A vertical-axis Flettner rotor is a smooth cylinder which is spun along its axis.

 As a tall vertical cylinder, the rotor has the approximate appearance of the column of a stereotypical lighthouse. If a directional light were attached at the top, it too would spin, sending out periodic flashes of light and making it even more similar to a lighthouse. Or, as it appears to be in the comic, a fully working {{w|Lighthouse#Components|lantern house}} could be fixed to the top of the non-rotating core to the rotor, making it look even more like a lighthouse (and also allowing independent control of the light's flash rate).
