Does This Motor Represent a Breakthrough in Torque Density?

Is this for real?  Possibly, but I’m always suspicious of people who claim to have “invented” some new electromechanical breakthrough, but who don’t know the units by which its supposed benefits are measured.  This guy says this motor has three time the gravimetric torque density of its predecessor as measured in Watts per kilogram, which is a unit of power density.
