Turbulence and race cars

So,

Looking at how a sphere behaves in relation to turbulence with a high enough Reynolds number, given it can provide lift, it could also provide downforce.

You just need to spin a big enough ball maybe through electro-magnetic forces, to create downforce.

Put this on a formula 1 or race car, and provide power through a battery, to create downforce like this?

Is there a way to speed the sphere or ball up so much that it can almost frictionless achieve a high enough Reynolds number, with its size and the flow of turbulence being such, that a car has enormous downforce?

Thank you for reading.

So that gave me the following idea for a race car:


Just electrically use power to distribute downforce like that given the size and mass of the ball.

    Note: One could use one ball in the centre of the car to give centre downforce.

    Question: Is there a point given the Reynolds point, the weight of the whole car+ball, and its lap times, that a certain mass of a ball rotating at a certain speed, would decrease the lap time? Please simulate.

Preliminary calculus note

On inverted calculus: This is just a preliminary note, without much thought put into it yet. How to state all answers? By eliminating all non-answers? Maybe. But let's start with: x != x. x = x + a x = 1 a != 0. Find a != a. This states all answers to x. Given: a != a Then a = -1, 1, 2, 3, 4, .. and a = 0  because x = x + a then a = 0 in 1 = 1 + 0 --

3-way transistor and uneven logic

Lets think about this: a 3 way transistor and uneven logic. So we have, logically speaking: a&b&c with three possible values (0,1,2): 0&0&0=0 0&0&1=0 0&0&2=0 0&1&0=0 0&1&1=1 0&1&2=0 0&2&0=0 0&2&1=0 0&2&2=2 1&0&0=0 1&0&1=1 1&0&2=0 1&1&0=1 1&1&1=1 1&1&2=1 1&2&0=0 1&2&1=1 1&2&2=2 2&0&0=0 2&0&1=0 2&0&2=2 2&1&0=0 2&1&1=1 2&1&2=2 2&2&0=2 2&2&1=2 2&2&2=2 Right? Let's update with the rest: Updating on the 4 bit propositional logic, Which should be 3 way or 2nd order uneven logic (since 1=1 is 1st order): As in: What if there were 3 true/false/X values?
