I must be missing something, but to me it looks like they have everything bass ackwards.
It appears that functionally this is no different than a pedal with blocks or a thick deck, which keeps the foot higher off the spindle center.
Ask a child what it's like pedaling with blocks, or watch how their feet slip off with the pedal spinning. Of course step-in cleats make a difference but the basic issue is the same, and contrary to 100 years of trying to keep the foot closer to the spindle, or even as Shimano did sometime back below the spindle line.
Again, I might be missing something, but this just seems like another perpetual motion machine.
