    Piezoelectricity is the only other I can really think of. But it’s not like we are out here smacking crystals with hammers to make power.

      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.

        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.

      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 hammer would still have to come from some power source, which would still be the same sources like moving steam, water, or wind.
