@Semiapies:

>It is admittedly using stored energy - the propellers are spun by the wheels, which are spinning due to the vehicle's forward motion.

I'm sorry, but by that logic your car is also "admittedly using stored energy" to accelerate (as the wheels and other parts are turning due to the vehicles forward motion) and we know this isn't the case. Just because there exists stored energy in a system, doesn't mean that this stored energy is being used and in fact, as the vehicle accelerates, more energy is stored rather than energy being used.

In the case of this vehicle, it can't be using the stored energy in the propeller without it turning progressively slower and the videos show the propeller simply continuing to spin faster as the vehicle accelerates.

The gearing between the prop and the wheels is fixed ... there's no way to slow the prop down and speed the wheels up -- that would require a variable ratio between the two.

Semiapies: <<Trying to put skeptics on the defensive and trying to force them to disprove the remarkable claim put forth is a classic shtick.

I don't recall attempting to force you to disprove anything. I simply asked period of time would convince you. You can call it "shtick" if you like -- I call it attempting to learn your position.
