You can find some amazing things at a steam pageant. For instance..... That thing in the picture is a Crosley Icy Ball refrigerator. Circa 1928 to 1938. It didn’t use any electricity. It used heat from a kerosene lamp to make the inside cold. You can learn more about the amazing Icy Ball device at this Wikipedia link: Crosley Icy Ball And if you would like to make your own Icy Ball, check out this link: Icy Ball Plans If someone actually makes one of these things, please tell me about it.
