I watched a video recently and you can change the direction the fan spins by applying heat to different parts too. Not sure if it was a stirling one or peltier.

Stirling engines have lots of moving parts but peltier fans just have a small white square about 4mm thick between two metal structures without why moving parts safe for the fan itself
