It’s a nice idea and I’m glad to see it investigated, however the efficiency of kinetic energy generation from a regular turbine is always going to be greater.
Oscillation from vortex shedding behind a cylinder depends on separation of slow moving air and the subsequent imbalance in lift on either side. You’re using some of the kinetic energy of the flow to induce the vortex shedding.
A regular turbine on the other hand uses very efficient airfoils where you can at attempt to maintain laminar flow and maximise energy extraction.
I see this technology as being great for energy harvesting on existing infrastructure. Put vibrational energy harvesters on pylons and poles in windy areas and you could power traffic lights, street lights etc.
