PickVidsNebraska retiree uses earths's heat to grow oranges in snow
推荐理由
Really interesting story/concept and I'm hoping to replicate on a small scale
说明
这是2018年由Kirsten Dirksen发布的一部纪录片，主题归在Environment, agriculture & food systems。它讲的是geothermal greenhouses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：Kirsten Dirksen visits retired mailman Russ Finch in Alliance, Nebraska, who grows oranges, figs and pomegranates in a backyard greenhouse without paying for heat. The greenhouse uses the stable temperature of the earth, with underground earth tubes, to heat and cool itself.这些读者给出的理由，核心是：HN commenters bring it up in geothermal, greenhouse and vertical farming threads as a low-tech example of growing citrus in a cold climate.讲法不绑某一条新闻，过几年仍然可以当材料看。从2019年到2026年，有4位不同的读者在4个不同月份把它推荐出来，其中明确叫别人去看的有0次。适合先建立人物和来龙去脉的人。看完要能说出这件事是怎么发生的。如果已经会了基本定义，就把注意力放在它怎么把geothermal greenhouses变成能跟着复述的例子。
