I think this would also remove the problem of wind farms screwing with our air traffic control
and defence radar systems.
The surprising thing I saw in the video was the small actual amount of movement of the vibrating element. A traditional blade is doing a pretty fast degree per second clip.

The solution for the radar problem would be to stealth the turbine blades, like a rubberized RF absorbing layer, that would eliminate the blinking returns the airports are getting.
At least ones that are light, hard-wearing, and thin enough to use on an aerodynamic surface.
Might be better off just making the blades out of a radio transparent materiel that is still strong,
light, and cheep enough.
Although if this pans out, these blade-less generators look to be a better and cheaper alternative.

The phenomena they are tapping into scales no problem.
I don't see them running into an structural problems with modern lightweight composites.
The only real question is whether their generator can cope with the much greater forces of a
full scale [multi] megawatt generator reliably over the long term.
I would assume the answer to that would be yes. We routinely make devices that take those
kinds of loads, and this has very few moving parts to wear out.

The only downside thus far mentioned is individually the generators are less efficient
than current turbines.
However they are also much cheaper, and can be placed closer together.
Meaning that the cost per GWhr should be lower, and the power per unit area should
be higher for an array of these generators.
