Possibility for private planes, but none for commercial planes. Just imagine a commercial passenger plane or cargo plane that needed a giant amount of electricity and like 12 hours of charging in between every flight.
Then, for safety reasons you'll need to have two batteries in case one goes bad.
You can simply do battery swaps. Plane refueling already requires heavy machinery and industrial scale. I bet battery swaps will be faster than refueling.
Haha, that's fair I didn't really vet the article as I've read about the concept and know it's true (although as you point out only on a technical level).
