Musk has tendency to tout things that he and his design team have only partly thought through... the Hyperloop and the Tesla semi truck spring to mind, both of which remain basically vaporware years after they were introduced. Tesla designs tend to look a bit whiz-bang... look at the Cyber Truck. But if Tesla actually produces an *actual* design for an electric VTOL, something that has gone through a few basic engineering, manufacturing and economic passes, rest assured that those designs
won't look as godawful goofy as the kind shown in the video. You want an electric helicopter? Sure, great. Give me a good reason why it won't look like a sixty-year-old Hughes OH-6. It remains a perfectly cromulent design; good aerodynamics with minimal unnecessary nonsense. No matter what your level of technology, it is important for aircraft to be both lightweight and aerodynamic, and a lot of nonsensical bits and pieces tacked onto a fuselage of unnecessary size and angularity fights against both mass and drag.
Aircraft as designed to be as *clean* as possible. yes, there are certainly dirty birds out there; witness a fully loaded A-10 Warthog. It has a *lot* of stuff hanging off it, building up drag. But:
1) A Warthog is not designed to be economical. When it comes to blowing up enemy armor, cost is not an object.
2) All that stuff hanging off it is intended to FALL OFF.
In short: an electric aircraft will look like... a normal aircraft, with a relatively few and relatively modest changes associated with the motors and energy storage system.
