The numerical simulation of this nerdy question shows that the resistance decreases with the number of nodes along longest side, and converges to a finite value when the # of nodes approaches infinite.
Here comes my question: Can such grid or mesh design be utilized to reduce the resistance in wires/cables for long distance transport? Let's say one unit-length segment of copper wire can be treated as one unit resistor, so a copper wire mesh is basically equivalent to a grid of resistors.
Of course there exist many different ways to reduce the resistance, such as using a thicker wire (increase the cross section area), lowering the temperature, or even changing the material. But here I specifically wonder what simple circuit or topological design can do the trick, and whether it is practical or not.
