Abstract

The accelerating build-out of solar farms on Earth is already hitting speed bumps, including public pushback against the large tracts of land required and a ballooning backlog of requests for new transmission lines and grid connections. Energy experts have been warning that electricity is likely to get more expensive and less reliable unless renewable power that waxes and wanes under inconstant sunlight and wind is backed up by generators that can run whenever needed. To space enthusiasts, that raises an obvious question: Why not stick solar power plants where the sun always shines?

空中城堡？一个怀疑论者对从太空向地球传输电力的看法

地球上太阳能发电场的加速建设已经遇到了一些障碍，包括公众对所需大片土地的反对，以及新输电线路和电网连接申请的不断积压。能源专家一直警告说，除非在不稳定的阳光和风力作用下时好时坏的可再生能源能够得到随时运行的发电机的支持，否则电费可能会越来越贵，可靠性也会越来越低。对于太空爱好者来说，这提出了一个显而易见的问题：为什么不把太阳能发电站建在阳光普照的地方呢？
