月亮上的高塔
Tall Towers on the Moon
摘要：
月球南极可能含有大量的水在永久阴影的陨石坑那里。在月球基地提取这些水用于生命维持或制造火箭燃料将需要大量的电力，数量级为千兆瓦。获得这种力量的自然地点是“永恒之光之峰”，它位于几公里外的陨石坑边缘和永久阴影陨石坑上方的山脊上。可以捕获的太阳能的数量取决于可以建造多高的塔来支撑光伏电池板。月球的低重力、缺乏大气层和安静的地震环境表明，可以建造比地球高得多的塔。在这里，我们看看在月球上建造混凝土高塔的限制。我们之所以选择混凝土，是因为将大量铁或碳纤维运送到月球的资本成本目前非常昂贵，发电厂的盈利运营是不可能的。混凝土可以在月球表层就地制造。我们发现，最小壁厚（20厘米），塔高达几公里是稳定的。然而，所需的混凝土质量随着高度迅速增加，从1 km处的$\sim$ 760 mt到2 km处的$\sim$ 4，100 mt，再到7 km处的$\sim 10^5$ mt和17 km处的$\sim 10^6$ mt。
英文摘要：
The lunar South pole likely contains significant amounts of water in the permanently shadowed craters there. Extracting this water for life support at a lunar base or to make rocket fuel would take large amounts of power, of order Gigawatts. A natural place to obtain this power are the "Peaks of Eternal Light", that lie a few kilometers away on the crater rims and ridges above the permanently shadowed craters. The amount of solar power that could be captured depends on how tall a tower can be built to support the photovoltaic panels. The low gravity, lack of atmosphere, and quiet seismic environment of the Moon suggests that towers could be built much taller than on Earth. Here we look at the limits to building tall concrete towers on the Moon. We choose concrete as the capital cost of transporting large masses of iron or carbon fiber to the Moon is presently so expensive that profitable operation of a power plant is unlikely. Concrete instead can be manufactured in situ from the lunar regolith. We find that, with minimum wall thicknesses (20 cm), towers up to several kilometers tall are stable. The mass of concrete needed, however, grows rapidly with height, from $\sim$ 760 mt at 1 km to $\sim$ 4,100 mt at 2 km to $\sim 10^5$ mt at 7 km and $\sim 10^6$ mt at 17 km.
