I just don’t see how they’re going to get the thrust they need while still keeping the plane light (batteries are heavy!) and they’ll have a terrible turn around time because of long recharging. I don’t think they’ll have an actual plane within a decade.

You’re thinking of lead-acid batteries. The various types of lithium ion batteries are considerably lighter and more compact. The Tesla automotive battery pack is very thin and serves as the floorboard of their vehicles, sort of like a skateboard and the chassis is nicknamed a skateboard in fact.

Just like my tools.
One plane, lots of batteries.

Bingo. I really don’t see this being technologically feasible. Small quadcopters and such are a very different thing from a commercial airliner.

According to their website the plan is to use swappable batteries.

Imagine what will happen if they have to get into a holding pattern.
