i dont suppose it occurs to you that you are a bit biased and ill-informed. copy and paste dosent mean thruth. if you look thru google you will always find something that backs your view no matter the truth

Electric Aeroplanes will be SLOW. Theres no such thing as an Electric Turboprop, (Avg Turboprop speed around 450-500 Kmh), and no such thing as an electric Turbofan Jet, (Avg Turbofan speed around 750-900Kmh). Any plane with an electrically driven propeller is unlikely to attain even close to the TurboProp speeds.
Enjoy your trip to Australia at 250Kmh. Hmm lets see 6-7 hours to the Gold Coast - If you can find a plane which has the battery capacity to do that ?

very very slow and very very heavy. with huge battery storage area and very small seating and a very small millage range so aussie probably out of range for now. maybe in 10 years or so with massive advancement

I don't see a move to EV's as being particularly bad news for mechanics, the motor is they only difference. Why should EV's motors be any more reliable than the alternators and starter motors of ICE cars? They rest of the vehicle is very similar, brakes (OK , I do know about regenerative braking - there will still be an ABS and hydraulic system), lights, steering racks, wheels and suspension etc, etc. And we all know the most problematic system of a modern car is In fact the electrics. When did a mechanic last do a full engine overhaul of an IC motor? The mechanics will be fine.

That "drivel"?
You believe it is in the design 'faze'? (It's 'phase')
If only there was some way of finding out. Like Google maybe?
In short, 3 of the 5 bits needed are already completed and "we are now targeting completion by May 2022"
Under a year to they are done and it will allow up to a GW to flow North.
Still under planning is other improvements like pumped storage; personally I think a billion dropped into PV could be a bigger win for the North island

No exhaust/cat, no MAF/O2/timing sensors, no thermostats, only a dinky low-temperature radiator, no spark plugs or coils, no timing belts or chains, no oil changes or leaks, no CVTs or indeed any transmission to speak of, no putting diesel in the petrol tank, etc. etc.
Seems to me these are all bread and butter repair jobs that will eventually go away. Sure body electrics will still be a problem but the drive system electrics not so much, EV motors (apart from the earlier Tesla ones) are way tougher than alternators.

Yeah, but mechanics are pretty smart, they can easily retrain in another trade.
Once you have one trade, it is pretty easy to learn another.

There is no real reason why an electrical plane should be slower than a turboprop. It just comes down to engine power. The smaller turboprop aircraft don't have terribly powerful engines.
Of course the payload will have to be reduced a bit due to the lower energy density of the batteries, but the electricity is cheaper than the fuel.
I don't think that they were planned for long range flights at this stage, like to Australia, just domestic short hops.
There was a BBC article I heard a couple of years ago on the future of carbon neutral aviation. It had an interesting statistic on it:
Aviation only is responsible for 5% of the world's carbon emissions. "Hmmm, that's not so bad" I thought, listening to the article on the radio as I was working on the night shift in the aircraft engine overhaul shop, disassembling an aircraft engine fan.
Then the next statistic: "Only 5% of the world's population fly" "OK, that's quite bad!" I thought.
So it is a bit of a problem, especially as the aircraft are flying at high altitudes and it has more of an effect, I understand.
Maybe we need more airships? Might be cheaper on fuel as don't have to use the energy to provide the lift? Shouldn't has the same problems with fires as in the past as we have better materials since the '30s and shouldn't get so much hydrogen leaking.

"The smaller turboprop aircraft don't have terribly powerful engines."
Correct me if I'm wrong but the 19 seater Beech 1900 Engines are rated at 1100 shaft HP. The plane had two of them how can you get that much power from battery run electric engines.

very funny. difference between a mechanic and electrician is so vast no mechanic unless very young would ever bother with retraining. maybe they could take up working a tow truck to rescue all the evs stuck on broken down on side of road

Yep. I'm a chippy now, hopefully won't take too long to retrain in Neurosurgery.

Funny, because at the Engine Shop (doing aircraft gas turbines) there were plenty of motor mechanics who had retrained in aircraft engineering.

1100 hp should be pretty achievable for a modern 3 phase electric motor.

yes looks very easy to qualify as an aicraft turbine engineer below is details. i can just see all the mechanics doing this. only trouble what do the live on during years of training
and apart from that a mechanic job is definatly similar

Those links are for in Canada. Here you work under supervision and you can work on your unit standards at the same time. You are getting paid at all times. Once you've achieved your unit standards, NZQA will issue your trade certificate.

i admit im not sure how they train. however there are very few aof this type of job in nz compared to mechanics. i used to work for NAC and was there at changeover to air nz and at that stage in wellington they had a huge hanger backing onto golf course and there were around 20 people who worked there and that included refuellers and other small jobs and some work on engines. any way that stopped and which was pulled down and i think all work mopved to auckland. anyway thats hardly going to help the 1000s of mechanics that could loose there jobs. it wont happen though without huge advances in technology.
Your posts of ancient history are right up there with the modern fiction ones.

ancient history is always interesting and back then they had battery driven lights called torches. long metal tubes with light bulbs on ends and screw off ends which emityted out light when turned on but then advaced to plug in recharble ones but didnt take on. just to much bother. even your modern fiction postings can be interesting or at least a laugh on a cold winter day while waiting for car to charge

that is called upskilling or self improvment in my world. i used to rebuild race engines and the company that i worked for has branched out into aircraft piston engines. the last time i was there some of the guys reconded it was a downgrade.
Lets say our 19 seat plane needs two hours flying time, at an average of 75% power. We will day 1000Kw input to each engine. So 3000KwH total battery capacity for a total wight of 3 ton, this realistically would be needed for a 45 min max flight route. Our Beech normally can carry 2 ton fuel for a service range of 1.5 hours flying. The extra ton would come out of normal load capacity of just under 3 tons to load reduced by 1/3 for the 30 minute flight. And on such a flight the turbine powered plane would carry way lass fuel than max.
I have a sneaking suspicion that the cost of electrical energy for the flight is not going to be much less than the cost of ATK for the same flight. And the plane can do a 30 minute turn around including fueling.

stick it, most of us won't change and don't want to change and will only change if we want to, ardern can stick her BS green crap where the sun don't shine and won't be in power much longer, she is screwing over everyone , including the poor and the hard working, wait till the buy back starts on ute accessories, like the gun buy back with deflated values, good luck with your hobbies, lifestyles and jobs, you could retrain as a communist storm trooper - informer. that a opening coming soon during this term.
