  • Visionary spruiks floating bridge plan Date

    “DISMANTLE OUR COATHANGER!!!! Built in the 1930’s along with the Bunnerong Power House by depression labour. This must take the role of idiotic idea of the year. Chinese Labour?? A new harbour crossing is vitally needed, but this idea takes the cake”

    Moving the bridge

    A proposal by Aspire Sydney to replace the Harbour Bridge to increase the traffic and rail capacity.

    Video will begin in 1 seconds.

    Dismantling the Sydney Harbour Bridge and floating in a new double-deck version built overseas sounds like a plan hatched over beers at the pub. But one man says it should be reality.

    Former federal Liberal MP Ross Cameron approached the state government with the radical proposal, which he says would solve Sydney’s worst transit ”choke point”.

    Even better, it could be built using Chinese labour, at a fraction of the cost of the proposed $10 billion second harbour rail crossing, Mr Cameron says.

    “If you left [the bridge] it would get increasingly dangerous and more bits of it will start falling off,” he said, referring to an incident in March when loose metal plates caused commuter chaos.

    The bridge “needs three times as much rail capability and twice as much road capability”.

    He would seek to form a public-private partnership.

    It forms part of a grander plan, rejected by the state government last November, to build the M4 East motorway in exchange for the rights to develop the rail corridor between Central and Strathfield. Thousands of international workers would rebuild kilometres of rail lines underground and assemble at least 150 skyscrapers, prefabricated in China. Materials would be moved to the construction site on overhead conveyor belts from a new port near Glebe.

    Mr Cameron would also turn historic Fort Denison into a cruise passenger terminal, connected to the mainland via a tunnel.

    The former Macquarie banker wants the government to fully evaluate the proposal.

    He says he met NSW’s top transport bureaucrat Les Wielinga, who asked him to “please include the bridge” when he submitted the plans. A consortium known as Aspire Sydney would procure a new two-deck bridge from an overseas manufacturer before floating it “whole or in pieces to Sydney Harbour”.

    A spokesman for Mr Wielinga said he advised Mr Cameron to lodge the plan as an unsolicited proposal “if he felt it had promise”. The Premier’s Department rejected the Aspire Sydney proposal, saying it “did not present a commercial or financial proposition for [the] government to consider.

  • How crowdsourcing and open innovation could change the world

    How crowdsourcing and open innovation could change the world

    Tapping into the ideas offered by large numbers of people seems a smart way to solve some of our most pressing problems

    Historically, technological breakthroughs have been led by the innovations of the few with access to the resources and platform to influence, but something exciting is happening on the worldwide web that is turning this precedent on its head.

    Crowdsourcing, as defined by Wired Magazine, represents “the act of a company or institution taking a function once performed by employees and outsourcing it to an undefined (and generally large) network of people in the form of an open call.”

    Although it may seem like it is a new phenomenon, the basic practices of crowdsourcing and open-innovation have been around for centuries. In fact, the Oxford English Dictionary started out in the late 18th century as an open appeal by Professor James Murray to collate idioms and phrases from thousands of volunteers around the English-speaking world.

    As time has moved on, the internet has facilitated, expanded and accelerated the interactions behind crowdsourcing. Crowdsourcing and open innovation websites allow people from all cultural, economic and educational backgrounds to collaborate on ground-breaking technology.

    Kickstarter is probably the most famous example of an online crowdsourcing platform. Since its launch in 2009, it has grown to become the largest funding platform for creative projects, with over 4.2 million people pledging in excess of $652m to fund over 43,000 projects.

    Outside the domain of raising cash for iPod docks and Bluetooth-enabled watches, a number of other online crowdsourcing platforms have sprung up in recent years to solve any number of different societal and technological problems. OpenIDEO hosts a small number of philanthropic competitions and asks their online community to come up with new design solutions to societal problems. Kaggle offers monetary rewards, jobs or consulting opportunities to data scientists that can make sense of problems with large data sets. One of the grandfathers in this arena is Innocentive which has been crowdsourcing solutions to problems since 2001. Innocentive’s community of “solvers” tackle problems spanning engineering to life sciences, and business to IT, with sponsored prizes in the past from the likes of Merck, Nasa and The Economist.

    Why are businesses getting involved?

    Until recently, “traditional” corporates have watched open innovation and crowdsourcing initiatives from the sidelines with very few getting directly involved. There are signs that this is changing; with the economic downturn in recent years, more and more businesses have been turning to outsourcing as a cost-saving measure.

    Outsourcing to a cheaper labour force has its advantages (and disadvantages), and crowdsourcing can often also save businesses money. However, where crowdsourcing excels is in opening up a large workforce with a diverse set of skills and experiences, as within the crowd you’ll find domain experts that are notoriously difficult to tap into by “conventional” means. Having access to that kind of diversity and micro expertise at scale can only be a good thing for business.

    Starbucks has “My Starbucks Idea” which invites its customers to suggest improvements for anything from new flavours for drinks to the music it plays in its stores. There is no monetary reward or financial compensation, yet Starbucks has over 100,000 ideas on the site.

    One area in which open innovation and crowdsourcing is emerging as a crucial tool is in the development of sustainable technology. In May, for the first time in human history, the concentration of CO2 in the atmosphere hit 400ppm (parts per million). By 2050, there will be 9 billion people sharing our planet and in the next 20 years, the world’s middle class will grow from less than 2 billion to more than 4 billion. This growth will be coupled with enormous demand for resources.

    Crowdsourcing a clean tech revolution?

    The time has come for a clean revolution: a swift, massive scale-up of clean energy and infrastructure, and of smart technologies and design. There are rich rewards for those that pioneer the revolution; research by Google in 2011 found that breakthroughs in clean-tech innovation could generate an extra $155-244bn (£102-160bn) of GDP per year in the US from 2030 if the right investments are made now.

    There are global businesses that have recognised the potential of the low carbon economy and are utilising crowdsourcing and open innovation websites to realise the technologies these online communities create through collaboration. The message that sustainability and profitability are not mutually exclusive is beginning to resonate.

    We truly believe that crowdsourcing and open innovation have the potential to solve the biggest issues facing society. Some of the biggest leaps in technologies and innovation in science have come from approaching old problems with fresh perspectives not constrained by old dogmas. It took a chemist to overthrow the old tenet in biology that genetic information only flows in one direction (DNA > RNA > Protein), and it revolutionised our understanding of how viruses like HIV work and resulted in the awarding of not one, but two Nobel Prizes.

    We look to science more and more to solve these big problems and co-ordinating the efforts of large crowds made up of individuals that each have something different to offer and can build on each other’s ideas seems a smart way to solve them.

    Ben Ferrari is director of corporate relations at The Climate Group and Mehmet Fidanboylu is director of product and co-founder of Marblar.com, which crowdsources market applications for emerging and dormant technology.

  • So shale gas could meet demand for 40 years. What then?

    So shale gas could meet demand for 40 years. What then?

    Britain’s new gas capacity is much hyped, but the fracking path will most likely lead to the lights going out regardless

    For a moment, let’s take the shale gas evangelists at their word. Britain has stumbled on a pile of carbon cash in its cellar, the energy equivalent of finding a stack of ugly but valuable china in the attic. With North Sea oil and gas in decline and global markets volatile and pricey, suddenly there seems a sure way to deliver the government’s promise of building 40 new gas power stations. By odd coincidence, newly estimated gas resources in the Bowland shale could meet our demand for gas for 40 years.

    Wonderful for some, but then what? Fast forward to July 2053 and where will we be? We will have a household and national energy infrastructure hopelessly dependent on an exhausted fuel source, and a climate pushed past the point of no return, warming catastrophically due to the burning of fossil fuels. The government’s own committee on climate change has pointed out that this would likely put the UK the wrong side of legally binding commitments to reduce emissions.

    Communities that took the £100,000 bribe to accept a gas-fracking well and the parsimonious 1% of revenue will end up feeling like every other community around the world touched by the resource curse: wondering what happened to them. They will be left with the environmental legacy of extraction, locked in to ever costlier fossil fuels, precious little in pocket and with children growing up in a world marked by climatic upheaval.

    Worse still, if we believe the Ofgem warning about an energy supply crunch due in 18 months, none of this much-hyped new gas capacity will be ready in time to help regardless.

    And there are many other reasons for caution. Policymakers have been hypnotised by the impact on gas prices of shale developments in the US, but this stands to be a misleading and short-lived result of an immature market. There, a gas dash has flooded the market with new supply, pushing prices down. But unlike conventional gas, shale gas fields decline more rapidly, and there’s evidence that in the US companies have concentrated on “sweet spots”, whereas the broader fields used to justify upbeat estimates are much less productive.

    When this was realised, one of the largest American fields, the Marcellus shale in the eastern US, saw an 80% downward revision of its undiscovered, technically recoverable reserves. Similar bad news comes from other hyped new sources such as those in Poland. Industry analysts Bernstein Research concluded that “data from Poland’s shale gas wells validate our concerns about European shale gas: poor flow rates in over-pressured, hard-to-develop shales”.

    If climate change and the economic vulnerability of fossil fuel dependence are insufficient reasons to think twice about deepening our fossil fuel addiction, perhaps we should also remember that, wherever the oil industry treads, conflict and corruption tend to follow. From the Middle East to Africa a story of red blood, black carbon and cold money repeats itself.

    But it doesn’t stop there. Louisiana, dubbed America’s “petro-state”, hasn’t escaped the resource curse of oil and gas. The Washington Post pointed out not long ago that, instead of prosperity, the industry had brought “dependency, corruption and an indifference to environmental damage”. And, far from improving the lives of its people, that state has some of the worst health and social indicators, such as violent crime, in the country. For all the counties sitting on top of shale beds, this may be further cause to pause before taking the shale pound.

    The alternative for Britain has been clear, yet ignored, since the need to stimulate the economy after the financial crash of 2007-2008. It involves: large-scale investment in a green new deal; a carbon army of green-collar workers to make the nation’s draft buildings energy efficient; the building and maintenance of an efficient, more decentralised and renewably powered energy system; the remaking of our transport system – and more.

    Obvious efficiency measures such as overnight electric light curfews in city office blocks might help, sending an important signal, and the government could impose a demand reduction obligation on the utilities too. This is not the embarrassing failure of the current small insulation programme dubbed a green deal, but a bold plan for necessary and rapid transition to a modern, more secure and convivial economy. It stands a far better chance of keeping the lights on too.

  • California set to swelter in heatwave temperature of 53C

    California set to swelter in heatwave temperature of 53C

    Updated 37 minutes ago

    A potentially deadly heatwave is expected to bear down on the United States’ south-west, with temperatures in California’s Death Valley forecast to hit 53 degrees Celsius.

    The severe heat will be only slightly lower than the hottest temperature ever recorded on earth – 57 degrees in the same location 100 years ago.

    Similar temperatures are predicted in the states of Arizona and Nevada.

    Weather forecasters say the mercury could reach 40 to 50 degrees Celsius in the deserts in southern Arizona.

    Cities in the region are opening cooling centres and officials fear the heat could delay air travel.

    The National Weather Service has issued an excessive heat warning that is current for the entire weekend.

    “Exceedingly high temperatures can cause heat-related illness, including death,” it said.

    The agency added that residents without air-conditioning are most vulnerable.

    It said the city of Phoenix is expected to reach 48 degrees Celsius, further increasing the risk of heat stroke and exhaustion.

    ‘Too hot to touch’

    Arizona resident Michael Fedo says the heat feels like an invisible wall that has forced his family to install black-out shades on every window in their house.

    “It’s almost the same thing which you get when you have your oven pre-heated and you open the oven door and you get that wash of heat over you – times 100,” he said.

    “As soon as that door opens it’s there, it’s always there, it’s just permeating to the core of your being.”

    Another Arizona resident, Ray Huffer, says the heat is making some things too hot to touch.

    “The metal that you touch on the door to get in your house, you need to have a cloth on it, you have to have a towel with you to touch the steering wheel,” he said.

    “An extended heatwave like this, five, six, seven days, the workers can’t go roofing, asphalt doesn’t harden, all kinds of economic things have to literally stop.”

    Kevin Rudd appears capable of neutralising Opposition Leader Tony Abbott’s relentless attack on the government’s mishandling of asylum seeker boat arrivals.

    Polling in key Labor seats that had turned their backs on the ALP under Julia Gillard reveals a surprise turnaround in confidence in Mr Rudd to find a solution on boats.

    Most of my friends are younger folk.

    As refugee policy became the first flashpoint between the rebadged Labor government and the Coalition, a Fairfax-ReachTEL poll of four Labor electorates in Sydney and Melbourne found voters believe Mr Rudd is just as well equipped as Mr Abbott to slow maritime arrivals.

    A survey of voters in Blaxland and McMahon in western Sydney, and Chisholm and Maribyrnong in outer Melbourne, found a 50:50 split on who was the best leader for the task.

    The result will be of serious concern to Liberal strategists who had made deep inroads into once-safe Labor seats by focusing on Labor’s handling of the issue under Ms Gillard – and Mr Rudd before her.

    Confidence in Mr Rudd is more surprising considering 74 per cent of the voters in those seats blame Labor for the morass.

    In Blaxland, held by Home Affairs Minister Jason Clare, 52 per cent of the 625 people polled by phone on Thursday said Mr Rudd was best able to handle the issue.

    In Treasurer Chris Bowen’s seat of McMahon, Mr Abbott led by a whisker on the issue, with 50.5 per cent of people backing him. In Bill Shorten’s seat of Maribyrnong, 55 per cent backed Mr Rudd.

    Election rally speeches delivered in Melbourne on Saturday by former prime minister John Howard and Mr Abbott indicated the Coalition would step up the attack on Labor over boats.

    Boat arrivals have caused concern among migrants, many of whom see themselves as having come in ”through the front door”. Mr Rudd and Foreign Minister Bob Carr have signalled a ”harder edge” on processing of refugee applications.

    Mr Howard branded Mr Rudd the ”great policy chameleon of Australian politics”, pointing to the Prime Minister’s various promises to tow back boats in 2007 and warnings to his colleagues not to lurch to the right and the left on the issue.

  • World’s first hybrid wind/current generator could generate double the power

    World’s first hybrid wind/current generator could generate double the power

    SKWID wind and current generator

    Combining a three-bladed Darrieus turbine on top, a Savonius turbine underneath, and a generator in between, the SKWID power generation concept is claimed to be the world’s first hybrid system “capable of maximizing the harvesting of ocean energy from wind and current”.

    The SKWID, from the Japanese company Mitsui Ocean Development & Engineering Company (MODEC), is designed to capitalize on the energy potential available both in the winds above the ocean, and in the currents flowing beneath the waves. The device uses an omnidirectional Darrieus wind turbine sitting 47 meters above the sea on one end of a vertical shaft, with a different type of omnidirectional turbine design, a 15 meter diameter Savonius, spinning at the other end under the surface.

    The Darrieus wind turbine efficiently harnesses the ocean wind: The omnidirectional Darrieus turbine rotates regardless of the wind direction. Due to the location of the generator, the system has excellent stability with a low center of gravity, as well as excellent maintainability with easy access. The Darrieus’ rectangular swept area catches twice as much wind when compared to the circular swept area of typical onshore wind turbines of the same diameter and is therefore capable of delivering twice as much power from a single installation – far more power from the same wind farm areaThe Savonius current turbine harnesses the current: The split-cylinder-shaped buckets of the Savonius current turbine can harness any weak current and will rotate in one direction regardless of current direction. This turbine is insensitive to marine growth on the buckets and is harmless to the marine ecosystem, as it rotates slowly at the speed of the current. – MODEC

    The floating unit is said to be stable and self-righting, thanks to a gimbal-like support structure that isolates the generator unit from the motion of the waves, as well as the underwater turbine acting as a ballast or keel. According to CBS News, a prototype SKWID unit will be deployed off the coast of Japan this fall.
