Also the maritime speed limits in both harbours would mean 35 minutes would be spent in the harbours alone, that's assuming the whole crazy idea of a seaglider actually worked.

Not quibbling your general conclusion, but the Whangarei end of the trip is right next to the open ocean, not up the harbour.

My big huh‽ moment is why it would be going from Marsden Cove (basically Marsden Point) instead of up the long Whangarei Harbour - it takes easily 30 minutes to drive there from Whangarei - 1/4 of the entire drive to Auckland. It is comparable to having a service to Auckland that terminates in Whangaparoa or Torbay.

Oops, overlooked the Marsden Cove bit.

Your point about the time to drive there makes up for it. Also I suspect the time at slow speed in the Auckland area will be more the half if 35 minutes

There's crazy then there's crazy. This one defies the laws of physics.

For this to have a remote chance of success it needs technology which doesn't exist and isn't even on the horizon.

It ain't going to happen. If you want to flush away your money on such a venture that's up to you, just dont use any of my money via taxes on such an idea.

A quote without attribution is meaningless. It could have been said by your grandmother.

Look up “Otto Lilienthal” if you want to learn a bit more about the beginnings of heavier than air flight.

“Of all the men who attacked the flying problem in the 19th century, Otto Lilienthal was easily the most important. ... It is true that attempts at gliding had been made hundreds of years before him, and that in the nineteenth century, Cayley, Spencer, Wenham, Mouillard, and many others were reported to have made feeble attempts to glide, but their failures were so complete that nothing of value resulted.”

— Wilbur Wright

True, however this concept combines two impractical/physically impossible ideas with an impossibily short time frame. It can't happen.

Battery electric aircraft of this size cannot work with current technology. Tecnam have just announced they have stopped work on their battery aircraft. No doubt one day we will see battery technology improve to where it needs to be for it to be used in this size of aircraft but that day is a long way off, certainly not before 2026.

WIGE (Wing In Ground Effect) is a known concept and has been around for a long time. However It has also proven to be impractical for general use. They only application has been in an inland sea and that operation is no longer in use.

I get the impression the proponents of this idea seem to think making the WIGE vehicle electric somehow makes WIGE work. It dosen't. With current battery tech the reverse is true.

As I've said before electrification is not an enabler in fact it is a disabler in this instance. If these seagliders actually worked they'd already be in use with ICE powerplants

and the airfish does use ICE engines. in the video footage you can clearly see why they used it on icy flat sea. airfish series is getting old now, you would have thought it would have advanced more if it was viable.

But surely it must be going to work. The recent Stuff article says so:

“The seagliders are expected to reach speeds of up to … 540kph for larger craft that can seat 100 people …”.

😀

Just to recap, Ocean Flyer NZ’s $700m deal is for 15 Viceroys, which can hold up to 12 passengers each, along with 10 Monarchs, which can hold up to 100 passengers each. The Viceroys are planned to be used on routes up to 300km and travel at nearly 300km/h, while the Monarchs can travel at nearly 540km/h and are planned for routes up to 800km.

Sometimes I just sit and think. Other times I just sit.

I can't find any evidence of the Airfish being used anywhere, especially not in a commercial sense. All I can find are proof of concept videos. Based on what I can find they're not really in use at all.

exactly my point.

i think there is only two airfish8's and one thats flying which you can see in one of the promo video's. not sure on the early ones.

Sorry, I missed your point initially. I wasn't aware of the Airfish and thought you were referring to it being in service. My mistake.

thats ok. notice in the video's the lack of waves.

all flying boats have a landing speed and a landing wave height. you can't just land if something goes wrong. if you clip the water at high speeds, its all over.

There may be a particular application under particular conditions, but it seems this company has gone for gold in claims.
I really do hope the regions queueing up to get publicity to be part of this revolution are not throwing ratepayer money at them.

Noting that claiming revolutionary performance is easy until you have to deliver.

An electric Big Rig company that displayed what it claimed was a 'revolutionary' fully working product.
It was just a static mock up, plus all sorts of other claims to pump up investment.

A biomedical company that claimed to have working revolutionary almost 'magical' testing equipment.
It propelled the CEO to one of the richest women in the world, a TED talk star !
https://edition.cnn.com/2022/07/07/tech/theranos-rise-and-fall/index.html

Another company that was propelled on a wave of I can do better than above 'magic' fiction.

""
Arrayit compared itself to Theranos, the failed blood-testing start-up, at least once in its Facebook page, writing that its technology can use drops of blood “which are 250,000 times smaller than the volume of the Theranos nanotainer,”
""

We also had our own NZ superfund years ago investing into small shrouded wind turbines that defied physics.
It didn't, and $150M disappeared.
About 20min into this EEVblog reviews this.( 22.27) NZ get its mention about losing $50M ( 23.45) !.

The difference between an Otto Lilienthal, a Wilbur Wright and other aviation geniuses has always been that they did not, as they do today, noisily pitch their vague ideas and visions to people in advance in colourful marketing brochures before they had flown the technical data themselves, in some cases painfully. Today, only ingenious, visionary, well-managed teams can come up with complex, technical solutions, but certainly not their colleagues from the marketing department.
