OK, folks, we're all talking about it but nobody's quite said it. This apparently novel motor is actually just a new manifestation of a very old concept.
The Orbo, as described, is a perpetual motion machine which uses magnetic shields. There is just one thing which is unusual about it: Instead of using physical shields, moved by solenoids, it uses an electronic shield (the toroidal coil), and it uses saturation of the core to "block" the field. The result of the use of these "active shields" is that all the while the "shield" is "in place" there is a large current draw. This large current draw, which goes to heating the coils and nothing else, throws a lot of dust in the air and makes the analysis of the motor more confusing. The thing the large current drain distracts from is that this machine, just like *all* perpetual motion machines which use magnetic shields, loses in exactly one place: The cost of moving the shields. In the case of Orbo, that's going to manifest itself in the transients as the coils are turned on and off. Once the shields are in place (or, in Orbo's case, the coils are fully energized) the behavior of a magnetic-shield perpmo is simple. It's only during the acts of putting up the shields and taking them down that it's hard to understand. Any analysis of the motor which does not pick apart the exact behavior of the transients during coil turnon/turnoff is going to leave out a key piece of the puzzle. Furthermore, any analysis which leaves out those transients is likely to arrive at the conclusion that it's OU -- just as any analysis of a classical perpetual motion machine using magnetic shields which neglects the cost of moving the shields is likely to conclude that the machine would work.
