Almost looks like a ground-effect vehicle. Doesn’t go too high; which may not really be an issue. Just high enough, so tarmac isn’t necessary.

I seem to recall a discussion on HN, where it was explained that quadcopters don’t scale up too well. I don’t remember the reasoning.

The one thing that concerns me about commodity-level flying vehicles, is the way people drive the ones that are stuck on the ground. I would want autonomous vehicles to be devloped and refined, before flying ones.

I was about to leave a snarky "glide ratio = 0" comment until I saw the note about the ballistic parachute. Wish they included the effective altitude though. I assume it would be effective from a lower altitude than the Cirrus, as this thing weighs only ~400 lbs with a human in it.

I swear I saw something like this in some kids magazine 30 years ago. It was supposedly powered by a vacuum motor. I now understand that can’t possibly work, but for many years I thought it could. I’d love it if someone else knew what I’m talking about and could send me a link to the magazine article. I assume it wasn’t trying to be a joke, this was a relatively serious kids magazine, but maybe I’ve been wrong.

That's an air bearing. Those are used in industry for moving heavy objects on flat floors.[1] Needs a very flat surface.

Because smaller prop means you need to spin faster to hit the same airflow. And efficiency usually drops by x^2 as a function of rotation velocity. Also, at high speed you have vacuum issues near the tip of the blade. Therefore, having four small rotors can easily be up to a magnitude less efficient than a helicopter.

Isn’t it crazy that Moller spent decades trying to get the basics of their flying car, only to give up inches from the finish line?

Tech has evolved so fast in the past few years that a brand new vehicle like this can go from design to production in a few years, and anyone can build a rough working prototype in their backyard.

Moller tried making an actual car-sized vehicle with 2 seats.

The Jetson One produced a minimalistic 1 seat vehicle.
