see this? a block wall, and a node? well yes with a tesla hairpin you may try to add the door knob caps in the correct position, at a mountain. this will give very fast charge times.. so the dimentions of the hair pin is based on the wave length of the inductor. you can attach a closed surface. or you can add batteries to be charge at each node. this is what i would do. so you have caps, at a mountain, you have your gap, and you have your nodes. each node capable of charging one battery.
