This is unlikely to come to pass because batteries weigh something like 80× as much as the corresponding jet fuel: https://news.ycombinator.com/threads?id=kragen

This means much less efficient flight, because lift costs energy, or much slower flight. But it's more plausible for these very short flights than for longer flights.

Solar-powered synfuel seems like a more likely mass alternative for the near future (02030-02050).
