If we could assume the tower needs to scale linearly in width, depth, and height, that would make a pole cost difference of 10x10x10 = 1000.
I did not make this up but 100kW/1000 is 100W so it would be on par with a 30m high pole.
The wind blows substantially stronger higher up so I’m not comparing to those on purpose, and this was easy to calculate. I also don’t know the cost or real size of this 9ft pole. If it doesn’t need blades it’ll be even lower and it might be cheaper. Perhaps it can be scaled up too.
Quick back of the napkin calculation assuming evolving tech.
9ft is about 3m.
A 100kW wind turbine needed a tower height of 30m.
That’s a factor 10 difference.
