First, the fan I remember from my "youth" was "made" by my dad.
It is certainly possible the fan, motor, and housing were not
made by him, but he made/welded the legs that were attached to
it. (Well, obviously he didn't make the fan blade itself, but
the rest of it could have been, I just can't say - it just
didn't appear to be mass-manufactured at all.) Wish I had it -
just because. He painted it green and red as I remember.
Secondly, attached is a picture of a new fan I bought. I tried
to find an older one at a garage sale a month ago when the heat
started to become unbearable without A/C. So went to Target
and bought this.
It is not substantially built, hoping it is more energy
efficient, but the interesting thing is the shape and attitude
of the blades. Do you think the shape/design is done on
purpose (scientifically designed to move more air) or is it
just to appear to be different? Does seem to move a good
amount of air (actually wish it had a slower/quieter speed -
I only run it on the lowest speed of 3.) Reminds me of a
5-sided boomerang or maybe a starfish - or maybe what I think
I've seen for submarine propellers. Perhaps the wider blades
don't really move more air (cavitation????)
