You'll stumble on some fascinating things when searching for solar house material. Here's a couple of examples, about which I know little.
This spectacular space-age solar house illustration is credited to the Jo Kotula, for the Vanadium Corp. of America, and dated 1958. It was titled: "Their furnace is 93,000,000 miles away!" I don't know how or where it was used, and I've never found anything else to indicate that Vanadium was involved in making solar heating systems. But I'd sure like to know more. It's outstanding!
And this image is currently for sale on Ebay, advertised as "Solar Energy Building Press Photo." (There are several newspapers liquidating their old stock.) There is absolutely no additional information. I've asked a few knowledgeable friends, but nobody can identify this building. With its menacing appearance, it sure seems like a unique aesthetic contribution to solar architecture. I'd guess early 1980s.
Does anybody know anything more about either of these images?
