Using Magnetic fields

I've managed to find an example of someone using the magnetic fields beneath power lines:














Richard Box planted 1301 fluorescent tubes that are not physically hooked up to anything- powered only by the EMF from the overhead lines.

Model

I managed to get the majority of my pieces cut by the laser cutter before the plug was pulled- the benefit of being prepared early I guess.
My site model is nearly complete so it's time to get my installation all figured out.
I plan to portray the forgotten aspects of of electrical infrastructure through projection.
The phases I'm going to portray (bad electrical pun- accidental I swear) are:
-Generation
-Alteration (transforming)
-Monitoring, Correcting
-Transfer

The modes of display are light, audio, and physical projection (shadows, sounds, and components breaking out of the buildings interior space)

Pieces and pieces and pieces

Scale Issues

I've been looking at breaking my model up into pieces to be cut on the laser cutter. The scale I've been looking at up until now is going to cause a lot of extra joints in assembly. In order to make this model with a reasonable amount of joints (and resultant- a reasonable amount of rigidity)- is to make it @ 1/4": 1' scale (or 1:48).
