They show one rolling plane video (3)and talk about it as though it is an inclined plane; the viewing angle makes it look like that but clearly it is a horizontal plane.
I agree. I think there is a mistake and that their comment is about video #2. their math assumes that the static attraction between the two spheres hold their fields and their magnetization parallel, like two parallel bar magnets in attraction.
I don't think we can criticize them with certainty on this point, everything will depend on the intensity of the attraction which in my opinion can be stronger when the axes are parallel than when they are coaxial. In the first case the field lines loop in the air over the distance of about 2 radii R + the thickness e of the tubes, above and below the poles, that is to say in all 4*(R+e). In the second case, it would be two diameters + the thickness of the tubes, so the same thing, but in the first case the whole would fit in a smaller volume, which is a priori the best arrangement for the minimal magnetic potential energy. Having said that the effects are most unusual and could be worth more investigation.
I agree, we really need to explore this avenue, there is really something new that we hadn't noticed at all. I think I will order some spherical magnets to check the facts first. Then it would be tempting to switch from the mechanical effect to an electrical effect by replacing the spherical magnets by electrons with spins all oriented in the same direction. Their forced rotation (by what means, I don't know, an induction from an alternating current?) should result in a linear displacement and therefore a continuous current, always in the same direction, something I had already tried in vain in different ways. I have collected the texts on the subject here, including the Luxembourg patent, as well as an international patent application (in fact, the same text). The patent is from Elena Vedmedenko, the only declared inventor, the applicant being the University of Berlin. So I think that Wiesendanger who co-signed the Nature paper helped her with the mathematical analysis, but that the invention is only by Elena Vedmedenko
