Comment: Electrically actuated valves (Score 1) 570 570

What ever happened to the development of electrically actuated valves? This was a big deal five years ago, and it was supposed to be just around the corner once they ironed out some reliability and electrical system issues... but they had vehicles on the road that worked and had over 100k miles on the clock...

The benefit here would be independently, infinitely adjustable timing for each cylinder for both intake and exhaust, and less moving mass (no camshafts). Some of this can be achieved with other technology. What happened?
