Looking for info on old wind turbines(?) in the Mojave

I came across these along Redrock-Randsburg Road (I think) more than 20 years ago, I can’t find anything about them online. Do we have any wind turbine experts/historians in the house?

I have asked the expert/explorer/historian in the ‘You know you’re from the A.V. when…’ Facebook group if he has any insight. The page is for the Antelope Valley, but he gets around.
