Wouldn't it be great to be picked up and whisked away to your destination without needing to be in contact with America's crumbling infrastructure of roads and bridges?
Well, Skai believes that its long-range hydrogen-powered eVTOL air taxis are the answer.

Brian Morrison, CTO of Skai and its parent company, Alaka'i Technologies:
The test vehicle is up at Minuteman Field up in Stow, and all the tests we've been conducting to date have been with it tethered to a concrete pad, which is part of the FAA requirements.,P>
"We use liquid hydrogen on board. The fuel cells actually use it in gaseous form, so it's stored in liquid but it comes out and goes through an expansion chamber which allows it to change from the liquid state into a gaseous state. Then we put it through a heat exchanger to warm it up a little bit, and that's what goes into the fuel cells."
The core philosophy is keep it simple. And by keeping it simple, we'll get certified sooner and we'll be a much lower cost vehicle than the more complex designs. You add complexity, you add weight, and you add certification risk.
In several scattered places were other roof doors like the one he had emerged from, and straight ahead stood a row of transparent objects that had to be the air-cars...
It, like the others, was small, hardly five feet high, with open sides and streamlined shells of a stuff like glass, front and back. Within was one wide seat, in front of which were three control levers which led to a boxed space below. It rested on three splayed legs.

As far as I know, the first use of the exact phrase air-taxi is found in Isaac Asimov's 1988 Prelude to Foundation.
