  1. Moves are being made by a Kiwi rich-lister to see if the defence of the America's Cup can be held in Auckland after all.

    Mark Dunphy, CEO and chairman of Greymouth Petroleum and on New Zealand's rich list with an estimated worth of $230 million, is at the helm of the move to hold the 37th America's Cup in Auckland – most likely with a mix of private and Government funding.

    Dunphy has been speaking to the Royal New Zealand Yacht Squadron, the holders of the Cup, but says the squadron and Team New Zealand now need to answer the question: are they committed to a local defence if the money can be found?

    One insider spoken to by the Herald estimated that Dunphy and others are looking for up to $80m, maybe more, to bridge the gap between the (since withdrawn) Government offer of $99m and Team NZ's financial needs. Team NZ turned down that, though only about a third of that figure was in cash. Up to $200m has been mooted as the top end of a budget needed to finance a defence in the AC75 foiling monohulls.

     

    Another interesting aspect of the Dunphy America's Cup effort is that it is focusing largely on the RNZYS – although Dunphy said he had corresponded with Team NZ "through the squadron".

    One yachting source said: "If they find the money, it could lead to members of the current Team NZ migrating across to a new entity. There would seem to be two options – Team NZ either wind up or they could negotiate a defender series [where yachts from the defending country race off to decide who will sail in the Cup match]."

    He believed it could be from as long ago as the very early 1800s or even the 1700s.
    Willis and fellow expedition members Mark Willis and Dale Hedgcock unearthed the cannon late last month.

    They were at a Chalky Inlet beach when they spotted a small, deep orange patch among the stones.

    Willis said team members were now waiting for the Ministry of Culture and Heritage to get back to them about how to go about retrieving the cannon. It had been too heavy to lift into their helicopter when they found it.

  3. i seem to remember muldoon's "think big" motunui methanol plant took natural gas that could run a car 500?km

    and turned it into synthetic petrol that would run a car 200?km

    (rather than turn that science project into a factory it would have been better/cheaper to simply give nz'ers free cng/lpg conversions for their cars)

    Efficiency[edit]

    In 2013, the round-trip efficiency of power-to-gas-storage was well below 50%, with the hydrogen path being able to reach a maximum efficiency of ~ 43% and methane of ~ 39% by using combined-cycle powerplants.

    https://en.wikipedia.org/wiki/Power-to-gas

    the loss back then was supposed to be worthwhile because we already had cars that ran on petrol and a petrol network  

    ...

    seems to me tiwai risks taking electricity that would run a car 500km and turning it into hydrogen to run a car 200km

    and we don't yet have cars with fuel cells (far more complex than attaching a simple cng/lng conversion or a hydrogen network (vastly more complex and difficult to store than cng/lpg......hydrogen boiling point -253C)

    https://energy.nl/en/fact_sheet/liquefied-hydrogen-storage/

    it will be interesting to see how it all pans out

  4. heard a dunedin? scientist on the radio this morning saying the huge green-hydrogen plant at tiwai just isn't going to happen

    apparently the science experiment they would like to scale up would require A LOT of platinum

    not a metal in great supply... 

    Fast forward five years and gold now is more than double the price of platinum, even as platinum is considered to be 30 times rarer than gold, and more expensive to mine, Caruso said.

    might be time to swap my hoarded toilet rolls for platinum

  5. looks like it could well become the big hydro-battery they're looking for 

    1920px-Lake_Onslow,_Central_Otago.jpg

    In 2019, the Interim Climate Change Committee proposed that the lake be used for a pumped hydro-storage system to provide backup electricity generation in dry years. The project had first been proposed in 2005 by hydrologist Earl Bardsley of the University of Waikato.[1][2] In July 2020, Minister of Energy Megan Woods announced that the New Zealand government would fund a detailed feasibility study of the plan.[3] If progressed, the scheme would be the biggest infrastructure project in New Zealand since the 1980s, employ an estimated 3500 to 4500 people, and take four to five years to build and a further two years to fill.[4] One option could be 5 TWh of storage and a 1.2 GW power station, equivalent to half a year of full production.[5]

  6. when i was younger i wanted to fly

    all of the; swooping, climbing, banking, wind in the face freedom appealed

    but top gun never happened and cessnas + commercial aviation seemed very constrained 

    however motorcycling ended up being the best source of those vitamins 

    currently enjoying the back roads

  7. still no one knows what to do with the waste

    canada - In 2005, the NWMO decided to build a deep repository dedicated to store the spent nuclear fuel underground. The $24 billion price tag of this 500- to 1000-metre underground vault is to be paid by a trust fund backed by the nuclear production companies. The spent fuel bundles would be placed in steel baskets wrapped together 3 by 3 (324 fuel bundles total) in corrosion resistant copper to form containers designed to last at least a 100,000 years.

  8. we can learn from the cautious scandis

    https://en.wikipedia.org/wiki/Nuclear_power_in_Finland   5.5 million   30% nuc power

    https://en.wikipedia.org/wiki/Nuclear_power_in_Sweden   10.1 million,  40% nuc power

    denmark 5.8 million, no nuc power stations

    https://www.world-nuclear.org/information-library/country-profiles/countries-a-f/denmark.aspx

    norway 5.4 million,  no nuc power stations

  9. to fix busted microwave knobs i buy from jaycar with a solid brass insert and a grub screw

    if the white mark isn't in the right place, and it rarely is

    a bit of black and white paint makes them good
