I see an error in the above equations, BxB = 0, not B^2, (the 'x' means cross product and 'B' is a vector)
Yes. I see what you are saying. B^B=0 where in this case ^ is the wedge notation of geometric algebra. In GA you can't extend a vector upon itself so ostensibly BxB=0. But note the equation. I wrote (BxB). Recall that B is the conjugate of B, i.e., B=1/B Therefore B/B=1 Therefore qv x (BxB)=qvx1=qv Now having said all this Rojas demonstrated in another You Tube video how this was most likely a fake. The perpetrator most likely drilled out one of the magnets and planted a very small battery inside. Since he was getting a voltage that matched almost exactly what one of these small batteries would put out. So the demonstration is most likely a fake. Am I bummed out? Not really. The quaternionic GFT principles are still sound. This thing should still work if calibrated and constructed properly and given a kick start
