Oh ok thanks Surely this concept could be used elsewhere? I just realized it is:
The hover-craft: Barely any friction = Less power needed.

Its cool

You just didn’t like being proved wrong. Stop being ignorant, and take it in stride.

With the exception of the minimal amount of friction increase from bearings heating up, the friction is constant. That treadmill could have been running 100 miles an hour in reverse, and he still wouldn’t have needed to move the stick more than he did.

I have to be honest, I had a hard time wrapping my mind around the concept until this video. I see now that the only way that a conveyor would keep it stationary is if the pilot forced it to. The only way it wouldn’t fly is if the max force the propeller produced was only enough to overcome the friction. And if that was the case, then the plane wouldn’t fly even without a conveyor!

Now do a helicopter on a turntable.

I think you explained this better than mythbuster did.

So basically when you overcome friction the plane enters some kind of physical homeostasis (yeah I know its not the right use of the word) where the wheels match the speed of the treadmill no matter haw much you accelerate the treadmill. If you suddenly decrease the speed of the treadmill to 0 will the plane continue at the speed it was going? and if so could we use this to make the worlds smallest runway?
