Several small turbines per pylon would probably be best,
perhaps one of the vertical axle types.
Edit: I probably should clarify that I mean electricity pylons
supporting high-tension wires.

We initially misread the title as "Python-mounted wind turbines", and after some confusion concerning snakes settled on either a Gilliamesque animated windmill, or a crude structure surmounting a badly-made Giant Wooden Rabbit ... |

How much will it cost to reinforce every pylon to be able to stand up to the wind load? |
|
| |
It will mean completely rebuilding the pylon. They are sized to take the vertical load of the cables, wind force, and snow/ice loading. Adding rotors which need to pivot right round will add huge lateral and oscillatory loads. |
|
| |
What if they were small and carefully balanced, [ of ]? |
|
| |
If the wind is coming from all directions at once, it will be possible to balance the load on the pylon. Unfortunately, wind tends not to do this. |
|
| |
Vertical turbines, weather vanes, wheels? |
|
| |
It doen't matter if the axis of the turbine or wheel or horizontal or vertical. If the wind is coming from one direction and you're getting energy out of it, then the loading on the structure will be in one direction too, and proportional to the energy you're extracting. |
|
| |
OK then, what about getting the structure to push back slightly, using less energy than is generated from the wind? Or using gears to move the strain into the least harmful axis? |
|
| |
I have to do this [MFD] Redunant with xaviergisz's link. |
|
| |
Ah yes, it is indeed redundant. |
|
| |
I had considered wind loading, but I was thinking of
small 1-2m turbines totalling around 5-10kw, which
would, by my calculations contribute the same
amount of force as a child retrieving a kite. |
