winter has arrived early in some parts of canada, and we just had power knocked out in some communities due to ice buildup on power lines, which causes them to sag and eventually break.
remember when you were a kid and you would whip the end of a long rope back and forth to get a wave action going
along the length of said rope? why not apply the same technique to power lines to prevent ice from building up?
an oscillating machine (details t.b.d.) mounted on each tower could induce a wave action in the lines. it wouldn't have to be a huge wave, just enough of a continuous motion to prevent ice forming.
of course, the towers would probably have to be built of solid concrete to withstand the momentum of all that motion.

Interesting thought. I'm not qualified to speak authoritatively on the matter, but I'd guess that some amount of engineering has gone in to ensuring that it is quite difficult to induce oscillations of any significant amplitude in a power line. |

How about little scraper-bots that traverse the power lines continuosly knocking off the ice before it gets too heavy. For entertainment value, they could look like those bicycle-riding, balancing-on-a-tight-rope clown toys. And another stray thought: I wonder if there's enough of an EM field around a high voltage line to inductively power a robotic power line traversing gizmo? |

Surprised that resistance in the lines doesn't produce enough heat to keep them ice-free. The wonders of modern, efficient technology. |

Small semi permeable tubes attached to the top of the cable that weep a de-icing solution? |
|
| |
Or maybe just something to make the ice different pretty colors as it forms. |

Well now that's just silly. |
