Pancake Coil Resonance Tower

This is a personal project of ^.^ that is based on a combination of several other ideas.

The first of those ideas is the same-plane bifilar pancake coil, which was originated by Tesla (Tesla Coil Patent 512340) This type of coil, when configured in the method described in the patents (the outside of one wire connected to the inside of the other), more than doubles the coil’s self-inductance.  At the resonant frequency of the coil, the magnetic field covers the entire face of the coil and rotates, making it an excellent radiator of EMF.  There are several other ways the coils can be connected together, each have wildly different uses.  This project will use capacitive coupling of the wires, which will result in the coil acting like a capacitor.

This project also involves a Tesla switch.  The Tesla switch runs on the premise that 2 resonators that are in different points in space can not have charges that are perfectly in sync.  By connecting two resonators to a common ground with a flyback coil between them and intermittently connecting the open ends of the resonators at the right frequency, the resonators will “pour” energy back and forth between them until they are both the same value, which can never be reached.

A Stubblefield coil is also in use here.  The idea was created by Nathan Stubblefield when he noticed that using bi-metallic coils with an electrolyte between them will result in a brief magnetic field when the coils are shorted together.  The 2 metals in use at the moment are aluminum and copper.

The final ingredient to this mix is the electrolyte.  The plan is to use a Salt Cell type substrate that has piezoelectric properties and is easily “paintable” onto the coils and will glue the coil wires into place.  So far the best candidate for this mix is the zinc oxide substrate developed by Diveflyfish

The plan:

Make multiple self-resonant, bifilar, bimetallic coils which are exactly the same.  I’m opting for a coil the size of a compact disk or smaller, so that they can be stored easily.  The cells can be linked in series to produce more voltage or parallel to produce current.  When 2 series towers are made, the positive of one tower will be connected to the negative of the other tower using a linked flyback inductor.  When the other end of the towers are connected together, there should be a magnetic field produced in the core of the towers.  Storing energy as EMF is highly efficient and it can be recovered as emf between the 2 towers.

These idea is still in production as the sub-projects to it need to be completed first.  If a large interest is shown in this project I’ll release my production templates for making the bare-wire coils.

Below are some pictures of the process.  It took 600 sewing pins to hold the copper and aluminum wire in place.
