Funny story about that. Back in the early 80s when our amateur packet radio club was setting up a high speed (56kbps!) wireless network in the Atlanta area, I got the idea of using a refrigerator as an environmental chamber. We used a PC as the packet switch and it required pretty good temperature control. We'd been given a spot at the 800 ft level of Ch 11's broadcast tower. I realized that the fridge would make a fine chamber. The equipment heat would warm it in winter and the refrigeration would cool it in summer. Here are some photos of the fridge going up the tower: http://bellsouthpwp.net/j/o/johngd/files/misc/tower1.jpg http://bellsouthpwp.net/j/o/johngd/files/misc/tower2.jpg http://bellsouthpwp.net/j/o/johngd/files/misc/tower3.jpg The tower had a tiny elevator, too small to handle the 'fridge so we slung it under the cab with rope. Another guy in the group came up with another whacky idea. We painted a couple of paint cans black and glued them along with some black PVC pipe to the refrigerator. It looked like a giant handi-talkie! That thing stayed up there about a year until one day when the news chopper's live cam didn't have any blood'n'gore to broadcast. He flew around the tower zoomed in on the "handi-talkie" for a few minutes. The station manager had a cow. He vaguely knew that one of his engineers was involved with amateur radio and was using the tower. He apparently didn't realize it involved a refrigerator. He didn't give us time to get it down properly so we went up one blustery winter day, cut the fridge up with a demolition saw and pushed it over the side.
