When you compare the 95 percent efficiency of electric motors to the 50 percent efficiency of jet motors, they never need to.At the cost of additional power. The high energy density of jet fuel can easily give away a bit of power to compress the cabin air. With batteries, that's a significant reduction in range.
A jetliner needs to constantly bring in fresh air from outside. That air must be heated as well as compressed. We all know how much range an electric car loses when you run the cabin heater. At 0C you can dress really warmly if you must, to conserve range. At -40 (C or F) you cannot. You need to heat the air. An electric jet would lose even more range from heating the air.
Batteries are never going to rival the energy density by weight of liquid hydrocarbons. The best way to power an airplane with electricity is to use that electricity to create synthetic fuels. The energy loss from the process of making the synfuels will be nowhere near the energy cost of carrying batteries on a long-haul jetliner.

You know Pipi has all its manuals online?I’m hoping this will make it easier to get support and information on my Pipistrel Taurus Electro. The expertise on their electric system is currently just overseas. I have an A&P coming this weekend for my condition inspection. Looking forward to a fun year of soaring!
I think you underestimate future advances in battery power density and ultracapacitor technology, based on what has happened over the past few decades. Time will tell…Pure EV aircraft will not replace fuel powered for decades.
5. Company goes bankrupt.Isn't that, like, how planes work?
1. Plane concept gets announced.
2. Some big order(s) gets placed on plane concept.
3. Plane concept spends years being developed and tested.
4. Some time later, actual plane flies.
Batteries maybe but I've seen nothing on the ultracap front to suggest they are even close to today's batteries let alone have a chance at leapfrogging them.I think you underestimate future advances in battery power density and ultracapacitor technology, based on what has happened over the past few decades. Time will tell…
Bet you a MY a pure EV aircraft will not replace an equivalent Jet A medium passenger aircraft (eg 737 or A320) for at least 3 decades, likely never.I think you underestimate future advances in battery power density and ultracapacitor technology, based on what has happened over the past few decades.

I won’t be around in three decades so not taking that bet .Bet you a MY a pure EV aircraft will not replace an equivalent Jet A medium passenger aircraft (eg 737 or A320) for at least 3 decades, likely never.
Consider it estate planning?I won’t be around in three decades so not taking that bet .
Won't be a problem for Elon - Elon will jump to a blended wing supersonic design. He will probably manage to make it look SR-71 ish as well.SO, a challenge in aircraft is to store the energy AND perform inspections and maintenance.
The problem of putting batteries in wings will make it impossible to do inspection and maintenance to wing.
With fuel loaded wings "wet wings", the fuel is drained and people can actually crawl inside to do inspections and maintenance.
Then it occurred to me:
REMOVABLE AND DISPOSABLE WINGS!
Not entire wing, just the outer 2/3, just past the engines.
Yes, it is expensive, but with life limited batteries, and even typical airliner wings are life limited (fatigue, damage, etc).
Should make for an entertaining fatigue analysis.SO, a challenge in aircraft is to store the energy AND perform inspections and maintenance.

I agree that would make sense if there ever is a large surplus of solar capacity. But that is likely many decades away, unfortunately.I think Daniel above has nailed this thing perfectly. Go put some grab carbon out of the air solar powered syn fuel plants in the middle of the desert and make a carbon neutral option. Not available now and likely not cheap but most certainly doable.
