Another big question is going to be its tendency to injure people whose extremities get caught in it or are scraped by it. Bicycle wheels are relatively benign

Another big question is going to be its tendency to injure people whose extremities get caught in it or are scraped by it. Bicycle wheels are relatively benign compared to this design which looks like a grater or cookie cutter. Sure, you could round things, choose less nasty materials, etc., but the price is going to go way up.

I don't quite see the difference between metal spokes rotating at moderate RPMs and metal loops rotating at moderate RPMs.

  Spokes must have a much bigger cross-section than those loops, making them less likely to cut you. Otherwise the loop wheels would be WAY heavier.

  Imagine a cyclist riding into someone's leg with one of these wheels vs. a spoked wheel.
