This element, made of thin aluminium sheets that sit atop the cathode and copper sheets that sit atop the anode, conducts electricity from the battery to the circuit.
An experiment has shown that dozens of small individually flat pieces of polished copper could be arranged into aparabolic shape and form a large, burning mirror.
In other instances, there were holes that were made and copper was, quote, pressed back until they could peer inside the caskets to see what they contained.
When an electromagnetic wave from the satellite is directed towards DISHI, the electric fields from this incoming signal will influence the electrons in the copper patch, thus generating an oscillating flow of electrons.
