> say for a purely electric plane designed for this type of VTOL from the ground up, is it workable Sure, toys can do it. That's what all these commercial drones are doing. But there's an irritating inverse square law that says the power required to hover goes up shockingly fast when you start to increase the weight. Also, there's a reason commercial airlines don't use electric engines and batteries; the power-to-weight ratio for a gasoline engine far exceeds that of an electric+battery solution.
