As you just said:

Flettner rotors are large rotating cylinders that produce aerodynamic thrust at right angles of the air passing over them. The CoFlow Jet cylinders developed by Zha don't rotate. They draw in a bit of the air from the wind blowing across and through them and then expends it at another part of the cylinder. By drawing in a small amount of air from the intake, pressurizing it using an impeller, and squirting it through the outlet, this generates a pressure imbalance and a considerable amount of thrust, which extends the full length of the cylinders.

The only difference is that Zha's rotor sucks air in and then blows out its own wind that curves around the rotor at a the precise point to get the Magnus effect to compel the ship to go forward.

More genius than the Bernoullis, Magnus and the other guys up until now.

The artificial wind is blown around the cylinder at its own quarter as needed.

“The only difference is that Zha’s rotor sucks air in and then blows out its own wind that curves around the rotor at a the precise point to get the Magnus effect to compel the ship to go forward.”

The Flettner spins to produce the pressure difference. This uses a jet of air.

You're correct the subject of the thread was about CoFlow Jet and that's a different way to a similar result, I visited their website but found no discussion of the cargo ship ideas. It's a creative engineering group with some interesting ideas.

Battery powered aircraft, innovative aerodynamics, Mars rovers, worth a quick look.
