As a child, I always walked down to a friend's house down the dirt road to play at their hobby farm. They built a beautiful log cabin and even used a wood fire oven to heat the first and second floors. No furnace. His father was an arborist professor at the University of Minnesota.
I remember seeing something which I am not able to find online. From what I recall, it was an all steel fan blade with a 1/4" plate holding it. As soon as you placed it on the hot stove, it spun. I guess its purpose was to circulate heat off the stove and into the room. I'm sure there was more to it.
Does anyone know what I'm talking about?
I've always been interested in making wood fireplaces and stoves more efficient at spreading heat in a room through either this type of fan along with long finned heat sinks to radiate the heat.
