Gen8 - Zero cogging coreless two-phase Halbach generator

I want to present you with a zero cogging coreless two-phase Halbach generator. This prototype roughly delivers 15 watts from 1500rpm with 20Ohm resistance or 12V 600mAh per a single phase. It fits in 2 square inches with half a pound worth of weight. You may utilize it in the wind and hydro energy harnessing applications for your dry camping needs or the school projects.
