Was in Northern China recently,
Got to say the shiny and non-rusted transmission pylons in Hebei got me more excited than was probably warranted. I don't think I've seen a shiny pylon before, I guess we mostly just stopped building them decades ago.
On the topic of agriculture I was very impressed by all the polytunnels we spotted from the high speed rail heading north out of Beijing. Every valley, and nook and cranny was full of them.
Took a couple photos of a small town in inner Mongolia that we passed, was amazing seeing green crops in the middle of a Siberian winter.
I believe this was a farm using recycled water to grow cut flowers https://imgur.com/a/kw1IDZ3 https://imgur.com/a/kw1IDZ3
- ZeroGravitas 2y agoI think those might be a specific kind of greenhouse rather than a standard polytunnel. The back wall is essentially a solar heat store. Here's an article on them: Chinese-style Solar Greenhouses https://ag.purdue.edu/department/btny/ppdl/potw-dept-folder/2022/chinese-style-greenhouse.html https://ag.purdue.edu/department/btny/ppdl/potw-dept-folder/...
- mapt 2y agoYeah, this highly optimized passive solar design is one of those things that seems very obvious when energy is too expensive to waste on international transportation or excessive heating in a cold climate. Citrus production in 40 below zero. By pursuing artificially inexpensive energy we are doubling down on a great number of wasteful practices that are largely avoidable.
- grumpy-de-sre 2y agoThank you! That's exactly what they are. Even "higher" tech than I first anticipated.
