Based on the ability of ice to hold a charge it might be possible to run a small pair of wires along the top of existing phone/power lines that could pop the ice off of the lines when needed. During a storm a weak positive charge would be sent down one wire in the pair making the ice negatively charged
and attracted to it. Simultaneously shutting off that charge and sending a stronger negative charge down the second wire in the pair could pop the ice off (if the ice couldn't change polarity fast enough).
The attached link has some info showing where the seed for this idea was planted.

Switch the amperage briefly. The wire heats up and dumps the ice. |

Only useful if every connected appliance is behind a power smoothing device. |

why do wires need to be ice free in the
first place? |

[+] Would this also help in the (rare) event of anyone or anything coming in contact with a live wire? |
