Listen to Stephen's Radio Talk, all 6 hours, meanwhile read this patent and think about how it works, ask yourself the right questions, then play with it in the simulator to see what really does what.
This patent is Stephen's version of a WFC, he describes it in a completely different way and uses a somewhat different method. There is a lot of value in understanding this.
I am now researching into some more clues based on what I just learned, and I'll be doing more simulations. I would have to build a new cell to do any experimentation, but before I can do that I have to check out a few more details and see if it's worth it compared to my other plans.
