tl;dr looking at historic patterns I've seen many new forms of wind energy, they all didn't make it. What stays successful is doing almost the same thing more efficient and at larger scale.
There appears to be a certain amount of scepticism as to how this design can convert the vibration into electricity.
This is the main reason: https://en.wikipedia.org/wiki/Betz%27s_law. Wind turbines are already very close to max efficiency, the only thing you can do is make them bigger and cheaper.
* Production cost $ * Production cost in terms of resources (e.g. renewable organic materials vs metal, rare earth etc.) * Maintenance $ * Complexity of maintenance * Necessary area / turbine * Necessary area / turbine * Necessary volume / turbine * Noise level * Usability in extreme environmental conditions
... and maybe other things I've missed.
