  1. yeah couldn't agree more, they were forced into it rather than it being a natural progression. I guess it all comes done to pure numbers or quantities,I think killing cylinders would be easier and probably a better outcome, not sure why bmw havn't done that my 7 km drive to work has one stop sign and one set of lights,if its stops its for less than 45 seconds ever unless a train happens to come through town as its scheduled to do at 5.15pm every night but I guess in Auckland it all adds up, it can be coded to remember the last settings at turn off with software too
  2. sales guy told us it learns your route and then overrides it at certain stop signs etc, it certainly appears to know every morning where you are going just like your phone so I guess its not beyond the realms. we have noticed it not working lately on very familiar streets and even when we pull up to open our gates to property but kicks in if your going somewhere different, its not great in an f40 there's a definite shake or vibration as the 3 cyl fires up which gets tiring really fast, the fours seem much better and in the big ones you'd struggle to hear it had even stopped. wish they gave you the choice or it remembering your on/off state and not resetting everytime you start the car though an f40 at idle is not exactly thirsty
  3. That is a stunningly dismissive statement of what appears to be a genuine effort to document the effects of stop-start operation on various engine operating parameters. Quite frankly it sounds like something a Chinaphobe would say, but sobeit pot kettle you were obviously interested enough to comment first you gave us your expert opinion, completely write off the video with smarmy comments that because he didnt do the tests,( its invalid etc you rave on for a whole paragraph with a personal theory about starters and whether they allowed for that, FFS just watch it and save yourself the embarrassment next time all without, by your omission, watching it you make a weak joke about all of youtube being crap, then trying to defend your obvious smuggness in the first post actually find and give a counter arguement, (good thats how its supposed to be done) yes the video was dummed down to make it watchable in todays 15sec attention span audience and it was done with humour. unlike yours where 90% would just say TLDR then when someone dismisses your argument mostly in jest but just probably trying to point out to you your smugness , like a typical lefty you make it personal, start calling someone names, Chinaphobe (FFS how embarrasing for you and you should apologise) make it personal because thats how any lefty wins an arguement, hint that the person is RACIST and bang I win. I don't know why I'm even writing this because I know it all just flying past your head, God help my grandkids with the state of NZers critical thinking now Trying to discuss anything with a lefty is like banging your head against a wall, unopen to anything that might contradict your preconformed science if it doesn't come from the podium of truth, the single source, it must be burned to the ground.
  4. Ive always believed stop start was a waste of time , may have to reconsider now, its interesting that i think most people quietly agreed but I guess manufacturers would hardly have bothered with all the expense if they didn't know something we didn't
  5. wow, just wow I can see why they want to give the vote to 16 yr olds now you must be hanging out for booster #4 by now
  6. cut and pasted, has some interesting figures on NZ current power generation and usage The investigation report on Lake Onslow is supposed to be released soon. This will be touted by the incompetent Minister as a real game changer but needs more taxpayer money to be wasted. Yet they won’t release the economic analysis to justify it. In any sensible world, this would be the first thing done. But in the Kiwibuild era, that type of report would just be decried as naysaying and the old paradigm. So for benefit of Kiwiblog readers, if you indulge me, here is the condensed version. Remember it when the Minister’s PR comes out about how good Onslow is and the puff pieces about it being a real game changer. I haven’t included links as it would make this post too long. However, the info is factual so easily checked with public domain data – look for numbers and units, not words. A good place to start is here: https://www.transpower.co.nz/system-operator Read their reports. Electrical energy is in Watt hours, Power is Watts – they measure different things, though many ignorant commentators confuse them, Nomenclature and units are a good way of quickly sorting the parrots out to disregard their twitterings. And remember, get units correct; kilo(k), mega(M), giga (G) and Tera(T). NZ uses about 45TWh of electricity a year ~125GWh a day; more in winter, less in summer. It needs to generate significantly more than this to allow for losses (heat) on overloaded equipment. However, during a day, the power varies greatly. It is about 3GW at 4am and the peak about 6.5GW. Usually, absolute peak is about 6pm but the demand is high 7am to 9am and 5pm to 8pm. The generation has to match the demand within 1% at all times. If it doesn’t, then demand response is needed (a euphemism for turning your power off). Biggest single unit on the grid is about 400MW (a gas burner) at full load. Most are less than 100MW – lots of littleuns. For operational and maintenance reasons, hydro units don’t like being at part load. Most are either flat out or off. An average 21TWh p.a. is generated by hydro, but this can vary from 16-24TWh depending on rainfall in hydro catchments. Typical thermal generation is around 10TWh a year, but half this is the make up for hydro/ wind shortfalls on a day to day basis. Onslow is supposed to replace a lot of this thermal – nominal 5TWh in dry years. It was going to store the mythical hydro spill (where water goes down the spillway, rather than through unused units) This last happened in 12 years ago when we had a lot more gas burning power stations. There is no surplus to spill there now. Solar and wind are really good at generating power when it isn’t needed. We can hold back some water, running hydros less when the unreliables are generating, but that ability is very close to already being maxed out. That means the shortfall has to be covered by ramping up and down thermals – in $/MWh terms, about 10% of the cost of getting the electricity from batteries. The typical electricity price on the spot market over the course of the year is around $150/ MWh. This is 15c a unit (kWh) of your power bill, rest is distribution and administration charges, plus the increasing costs of bad debts. Winter, it is higher prices and summer lower. When the thermals are running, a major part of their costs are carbon charges. For Huntly, it is around 10c a unit. At that wholesale $150 price, many new power stations are still not economic to build and operate. Even just getting consents (they are front end charges ) is a significant cost on future power. The above sets the scene. If we take Onslow sells a full lake of power at $200/MWh once every 5 years, that is an income of $1B. The other 4 years they have to buy power off the grid to fill the lake. They need to buy 20% more to allow for losses and inefficiencies. So that is an average 1.5TWh a year. If this is bought at say $100/MWh, then that is an expenditure over the 5 year cycle of $600M. So gross income averaged over that cycle is $80M a year. Then one has to subtract finance, administration and operating costs of say $20M. So there would be a net income of $60M a year. That “profit” has to pay for the cost of construction. For a long life asset for this, the nominal capital payback should be maybe 20 years. So anything more than $1.2B to build is losing money. And note all my assumptions were on the optimistic side for the government analysis. Nor have I added interest. Now look up the cost quoted for Onslow and remember hydros usually cost twice as much as original budget price. The consents, which will be opposed, will add big delays and increase the costs further. I haven’t even factored in all the transmission upgrades needed which would more than double the overall costs. To get the “cheap” wet year power, they will have to buy off a surplus generated by power stations yet to be built. There isn’t any there from existing stations unless we burn more coal. However, at that cheap buying price, the companies won’t build new stations as they would lose money. So building Onslow would guarantee no new stations would be built unless the power price to consumer went up by maybe 20c a unit in real terms. Think what this will do to cost of living, inflation and the economy. That simple economic analysis above is why the generation companies are not interested in it at all. They can do the sums – it is a massive white elephant that will drag their balance sheets negative. Though the Labour appointees on the company boards might force bad commercial decisions – it has happened before. The only current support for it is from sycophants to give a vanity project to a Minister who wants to be seen to be doing something but is out of her depth in a puddle. If they were to do day to day energy trading, like Dinorwig does, Onslow could replace thermal and cover the unreliability of overbuilt wind and solar. The lake could be smaller, but the power station would need to be bigger. Basic economics are better, though not positive, but still no new stations would be built and there would be no dry year reserve.

  8. I don't deny EVs are here to stay, rightly or wrongly its going to happen, we all seem to agree that NZ will do it badly without thinking the whole thing through generation wise etc but it will still happen. Considering we are sitting on gigantic oil reserves and could have been the next Oman, UAE it does make you cringe a bit but .we've gone from one of the highest standards of living in the world in the 60s to this so I guess it's inevitable.Just wish people would wake up and question a few things, have some critical thoughts for a change instead of just following Hillary Barry. its not about saving the planet they don't give a toss about that, oil companies are the major shareholders in the renewables, they have just realised its a way to scrap everything and sell you all something ne w. just follow the money, its always about the money when you realise it always ends up at the same 2 companies you see we are just hamsters on a wheel
  9. because overseas its been tried and it doesn't stand up to scrutiny, old plant litters deserts everywhere, kills wildlife like crazy and is hard to dispose of. costs to install aren't recovered There isn't a serious scientist worldwide including the founder of greenpeace that now doesn't agree that nuclear is the cleanest safest fuel generation, not cherynobl size just little nuclear sub sized easily moved to where they need to be, easily covered if something goes wrong but the tech of nuclear has come along way anyway subs are all have reasonable safety records so far , we just need to convince the public but in the end it will happen watch europe recommission nuclear big time now that they are bent over by Putin and have finally realised
  10. heres a study done by tesla itself on total cost of ownership,fuel prices have risen since the war but so has electricity in most countries https://www.msn.com/en-nz/lifestyle/shopping/tesla-model-3-rwd-5-year-cost-of-ownership-versus-toyota-camry/ar-AAXlNl9?ocid=msedgntp&cvid=1143af5eb9614155823b060221cf3161
  11. like I alluded to above, those home panels actually add costs to the generators and their business models go out the window, they build a power station to provide power 24/7 not just to cover the times your panels arn't working. we will need more generation to cope anybody can see that, no dams allowed, no gas, wind requires 80-100 % backup so you need another system of equal size to cope with slow days,solar similar, more coal , oh and shipped on a evil diesil ship hmmm your getting away with it currently but it all falls over once you reach a critical mass a bit like not paying ruc, good on you for being ahead of the curve but its not going to end well UK power bills have doubled in last 12 months with power estimated at anything from 10-25% of entire household income AUS power costs have doubled in SA , Queensland in last 12 months and expected to keep going higher this is a greenie costs tho, not blaming EVS for that Europe, US and others are all asking people to not charge cars and cut power use due to oversubscription and wind/solar not performing as promised alot of insurance companies are getting very jumpy about EVs charging and house fires every day there's another video of some electric bus igniting into a fireball usually parked at the time and boy there spectacular and this is now becoming a problem? https://www.stuff.co.nz/business/128270062/shipping-giant-mol-confirms-it-has-stopped-carrying-used-evs-over-safety-concern
  12. judging buy how much indonesian coal we are importing absolutely nil it would appear https://www.rnz.co.nz/news/national/447679/new-zealand-likely-to-have-record-high-imports-of-coal-in-2021-officials
  13. its very complicated but the cook cables are old and not designed to take tiwai capacity, yes power is obviously transported from south to north but it doesn't get all the way to the top,too much loss etc and its not like you can suddenly double it. Im not denying EV are here to stay and going to be huge but even california is turning off and asking people to not charge their vehicles due to overloading smart charger , yes they have a timer but you are still asking every car owner to try to recharge from 5 till say 7am and most are 6 hours plus so there is tremendous overlap of times and to say that its cheap because its off peak rates. do you really think it will still be off peak when everyone has a EV and is charging overnight it will be max peak and charged as such,
  14. closing a smelting plant does nothing to power in Auckland, it can't be transferred from one end of country to the other. and flexibility is bollocks, 95% of evs will arrive home after 5pm to go on charge. Unless private companies like wilsons install them all through their multistory carparks then you got places like wellington where every govt worker lives with the car parked on the street down a cliff from the house, going to be a lot of extension leads the whole thing is a joke until they agree to build a nuclear sub sized reactor in a container and place it somewhere near auckland they are screwed. aus the country with the largest private solar panel input has now realised it screws the power companies up, they still need to have the generating capacity to cover nights and windless days etc but they also lose all the profits of being sole supplier . their business model doesn't work basically when you have people all giving power back to the grid at unneeded times, but you still need to cover them with generation capacity in case.
  15. and you probably would have found if you waited the battery would have recovered enough to start itself just, spent many frosty mornings turning over cars till just a clunk, wait 15mins and go back and theres enough to fire it if your quick and lucky there seems to be enough chemical reaction in a newish battery to kind of float the levels perhaps, not sure of the physics of the thing but it happens. unless you left the lights on and really killed it, no way back from that on batteries can't say how totaly impressive these are https://www.repco.co.nz/en/globes-batteries-electrical/battery-chargers-power-accessories/car-battery-chargers/ctek-battery-charger-12v-5amp-mxs5-0/p/A1247337?kwSearch=intelligent charger wifes f40 2021 model got a software update that downloaded from her phone to the idrive but never got to a postion to autoinstall. google said its always a battery charge thing , you needed to go on a long drive first etc etc so after spending the night on a plain 12v charger there was no difference. about to give up but everyone raves about these ctek so bought one on a good sale. 24hr later to do the full cycle and bang update went straight through. more than impressed, going to do a few other older cars on a restoration cycle now to see what happens but obviously battery tech has moved on from the old cheap chargers of old.
  16. its higher than petrol in Brisbane,considerably but I don't think they have RUC
  17. all the cheap ones I found on ebay were not NZ compatible frequency wise for our garage the trick is to buy the mirror with the buttons, and then dismantle your old garage remote down to its circuit board only , which can then be hidden somewhere inside the roof lining and run a hidden pr of wires from the button on the remote to the button on the mirror. basically you are just using the mirror button to temporarily short a circuit and its very easy to do. its easy to see the points on the circuit board that the existing switch is actually working on and solder wires to them. you can buy really tiny replacement remotes for alot of merlin doors and you could possibly hide the whole circuit inside the mirror and bypass/cutout their incompatible circuit inside to make room for your hidden remote.
  18. I fitted one to an e39 years ago but it went in the headlining as opposed to being part of the mirror, you need to carefully check your frequencies though as garage remotes aren't the same world wide. the wiring was there already and there was no coding involved it was just a straight swop and worked like factory intended with our old 80s model merlin garage
  19. no apparently that's only related to the radio or the car going to sleep, lots of confused discussions on that on internet, its designed to stay on until all passengers have left as it detects everyone in the car, so they can listen to radio and have aircon while your filling up for example. that can get confused with child seats etc when you get home to your garage though and actually want it ti turn off. 3rd world problems I know
  20. Wife has a new toy, a 2020 F40 118i couple of annoying issues I can't figure out. Firstly the autostop/start is horrible, the car shudders when stopping and even worse when starting, guess that's an issue with 3 cyl as it sounds very tractor like when idling anyway. Goes extremely well when actually running so its not a tuning issue or anything.There is a manual button to disable autostop but it reverts at each journey to back on. I have ordered an enet cable but does anyone know if this is codeable for permanent disable. We don't live in a high traffic area and I would say the auto stop would save basically less than 1ltr of petrol per year. 2nd we back out the drive, stop and put car into park to shut the gates and the minute you open the door the engine turns off. same on the way home again and you actually have to push the start button to continue. Surely this can be overiden? have never seen any automatic car do this before and its crazy annoying.
  21. i did mine a few months ago, like you was sick of the cobwebs dust and leaves that accumulated all the time. I just lined in jib because of the cost. skyine garage the studs were 600 so that worked perfect with the sheets hung vertically so the joints were on studs and 2.4 just made the top plate i came up about 12 mm off the floor incase of puddles from a wet car but I also ran a pine skirting around floor because that 12mm gap was just a trap for leaves and crap that blow in and made sweeping so much easier. If it gets accidentally punctured its a 10 min job to replace a sheet. I also ran moulding around the window frames that finished them off because the jibs weak point is its edges. used a couple of pieces of 75 x 18 pine as mounting strips to hang all the gardening crap off at head height lined area above workbench in ply for a tool board it would have been better in ply or possibly mdf but I did it for $17 a sheet as opposed to $43 I think from memory but money was tight has made a world of difference and even unpainted its 300 % lighter in there, should have done it 10 yrs ago

    RIP Sabine

    she was obviously driving something pretty damn special though, she could out brake anybody anywhere and just blew past race cars like they wern't even trying, passed people around the outside of a corner, that was some special car in a totally different league, it was a video game style mismatch but made pretty good video for sure.

    for everybody else its a race, for her its just traffic https://www.youtube.com/watch?v=qnJOC_dDXzM
  24. I guess you have to have a point of difference tho I guess you have to have a point of difference, when joe bloggs kia has carplay you would expect something better from a premium brand wouldn't you. The costs must be horrific to do it and the threat of being hacked would be a smaller footprint than say generic android but wow your name would be mud if it came out that somebody could get into your cars software with some simple hack, they must live in constant dread of that happening
