Peter...
I just read the whole article word for word and I agree with his description of lift. It has added a new perspective to my understanding of lift and to me it makes sense.
I'm not sure exactly what you're trying to say but I think it has to do with not seeing where/how energy is added to the system?
Think of the air standing still with reference to the ground and an airfoil comes passing through it. If you look at the air you will see that it gets accelerated from rest (zero velocity) to a positive velocity (speed and direction of movement) as the airfoil passes by. Energy has just been added to the system. So to create lift, energy has to be added to the system to get the air to flow (start moving) around the wing and for downwash to be 'created'. That downwash is then what forces the wing upwards. There are two ways to add energy into the system (ie: accelerating the air): by adding propulsive power to the airplane which gets directly transferred to the airfoil and which transfers that power (energy) to the air, or you have no engine and you use gravity as the 'engine' as gliders do. In a glider, assuming that the air is still and there are no thermals, the glider (while flying at a constant velocity) will have a constant horizontal and vertical component of velocity. That vertical component of velocity is what is adding energy to the system and the factor responsible for that vertical component is gravity.
With regard to Bernoulli: he's basically saying that there is energy added to the system and Bernoulli describes the conservation of energy for a system (where energy is neither added or subtracted from a system) so Bernoulli doesn't apply. Bernoulli is a mathematical description of an effect that happens in a closed system. Bernoulli doesn't say this:
Think of two adjacent streamlines with different speeds. Since these streamlines have different velocities forces between them trying to speed up the slower streamline and slow down the faster streamline. The speed of air at the surface of the wing is exactly zero with respect to the surface of the wing. This is an expression of viscosity. The speed of the air increases with distance from the wing. Now imagine the first non-zero velocity streamline that just grazes the highpoint of the top of the wing. If it were initially to go straight back and not follow the wing, there would be a volume of zero velocity air between it and the wing. Forces would strip this air away from the wing and without a streamline to replace it, the pressure would lower. This lowering of the pressure would bend the streamline until it followed the surface of the wing. The streamlines are bent by a lowering of the pressure. This is why the air is bent by the top of the wing and why the pressure above the wing is lowered. This lowered pressure decrease with distance above the wing but is the basis of the lift on a wing. The lowered pressure propagates out at the speed of sound, causing a great deal of air to bend around the wing.
That is essentially what is happening on a real wing. Like others have said, you need to have viscosity to produce lift. If the molecules weren't 'connected' to each other then they would have no 'communication' between streamlines and you could end up with a condition where one streamline has a velocity of 10 m/s and the two adjacent streamline velocities are 200 m/s and 3000 m/s, all while travelling in a straight line! If that were the case you would not have the air bending, and you would therefore not have any downwash.... meaning no lift.
