  • NASA jumps on algae wagon

    From Discovery Channel

    Take some NASA-developed plastic membranes, add algae and municipal waste water and float it out to sea. What have you got? An environmentally friendly alternative to U.S. dependence on foreign oil, says one NASA scientist.

    Jonathan Trent, a researcher at NASA’s Ames Research Center in Moffett Field, Calif., sees algae farmed at sea as a win-win-win scenario: The plants are oil-rich and easy to grow; sea-based nurseries leave land free for food production; and the process should take out more carbon from the atmosphere than what it puts in.

    As an added bonus, the system purifies waste water now being pumped into the ocean.

    “What we’re doing is closing the loop in our own spaceship Earth environment,” Trent told Discovery News. “The only catch is no one’s ever done this before.”

    Algae has become one of the hotter commodities in the quest for fossil fuel alternatives, said Michael Frohlich, a spokesman for the National Biodiesel Board, a Missouri-based trade organization.

    Traditionally, algae is grown outdoors in large tanks of moving water, or inside bioreactors. The plants produce far more oil per acre than other crops, such as soybeans. Algae farming does, however, have a few technical hurdles to overcome, such as how to efficiently drain the water in which the algae grows, added Biodiesel Board technical adviser Alan Weber.

    Trent’s plan is to grow freshwater algae in nutrient-rich waste water inside semi-permeable plastic membranes. The natural salinity of the ocean will draw the freshwater out, retaining the plants and nutrients. The membranes prevent saltwater from getting inside and killing the plants, while ocean waves keep the algae mixed and healthy. The process treats the sewage water, which is then released into the ocean, and after the algae is harvested, the plastic bags can be recycled.

    The concept already has been demonstrated in laboratories, in part supported by $400,000 from Google earmarked for NASA sustainable energy projects. This week, the city of Santa Cruz expressed support for letting its municipal waste water be used in a pilot demonstration project in the Pacific Ocean, Trent said. The project also is under consideration for an $800,000 alternative energy grant from the state of California.

    “The big problem is going to be scaling it up … and figuring out how to deal with storms at sea,” Trent said.

    “But this country is good at engineering things,” he added. “To quote Harry Truman, ‘There’s no limit to what you can accomplish if you don’t care who gets the credit.’”

    An offshore algae farm could have some serious environmental issues, points out Carmela Cuomo, a marine scientist at the University of New Haven in Connecticut who is researching algae strains for biofuel use.

     

    “I’m not knocking the idea, but I’d want to know a lot more about it,” she told Discovery News.

    Cuomo said waste water that has been treated enough to be dumped into the ocean probably wouldn’t have enough nutrients for algae to thrive, and untreated waste water could pose a threat if the membrane should rip. She also pointed out that the algae farms would have to be fairly close to the ocean’s surface for sunlight to penetrate, which could be an issue for boaters.

    The main problem with algae, whether grown on land or sea, is how to get enough of it. “To be able to replace a Shell (Oil Co.), you’re going to need a lot of algae.”

  • China exposes Rudd’s 25% climate fig leaf

    “It was in complete breach of the Kyoto Protocol and all negations since
    – seriously undermining his first act as Prime Minister, which was to
    sign Kyoto with great fanfare.”
    “The bargain of Kyoto was that developed countries accept and meet
    mandatory reduction targets before developing countries took on
    mandatory targets.”
    “By making Australia’s target 25% conditional upon developing countries
    accepting a mandatory target of 20% below business-as-usual, Mr Rudd
    knew full well he was putting up conditions that would never be agreed.”
    “As Sue Wei has indicated today, Australia going against the spirit of
    the Kyoto Protocol and the subsequent Bali roadmap, will see increased
    anger and frustration in developing countries and undermine the
    prospects of a global agreement.”
    “Kevin Rudd was happy to get the accolades in Bali by ratifying the
    Kyoto Protocol, but is clearly not happy to take the responsibilities,
    and do the heavy lifting, that his signature implied.”
    Senator Milne said the rest of the world would see straight through what
    Australia was doing.
    “Why should China accept climate demands by Australia, when Australia
    remains  one of the highest per-capita emitters in the world?”
    “Why will the European Union accept that developed countries cut their
    emissions by 40% in aggregate, but that Australia should not take its
    fair share of that cut because Mr Rudd wants to protect the polluting
    coal industry?”

  • Transparency of acq and cost per house

    2) Good question.  Questions can be asked about the $6bn at Senate Estimates C’ttee time in Canberra, but the buck has been quickly passed to state govts, so the questions will need to be raised in state parliaments by vigorous opposition parties.
    2-1) The ‘Reverse Garbage’ building at Addison St, Marrickville has been built with straw bale.  Also has a full water tank.  Not sure about multi-storey, multi-residential structural engineering calculations in straw bale though  ; )
    Cement is also highly energy-intensive to produce.  Interestingly, a new ‘green’ cement made from volcanic fly ash called ‘pozzolana’ has been rediscovered recently in Cuba due to shortages — it resembles the cement originally discovered by the Romans and used 2,000 years ago, and takes much less energy to produce than Portland cement — and the cement is also hardier and less likely to get concrete cancer!  So a green future for cement…  http://en.wikipedia.org/wiki/Pozzolana
    2-3) It would be interesting to investigate what the ratio will be of new build bought directly from developers against purchasing existing privately held dwellings, and when the new builds were approved and built.  Entire blocks of flats are put up for sale fairly often, but not that many people have $2-3M lying around unleveraged by borrowing to spend on such an acquisition, so it shouldn’t be too hard to acquire some of these either.  The state govt will have to advertise for such vendors to come forward to bring it to their or their accountant’s attention — above and beyond one newspaper article.  After all, they’re advertising the FHOB on the sides of buses…
    Cheers,
    Sean

    Exactly what is the cost per house? 
            
    At just $1 Billion by NSW Govt:
        
    Cost per house              =  $1,000,000,000  /   9,000 houses
                                      =  $   111,111      per         house     
         
          
    What $ value from  Federal    $6,000,000,000                      for NSW?   
               
    [ 1-1 ]
    Why am I asking that The Greens check the arithmetic?  
         
    Because, I am in the middle of Audacity of Hope – Barack Obama,
    with  many unsavoury insights from USA that sadly fit Oz system;
    which includes a reference to dodgy costing.

    How do The Greens ensure a transparent process for this “acquisition of public housing”?
          
     ~  What if a Co-op of public spirited citizens offered to look in to, and even drive
         the process?
                
    [ 2-1 ]
    Ideally, Govt. should get a few public servants/Architects in to Green Housing/ allocate
    some land and do straw-bale mud houses – per my Permaculture class teacher a 8.5 score
    against normal concrete that score 2.
        
     ~  That’s all I know – I have been in a small straw bale house, and it felt good.
         I am yet in my 2nd class – introductory level.
         Houses are probably covered at Advance Level course – but,
         Permaculture orgs would have experts who wish these houses are in wider use, I feel.
         Humans did live in houses before concrete.
         And, old mud houses still stand in dessert ruins.  
         
     ~  Probably can build a straw bale house with just the first home owner grant!
         
     ~  Anybody wants to run a project/work bee re Greens stance – I offer my
         voluntary services as a willing researcher  for a good cause.
        
    [ 2-2 ]
    Nice if they start with old houses either abandoned or in Public Trustee care needing
    renovation etc.
         
    [ 2-3 ]
    Or, this is one way of unloading all the unsold developer housing with ALP donations
    already costed in to it. 
        
    If no proper process, public funds will cover another price hike to cover funding
    a snap election called in one of PM Rudd’s tantrums – when they are unsuccessful
    in having their way – all the way.
                      
    At the least we should watch out for an ALP’s already set-in-stone plan to wipe-out
    the  allocations in a worst possible way.
             
              
  • Australia commits $2m to ‘Amazon of the Seas’

     

    Environment Minister Peter Garrett says the Australian aid money will mainly support programs in coastal communities in Indonesia and Papua New Guinea.

    “This region is the Amazon of the Seas and we recognise how important it is that concerted regional action is taken to secure the health of the ocean environments,” he said.

    “It’s about food security. It’s about the livelihood of hundreds of millions of people in this region. It’s also about recognising how critical the health of the ocean environment is.

    “We want to see some support go in the first instance to Indonesia and Papua New Guinea.

    “We want to provide the opportunity for additional information learnings, for communities that will be doing this work, and we want to see strategies in place which will really start to deliver the on-ground actions which are necessary to protect the coral triangle itself.”

    Conservationists have backed the plan, with WWF director general Jim Leape saying the regional agreement is a landmark event.

    “What comes out of this commitment is a plan of action which allows, mandates, the ministers, ministries in each of these countries to work together to begin to conserve the tuna stocks that are so important here,” he said.

    “Also to begin to save the endangered sea turtles that live here, to begin to better manage the coastal ecosystems on which so many of their people depend.”

  • Beach bought for hard headed birds

    Related story from the UK Guardian

    Maleos – chicken-sized birds with black helmet-like foreheads – number from 5,000 to 10,000 in the wild and can only be found on Sulawesi island. They rely on sun-baked sands or volcanically-heated soil to incubate their eggs.

     

    The US-based Wildlife Conservation Society said it has teamed up with a local environmental group to purchase and protect a 14-hectare (36-acre) stretch of beach in northern Sulawesi that contains about 40 nests.

     

    The environmental groups paid $12,500 for the beach-front property on remote Sulawesi, one of Indonesia’s 17,000 islands, to help preserve the threatened species.

     

    “The protected area is already helping raise awareness about this bird,” said John Tasirin, WCS programme coordinator on the island, adding that is especially significant because humans are the greatest threat to the maleo’s survival. Villagers often dig up the eggs and harvest them for food, he added.

     

    The maleo, which has a blackish back, a pink stomach, yellow facial skin, a red-orange beak, lays gigantic eggs that are then buried in the sand or soil. The chicks hatch and climb from the ground able to fly and fend for themselves.

    “The population of maleos are decreasing quite steadily,” Martin Fowlie of the UK-based BirdLife International said of their new white-sand beach. “So any protection is going to be a good thing.”

     

  • An Early Double Dissolution?

     

    Turning the ‘Alcopops’ legislation into a trigger for a double dissolution provides the government with an alternative path to pass the legislation after an election. But more importantly it provides the option of a double dissolution at any time.

    If the government has key budget measures or the CPRS legislation blocked, the government can use the ‘Alcopops’ double dissolution trigger to frame an early election on the basis of the Senate obstructing other legislation. A double dissolution trigger is a mechanism to achieve an early election, not necessarily the main issue for an early election.

    In the current situation, the government’s first option would be to have its ‘Alcopops’ legislation passed into law. Its second choice would be to accept the double dissolution trigger it has been provided with and liberally use it as a threat to get the Senate to pass other government legislation.

    Its third option would be to call a double dissolution election, though the current state of opinion polls and the predicted path of the economy must mean that some in the government will see using the double dissolution trigger to call an election is the second rather than the third option.

    The mechanics of the constitution on early elections are clear in broad outline. The House of Representatives has variable terms, the Senate fixed staggered terms. Where the two chambers are in conflict, Section 57 of the Constitution is a deadlock resolution provision allowing for a double dissolution of both the House and the full Senate.

    The current House was elected on 24 November 2007. Its term is for three years timed from its first sitting after the election, 12 February 2008. So if the government does not call an earlier election, the House of Representatives will expire through the effluxion of time on 11 February 2011. Under the timetable for elections set out in the Constitution and the Electoral Act, the last possible date for a House election is 16 April 2011.

    However, the government can request a House election at any time. The government could request an early House election as a way of claiming a new mandate to overcome Senate obstruction. All the Prime Minister would have to do is request an early election stating his reasons, and the Governor-General would almost certainly assent to the election.

    But the Governor-General could only issue writs for a House of Representatives election. The Constitution would prevent the issue of writs for a half-Senate election. Section 13 of the Constitution states that writs for a half-Senate election can only be issued in the last year of a Senate’s term. This means that writs for the next half-Senate election cannot be issued before 1 July 2010. The first possible date for a half-Senate election is 7 August 2010. There cannot be a normal election for the House combined with half the Senate before 7 August 2010, only a double dissolution or separate House election.

    On a technical note, the fixed Senate terms only apply for the 72 State Senators. The terms of the four Territory Senators are provided for in legislation. Their terms are maximum three years, with the terms tied to the terms of the House of Representatives. An early House election would also be for the four Territory Senators, though it would almost certainly return one Labor and one Coalition Senator for each Territory, the result that has occurred at every election since 1975.

    The only way that the government can change the Senate numbers before 1 July 2011 is to call a double dissolution. A double dissolution is a deadlock provision designed to allow the House of Representatives to overcome the blocking power of the Senate. It allows the government to force the whole Senate to the electorate at once, breaking the Senate’s fixed term and changing the Senate numbers.

    There is little doubt the government would find this option attractive. The Coalition currently has 37 Senators, Labor 32, with 5 Greens, Senator Xenophon and Family First’s Steve Fielding. On current numbers, the Coalition need to lure only one of the cross-bench Senators across the aisle to block legislation.

    A double dissolution would almost certainly reduce the Coalition to 32-34 Senators, even less if current opinion polls are to be believed. Labor would probably gain Senators and stand a strong chance of gaining a majority of seats in conjunction with the Greens. Senator Xenophon would be re-elected, perhaps with a colleague from his ticket, while Senator Fielding would be unlikely to win re-election, ending his term which currently runs until June 2011.

    However, by reducing the quota for election from 14.3% to 7.7%, a double dissolution could also bring into the Senate a rag-tag collection of unknown Senators from micro-parties, elected thanks to the vagaries of the Senate’s preferential voting system.

    The double dissolution provisions are contained in Section 57 of the Constitution. It states that a bill must first be passed by the House and then be rejected, fail to pass or be unacceptably amended by the Senate. After a period of three months, the same bill must be passed by the House and then again be blocked, fail to pass or be unacceptably amended by the Senate. This provides a trigger which allows the Prime Minister to request a DD. The trigger does not have to be used at once, but must be used before six months from the end of the term of the House. So the announcement of a dissolution for a DD must take place by 11 August 2010, meaning that a double dissolution could take place as late as 16 October 2010.

    After a DD, the government must again present the legislation, and if it is again rejected by the Senate, then a joint sitting of the two Houses can be called under Section 57 at which legislation can be passed by both chambers voting together. The only time a joint sitting under this provision has been held was in 1974 when the Whitlam government passed four major pieces of legislation that had previously been blocked by the Senate.

    The ‘Alcopops’ legislation passed the first test of the double dissolution mechanism on 18 March when it was defeated in the Senate. By trying to pass the legislation again after 18 June, the government meets the three month delay requirement of Section 57. If the ‘Alcopops’ bill is then defeated in the Senate, the government has a trigger to request the Governor-General to issue writs for a double dissolution. It is a trigger the government does not have to use at once but could put away to be brought out from time to time as a threat to the Opposition in the Senate, or to unveil for real in asking the Governor-General for a double dissolution.

    Again it should be stressed that in re-introducing this legislation in a manner that allows it to become a double dissolution trigger does not mean the government is about to call an election. Introducing the ‘Alcopos’ bill in this manner increases the pressure on the Senate to pass the legislation, using the threat of an early election to force a legislative ‘blink’ from the Senate.

    Also, if the government does achieve a double dissolution trigger, it does not mean it is about to call an early election. Yes the government is well ahead in the opinion polls. Yes the budget reveals that the economy may be in a worse position in the second half of next year when the government is due to face the electorate. But we have seen in the past that governments that call early elections have seen enormous opinion poll leads disappear as an election forces voters to focus on the real choices at hand.

    An additional problem with an early election is the fact that redistributions are currently under way in both New South Wales and Queensland. This does not make an early election impossible, but does make it administratively messy.

    Given an election in September/October 2010 has always been the government’s preferred option, having a double dissolution trigger may actually be a useful option for the government. A double dissolution in October 2010 may be a preferable option to a normal House and half-Senate election.

    Holding a double dissolution rather than a normal half-Senate election may give the Labor Party a better position in the Senate.  No doubt some Labor number-crunchers have already looked at that option. But more importantly, a double dissolution would change the Senate at once, where under a half-Senate election, Labor would still be at the mercies of Senator Fielding and the Opposition through until June 2011.
