In the sci-fi comic Betelgeuse, the artist Leo presents a flying car with an unusual system for levitation and propulsion. The interesting point is that at the end of the comic, there is a page on which the "technical" behaviour of the system is described.
The principle is as follow:
- A rotating axe in the center is powered by a motor, and is the main axis on which the vehicle is built
- On this axe is linked a rope with a weight at its end, so the weight rotate around the central axe
- A mechanism (not exactly explained) tracts the rope so that when the weight is at the bottom, it is the closest to the axe, and at the top of the axe, it is the farthest
The resulting forces of this move is that the centrifugal force is more important when the weight is at the top than when it is at the bottom, thus the resulting force is upward and the axe (and so the vehicle) is tracted upward.
Here is a picture:
Question: With minor modifications/ameliorations allowed if needed, and considering that enough electrical power is available (like a "super light and powerful battery") in order to rotate, is this system a viable one? I am especially not sure if the mechanism to put the weight close or far from the rotating axe is not creating a new force that nullifies the resulting upward force?
