Brent,

Do you have any videos or photographs of your experiments?

Interesting reading, seems to explain the HPG very well. I need to read it again and try to understand more on the concept of the spiral, and the exact effect it generates and why the author thought it was important.

This pattern of a homopolar generator according to the Tesla's principles.
The spiral configuration of the disk rotation reduces the reaction, the counterforce and eddy current.
This project, if developed properly, could lead to the creation of the first regenerative electrodynamic turbine as directed by prof. Serra-Valls.

Twin disk homopolar motor generator.
Some indications

Iron-core magnetic circuit + permanent magnet.
Spiral configuration twin disk electrically coupled via  conductive strip or belt.
This configuration allows to take power from the rotation axis greatly simplifies the electrical connection that can be achieved with brushes or mercury.

There are much better solutions than this.  Look carefully at the twin disk setup and you will see there are four sides of the magnets which aren't being utilized.  This is a waste of energy.  Learn how to use opposing fields, which allows both sides of the magnets to be utilized.  Learn how to put everything onto a single axle where the current will be extracted from the axis's of each disc, which in turns eliminates the brushes at the rim or the conductive belt which introduces additional unwanted friction into the system.  Also, the conductive belt doesn't make contact around the entire circumference of each disc.  It's making contact 180^o with the disk on one axle, and makes contact 180⁰ with the disk on the other axle.  This is equivalent to only making full contact with one disk only, and defeats the purpose of the twin discs.  You may have doubled the voltage, but you cut your amps in half, which is the same power output as a single disc.

1)  Not utilizing all sides of the magnets, which cuts your potential output power in half.
2)  Conductive belt introduces additional friction and increases input power requirements.
3)  Additional axle introduces an increase in weight and bearing losses which increases the input power requirements.
4)  Conductive belt only making contact with half of each disc at any given time, which cuts your potential output power in half.

Hi

Excellent considerations GB,

These examples in fact are only starting points, ideas that must be analyzed and improved by the contributions of all researchers ...

Post some drawing, see if you can make a brushless system.
