Windmills are more efficient when they are high up. A line of pylons could take a small windmill on the top with little modification There is usually an earth wire running between the pylons. We would need a second line for carrying the output of the windmills. At intervals, we might have voltage and
current converters to convert the windmill power so it can be fed into the grid on the other wires.
These won't be huge windmills unless they are very tall, which might need a new sort of pylon to hold it up. The windmill has to rotate to track the wind without hitting the other wires.
You can hang solar panels from the pylon too.

I'm going to speculate that the pylons were engineered to withstand a specific amount of wind shear. Adding a turbine at the top might change those calculations. |

Apart from that, I like it. [+] |

There are 22,000 transmission line towers in England and Wales, and perhaps another 10-15,000 in Scotland. If you could fit each one with a 1KW generator that's 32 MW capacity. If the extra wind loading doesn't fold the towers in a high wind, overstress the foundations, cause serious resonant oscillations, or risk arcing to the conductor wires, you get a conditional bun from me [+] |

Just eyeballing pylons in the UK, I reckon they could take it. The first pylons went up in the 1920's and the design has not visibly changed much. I expect the pylon design has to be strong enough to stand the unbalanced forces while stringing the lines up. I have seen one or type pylons next to substations with wires on one side, so I guess pylons are probably stiffer than they need be when loaded evenly. |

Yes, and some pylons have the conductors coming off the transmission tower at an angle other than 'straight on', so tugging it to the side, although the foundations are no doubt asymmetric. But the wind can blow from the left, or from the right can't it? |

P.s. I know it's sad, but does anyone else have a favourite curve? Mine is the catenary, even better then the tautochrone, though that comes close. |
|

@bhumphreys The catenary is good. The cycloid is a brachistochrone and a tautochrone, and the secret of the Huygens isochronous pendulum. However, I am boring: my favourite element is Carbon and my favourite curve is the circle. |
