So I was reading about vortex shedding, and got to know that it causes the building to resonate. Is there any way to use this resonance to generate electricity (maybe use quartz?) I am trying to make this model for a science fair. I am in grade 9 so it would help if the answers are not too complicated. Thanks.

Piezoelectricity requires a dielectric (electrically insulating body) or things internally short. High voltage but near zero current obtain. When the body relaxes, things reverse. One solution is an AC piezo-generator stack that is huge surface and minimum volume, driving a step down transformer or some such. Consider piezoelecric sneaker lights and anti-static guns for vinyl records (ask your grandparents).

Infiltrate and cover your building with taut PVDF tweeter sheet, then borrow or diddle the circuitry.
