  1. For three days now Melbourne has been under attack from extreme right wing ratbag elements that have caused much damage and plenty of disgust among normal Aussies. The core of these riots while having some legitimacy, have been hijacked by various extreme elements that have like leaches, jumped on the bandwagon, in a belief of achieving some sort of result or victory. In fact, thankfully the opposite has happened. The legitimate core involved tradies and members of the CMFEU union and a mandatory vaccination order. On the first day after trashing their head office, many were found not to be union members, plus the fact that the leaders of the union, do support mandatory vaccination, as also now required in many other industries and sections of the community...health care, airline, public servents...why the hell this section should be excempt is beyond me, particularly considering that a great portion of new cases of covid 19 are in that industry and on building sites. This has led to the shutdown of the industry for 2 weeks along with the mandatory vaccinations necessary. The union also now has said they will review any membership based on whether a member has been vaccinated. Here are some photos of examples of the merging of the radical right ratbags and the copy cat Trumpism that has infected some in Australia.......The first photo shows the trashing of their union office headquarters... The next is an example of utter disrespect when they gathered on the steps of Melbourne's shrine of rememberence for all those killed in war... And on top of all this Australia's east coast has yesterday expeienced a 5.8 magnitude earthquake with the epi-centre about 100 kms nor/east of Melbourne business district. Thankfully no loss of life and some minimal building damage. Don't smirk at the 5.8 magnitude, we aint that used to earthquakes in Australia! Oh, and don't forget the conspiracy nuts......
  2. Yep, I saw that, but we also have volcanic dust and debris to consider, obviously at the mercy of wind direction, plus reports of likely new fissures opening up. Again, no news appears to be good news, so maybe they are totally unaffected. found this https://www.volcanodiscovery.com/la-palma/news/141936/La-Palma-volcano-update-Stunning-time-lapse-video-of-eruption-seen-from-astrophysical-observatory.html An impressive time-lapse video has been posted by the astrophysical observatory Instituto de Astrofísica de Canarias of the first day of the La Cumbre Vieja volcano's eruption. Lava jets surpassed up to a few 100 m height. So looks like they are relatively safe.
  3. The recent and ongoing eruption of a Volcano on the Island of La-Palma in the Canary Islands is causing a huge amount of damage and destruction. While so far thankfully no lives have yet been lost, I,m unable to find much news in relation to the famous telescopes on that Island. https://phys.org/news/2021-09-toxic-gas-rivers-molten-lava.html extract: "The rivers of lava, up to six meters (nearly 20 feet) high, rolled down hillsides, burning and crushing everything in their path, as they gradually closed in on the island's more densely populated coast. One was bearing down on Todoque, where more than 1,000 people live, and where emergency services were preparing evacuations. So far, the eruption has destroyed around 190 houses and forced the evacuation of 6,000 people" .:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: Perhaps no news is good news. What I have found....... map of lava flow path at https://inews.co.uk/news/world/la-palma-volcano-map-where-eruption-canary-islands-areas-evacuated-explained-1208334 map showing telescope's location.....https://www.google.com/search?rlz=1C1RXQR_en-GBAU952AU952&tbs=lf:1,lf_ui:1&tbm=lcl&sxsrf=AOaemvK9_BWnAvMWGBdMVMyLtHew8H7ySA:1632257339287&q=canary+islands+telescopes&rflfq=1&num=10&ved=2ahUKEwiPgo-3-JDzAhVKwTgGHcsgCR8QtgN6BAgEEAc#rlfi=hd:;si:;mv:[[29.763010408115065,-12.575974862169556],[26.173746067251713,-20.74976074237757],null,[27.983309681558566,-16.662867802273563],7] The Gran Telescopio Canarias is a 10.4 m reflecting telescope located at the Roque de los Muchachos Observatory on the island of La Palma, in the Canaries, Spain. It is the world's largest single-aperture optical telescope. Construction of the telescope took seven years and cost €130 million. and................. The Isaac Newton Group of Telescopes or ING consists of three optical telescopes: the William Herschel Telescope, the Isaac Newton Telescope, and the Jacobus Kapteyn Telescope, operated by a collaboration between the UK Science and Technology Facilities Council, the Dutch NWO and the Spanish IAC. Wikipedia https://www.britannica.com/topic/Gran-Telescopio-Canarias ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: Obviously these 'scopes are important for the scientific world, but for the life of me, I am unable to find any direct reference to them, with relation to the current crisis, not in any way diminishing the extraordinary damages to people's properties and land. They do appear rather close according to the first link...... Anyone have any more info?
  4. Yep, another bright spark said similar earlier on......😉 Those thoughts coupled with the following could sum it up.... At present we have an out of control mob that have literally taken over the streets of Melbourne. A small part of that mob are a few "genuine" tradies that are questioning the mandatory vaccination for covid edict. But surrounded by that small group are a larger mob of leaches, well known professional protestors and anti vaxxers that have seen an opportunity to push their extreme agenda. One so called tradie was confronted by a news reporter and asked what they were marching/rioting for....he started ranting and raving about what he read on the Internet, then continued with some nonsense about Trumpism. In a word, sickening.
  5. Yeah, agreed good point, although you maybe too young to remember one of the original TV Star Trek episodes....a silicon based life Another was the Enterprise was always shown orbiting sideways...
  6. I'm an old bastard also, just turned 77 in fact, and the generally high standard of docos I watch don't uneccesarily indulge in that. Let me mention a couple that I think you may like, I did anyway...."Love and Bananas: an Elephant story" quite a moving doco that had me close to tears. "Blackfish" Another about Orcas, and the third is "Chasing Ice" Incredible beauty and photography illustrating pretty convincingly the warming of the planet and the finally "Journey To the edge of the Universe"...the first three, while not space orientated, are all excellent viewing, 10/10. Never was quite into the Dr Who series, don't ask me why, but did like the X-Files, although the producers of that show have a lot to answer for, with the rise in conspiracy nonsense with the gullible ones, and UFO's and anal probing Aliens...good entertainment though! Stargate another that didn't really sit too well with me, again don't ask me why...I do have all the Star Trek original series, and the New generation with Captain Picard, but thought the entertainment value dropped off somewhat after the Janeway Voyager series.
  7. As I said previously in agreement, docos are certainly a level above sci/fi for obvious reasons. I just don't undertand why or how you let such little things like background music and "awestruck" narration get to you. By far my favourite narrator is Sir David Attenborough, and of course the late, great Carl Sagan, imo the greatest scientific educator of our time. Of course sci/fi movies will have some errors in science, and certainly some are worse then others, but isn't that why they are called sci/fi? My favourite sc/fi movies were "2001: A Space Odyssey" head and shoulders above anything else, for its predicitve powers, and reasonable scientific accuracy. Others like "Mission to Mars", The Day The Earth Stood Still" 1953 version, Forbidden Planet and Gravity, were others. Excluding Gravity, the other three were more in line with the likelyhood of extra terrestrial life. Babylon 5 and the Star wars series, and Lost in Space, while in part enjoyable, I see as more fantasy then in any predicitve possibility. And of course, as we have argued before, the inevitable boots on Mars, is of course just that...inevitable. Time being the only debatable aspect. I mentioned Carl Sagan earlier and as most of us will know, his series "Cosmos" has been redone and narrated by Neil Degrasse Tyson. Both series should be compulsive viewing for all children. The Martian, yes another I failed to mention that was excellent, and of course the excellent portrayal of facts in Apollo XIII. Havn't seen Galaxy Quest.
  8. It's not beecee's dream at all. It is simply a news item regarding research into green hydrogen power sources, as complimentary with other sources. The goal of course being a reduction in global warming. The environment? All of us?
  9. No argument with that but Hydrogen does support efforts to limit global warming. Hence the need for governemnt backing in research into green Hydrogen, among the other aspects of clean power. Obviously producing Hydrogen via electrolysis is as "green" as we can get, and in conjunction with electricity from wind or solar, but to arrive at that target, further research and infrastructure is needed into industry size electrolysis mechanisms
  10. The overall point from where I am sitting, is that as many alternative sources of clean power needs to be researched. As research continues and methodologies are refined, they will become safer. On face value I would have thought that the biggest disadvantage of hydrogen power was in the storage capabilities. But even that can be reduced... https://www.whichcar.com.au/news/australian-breakthrough-brings-hydrogen-vehicles-closer extract: "Liquid hydrogen must be contained at incredibly high pressure or maintained at very low temperatures by complex cryogenic systems. But the CSIRO has developed a process that allows the gas to be converted into more stable liquid ammonia for transportation and then reconverted back to hydrogen once it has reached its destination or point of use. The CSIRO is keeping exact details of the membrane process a closely guarded secret, but says it is simple enough to complete using a modular unit that could travel with the liquid ammonia, or by equipment built into refuelling stations". :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: The crux of the matter is that our government, all governments should be backing continued research into green hydrogen power, along with solar and wind where possible. I don't believe we have a choice.
  11. Wooosh! At first that literaly went over my head! 😁
  12. Damn!!! I forgot the funny face!! here 😉🙂
  13. Supplementary article..... https://phys.org/news/2021-09-ingredient-cheaper-hydrogen-fuel-production.html SEPTEMBER 8, 2021 Mining waste could be used as an ingredient for cheaper hydrogen fuel production: Researchers have discovered a way to use mining waste as part of a potential cheaper catalyst for hydrogen fuel production. Water splitting reactions that produce hydrogen are triggered using rare platinum ($1450/ounce), iridium ($1370/ounce) and ruthenium ($367/ounce), or cheaper but less active metals—cobalt ($70,000/ton), nickel ($26,000/ton) and iron ($641/ton). Professor Ziqi Sun from the QUT School of Chemistry and Physics and QUT Centre for Materials Science and Dr. Hong Peng from the School of Chemical Engineering at the University of Queensland led research to create a new catalyst using only a small amount of these reactive metals. They combined them with feldspars, aluminosilicate rock minerals found in mining waste that Professor Sun said some companies pay about $30/ton to dispose of. In the experiment, featured on the August cover of Advanced Energy & Sustainability Research, the researchers triggered a water splitting reaction using heated-activated feldspars nanocoated with only 1–2 percent of the cheaper reactive metals. "Water splitting involves two chemical reactions—one with the hydrogen atom and one with the oxygen atom—to cause them to separate," Professor Sun said. "This new nanocoated material triggered the oxygen evolution reaction, which controls the overall efficiency of the whole water splitting process," he said. more at link................. the paper: https://onlinelibrary.wiley.com/doi/10.1002/aesr.202170018 In Situ Growth of Transition Metal Nanoparticles on Aluminosilicate Minerals for Oxygen Evolution: Abstract: Oxygen Evolution Reaction: Earth-abundant and environmentally friendly aluminosilicate minerals are considered promising alternatives to develop cost-effective energy conversion and storage devices. In article number 2100057, Hong Peng, Ziqi Sun, and co-workers, propose an in-situ growth of transition metal nanoparticles on commonly available feldspar minerals that can be used for promoting electrocatalytic oxygen evolution reaction activity. :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: article extract: "Australia's abundance of aluminosilicate and the simplicity of this modification process should make industrial scale production of this new catalyst easy to achieve," Professor Sun said. ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: That could indeed be a game changer, and one that could throw ScoMo in at least in some sort of reasonable light.
