is what is predicted with any real chance of happening. So far we have had dire warnings of every sort of catastrophy but they have not come true. One early prediction was that we would get more cyclones. That has actually been completely the reverse of what is happening. We also had more powerful cyclones predicted, again it has not happened. Coral degradation was supposed to kill all the reef and we have seen reports of half the reef dieing, which turned out to be part of the Northern third of the reef. I am ready to believe that mankind has some effect on climate, but I am not ready to accept all the tales of woe that "climate scientists" and do gooders come up with.
  6. I don't think you can say the uptake of rooftop solar was caused by people wanting to reduce climate change. It was to reduce the cost of electricity to themselves. It has worked for most of us, even though the supply companies may have increased fees. the fact that we can sell what we don't use ourselves lessens the cost. What we need is a good way to store the electricity we produce, then we could go off grid. The mad thing was that government set the price we can sell to the supply company at more than our cost to buy. I am a firm believer that it would be better to be off grid as it would cut down the costs of transmission. in the same way I have been producing most of my water needs in the last 50 years, by using rainwater, rather than town water. Not such a good idea as I have to pay the council about $500 a year for the privelige of having piped water to my property, that is before I use any at nearly $2 per Kl
  7. I think we would have difficulty keeping up with the evaporation rate. We would never fill Lake Eyre, but we would get a big pile of salt. Now all we need is a means to get the salt to absorb moisture and then extract the moisture from the salt and use it for irrigation.
  8. I once designed a zig zag driveway into a commercial building to reduce the gradient, have to watch out for bottoming the chassis where driveway meets garage floor.
  9. We had a scheme to build a big dam which would be used for irrigation and also would lead to populating the area. The dam was built and a lot of rice planted. Result was an explosion in the numbers of ducks, which overwhelmed the rice growers. Resulting in very little agricultural build up for years, but there has been a big mango growth I believe lately and also vegetables. Sugar was tried but the growers on the east coast were against it. They said it would result in disease from Indonesia getting in to Australia and they were correct, so that idea died. There has even even been talk of pumping that water to an area further South for agricultural use. They assume ducks can' t fly? Anyway The Ord River scheme looked good in theory, but it didn't work. Bradfield wanted to fill Lake Eyre with water from the ocean, using explosives left over from WW2 to dig a channel there. If he had gone ahead I reckon we would have had enough salt to provide the world with all it needs and more.
  10. A few years ago I saw a steam car at a field day in Sheffield in Tassie. Rather like a big pram on 4 wheels with a silent engine. Very quick to get going it was oil powered. Useful as a town car I would suspect.
  11. I just had the following sent to me. It seems to be a sane and well considered summation of the bushfire problem. Obviously a loss adjuster would know what he is talking about and also be advising the insurance companies. The PM is putting forward the idea of a Royal Commission into the fires. Going on past performance of recent royal commissions I cannot see any good coming out of it. We had a Royal commission into the banking sector and that has done nothing. There are still the same old faces at the board meetings an the government has even suggested gong against one of the recommendations in an effort to make housing more affordable. I am writing this because I am appalled at the amount of near hysterical reaction to the recent NSW and Qld. bush-fires. My reasoning is not so much about the fires or the people effected, but about whether “man made” climate change is the underlying cause. Before I go further, my stance is not so much a personal but rather a professional reaction. I begin by telling those of you who don’t know, for a period of some 40 years, my work as a loss adjuster was involved with natural disasters, ranging from Cyclone Tracey through to a lesser involvement in 2009. I was appointed as National Chief Loss Adjuster, an advisory role, to the Insurance Council of Australia on all natural disasters but particularly bush-fires. This role was interactive with all agencies and spanned more than 10 years. It was both proactive in planning stages and reactive after the event. I was heavily involved in the 1983 Victorian fires. I acknowledge the advice of The Bureau of Meteorology and the Climate Council, is a reality to the effect the projected changes to climate, was derived from modeling, which strongly suggested change would occur unless man made contribution was reduced. Somehow or other, sections of our communities, have taken control of the scientific argument about the future and have interpreted it to mean the change has already occurred. Not so. Records I have seen, actually show that the slight upward trend in temperatures on a global scale seem to be in direct line with the earth’s ever occurring ”natural” climatic change patterns. History shows numerous ice ages, when the planet cooled, to corresponding heating up periods, over billions of years. This has always occurred. It is the nature of our planet and cannot be influenced by what man can or cannot do. On the other hand, the impact of humans is a future projection, well founded on scientific modeling. The true position, despite all the comments about what the current fires mean in a climate change scenario, is nobody can tell if there is any connection. What I can tell you with absolute certainty is that these fires, as bad as they were, are no more intense, widespread, dangerous or unexpected in outcome, to many previous and historic events. There is no accurate method to measure such outcomes. However, it is possible to look at prevailing conditions and contributing factors to seek patterns or influential factors. Take a look at the following comparative data, much of which has been ignored by the frantic argument to directly link man made climate change to the outbreak and effects of these latest fires. I detail some of the arguments I have heard go unchallenged or are simply ignored and unreported, particularly by the ABC who are the appointed official national disaster communications service. This the first time such fires have been rated as catastrophic. True, but notbecause they were rated any worse than many previous fires. In 2009, following the bush-fire inquiry, the defined categories of fire were renamed. Catastrophic was introduced as the most severe warning. So this description was never intended to make people think they were the worst fires ever. I have heard many media reports entrench this mistake. The fires are occurring earlier because of climate extending the summer risk. Can only be applicable in the North. However, NSW has a long history ofNovember and December bush-fires. In 1944, the Blue Mountains lost 27 homes and other property in November. Since then, I can recall at least 3 other similarly timed events in NSW. So this year was not unique, as has been strongly inferred by many reporters. In southern areas, January and February have historically been prone to outbreaks. These fires are the most widespread and worst ever. They certainly weredisastrous. However, it is impossible to compare unless it can be based on raw data. Have more lives been lost than ever before. No, although 1 is far too many, in 2009, 173 people died. In 1983, 75 people died. In 1962, 62 people died. In that decade one of the victims in Eltham North was George Crowe, my Grandfather and Grandma’s father in law. In 1967, it was reported that 2,600 square kms of land was devastated in just 5 hours (Just try to imagine that ferocity). In 2009 there were 2030 homes destroyed and in 1983 there were 6,000 homes and other buildings destroyed. Does this define which fire was the worst. NO. All fires are bad but to try and claim the current fires are the worst ever is a blatant disregard for historical fact. Worse still, it is a deliberate attempt to scare people into accepting the fanatical side of the global warming argument, by accepting radical changes to our economy, power generation and mining {let alone agriculture and transport} must occur right now and in a premature manner. The so called re-definition of the predicted changes into an emergency, is a way to virtually destroy our entire way of life. The fires were started as a result of climate changed conditions. Clearly wrong. 80% of fires were started by people either deliberately or accidentally lighting them. Dry lightning strikes have been long recorded and are nothing new. What has our Media and ABC generally ignored. One of the most clear databased facts, reported out of the 2009 Inquiry, was the finding that fire intensity is proportional to and severely aggravated by fire loads created by undergrowth and forest floor debris accumulation. We can’t control wind and heat but we can control fuel load. Ask any active Rural or Country serving fireman what they think of this hazard. Then ask your Green Party representative, why they have influenced the management of National Park maintenance, as well as local government reserves, to leave far too much of the forest floor intact at any cost. Winter back burning, firewood removal and general debris clearance has been widely restricted by stupid laws. They argue it preserves natural ecosystems that rely on such decaying material. Well, systematic removal of this fuel load may well disrupt some Eco-systems, consider this;. A bush-fire positively destroys them all. The only identifiable and recently introduced risk factor, is the environmental law changes that have impacted a fire’s intensity potential and capacity to burn faster and hotter. Find this hard to believe? Go into a forest and try setting fire to a living gum tree with a match. Now stoop down and see if you get any better results from the dead and therefore dry undergrowth at your feet. This is the effect ember spread has on adjoining bush-land. There is much more to say about bringing sanity back into discussions and I have my own opinion that if you believe the science of global warming, stick to the science and ignore the fanatical self professed experts, like some of the current crop of Green Party politicians and shrieking media, self appointed, experts. No, before it can be said. I was not self appointed in my former career positions. I can only reflect that the handful of ex-firemen who were paraded before the media, may have had other agendas. The spokesman listed his current occupation as a “Climate Change Consultant”. Another said outright, on camera, that fires have always been linked to climate change. I prefer to listen to our Indigenous community who talk of bush-fire management over thousands of years. - oops before any hint of an industrial age, meat production or mining. Les Crowe.

  12. I had six months in the UK where we had lunches provided from hot boxes and they were appalling. The ridiculous thing is that they were cooked at our base camp, where we had really good breakfasts and dinners. Even the cooks did not know why the lunches were so bad. Base meals were the best I ever had in the army, unlike other camps where I even had burnt boiled eggs.
  13. Big business has the government by the balls, that is if they ever had balls. State governments collect the royalties from coal and iron ore. Federal government told the states that if they raised royalties the GST would be withheld from them. In other words feds told states not to raise royalties. The feds run the country with no thought about what is good for Australia, only how to get in again at the next election. Both parties have demonstrated their incompetence financially and that is the reason we are so poor at the climate change problem. The only way government can get the money it wants is to push for more coal and iron ore to be exported. Forget the media, we can all see what is happening without them. A good first move would be to do away with compulsory voting, then only those who think about the future would bother to have a say. No more donkey vote and maybe less donkeys in Canberra.
  14. Cricket I looking up, but I still hear people saying that Smith should be captain again. A position he had and showed he was unfit for. We are out of the tennis. Does anyone remember our 11 Grand slam winners, including 6 Wimbledon. I don't think the Williams sisters or any of the current crop can equal that.
  15. We used to process those minerals and produce things such as Iron and steel, boat building thrived and we exported steel. Now all we do is export the raw materials and buy back the product, which is of poorer quality than what we used to produce. We are in the position of exporting vast amounts of LNG and not having enough for our own use. How good is that.
