简介:法国著名科学幻想小说家凡尔纳写过许多与海洋有关的科幻小说,其中有一本是《机器岛》。故事说的是美国资本家异想天开地用钢铁造了一座长七公里宽五公里的流动岛,作为他们的休养地。这座岛的两侧装有强大的推进机器,可以在大洋中漫游。这个写于1893年的故事,初衷是为了讽刺美国的富豪,但关于在海洋建设人工浮岛的构想却对人类是极大的启发。随着人类科技的进步,特别是近些年来的海洋技术的进步,这个构想当代人正在一步一步地实现。因为人类生存的陆地空间,已经越来越小,人们在用眼光向外星球扫描的同时,已经开始打海洋的主意。因为向海洋寻求生存空间,是比寻找新的适合生存的星球更为现实的途径。我们生存的地球,直径为12700多千米,表面积达5.1亿多平方千米。
