The power substation in our town has this big transformer out back.
It has had some issues with overheating on hot summer days. They’ve come up with a clever solution. Can you see it in that low-res cell phone picture above? Here’s a closeup.
That’s a hose, a splitter, and two bar sprinklers ziptied to the side of the transformer. They just turn the hose on when it gets hot. Problem solved.
Something bothers me about this solution though. I’m not sure what it is…
