Orbital Rings
推荐理由
we can build an orbital ring around Earth with today's technology, and it'd be much better than space elevators.
说明
这是2017年由Isaac Arthur发布的一部讲解,主题归在Space exploration & spaceflight。它讲的是orbital rings这一支里的具体问题,而不是把整个领域扫一遍。适合按兴趣直接看、不打算先补课的人。内容上可以概括成:Isaac Arthur explains the orbital ring, a megastructure launch-assist system that could move bulk cargo cheaply to orbit and beyond. He compares it with space elevators and discusses power transmission.这些读者给出的理由,核心是:HN commenters offer it as the likely future of cheap access to space, feasible without exotic materials.讲法不绑某一条新闻,过几年仍然可以当材料看。从2017年到2025年,有4位不同的读者在6个不同月份把它推荐出来,其中明确叫别人去看的有1次。适合用一集把一个概念补上的人。抓住它用的那个图像或类比,比背公式重要。如果已经会了基本定义,就把注意力放在它怎么把orbital rings变成能跟着复述的例子。
