NASA, Joby Complete eVTOL Flight Tests - AVweb

Electric cars are able to function adequately in certain scenarios, but they can hide their immense weight as they don’t need to levitate.

As useful load is a primary design consideration it is impossible for electric aircraft, especially a VTOL to be practical.

The day may come when we have Star Trek technology batteries, but lithium laptop batteries won’t fly. Literally and figuratively.

(Yes I know there are examples of tiny Li battery aircraft that can break the surly bonds of Earth, but I am speaking practical transport class aircraft and VTOLs in this context)
