The Dymaxion House was developed by inventor and architect Buckminster Fuller to address several perceived shortcomings with existing homebuilding techniques. Fuller designed several versions of the house at different times — all of them factory manufactured kits, assembled on site, intended to be suitable for any site or environment and to use resources efficiently. A key design consideration of the design was ease of shipment and assembly. As he did when naming many of his inventions, Fuller used a portmanteau of the words dynamic, maximum, and tension to arrive at the term ''Dymaxion''. 〔 〕 == History == The Dymaxion was completed in 1930 after two years of development, and redesigned in 1945. Buckminster Fuller wanted to mass-produce a bathroom and a house. His first "Dymaxion" design was based on the design of a grain bin. During World War II, the U.S. Army commissioned Fuller to send these housing units to the Persian Gulf. In 1945, science-fiction writer Robert A. Heinlein placed an order for one to be delivered to Los Angeles, but the order was never filled.〔Patterson, William H. ''Robert A. Heinlein: Learning Curve, Volume 1'', p. 371. Macmillan, 2010. ISBN 0-7653-1960-8〕 The Siberian grain-silo house was the first system in which Fuller noted the "dome effect." Many installations have reported that a dome induces a local vertical heat-driven vortex that sucks cooler air downward into a dome if the dome is vented properly (a single overhead vent, and peripheral vents). Fuller adapted the later units of the grain-silo house to use this effect. The final design of the Dymaxion house used a central vertical stainless-steel strut on a single foundation. Structures similar to the spokes of a bicycle-wheel hung down from this supporting the roof, while beams radiating out supported the floor. Wedge-shaped fans of sheet metal aluminum formed the roof, ceiling and floor. Each structure was assembled at ground level and then winched up the strut. The Dymaxion house represented the first conscious effort to build an autonomous building in the 20th century. It was a prototype proposed to use a packaging toilet, water storage and a convection-driven ventilator built into the roof. It was designed for the stormy areas of the world: temperate oceanic islands, and the Great Plains of North America, South America and Eurasia. In most modern houses, laundry, showers and commodes are the major water uses, with drinking, cooking and dish-washing consuming less than 20 liters per day. The Dymaxion house was intended to reduce water use by a greywater system, a packaging commode, and a "fogger" to replace showers. The fogger was based on efficient compressed-air and water degreasers, but with much smaller water particles to make it comfortable. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dymaxion house」の詳細全文を読む スポンサード リンク
