Power is not energy: why the difference matters
推荐理由
Technology Connections made a pretty good 52 minute video about it the other month
说明
这是2025年由Technology Connections发布的一部讲解,主题归在Power grid, heating & buildings。它讲的是power vs energy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:Technology Connections explains the difference between power (watts) and energy (watt-hours) and why confusing them leads to errors. It runs about 52 minutes and uses everyday examples.这些读者给出的理由,核心是:HN points to it whenever a thread mixes up power and energy, such as battery specs and solar generation.讲法不绑某一条新闻,过几年仍然可以当材料看。从2025年到2026年,有2位不同的读者在2个不同月份把它推荐出来,其中明确叫别人去看的有0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power vs energy变成能跟着复述的例子。
