Sorry Cudes, mate. That flight was not the first of any kind, except maybe for the NY area. That video is lying to you. You're entire problem in all of these discussion hinges on the fact that you seem the believe everything you see/hear/read, without BS testing what you are hearing. The Eviation Alice first flew* back in September 2022, when they had half a billion dollars in pre-orders from their debut at the Paris Air Show in 2019. They have not flown one single flight since, and have laid off most of their workforce. Look for more of the same here, with the plane in your video.Quote:

No battery operated airplane can do that on lithium ion. If the FAA is willing to lower their safety standards to accommodate battery operated airplanes, you might (maybe) see a battery operated short haul airplane actually in service.
Edit to add: Can you imagine flying in a blizzard in a battery operated airplane? We do it all the time in petro jets where there is so much extra heat from the compressor section, we use it to de-ice the wing leading edges in flight, and to anti-ice the engine cowlings in flight. I don't know if a battery airplane could manage to heat it's critical surfaces at minus 40 C, to keep ice off of them, and still stay in the air.
* They did have the dubious honour of having their plane burn to the ground in a lithium fire, before they ever flew it. LOL. Thankfully it was just sitting there in the hangar with nobody on board.

Gotta say the same as I have forever... You must have "point of use" power generation to switch power sources. This battery tech is a dead end. This is why we have never switched from ICE and maybe never will. Hydrogen has the best potential for any future electric vehicles IMO. Well, unless the aliens give us some tech we don't yet understand. hahahaa

Imagine that you come upon the scene, claiming to have unearthed a mysterious liquid that burns readily, can be pumped around at will, stores in a container of any shape, has unheard-of energy density, and to top it all off, effectively vanishes when its energy is extracted, so that it no longer needs to be lugged around. The claims would be so outlandish that you would be dismissed as a charlatan.

To further prove the point, my son just got a 2025 4x4 f 150. With a 5.0 coyote engine putting out 410 plus ponies using no power adders. The truck gets 23-24 mpg on reg fuel doing interstate runs at 80. 21 around town. That's fairly good for a truck and shows how far the efficency refinement has come. My 7.3 Ford gasser does 17-18 mpg on the interstate, while not good its pushing a 3/4 ton 4x4 truck along at 80 mph. Compared to my old 383 Z-28 this is great economy. It is in the 10 mpg range IF I stay off the loud pedal.
Displacement hulls are a much broader use-case for battery energy storage. Of course that says nothing about the payback period, where the ship has to operate until the it's high price is paid, before the owner is able to make a profit, and the bloke presenting the video says nothing about that, or whether it will be subsidized by the government of it's operator, (highly likely). Up until about 4:30, the presenter was just an ordinary, thin on facts, presenter. Then at 4:30 he tipped his hand when he went into a full-on lying exaggeration, when he said he would be out surfing and a conventionally powered ship would go by and he would feel like he was "choking on acid". Nobody who surfs near a port city (myself included) ever actually feels that way. He's tossed honest reporting over the side, and is instead, engaging in hyperbole to make his point.Quote:

It may still one day become profitable. But not if Germany keeps using the most expensive energy possible (which itself is heavily subsidised). for it's electrical grid.

32 mile range at 22 knots. Less if you want enough left over to motor in and out of the no wake zone and back onto the trailer. Funnn! And only a third of a million dollars to boot. Who's going to be first in line to get one?Quote:

Meh. I don’t mind. Each time someone posts something fanciful and one-sided, I’m happy to pitch in a little balance if it’s a thing I know something about.Quote:
