- But Windstalks work on chaos and turbulence so they can be installed much closer together, said Núñez-Ameni.
This part doesn't make sense to me. A tree inside a forest is protected from the full force of the wind.
Otherwise, these seem very cool.

I guess if you have a steady, constant wind force pushing on the stalk, it won't give any change in orientation, which you need in order to generate a current. The article says current is generated when the discs in the stalk are under pressure, though:
- Each stalk will contain alternating layers of electrodes and ceramic discs made from piezoelectric material, which generates a current when put under pressure. In the case of the stalks, the discs will compress as they sway in the wind, creating a charge.
But eh, IANAMS :)
