It is a certainly an untenable problem for longhaul, though with the current pace of advances in battery tech (mainly driven by smartphone companies of all things) shorthaul electric flight could certainly find some support in the near future. Electric offers dramatic reductions in engine noise and maintenance, along with far more reliability/safety. I can see that being a selling point to some aviation execs, Norway has been trying it out, hope it works for them. > Also, a battery that weighs 100kg when full weighs pretty much 100kg when empty.
