Most of us have felt the annoyance of a power outage, and almost certainly a few of them were caused by a tree or a branch falling on the power lines, and disrupting to flow of electricity at times even with spectacular fireworks effects. In order to prevent this, all trees and branches near the power lines need occasional haircuts, to prevent this from happening. But how do you trim a tall tree fast and efficient? Since it’s impossible to climb a ladder to trim each one and get any progress, the best way to do it is to use this cool tool that straps onto a helicopter and actually features a bunch of fast spinning saws and a guy in a cage. Check out the video and remember, even if they end up touching the wire up there, they are not touching the earth at the same time so they will be fine.
