...sleep he rose at 3 a. m., started up the last 4,000 feet of sheer, snow-clad rocks to the Vallot shelter. Then rain and fog set in. Guides declared further climbing dangerous. So Minister Zay, from 3,000 feet below, dedicated a glistening hospice constructed of duraluminum* erected at 14,312 feet by the Alpine Club of France...
...Reason: all materials had to be carried up by climbers. In duraluminum they weighed seven and a half tons. In wood they would have weighed 110 tons...
...alloys were subjected to the pressure tests. They were commercial duraluminum, three aluminum alloys, a lead-calcium alloy, and an iron nitrogen alloy. Each alloy was submitted to the proper temperature, for the time necessary to insure complete solution of the precipitant. It was then quenched in water. The hardness was immediately taken. The alloy was permitted to age at room temperature, one series under high pressures, and a second series at ordinary pressures. After aging for definite time periods, hardness tests were again made...
...says his dymaxion house "is not property to be owned, but a mechanical arrangement to be used." The new model has a fixed circular core, cased in a streamlined, pearshaped shield which swings with the wind, like a feed-tray for birds.

Air will be conditioned, making bedclothes unnecessary. All machinery will fit into the central duraluminum mast. The bed pneumatic, the closets full of revolving shelves, the walls transparent but windowless, the cooking done by vacuum mazda units, dishwashing and laundry done mechanically in three minutes, all doors opening at the wave of a hand before photoelectric cells, the dymaxion house tries to do everything directly...
