They are a good indicator that the stove is hot.

And the fans are easy to knock off the stove. Mine has fallen three times. Still works. Just bend the fan blades back into alignment.
My house felt windy just watching that video! It looks like there is still room for improvement on the science of these types of fans. (no specific models) They do offer air movement for those that need it and a neat looking device.
Those versions are good for cooling you down when its hot and you don't have electrickery. They have a kerosene or alcohol burner in the base. Not really designed for putting on top of a stove.coaledsweat wrote: ↑Tue. Mar. 02, 2021 12:29 pmhttps://www.a3bs.com/stirling-engine-fan-u49328-s ... edium=shop

I am going to pass on getting one of these Eco-fans and will be getting one of these pictured below with the money saved. These, too, will work in the event we lose power but the wife will probably grumble when her arms begin to tire...............................
