For what I see on the video the CycloTech comprises motors with adjustable pitch blades that are similar to vertical axis rotors placed on a horizontal axis (example Darrieus VAWT). There is no Magnus effect: lift is provided by the pitched blades, not by a whole cylinder-like shape rotating within a flow.
For Magnus effect to occur, there must be a flow (wind or sea current) on the rotating rotor. The Magnus rotor generates positive lift when the flow and the direction of rotation are well adjusted.
A Magnus rotor, like the Flettner rotor, is driven by a motor which consumes a lot of energy.
There are self-rotating rotors that generate Magnus effect like Savonius-like kites (photo below) on a horizontal axis, or Sharp rotor.
