It is an indoor non-electric clothes dryer!
Mandi and I hang all of our laundry out on the clothes line when we can. By doing so we noticed a subsequent drop in are electric bill, almost half. But during the winter months we have been forced to revert back to using the dryer. Not now. There is enough room on the "dryer" that I built to hang two large loads of laundry. And yes the cats do think it is a jungle gym.
