That seems like a brilliant idea to me, what could possibly go wrong? Maybe losing the wifi link when the power completely fails?

wind might've been a better option in this case....oh wait that's already been done :D
Auckland will need to get used to this when they get their electric ferries that won't even be able to do a return trip to Waiheke Island.
They should be made to install a Diesel engine in parallel through a transmission. Imagine if it happened on an outgoing tide with some northerly weather. Nek minit Barrett Reef. "Yeah, we drowned some peeps but hey, zero emissions so all good..."
Looking forward to electric aircraft. Luckily i don't live under any airline flight path.
nuclear ships seem to go alright.... but nz is a bit too green for that i guess.
Diesel electric........the sheeple would only hear the ecectric bit! And way more reliable
Dumb as a plank idea springs to mind. Fuck, some people just aren't worth saving.
Its in a similar vein to the electric fire truck that is now working...ooops, that should be charging in Los Angeles. Has got an insanely short duration (30km max to a fire, and can only carry 60% water, and was 2.5 times the price of a diesel one. FFS, I think the emissions from the burning house will be a tad more worrying than a diesel fire engine running a tier 5 diesel donk.
this new Extended Range Tesla springs to mind
Attachment 206986
Let's ignore the electric vs emissions for a moment.... and come back to me when it will handle 60+ knots and 5+m swells
The big one there is generally the boat will handle it if loaded and driven correctly but the generall populace as passengers not so much.Quote:

Nope. Good ol Lithium ion. Can only do the one return trip (25km) before requiring a recharge at...wait for it....1 megawatt charging rate:o
And received a 300,000 grant from the govt
The price will have been eye watering, given the high tech hull is all carbon fibre.

Ideally, cars, boats, trucks, etc should be run with electric motors, powered by hydrogen fuel cells.
Instead of bleeding off, or shutting down generation of electricity, when there's too much of it, electrolysis could be making hydrogen all the time, 24 hrs a day, from existing electricity generation. See Tiwai Point.
Given that the taxpayer already paid, for all the Hydro in NZ, the electricity should be almost free, apart from maintenance costs (that's before it was flogged off for pennies, to private money men). Remove the profit quotient from NZ's electricity industry, and we're set.
If you want a proof of concept, see Team NZ's new chase boat.
I'll buy an EV when they can do 1000km to a charge since that is the range of my current vehicle on a tank of diesel. As for EV boats and planes they are coming but so far ideas outweigh practicality.
Yeah, for a work vehicle in a remote-site contracting outfit an EV will never do it. Ever. Cost too much, and the battery would need to be so big that the vehicle couldn't carry the required cargo...
All you naysayers are doing is demonstrating your lack of knowledge. Heaps of electric prime movers in underground mining (and have been for a century at least), many yachts have electric main engines and have done for at least 30 years . . . Electric is the way "back to the future" - we just have to learn hiw to do it. Must put fhe Stihl electric saw battery on charge, hell of a productivity tool, I estimate it saves me at least two hours a week, reduces and simplifies my tool bin and is safer to boot.
Electric is NOT the issue. Fastest Tuna Purse Seiner I ever worked on was Diesel / Electric. With all the geni's online the thin did 29kts which was not too bad for 109m vessel.
The thing was an absolute beast!!
Its when you are using rechargeable batteries as your "generators" that the problems start. You have to charge them somehow and there's no plan b if it all turns to pooze.
Imagine the new NZ 1 flight was electric / battery powered.........................."ladies and gentlemen this is your captain speaking, as a result of unexpected headwinds we have used almost all our battery reserves and will be landing rather unexpectedly and in a hurry"
Have you not had a read about air nz's direct flight from New York...Quote:

Here we go, comparing apples with effluent. Electric prime movers in a mine site are powered by what? Yep diesel. Electric motors powering ships - yep diesel. We had electric powered ships in WWII, yep they cocked up and blew up with relentless monotony. There are advantages to electric, namely for ships the shorter driveline allows for flatter shaft angles which is more hydraulically efficient. But, they fail more often due to the magic smoke getting toey and deciding to piss off...Quote:

Maybe they need an electric cable ferry.
The cable ferry idea having already been taken:-)
havent they got a set of jumper leads on board and the number of AA roadside assist.???????
that would mean the auto association would be carrying AA batteries :thumbsup:Quote:

Mind you i dont like electronic dive computors either. Water and electrics dont mix.

ok so lets tal khand drillsQuote:

then there is about 4 plug in electric drills...VERY fast bit speed and torque
I dont have a internal combustion hand drill but have used petrol post hole borers in the past,guess thats nearest comparison....or maybe its when I crank up the jenny and plug drill into it.
which really is close to what is described..small petrol diesel mottor making electricity to drive an effecient electric motor to do the work...
submarines were diesel electric,pretty sure some still are. using the strong points of both types of power is the key to the future.
relying solely on electric is just as short sighted and doomed to failure as soley relying on fossil fuel...or wind or solar or man power or horse shit methane.... eggs in one basket comes to mind.
Micky, Micky, Micky, logic has no place when it comes to virtue signalling about climate change.
The fact that you are 100% right is outweighed by the kudos gained by ‘saving’ the planet. :thumbsup:
I recall my first experience with a 36v cordless drill. I had no idea what the actual difference was between 36v and 18v, I needed a hole through a bit of timber framing holding up a roof so I grabbed the available drill and up the ladder I went. Lined this puppy up, hauled back on the trigger with the ignorance of the uniformed and proceeded to just about get inverted when the drill bit grabbed on a knot. By inverted, I mean me feet just about pointed at the sky, I was well clear of the ladder it was comic book level stuff!
That drill was awesome - for about 4 or 5 holes... It sucked the battery into a coke bottle shape faster than anything I've used before or after and that in a nutshell is the main issue with grunty cordless tools. You can carry a supply of petrol much easier than a supply of batteries, and the tools generally have more grunt plus they come with that factor that you know how much grunt they have so you don't do dumb sh1t like I did!
Gentlemen, the following is a bit of a tangent, but it's related to the Electric - Emission debate:
I understand that the basic tenet, behind addressing global climate change, is that we want to get a country's emissions back to where they were before...
A mere thousand-ish years ago, or thereabouts, New Zealand had no people, none.
There were numerous Moa, across the land. Moa, now extinct, were like Ostriches, Emu, Rhea and Cassowary.
Question: do Ostriches, Emu, Rea and Cassowary fart?
If so at what rate? and if we were to apply that rate to the population of Moa that were extant pre human, how would that figure in the climate change debate?
If we want to get emissions back to the levels, they were before, surely we can offset the Moa's emissions, which were there, since forever, against the emissions of Cows and Sheep these days?
Ahhhhh but grasshopper, this does not suit the agenda. You can't make sweeping changes to a country that gets you huge international notoriety by being practical! We have huge numbers of wildling pines - I bet those buggers suck up some carbon too but because they are feral and not assigned to a favourite (read compliant) personage we can't acknowledge them! Also like individuals just getting hammered to change behaviours by cost - no thought to incentivising behaviour change in a positive way (and I class EV's in the nuetral bracket so far - they just shift the carbon from here to somewhere else).Quote:
