Interestingly enough, my wife and I were discussing only this morning what happens to air travel when the "oil runs out"
The thugs at TSA will be out of a job with no planes in the airQuote:

Max theoretical energy capacity of lithium battery chemistry is about 3x where we are now. Max practical is much less. That's still not even close to enough for air travel.
Real Engineering did a very good analysis of the problem.

I heard a really interesting analysis of this a few years ago. Basically the TSA is an extension of welfare, by hiring what essentially amounts to unemployable people to do meaningless work as security theater. A surprising number of complete and total burnouts from highschool ended up sniffing panties at the airport, and I'm inclined to agree.Quote:

So - on the Eviation Alice all-electric aircraft web site, they claim 440 nautical mile range and 250 kph top speed, but I would have to guess that they are not at the same time...
But - the politicians will just legislate that you have to be able to do it and you stupid engineers are just in the pocket of big oil blah blah blah...
The most feared "F" word to hear during a flight is "FIRE!"
Recently, several French electric buses decided to "self-immolate" on the streets of Paris, resulting in the model being taken off the road. Imagine for a moment were such a fire to erupt on an aircraft in flight? The devastation would be immediate, making the DeHavilland Comet failures look tame in comparison. Add to that the move toward composite materials for improving strength while reducing weight, and that adds more fuel to the fire.
No way I'm flying on one of these.
The day I see a Politian be able to come up with a working design on their own and then build it as prof of concept, manage to put it through all testing, and manufacturing feasibility studies, surpass existing complete cradle to grave comparisons is the day I will hire them on staff. until then all a Politian is to me is a drain on the economyQuote:

Losing my job over Covid-19 cut my income by a bit more than half. Medical problems with my wife and myself make it seem likely that I'll not be able to work again. I've got an appointment to see a knee doc about the knees that have been troubling me since I was 19, turned 67 yesterday. Waiting for my back to get bad again after the last epidural injection to schedule another appointment for that, and when that doc can no longer help me will probably need surgery on the back. And that's just L5-S1, we've not addressed my neck problems at all yet. Wife's neck and back make mine look good. She had cataract surgery in March 2021, and is still having eye problems. Not to mention being the next best thing to blind. And I have cataract surgery scheduled June 14th, on the left eye, and if that goes well the 28th on the right eye. Next month looks like I probably have $47 that isn't already spoken for. I think I screwed up bad when I decided a decade ago that I didn't want any more government jobs. ;)Quote:
