Interestingly, the 'challenge' with electric flight is energy density, not power. It's pretty easy and cheap to get a big, short burst of power with electricity (the Tesla acceleration trick is an example, it's just a by-product of the battery size they need for practical range. The bigger motors aren't especially expensive or heavy as a share of the whole vehicle). In this respect, the 'extra stuff" needed for an electric VTOL is less than for an IC VTOL. In either case, the 'V' portion of a trip might only account for a few percent of the flight time, and not even a large percent of the energy use.. I'm not talking about VTOL, that is a power hog. I'm again referring to a conventional STOL airplane somewhere between the size of a Caravan, a Twin Otter, or Dash 7. But using the propwash from the multiple propellers (combined with big DH double-slot flaps) to increase the lift significantly.
I suspect that we may find that there is a business case for a small number of short range, small payload E-VTOL to serve a very limited matket.. Maybe 50 miles, 4 people, backyard to rooftop/100'x100' lot. Land is expensive where there is a concentrated amount of big money, and folks with big money will spend some of it to avoid sitting in traffic. Eventually, if battery tech gets cheaper, the benefits will become more widely available.
