How a wing or propeller blade actually generates lift - Delta of Energy Delta

In a past article I talked about the Quantum nature of gasses.  Also in a different article I talk about and have linked new technology on Advanced propeller or Wing Design.

This post is about conveying a simple truth about wing or propeller design.  We are told that Wings work based on lift.  But we are also told that wind generators can work based on two principles, drag or lift, as if they were different things.

What this made me realize is that people do not understand how wings or propellers actually work.  Lift and drag are not two different things, they are the same thing.  Lift is simply the ratio (or simply a difference) of two things.  How much energy is taken (or changed - delta) from the air on the underside of it, and how much energy is taken (or changed) from the air on the top of the wing.  The more energy is changed from the wind on the "underside" of the wing, and the less energy is changed from the wind on the "upperside" of the wing, the more net force will be upward.  Simple.  So you want a small delta energy of the air on the top of the wing, and a large delta energy on the bottom of the wing.

So how do you achieve this?  Simply make the "underside" of the wing have high drag, and make the "top" of the wing have low drag.  This can be done electrically, chemically, mechanically, thermally, or any other way. Electrically/materially/chemically; donate electrons to the air on the top of the wing, and steal electrons from the bottom.  Mechanically; reduce drag on the top of the wing and increase drag on the bottom (via angle of attack, texture, ridges, etc).  Thermally heat the air on the top of the wing, chill the air on the bottom.  Etcetera.

As we can see from our Tentacool design below, the underside has ridges to increase drag and the top side is swept to reduce drag.  Also making "peaks" can reduce drag as it allows air molecules to not "bunch up" while they are trying to go over a bend.

Crossection: The innovation here is the hollow blade design that allows the air to hug the top/back reducing drag on the top while progressively oscillating the air as it goes along the bottom/front face increasing drag to improve lift.

Bottom: Notice the ridges to increase drag and thus increase lift.
Top: Notice the sweeping top to reduce drag and slight ridges to help the air molecules to have more surface area to "spread out" over the surface without impeding flow.
