The Pope condemned climate change prophets of doom but he says that to combat climate change nuclear power must be used?? And he warned them that any solutions to global warming must be based on firm evidence and not on dubious ideology. He is the leader of more than a billion Roman Catholics and he said that fears over man-made emissions melting the ice caps and causing a wave of unprecedented disasters were nothing more than scare-mongering. He thought that some concerns may be valid but that the international community must base its policies on science and not dogma of the environmentalist movement..
The 80-year-old Pope said the world needed to care for the environment but not to the point where the welfare of animals and plants was given a greater priority than that of mankind.
Does the Pope not know or understand that extinction of plants and animals is happening on a massive scale and largely as a result of human activities and increased over many years by the teachings in the bible go forth and populate the world and have dominion over plants and animals? Does he also not understand that it is the very plants and animals-the biosphere right down to the extremely important micro flora, fauna, viruses, bacteria, plankton etc supporting them, and constituting the largest amount of life on this planet, singularly strengthening a synergism are actually more important than all humans and without them we would all be dead no matter what ideology or faith we have. We come last in the scheme of things! We have to look after them totally! And that means looking after the environment totally! The total environment is the currency of our priority. Without it we have none. And to rely on nuclear power as the only future major power source saving the planet shows little or no understanding of the immense power of natural energy sources. It also shows little regard for the fact that the nuclear industry can never be a safe one because of the world’s entrenchment in crazy and dubious ideologies and we are in dire need to branch out on a safe power source devoid of either nuclear or fossil fuel with science as the currency. It is of great concern that a man is such a position leading the world of so many people will by his very pronouncements increase the chances of an apocalypse.

There’s no getting away with the fact that natural flows of renewable energies are able to proved all the world's power. And another example; tide and wave power. The CETO project in western Australia and wave technology demonstration at Port Kembla show that in just wave alone, wave power can provide all Australia’s power ten times over! There is only one sensible way to tackle the climate crisis-not by fossil fuel or nuclear but by renewable technologies that will provide the new economy and wealth for all Australians.

What a great day to see John Howard and the Liberal Party out of office and John Howard loosing his seat!!!
Now at last there is great hope we should see renewable energy going down the path it should have gone at least 30 years ago, being seriously taken as THE major alternative to coal and nuclear power with gas being only a backup-if at all. We all know a liberal government would have secured the nuclear industry and renewables would have only become a niche market at best. We need to put the case to the politicians that renewable energy is the way to go and leave the coal in the ground-and also the uranium. Right now of course they (Labor Party) have no perception of this and the liberals don't even want to know. The first thing to do is to show that renewable energy can provide all power simply because as any renewable energy scientist knows, there is enough free energy there to provide ALL the world with power indefinitely and we are getting better at extracting it and transmitting it to the people. And we need to continue doing this full bore because it's the safest strategically and environmentally, and is economically the best way.
In taking this road all renewable options should be put on the table as opponents will always argue that there is not enough capacity to provide reliable base power 24/7 e.g. wind or solar photo voltaic, solar thermal or even wave power and therefore requiring coal or nuclear to provide base power and that all the eggs should not be put into one basket-just so long as coal and nuclear have the most eggs and baskets! The argument usually centres on one renewable source completely forgetting that renewable energy is wide spread and is available from many sources and combined is continuous. And the public needs to know that in Australia alone there are many companies involved in renewable energy, perhaps several score, and many have their parent companies overseas but that we in Australia should be home to them and our scientists should be brought back.

This planet is saying to us we have to produce base power without carbon and do it now!!! There is a way. Use natural flows. We have the know-how and technology to provide all our energy needs using solar and wind with integrated storage of the energy. In the case of solar using photo voltaic cells, storage can done by using flow batteries, and in the case of solar thermal it can be done thermo chemically, and in the case of wind also flow battery storage can be used. Base power for industry can be achieved 24/7 this way. Wind and photo voltaic cells also have the advantage of distribution so distribution of these adds to the capacity factor and or can allow for less storage requirement. In some countries geothermal energy can provide large amounts of power 24/7 and tidal and wave flows are possible in many countries. Combinations of all of these could provide for an extremely reliable power supply. Doing anything else e.g. building nuclear power stations or developing “clean coal” or CO2 geosequestration is wasting time and will in the long run result in more CO2 in the atmosphere and in the case of nuclear, is only continuing what should be wound down as a dangerous technology, not only because of it’s inherent safety requirements but because the world will never have a safe nuclear industry because the world is entrenched in crazy ideologies. And it can’t provide power without carbon because of the progression of the fuel from mining through to refining transport and disposal. The biggest uranium mine in the world Olympic Dam will be expanded to become the deepest and largest hole in the world emitting carbon on a grand scale! And carbon will be produced in construction and decommissioning. There is only one way to go to satisfy zero carbon now; it’s by using natural flows of renewable energy. For any success for renewable energy in the commercial world to happen it has to provide base power for industry 24/7. Storage of the sun’s energy together with competitive prices to the consumer is the key to this. We are at the crossroads of this happening now with employment of cheap construction materials, zero input energy cost and the utilization of already mature technologies and large-scale setups enabling solar power to enter the commercialization stage. See http://www.ausra.com/ and http://www.trec-uk.org.uk/index.htm but no nuclear or fossil fuel power will be able to provide cheap clean and safe power in time to address the impending crisis in global warming caused by the human species. Only renewable energy from natural flows will do that. Lets get on with it!!

More than ever before we need a safe power source to power this world. The latest report by the CSIRO and The Bureau of Meteorology in Australia that we have come to the threshold where global warming is going to go out of control demonstrates clearly that we must move immediately from CO2 polluting power production to non-CO2 power production. The only way to do this is to shut down all the fossil fuel burning industries. That’s a mad thing to do you say. I don’t think so given the fact that within the life of our present generation this may easily happen from disastrous weather changes. No food production will shut down anything!! It probably will not be quite that bad but pretty close to it. And now we have the Vatican, James Lovelock, Hans Blix and Green Peace and many other environmentalists advocating nuclear power to help prevent global warming. They don’t cite however nuclear proliferation and the fact that we will never have a safe nuclear industry because the world is entrenched in crazy ideologies or the huge amounts of CO2 to mine uranium, transport and refine it (Olympic Dam the largest hole in the world and uranium mine will produce millions of tons of CO2) or the CO2 produced in building nuclear power stations and their decommissioning. John Howard our prime minister has announced that elections will be held on November 24th. and nuclear power will not be on the agenda. But the Howard government will if it’s returned with the nuclear issue now tucked presently away bring that up to full bore. Basically the Australian Greens Party has the only published political policy to deal with the CO2 threat. The Labor Party has not said what it will do but has intimated that they have a number of renewable energy strategies. There is only one way to go. Don’t vote for the Howard Government!

To all those who think that solar thermal power or in fact any renewable power employing natural flows will still have limited 24/7 base power output- there are a number of storage options already in existence. A star performer in these is the disassociation of ammonia closed loop system. This enables power to be produced 24/7 even in the wintertime from a summer sun without any power loss from storage at ambient temperatures! Correct scaling with input, load and time enables this as with any storage system. And there is an explosion of promising technologies being developed. It’s worth keeping in mind that the mount of the sun’s energy falling on Australia in one day is equal to all the world’s requirements for 6 months 24/7. And wind, tidal and wave are equally of large scale and can be stored actually surprisingly cheaply. An explanation of the ammonia storage system is at, http://engnet.anu.edu.au/DEresearch/solarthermal/high_temp/thermochem/index.php

How can we have an informed debate and vote on the issue when a great deal of information is deliberately hidden? The public knows that there is nuclear power, fossil fuel power, and then there are the renewables. But the thrust about renewables is that they can’t provide base power for industry 24/7. This is entirely incorrect.Nuclear power stations will not be a reliable power source in a warming global climate Dave Lochbaum of the Union of Concerned Scientists' nuclear safety project director said. "The industry can't use global warming as a justification for building more plants without papering over the fact that they don't do well in extremely hot weather.” We also have to cite the very obvious that we will never have a safe nuclear industry because we live in a world entrenched in crazy ideologies. We are in dire need to have safe cheap power sources and reduce global warming as well and only renewables will in the end do that. We should understand and be aware that renewable power sources can be the alternative to nuclear power despite what the pro nuclear lobby says. We are at the crossroads of that happening now.

There has been a breakthrough in renewable energy base power production! I refer to solar thermal power using a cheap flat mirror system and storage by the disassociation of ammonia in an endothermic reactor then stored at ambient temperature and used at any later time even during wintertime the sun's energy is not lost being chemically locked up. Then reapplied to an exothermic reactor heat is produced at about 500 degrees to provide steam for power generation. This closed loop system enables 24/7 base power production for industry and it also is able to provide medium or peak power on demand. Not only that the storage system is easy to do and cheap and is based on mature technology and enables the sun’s energy to be stored any length of time without loss so that the energy can be extracted in the wintertime if necessary or any time in the future! No other storage system can do this and it is a real breakthrough. A gigawatt plant is right now being built in America financed by venture capitalist Vinod Khosla who says that solar thermal power is poised for explosive growth because of it’s low costs together with Australian scientist Dr David Mills who had to leave Australia because of our government’s unfavorable policies. We could have had this happening in Australia if our government had been receptive. There is certainly no need to have nuclear power here! And in Europe a TRANS-CSP report commissioned by the German government calculates that solar thermal power is likely to become one of the cheapest sources of power including the cost of transmission. Not producing any carbon and it does not have safety issues it’s easy to see why. This is the power that needs to be, and can be sent to third world counties and the rest of Europe via High Voltage Direct Current Transmission lines from solar thermal plants in North African deserts or the Middle East with only 3% loss in transmission. In fact the whole world could use this as a major power source as there are many deserts around. The potential for it to power the world cleanly and safely and reduce greenhouse gasses at the same time is a real bonus. And it is being done now. Lets get on with it and continue! A general understanding and awareness of solar thermal power (CSP) can be seen on http://www.trec-uk.org.uk/index.htm and http://www.trec.net.au/ and understanding of the storage system in schematic form can be seen at http://engnet.anu.edu.au/DEresearch/solarthermal/high_temp/thermochem/index.php

Far from being inefficient, and a negative for the economy solar thermal power (CSP) has huge potential to supply the world with a major way to produce clean electricity, jobs and wealth. It has been calculated that, if it was covered with CSP plants, an area of hot desert measuring 254 km x 254 km—which is less than 1% of the area of deserts around the world—would generate as much electricity as the world currently consumes. If used in Australia alone and area 50KM square in desert areas would supply all of Australia’s energy requirements. And it is feasible and economic to transmit solar electricity over long distances using highly-efficient 'HVDC' transmission lines. 90% of the world's population could be supplied from this source.
US venture capitalist Vinod Khosla of Sun Microsystems says that CSP is poised for explosive growth because of its low costs. In part this has been brought about by the use of simple cheap flat mirrors and the ammonia storage method developed by Australian scientist Dr David Mills. The 'TRANS-CSP' report, commissioned by the German government, calculates that CSP is likely to become one of the cheapest sources of electricity in Europe, including the cost of transmission. Information about CSP can be found at www.trec-uk.org.uk and www.trec.net.au
