How electric planes are changing flight

Love it.  I think we'll be seeing major battery changes in the next few years, there's a lot of different patents and companies bidding to bring new battery tech to the market relatively soon, and some of the new batteries are looking at a 30% improvement (potentially) in gravimetric energy density (so rather than be 34 times heavier for the equivalent power storage, they'll be more like 24 times heavier - which will potentially allow more range).
