I wonder how much fuel savings can be realized with this, and where/how efficiency improves and where it gets worse. I understand a roller rocker valve system has relatively low parasitic losses, actuating the valves returns most of the energy back to the camshaft as the lob passes and the spring pushes back up. This system would use energy to actuate the valves in both directions.
