Nikola Teslas Unipolar Motor - Part 2

I achieved high speed counter rotation of 2 copper discs. I estimate each spins at around 8000 to 10,000 rpm in this video with a combined differential of 16,000 to 20,000 rpm. The duel set of golden ratio spirals cut into the discs interacts with the spiral standing waves of the magnetic field in a frequency field effect that strengthens the magnetic field. I showed this exact same pattern in a computer animation I posted here on youtube in 2007. Here it is.
