Run Less Run Faster- With PowerCranks!!!

I'm always looking for an edge when it comes to running faster- and recently stumbled onto PowerCranks. What are they? PowerCranks, which can be installed on any bicycle, allow the rider independent use of each pedal (see video)

Go here for another video PowerCranks.

Not cheap (they cost as much or more than a good spin bike), but PowerCranks look interesting. In the meantime, I guess one legged pedaling drills would be closest to the real thing.
