I like piezoelectrics and kinetic generators. The only two methods of generating electricity I know of that don’t involve steam other than solar panels.

At least, I think they’re different… Is a standard copper wire+magnet generator pizeoelectric? Or is it simply the operation is similar in that you generate electricity from moving things together? Like the difference between tiny little things in your shirt that generate electricity as you move around vs those flash lights you shake to charge.
