In my search for an effective way to protect my fruit trees from animal predators and birds, I looked at the electric fence option. But these require that the tree be insulated from the hot wires, otherwise it will be grounded and become useless. In my case, there's no way to totally insulate the tree and prevent that from happening. But I'm persisting and hoping to find a way to have a tree "defend itself" by either pulsating or steady, AC or DC current, and have it produce electrical shock at the touch - without shorting out. A twist or a trick, or through the employing of a special device or an elaborate scheme, anything that can make that possible. The challenge is to be able to electrify a mesh wire that's wrapped around the tree, and be able to keep the mesh wire "hot" despite it being touched by all the branches. We have to remember, these are small fruit trees and everything is in a very tight space and there's no room or possibility for insulation. Is that possible? This is a question for someone with deep understanding of electrical circuitry to answer and come up with a possible creative solution. I'm still hoping for one! Your comments and insight would be greatly appreciated!
