世界上有十​​亿人缺水。这个问题怎么解决？科学家正在考虑的一种可能性是将冰山从北极或南极拉到缺水的世界各地。尽管在尝试该项目之前必须回答许多问题，但是工程师，数学家和冰川学家（冰川学家）认为冰山是未来的水源。沙特阿拉伯（Saudi Arabia）对这个项目特别感兴趣，因为它严重缺水。科学家估计，将大型冰山（约1/2平方英里）运到沙特阿拉伯需要128天。然而，冰山将在第104天之前完全融化。因此，隔热是必不可少的，但是如何使冰山隔热仍然是一个尚未解决的问题。<br><br> <br><br>运输冰山的问题很多。第一个问题是选择要拉的冰山。由于其形状，在北极形成的冰山很难处理。只有一小部分在水面之上延伸（延伸），大部分冰山都在水面以下，这将使其难以拉动。另一方面，南极冰山是平坦的，像桌面一样漂浮。因此，它们将更容易移动。<br><br> <br><br>2亿吨的冰山如何移动？没有任何一艘船足以将如此巨大的重量拉入水中。也许可以使用几艘船。将绳索连接到这种大小的冰山上也是一个巨大的问题。工程师认为，大钉子或长金属杆可能会被打入冰中。如果在拉动过程中冰山破裂成几部分，会发生什么？如何将其拉过暴风雨的水域？此外，一旦冰山到达目的地，几乎没有港口可以容纳它。

One billion people in the world are short of water. How can this problem be solved? One possibility that scientists are considering is pulling icebergs from either the North Pole or the South Pole to parts of the world with a water shortage (短缺). Although many questions must be answered before such a project could be tried, engineers, mathematicians and glaciologists (冰川学家) consider the iceberg as a future source of water. Saudi Arabia (沙特阿拉伯) is particularly interested in this project because it has a great water shortage. Scientists estimate that it would take 128 days to transport a large iceberg (about 1/2 miles square) to Saudi Arabia. Yet the iceberg would be completely melted by the 104th day. Therefore, insulation would be essential, but how to insulate the iceberg remains an unsolved problem. The problems in transporting an iceberg are numerous. The first problem is choosing the iceberg to pull. The icebergs that form in the North Pole are quite difficult to handle because of their shape. Only a small portion extends (延伸) above the water – most of the iceberg is below the surface, which would make it difficult to pull. South Pole icebergs, on the other hand, are flat and float like table tops; thus, they would be much easier to move. How can a 200 million-ton iceberg be moved? No ship is strong enough to pull such enormous weight through the water. Perhaps several ships could be used. Attaching ropes to an iceberg this size is also an enormous problem. Engineers think that large nails or long metal rods (杆) could be driven into the ice. What would happen if the iceberg breaks into several pieces during the pulling? How could it be pulled through stormy waters? Furthermore, once the iceberg reached its destination (目的地), very few ports would be deep enough to store it.<br>
