Re: Batteries != energy

Use of electric aircraft is growing in the GA sector, especially in some schools. The approach taken there is hot-swappable batteries - you charge a large number of batteries (particularly overnight) then swap batteries in and out between flights rather than refueling.

I think aircraft would also have longer than 20 minutes in which to charge - the technical limit on turnaround time for most aircraft is not how long it takes to refuel (many regional flights don't refuel at every stop anyway) but how long it takes the brakes to cool down enough to allow you to take off (they have to be cool enough that they won't catch fire if you need to use heavy braking to reject a take off), which is usually between 45 and 60 minutes.
