Folding balloon kite propels itself

It’s hypnotic to look at… but I’d like to know how it’s unidirectional joints work… word is it floats because it’s filled with helium – which would make it a balloon – but it is actually 6 connected prism-shaped balloons with carbon fiber rods. It has three motors and an on-board computer for control via what appears to be an iphone. Word is it’s the brainchild of mathematician Paul Schatz and it’s all together called inversion-driven propulsion: which I assume is uni-directional rotation applied to an object that folds itself perpetually. Not sure what they plan on using it for, but would probably be more useful in the ocean rather than in the air. [New Scientist]
