FOund that in 1960s they proposed using lasers for pruning. I guess you
could get a laser for $100 and put it on a pole, provided the cord doesn't
exacerbate things. It's time for some innovation here.

But not for $100. My husband has a degree in electro-optics, and has
been working with lasers all his career. His first jobs was with
industrial lasers. He says "Unlikely it would work, and the FAA would
have something to say about it."

Full credit for imaginative thinking, though.
