That's a clever idea - patent it while you can!
Come on, now, you people KNOW me! That was my "tongue-in-cheek" red-neck weather engineering coming to the forefront (hinted: Jack-O-Lantern)!

No I was serious: If the rotating cowl could effectively amplify the ambient breeze and force more air past the T/H sensor than natural ventilation provides then it could almost be a self-powered FARS. OK it wouldn't work in a literal dead calm, but if it could be engineered to be light and frictionless enough to provide useful ventilation in wind speeds as low as eg 1-2m/s then it might be an interesting invention. And if the rotational friction were minimal then even small gusts of similar wind speed might be sufficient to keep it spinning and ventilating. OK, needs some development and maybe the practicalities or cost would be too much but it's the germ of an interesting idea.

PVC is light but not that light...and...bearings are nowhere "friction-free" enough to allow it to coast long enough to useful.

Honest, it was a "lark", spur-of-the-moment, idea (ha,ha), which I was 'hinting-at/reinforcing' when I referenced the Jack-O-Lantern analogy.

Anyway, now that it's been publicly published, it is PUBLIC DOMAIN, so feel free to use / develop / exploit / market at will.


ADDENDUM - You've piqued my curiosity enough that I submitted an inquiry to an INDIA "turbine vent" manufacturing website to see what they suggest!

This is what it reminded me of:

(best watched with the sound on mute!). See one of these every day on a chimney pot, often glinting in the sun.

Yes, that's basically what I envisioned, except having external bearing supports (for open center) and being made of PVC plastic (for weight reduction) instead of metal and having a 'screened' bottom for air inlet and attachment to a central support rod upon which the T/RH sensor is attached at its top, centrally inside spinner (hence, need for external bearing supports).

Yikes! No wonder the UK wants divorce the EU! Germany wants 110 for something that costs about $50 in USA?
