No thank you. I'm not going to besmirch an 18th century house with one of these. I can't imagine anyone else looking at it and not thinking it would be an eyesore.

LOL! In the late 19th century, my forefathers in the Texas panhandle plains had what was called a "windcharger" that sounds similar in function to what you were describing (see that little two-bladed thing on top at this museum pic).
It created 12V during the dusk and early morning winds enough to avoid burning the house down with candles.
Those folks thought it was the height of beautiful 'DIY' additions to their house!!!! LOL.
Let me just add...I can assure you that, having heard both, the old stock tank windmills that made cattle ranching posible here were much creakier and more obnoxious than these new 125ft monsters going "woosh-woosh."
