Give buskers the acoustic guitar with a link to the grid and every time they play they’ll generate a ton of electricity (in relative terms…)
Electro-Acoustic guitars use piezos to pick up the audio if you didn’t know

Even if we used piezo, the movement of the hanger would still have to come from some power source, which would still be the same sources like moving steam, water, or wind.

piezoelectricity is just simple electric motor

piezo crystal is electric motor. you input deformation of the crystal and get potential difference on opposite sides. other way around also works

Oh! Gotcha! Makes sense. Forgot about crystal vibrations for clockworks. Thanks!

Why not, though?
On a serious note: that’s exactly what we’re doing with lighters. At least some of them use piezo elements and not the sparkly wheel thingy to ignite the gas. And it’s real fun to zap yourself with it.

Yeah, it was a fun journey of learning to look into it. It’s quartz btw. Very piezoelectric and extremely common.

The conversion rate isn’t great.
There were talks of using them in sidewalks, but it doesn’t really make much sense really. Piezo almost always only works as energy recovery, which isn’t nothing but you will need the infrastructure which also isn’t nothing.
