Eviation's All-Electric Alice Aircraft Completes First Flight
A milestone moment: Eviation's all-electric Alice aircraft completes its first flight. (airwaysmag.com) Más...Sort type: [Top] [Newest]
OK....well done for the starship look alike! Question is, how long does it take to charge batteries after 400 nm flight and how much? Just saying!
https://www.flugzeuginfo.net/acdata_php/acdata_7773_en.php 777-300 specs.
max. Takeoff Weight 299.370 kg 660.000 lbs
max. Landing Weight 237.680 kg 524.000 lbs
So, in the real world the delta between MTOW and MLW for a 777-300 is 136,000 lbs.
Tell me how you 'dump batteries' after an engine fail on departure for a reasonable MLW that means the landing gear and associated structure don't have to weigh as much as the batteries!
A nit, I know, but there are more!

For aircraft larger than small commuter transports, the power source will likely be hydrogen fuel cells, not batteries. You can dump hydrogen.
It’s a start but with a range of 440 nm (500 miles) it’s not going to be a very practical commercial aircraft.
Harbour Air in Vancouver has been working on electric flight since 2019 which makes total sense for them where most of their flights are seaplane journeys of less than an hour (I think their longest flight is to Seattle). It will a long time before it will be practical beyond short journeys but in this niche area it should work rather well. In some remote areas it might actually be superior because you would not have to truck/ship/fly fuel in but could charge it from solar or wind power.
Electric airplanes? Yeah, that's gonna be a hard no for me. Since you can't pull over when your battery dies or suddenly catches on fire from overheating, it's only fossil fuels for me in the air.
