    Nurses -striking for a safer health system for all New Zealanders.

    Labour – the party that puts eradicating M. bovis (that has no human health risk) ahead of patient safety.

              and if the nurses were happy, you’d be bitching about a poor m. bovis response.

                The response to M. bovis has been poor. But the blame for that largely rests with the last administration.

                Nevertheless, I don’t support Grant’s blank cheque approach and I’ve yet to see him explain why he is prepared to put that before patient safety?

                  Oh, that would be because nobody other than the occasional tory lickspittle is trying to play the health sector against the rural communities.

                    Don’t be silly.

                    Labour’s refusal to put more money on the table to further address patient safety concerns has now got many questioning Labour’s priorities when it comes to expenditure.

                  Nurses have been on the bones of their arses for the LAST NINE YEARS.Where was your concern for patient safety then TC? The biggest concern for anybody during Nats time was actually becoming a patient. Their health outcome was pretty poor by anybody’s standard. This Govt is doing it’s level best in the SHORT TIME it’s been in power to address everybody’s need. Give them bloody time. A surplus is only a surplus until it’s not.

                  • The Chairman …
                    12 July 2018 at 7:27 pm

                    My concern for patient safety didn’t change just because the Government changed. Unlike yours evidently.

                    Labour’s Budget Responsibility Rules are only a little softer than National’s fiscal position, which created the under-funding which Labour are finding their Budget Responsibility Rules are making difficult to address.

                    And the thing is, a lot of these problems will worsen (thus will become more difficult to correct going forward) at the slow pace Labour are moving. So best you join the outrage and start tooting for the nurses. Labour don’t have the luxury of having time to spare.

                    As for this Government’s surplus, the Government’s books are showing the surplus is almost half a billion more than was originally forecast. Moreover, Government debt is also tracking better than expected (see link below). So there is extra fiscal scope for the Government to consider improving wage offers

                    Moreover, why the concern about me? The issue here is the nurses dispute. Aren’t you concerned about that?

            MPI should be sued as should be the importer of the M.Bovine virus.

            That should pay for the medical funding shortfall.

            Now what about the $1 billion dollars spent now fighting M. Bovis?????

            Sue the ‘National Party’ for $1 billion, as the M.Bovine virus was alllowed to come here from 2015 we are told.??????

    All round the world as Governments, Parties, and Political Movements, turn to the Right, Mateao di Maio asks, will this rising Right Wing tide wash up on our shores?

    The US takes the far-right shift a notch further. Trump’s tolerance of those I would have no qualms calling Nazis is worrying. Last August, racist rallies in Charlottesville lasted two days without condemnation from the commander in chief.

    I’m sure there are not any more white supremacists in America today than there were, say, two decades ago. But now they’re marching without their hoods. And that’s because they’ve got permission from the president.

    Echoing 1930s Germany, recently migrant children were being stripped from their parents at the US border. And a flimsy executive order (a PR move on the president’s part, more than anything else) does little to end the crisis.

    It’s not just in the US that anti-immigration sentiment has taken hold. The global consensus on asylum seekers seems to be: “We don’t want you.”

    Academics and journalists alike are bewildered by how easily everyone has been blinded by “quasi-fascist” strongmen, in everywhere from Trump’s America to Erdogan’s Turkey. Victor Orban’s populist takeover in Hungary could never have happened, say, twenty years ago, as Eastern Europe still lay healing from their Soviet-era wounds. Over in Germany, Angela Merkel’s grand coalition is trembling under the weight of the EU’s “liberal” immigration policies.

    Feels like the skilful hand of James Shaw behind getting this group of leading businesses to commit to climate change target and to support the Climate Change Commission. More of major business are coming behind this Green Party initiative than are getting behind the New Zealand First Provincial Growth Partnership, and James Shaw doesn’t have $1billion dollars to roll around.

    https://www.nzherald.co.nz/business/news/article.cfm?c_id=3&objectid=12087184

    The launch will be today, and the Skytower will be lit up green as a signal of the commitment.

    Looks more and more that the results of the Climate Change Commission and resulting legislation will have a major backing fro business, making it far more likely that it will have crucial cross-parliamentary support.

    That would make the commitments truly intergenerational.

    Census 2018 has turned into a shambles with the lowest participation rate in over 50 years,” National’s spokesperson for State Services Nick Smith said. “The Government must figure out what went so wrong and how the serious flow on problems for the public sector can be rectified,” Dr Smith said.

    Many people still don’t have internet access or TV. I spoke to one person just after the census who had no idea one had just occurred.

    This is just what happens when the have/have not gap widens drastically.

        probably find the census was turned in well under budget, so that’s a plus for statsnz.

        That having been said, 90% is at the low end of barely acceptable, compensation from other sources or not. It’s a bit like the IDI probabilistic linking, which is simply a bodge to make up for the lack of a cross-department individual unique ID. And not a bodge that is appropriate for a lot of uses of government data.

      But, but, but… rail never makes a profit! So we must endure the traffic jams and the losses in productivity, and the high petrol costs, and the high petrol taxes because we need roads, lots of roads, and bigger roads, preferably massive motorways that make no financial whatsoever because I will be able to drive my imposing Porsche Cayenne or Ford Ranger aggressively on them and not indicate and basically have no care for anyone else on the road.

    Meanwhile, clean green New Zealand’s emissions are up by around 20% on 1990 levels.

    NEWS RELEASE: Climate pollutants fall below 1990 levels for first time ➡️ https://t.co/8FaHsL8rXD #AB32 #SB32Achievement roughly equal to taking 12 million cars off the road or saving 6 billion gallons of gasoline a year #ActOnClimate pic.twitter.com/bVRCGpX4vh— CARB (@AirResources) July 11, 2018

    Senate Bill 32, signed in 2016, requires the state to go even further than AB 32 and cut emissions 40 percent below 1990 levels by 2030—the most ambitious carbon goal in North America. The state’s annual emissions inventory helps keep the state accountable for meeting its emissions reduction targets. Highlights from the inventory published today include:

    • Carbon pollution dropped 13 percent statewide since a 2004 peak; meanwhile the economy grew 26 percent.
    • Per capita emissions continue to be among the lowest in the country. They fell 23 percent from a peak of 14 metric tons per person (roughly equal to driving 34,000 miles) in 2001 to 10.8 metric tons per person in 2016 (roughly equal to driving 26,000 miles). That is approximately half as much as the national average.
    • Carbon pollution dropped 3 percent between 2015 and 2016—roughly equal to taking 2.4 million cars off the road or saving 1.5 billion gallons of gasoline and diesel fuel.
    • The “carbon intensity” of California’s economy – the amount of carbon pollution emitted per $1 million of gross state product – dropped 38 percent since the 2001 peak and is now one-half the national average.
    • California now produces twice as many goods and services for the same amount of greenhouse gas emissions as the rest of the nation.

        And hydrogen development could lead to a major shift in energy supply.
        Exciting stuff!

      • Andre 11.2.2
        12 July 2018 at 4:38 pm

        This one has me a little suspicious. I’m wary that there may be some greenwashing going on here.

        The main industrial process for making hydrogen is steam reformation of natural gas. Which emits the carbon atoms in the natural gas as CO2 at the point of creating hydrogen. So sure, further downstream the hydrogen can be used for energy and it’s zero-emission, because the emissions have already occurred elsewhere. For almost all the potential users of hydrogen, the emissions from steam reformation of natural gas to hydrogen then using the hydrogen are greater than if the natural gas had just been directly used for the heat or to power an engine.

        Looking at the founder, it seems he’s closely linked to Todd Energy – who are big time owners of – guess what? Gas fields and production.

        Now maybe I’m a little too suspicious and he’s wanting to make a break from fossil fuels, is going to use some other technology, but is locating in Taranaki to tap into the oil and gas expertise there which overlaps strongly with the skills needed for hydrogen.

        We’ll see…

        • McFlock 11.2.2.1

          good observation

        • lprent 11.2.2.2
          12 July 2018 at 5:15 pm

          I know nothing about this project, however four points do occur to me:-

          1. Taranaki has the most concentrated knowledge in NZ of containing and transporting gas. That makes it a logical region to develop any kind of gas technology in NZ because many of the skills will shift to other gases.

          2. Depends what they are using the hydrogen for. Looks to me like you are presuming that it is for fuel? Why? Most of the hydrogen in use is for higher value chemical processes like ammonia production. At the scale that is implied by the amounts, it seems more likely that this is what it used for.

          3. Steam reformation isn’t the only process and isn’t the main process used for hydrogen fuel. It just happens to be the one used for the majority production of commercial hydrogen – mostly used in chemical processes.

          Electrolysis (ie power to gas) is a non-carbon process if it uses hydro or wind power. Wind power strikes me as being a likely reason to be around the Taranaki especially if they use offshore windfarms in the old gasfield areas. They have a existing infrastructure for offshore in Taranaki.

          4. Even if they do fuel development using steam on natural gas (in the absence of the required infrastructure for turbine farms), Taranaki is about the only place in NZ that can do some moderately efficient sequestration. Lots of empty gas fields.

          They won’t be doing commercial natural gas to hydrogen for fuel because it is way more efficient to just burn natural gas directly and that would be way better in climate change terms than burning more complex hydrocarbons like those in petrol or diesel fractions.

            12 July 2018 at 5:30 pm

            1: Yep. I alluded to that at the end of my comment.

            2: from b waghorn’s link: “During his visit to New Plymouth, Peters said a grant of $950,000 would be made to Hiringa Energy and its partners, which is seeking to develop zero emission hydrogen transport fuel.

            The funding will be used to scope the engineering and design of two hydrogen generation facilities, up to four mobile compressed hydrogen storage and distribution containers, and up to three hydrogen refuelling stations. ”

            Transport fuel is the stated objective of the project.

            3: The lack of mention how the hydrogen will be generated plus the founder’s links to Todd Energy plus the very careful wording talking about zero emission transport fuel but neglecting to state zero emission hydrogen generation combines to pique my interest.

            4: Maybe it’s just me, but if I were planning on introducing a major new technology like CO2 sequestration into empty gas fields, you can bet I’d be talking it up big time. But a brief intertoobz search turned up … crickets.

              Just thinking about the ways of storing and transporting raw hydrogen are hair-raising to even contemplate. Since talk of the hydrogen economy started, they haven’t exactly managed to figure out how to make it even moderately stable at normal atmospheric temperatures and pressures.

              In engineering terms actually generating the gas isn’t that much of a technical issue. I’d be much more interested in them figuring out how to make roads and refuelling stations less like high density explosion fields.

              If you wanted to try to develop a hydrogen based fuel infrastructure, then Taranaki is where you’d start it. Just trying to develop an end-to-end hydrogen system is going to damn hard regardless of the source of the fuel.

              Personally I’d think that developing EV’s and EV infrastructure would be a better idea. And in that case putting money into how to develop offshore windfarms would be a better idea. But that is best done from Taranaki as well.

                It’d be good to see a hydrogen dirigible for transTasman cargo now that automation makes unmanned ones plausible.

                  Helium is much better for dirigibles. The Zeppelins had to use hydrogen because at the time the US was the only significant producer of helium and they weren’t selling to anyone else.

                  One of the problems with hydrogen is it makes its way through just about any materials very quickly, and usually does bad things to the material’s structure and properties as it does so. Look up hydrogen embrittlement and permeability. I’ve yet to see a good explanation why, but I’ll speculate it’s because when a hydrogen atom loses its electron, it’s just a tiny naked proton which can move easily through just about any kind of molecular structure, whereas every other kind of atom will always have two electrons in an extremely stable filled first orbital shell, making it much larger.

                  So by the time you’ve beefed up your bags to hold the hydrogen for long enough, you’ve added quite a weight penalty over using helium.

                    thing is, hydrogen is plentiful and helium is not.

                    Helium is both expensive and finite. It also produces less lift.

                      It won’t be once the alien unicorns turn up and start excreting working fusion power plants out their back ends.

                      Or it’ll become even scarcer if we get serious about stopping fossil fuel use and stop extracting natural gas, of which helium is a by-product.

                      But as far as lift goes, the difference between a bouyancy of 1.12kg/m^3 for hydrogen and 1.03 kg/m^3 for helium disappears pretty quickly when you need much more robust containment for the hydrogen.

                    • Stuart Munro …
                      12 July 2018 at 7:18 pm

                      I think perhaps we should forego the alien unicorns for the moment. It is sufficient to use a contemporary equivalent of goldbeater skins for hydrogen and design for some loss. That’s part of the reason for using unmanned craft.

                      The logical trial is probably Cook Strait – the winds are more than ideal but there’s enough cargo and a decent hangar site somewhere near Blenheim.

                  12 July 2018 at 6:22 pm

                  I had a wonderful idea that if you contained the hydrogen in an aerogel matrix and then contain that in a lift bag in a dirigible, the resistance from the matrix would make the hydrogen burn controllably/extinguishably rather than catastrophically.

                  Googling informed me that this had already been considered, reduced the lifting differential by about 99% so was impractical, and was literally a thought exercise for first-year engineering students at some universities. Sigh. Just goes to show the value of formal education over googling.

                  But I still think there are some materials thresholds that some company or NASA have in a file somewhere, so when we get the right material (with a value of some function of a cost of W, a density of Y , and a temperature tolerance of >Z) suddenly cost-effective hydrogen lift bags would have lots of little cells that can contain the burning hydrogen from a leak without popping like a balloon (introducing more air/hydrogen contact so “boom”) or destroying the neighbouring cells (i.e. burning the entire vessel like the Hindenberg) and dirigibles will be the next big thing.

                  And logging trucks a thing of the past.

                    12 July 2018 at 6:49 pm

                    To get bouyancy, the total combined density of your lifting substance and containment has to be less then the density of air, which is around 1.2 kg/m^3.

                    Now consider, what is air? Air is a bunch of fairly low-mass molecules flying around and bouncing off each other, with no kind of structure whatsoever. The molecules are flying so fast and bouncing off each other so hard their average distance apart is actually very large. As soon as any kind of structure is imposed, then the intermolecular distances become much closer (and density goes way up). So even if that structure is almost entirely empty space, it’s still denser than a gas. The lowest density aerogel produced was 1.0 kg/m3, after the air is evacuated out of it, so if it were evacuated it would only have a bouyancy of 0.2 kg/m3 in air.

                    So really the only practical possibility to get bouyancy is replacing the air inside a very light container with another gas, but of lower density. Nitrogen has a molecular weight of 28, oxygen is 32. So the candidates are neon (20), helium (4) and hydrogen (2). Lithium, beryllium, boron and carbon are solids and fluorine is heavier than air. So using either hydrogen or helium can get you bouyancy over 1 kg/m^3 in air (which also has to lift whatever is containing your hydrogen or helium)

                    • McFlock …
                      12 July 2018 at 7:07 pm

                      Yeah. Seemed like a good idea at the pub though, lol.
                      Then I did the math.

                      And those bouyancy numbers are for sea level at a temperate temperature, too.

                      But the main danger with hydrogen is a cascading conflagration of large volumes of it. So if you can either limit the spread from one smaller cell to another or stop the fire from spreading along the gas cell, then hydrogen lift might be safer.

                      Essentially, I’m talking hazard minimisation and Stuart’s automation idea is hazard isolation (keeping people away from thing that goes boom). Helium is hazard elimination, but has its own costs and inefficiencies.

                      The materials side of it shouldn’t be underestimated. Hydrogen permeating through materials and changing their properties really is a problem, particularly if you’re expecting a long lifetime from your item.

                12 July 2018 at 6:05 pm

                Yep. 20-odd years ago my boss, VP of Sales and Engineering (that’s an, ahem, interesting, combo of responsibilities) got wind of how much people were willing to pay for carbon composite tanks for hydrogen. So I got the job of scoping out what would need to happen for the company to be able to make them.

                He wasn’t much for listening to reason, but the list of materials technologies we would have to learn about and develop, the testing and detection equipment we’d need, and the hazards involved with handling hydrogen quickly set him off looking for a different next big thing.

    “Carbon budgeting is a proposed part of the Government’s Zero Carbon Bill, which aspires to drive emissions of CO2”

    Progressives in the US are starting to get very popular.
    Alexandria Ocasio-Cortez, for instance, won an election she wasn’t even running for in a neighboring district due to write-in votes. She can not run in two districts however so had to turn it down. A lot of these people are wining by word of mouth due to the MSM refusing to give them any coverage.
    The tide is slowly turning against Trump and the Republican in the US. It is even turning against the Corporate Democrats that are in a lot of cases just Republican Lite candidates and they are slowly losing a lot of primaries to true progressive candidates who are then in a lot of cases going on to win their seats.
    Hopefully, a majority of these socially conscious candidates can get elected there and help turn the US around. We here in New Zealand will feel the effects of the world imploding if the Republicans continue their warmongering and polluting of the globe.
    What little work Obama did in the way conservation and climate change reform has been slowly unraveled by Trump and his cronies.

    Israel tightens noose around Gaza another notch
    July 11, 2018

    As mass Palestinian protests enter their fourth month, Israel is intensifying its already-crippling blockade of the Gaza Strip. Prime Minister Benjamin Netanyahu says Israel will close Kerem Shalom, the only crossing for commercial goods into Gaza. This will ban all imports and exports on top of the sweeping besiegement already in place. Israel is also reducing the fishing zone for Gazans off the Mediterranean coast to just six miles out, down from nine. More actions are said to be coming. This comes as Israeli forces continue to open fire on Palestinians taking part in the Great March of Return. The Gaza Health Ministry says that overall, 136 Palestinians have been killed, and more than 15600 injured. Israeli forces killed at least one Palestinian and wounded nearly 400 on Friday. The blockade and casualties have overwhelmed Gaza’s crippled healthcare system, which the UN warns is already at a breaking point. ….

    Loyd that’s the way no need to brand all of the people for one idiot’s bad behavior in Britain .
    As for trump Mark well you think its OK for trump to fly around Papatunuku and demanded that the rest of the United Nations members double the money they spend on the IDIOT war machine when they know that they might as well just dig a big hole and pour the money in it . We have billions of people in Africa and the Middle East and right on his door step North America all around Papatuanuku who need the west help just to get a drink of water . It would be OK if trump was demanding for more money to help these people and don’t believe any stats coming out of America about trump those will be manipulated by him to make him look good enough said .

    Fonterra should have brought Nestle all those years ago now they would be the biggest food company on the Papatuanuku .
    Yes Tamiti there are good polytechnic in Rotorua but they need to connect the trainees to the jobs after there training finished thats what is needed .
    Duncan so you think that trump locking thousands of mokopunas in cages on the United states boarder’s.??????????????? is not moko abuse. The reason there is so much bad stats on mokos is the Governments have caused this by starving te tangata whenua of money of jobs and mana using the media to smear maoris mana Mean while the wealthy tangata whenua are in total denial that there is a big problem with this system towards Maori so long as there hip pocktes are full they put there heads in Papatuanuku any culture that’s suppressed and divided will produce bad stats and whose pushing the Pee.
