太阳城崛起在21世纪,人类面临着这样一项震撼宇宙的伟大任务:扩大人类活动的舞台,创造一个新世界。这个新世界的目标就是改造太阳系,建立太阳城。今天,空间科学家已为此勾划出3种独具匠心的方案。在这些方案中,未来的世界比地球大100万倍。建筑这样一个新世界,材料从何而来?科学家们想到了木星,这个罗马神话中的主神朱庇特,太阳系中最大的行星将成为新世界的矿山。让我们逐一浏览一下这些方案,或许能把我们的思路拓宽。包围太阳的中空球体这是美国普林斯顿大学物理学家迪森提出的方案。未来的人类世界是半径为1.5亿公里的中空球体,太阳被囊括在其中,地球在其边缘地带。这样一来,太阳辐射能可以说是点滴不漏了;在中空球的内球面上用绿色植物或光电池就可以把太阳能截留住。中空球的外表面积是地球的10亿倍。人类
Rising Sun City In the 21st century, mankind is faced with the great task of shaking the universe by expanding the stage of human activities and creating a new world. The goal of this new world is to transform the solar system and build Sun City. Today, space scientists have delineated three distinctive programs. In these programs, the future world is 100 million times larger than the Earth. Where do the materials come from? A scientist thinks of Jupiter, the god Jupiter in the Roman mythology, and the largest planet in the solar system to become a New World mine. Let us browse through these programs one by one, may be able to broaden our thinking. Hollow sphere that surrounds the sun This is a proposal by physicist Denton of Princeton University in the United States. The future human world is a hollow sphere with a radius of 150 million kilometers, in which the sun is embedded and the Earth at its periphery. As a result, the solar radiation can be tricky; in the hollow sphere of the inner sphere with green plants or photovoltaic cells can keep the solar energy. The outer surface of a hollow sphere is 1 billion times the size of the Earth. Humanity
