A mystery from Mongolia
As you drive thru the vast lands of Mongolia, you are bound to be struck by an oddity – and that is how their electricity distribution poles look. Without exception, they have a concrete lower portion and then a longer wooden portion that seems to be held together by some ropes or something. For the life of me, I have not been able to understand why. Nobody seems to know why.
On the internet, there are some theories that this is driven by the fact that the frozen ground (during extreme cold weathers) can crack the wood. Which raises the question – why not make the whole thing with concrete then?
I have not been able to solve this yet…
