    Music Thread 3

    Before there was Narara there was Sunbury. Before there was Sunbury there was Ourimbah. The festival drew 6,333 patrons according to Ian McFarlane, but Bernie Howitt's 1994 account states that there were about 6000 on the first day, but that by the second day there were some 10,000 people on site. Bernie btw is a Foundation member and to my mind knows more about music than Glenn A Baker Bernie Howitt Rock Through History (Longman Cheshire, 1989) https://www.udiscovermusic.com/stories/ourimbah-1970-australias-first-rock-festival/

    Climate Change & Alternative Energy

    https://www.abc.net.au/news/2019-04-24/electric-aircraft-transport-disruption-coming-need-to-plan-ahead/11041940 Move aside electric cars, another disruption set to occur in the next decade is being ignored in current Australian transport infrastructure debates: electric aviation. Electric aircraft technology is rapidly developing locally and overseas, with the aim of potentially reducing emissions and operating costs by over 75 per cent. Other countries are already planning for 100 per cent electric short-haul plane fleets within a couple of decades. Australia relies heavily on air transport. The country has the most domestic airline seats per person in the world. We have also witnessed flight passenger numbers double over the past 20 years. Infrastructure projects are typically planned 20 or more years ahead. This makes it more important than ever that we start to adopt a disruptive lens in planning. It's time to start accounting for electric aviation if we are to capitalise on its potential economic and environmental benefits. What can these aircraft do? There are two main types of electric aircraft: short-haul planes and vertical take-off and landing (VTOL) vehicles, including drones. The key issue affecting the uptake of electric aircraft is the need to ensure enough battery energy densityto support commercial flights. While some major impediments are still to be overcome, we are likely to see short-haul electric flights locally before 2030. Small, two-to-four-seat, electric planes are already flying in Australia today. Space to play or pause, M to mute, left and right arrows to seek, up and down arrows for volume. VIDEO: A look inside Australia's first electric plane (ABC News) A scan of global electric aircraft development suggests rapid advancements are likely over the coming decade. By 2022, nine-seat planes could be doing short-haul flight (500-1,000km). Before 2030, small-to-medium 150-seat planes could be flying up to 500 kilometres. Short-range (100-250 km) VTOL aircraft could also become viable in the 2020s. If these breakthroughs occur, we could see small, commercial, electric aircraft operating on some of Australia's busiest air routes, including Sydney-Melbourne or Brisbane, as well as opening up new, cost-effective travel routes to and from regional Australia. PHOTO: Possible short-haul electric aircraft ranges of 500km and 1,000km around Melbourne, Sydney and Brisbane.(Author provided) Why go electric? In addition to new export opportunities, as shown by MagniX, electric aviation could greatly reduce the financial and environmental costs of air transport in Australia. Two major components of current airline costs are fuel (27 per cent) and maintenance (11 per cent). Electric aircraft could deliver significant price reductions through reduced energy and maintenance costs. Short-haul electric aircraft are particularly compelling given the inherent energy efficiency, simplicity and longevity of the battery-powered motor and drivetrain. No alternative fuel sources can deliver the same level of savings. With conventional planes, a high-passenger, high-frequency model comes with a limiting environmental cost of burning fuel. Smaller electric aircraft can avoid the fuel costs and emissions resulting from high-frequency service models. This can lead to increased competition between airlines and between airports, further lowering costs. What are the implications? Air transport is generally organised in combinations of hub-and-spoke or point-to-point models. Smaller, more energy-efficient planes encourage point-to-point flights, which can also be the spokes on long-haul hub models. This means electric aircraft could lead to higher-frequency services, enabling more competitive point-to-point flights, and increase the dispersion of air services to smaller airports. While benefiting smaller airports, electric aircraft could also improve the efficiency of some larger constrained airports. For example, Australia's largest airport, Sydney Airport, is efficient in both operations and costs. However, due to noise and pollution, physical and regulatory constraints — mainly aircraft movement caps and a curfew — can lead to congestion. Holiday in the future Black-hole holidays, deep sea travel and shapeshifting beds in talking hotel rooms — step into tourism in 2030. With a significant number of sub-1,000km flights originating from Sydney, low-noise, zero-emission, electric aircraft could overcome some of these constraints, increasing airport efficiency and lowering costs. The increased availability of short-haul, affordable air travel could actively compete with other transport services, including high-speed rail. Alternatively, if the planning of high-speed rail projects takes account of electric aviation, these services could improve connectivity at regional rail hubs. This could strengthen the business cases for high-speed rail projects by reducing the number of stops and travel times, and increasing overall network coverage.

International air freight volumes have increased by 80 per cent in the past 20 years. Electric aircraft provide an opportunity to efficiently transport high-value products to key regional transport hubs, as well as directly to consumers via VTOL vehicles or drones. If properly planned, electric aviation could complement existing freight services, including road, sea and air services. This would reduce the overall cost of transporting high-value goods. Four airline breakthroughs Australians love travelling. But we're increasingly conscious of our wellbeing onboard these long-haul flights. Will advancements in technology help resolve this dilemma? Plan now for the coming disruption Electric aircraft could significantly disrupt short-haul air transport within the next decade. How quickly will this technology affect conventional infrastructure? It is difficult to say given the many unknown factors. The uncertainties include step-change technologies, such as solid-state batteries, that could radically accelerate the uptake and capabilities of electric aircraft. What we do know today is that Australia is already struggling with disruptive technological changes in energy, telecommunications and even other transport segments. These challenges highlight the need to start taking account of disruptive technology when planning infrastructure Where we see billions of dollars being invested in technological transformation, we need to assume disruption is coming. With electric aircraft we have some time to prepare, so let's not fall behind the eight ball again — as has happened with electric cars — and start to plan ahead.

    The lyrics to this song are unbelievably powerful, if you have lived this. My favourite uncle died at 49, essentially because he was an alcoholic. He never got over the war, left as a tea totter. When he came back from new Guinea he was an alcoholic. I don't think I ever saw him without a drink or sober. But he had the kindest heart and a brilliant mind.

    Julian Assange arrested by UK police

    "The British public know there is something wrong here when the whistleblower is in jail while the perpetrators are on TV" says former MP George Galloway who talks to In Question's Manila Chan as many in mainstream media stay mum on press freedom in Julian Assange case. Jeremy Corbyn opposes Julian Assange extradition to the US ... good stuff..

    Julian Assange arrested by UK police

    Sonar Nay this thread is about the jailing of Julian Assange... and he is not my poster boy . This is about a media company that has embarrassed both side of politics in the US and they want to shut him down. and sent a message to everyone in the world . IMO this is the biggest attack on freedom of the press in my lifetime and it has nothing to do with Assange's character, its about press freedoms.

    Julian Assange arrested by UK police

    sonar I am not mad at you but I am mad at the process that has you thinking the way you do.... its the same media types who have convinced half of Australia to not believe in what scientists say, who belittle any academic statement that does not suit them. You said "" I have never said anything about limiting the free press....never ever."" what effect other than having a huge effect on a free press is jailing Julian. ""Have I called for WikiLeaks to be shut down ? Have I called for any press to be shut down........NO I havent. I only criticised them .""" I accept that however your criticism has been about hacking and not hacking other countries, what I have tried to explain is they don't hack, people come to them and they have released heaps about other countries as well... it just not get the same coverage in the main stream press as has the US dumps. "The portion of the password Manning gave Assang to crack"... Barvo this actually makes me so so so so so so so so so so sad in the ways its been framed by those who want to punish nay silence him. I doubt in the history of a free press with insiders providing information to journalist that the journalist does not try and help the provider if they can. How do I use a fax, how do I use drop box, my guess is world wide every minute of every day a journalist helps their source. Finally on this aspect i.e. they broke a law in getting the information then close down the New York Times and Washington Post because in "The Pentagon Papers" & Watergate they broke the law.... yet we protected both the journalist involved and the institutions they work for. The framing of this by those in power is to convince people this charge is not about a free press and is about computer hacking is impressive and in overdrive.... anyone who believes that has been taken for a ride.

    Julian Assange arrested by UK police

    So your entire argument is he did not go after enough countries... and he hacked the information himself or Wikileaks did.. also if he is an arsehole as you believe why should that be a reason to stop a free press. OK OK OK ... maybe if I type this slowly you will read it slowly and understand at least this part. Wikileaks... DID NOT HACK.... PEOPLE CAME to Wikileaks with info ... Your argument seems to revolve around Wikileaks only hacked western countries. Wikileaks did not hack he was given the information. Secondly he has released information on released stuff on India and many South Amercian countries ... but from information given to him. Also the US court case is NOT repeat NOT please understand is NOT about hacking its a clever ruse by putting in a press release This is worth watching in time he explains what is in teh US court docs.... and its NOT hacking ... and he explains what Wikileaks is i.e. a publisher.
