This is just a cyclogyro (first patented in 1927). Works like a Voith Schneider propeller.

I’m an aerospace engineer, fun fact:

Turbines create thrust not lift. A wing’s curved shape creates lift as it moves through the air. Propeller blades have a similar shape for the same reason.
Blades in a jet turbine also have the same shape, but they don’t use this to create lift or thrust. Instead, several layers of blades suck in and compress air, which is directed to the combustion chamber and nozzle.

Those rotors are just a few years shy of their 100th birthday. This is as new and revolutionary as a vacuum train.

Jet engines dont create lift. They provide thrust so that the wings with sufficient airspeed create lift

Edit:
Ladies and Gentlemen I thought it need not be said that this was a generalized statement as in general and civil aviation the primary lift generating component at cruise the wings generate the lift.

Of course the thrust generating component has a force in the direction it is pointing, so if you direct your thrust downwards yes tour thrust will be producing more upwards force on the craft.

This generalization is very common form of abstraction to simplify the model. Of course all models are wrong but some models are useful. It is general8zed at cruise in general and civil aviation where AOA is very small the thrust component is not producing much lift so the wings are the main lift generating component, so the statement engines don't create lift, the wings do that with airspeed is not entirely correct, it is also not flat wrong. Like how staing electricity takes the path of least resistance is wrong as electricity takes everypath with current proportionate to the inverse of resistance in said path; but that makes modeling complicated so we say electricity takes the path of least resistance, it is not entirely correct it is also not wrong.

It looks like the flying car we have all been anticipating.

This is a less efficient design than regular rotors.

Wheels are just too last millenium, let’s reinvent them

glad to see the people in the comments are not taking this bullshit. Next level of not taking this bullshit is to stop consuming and interacting in these videos, don't go down your level people.

Propellers are not "too old school, " they are by far the better choice for low speed propulsion, particularly when takeoff distance is a concern. That is why they continue to be used in craft like the c-130.

The wheel, a cornerstone of modern life, is millenia old.

My dad manufactures cf and in the 80s made a device that looked in all honesty like a reel to reel recorder. It had no regular fins just two pitched reels on opposite sides of a central body like a drone. The reels were surrounded by a belt that used a reverse gearing to compensate the reels. So the motor operated in the opposite direction in the center of the body. It was fully working with a coandra effect if I spelled it right. His idea was not about efficiency but rather flinging air out. He had everything weighted so it would act like its own gyroscope. All it needed was a system to shift the center of gravity and he said it would have moved in any direction. It did hover though and by the time I was old enough it was not operational. After writing this it makes me wanna build an updated version with him. Using a mercury ballast that flows into channels on any side could be a way to control direction.
