Hacker News 上的一个帖子讨论了一篇研究论文(arxiv.org),该论文探讨了利用地球磁场从地球自转中发电。论文初步结果显示发电量极低(30厘米的壳体仅产生0.44皮瓦)。一位评论员开玩笑说,火星殖民地的失败可能是由于尝试了这种发电系统。另一位用户则提出了一个严肃的问题,询问这种方式如果要产生大量电力,是否会随着时间的推移逐渐减缓地球的自转速度。

    Electric power generation from Earth's rotation through its own magnetic field (arxiv.org)

    My Stupid Question, please don't laugh:

    If you did this on a massive enough scale, to generate serious amounts of power, would that accidentally slow the Earth's rotation down over time?



    I'm not saying that is why we left Mars.


    Current = 25.4 ± 1.5 nA, Voltage = 17.3 ± 1.5 µV.

    Making total power for the 30cm shell = 0.44 picowatts.
