Looks very promising. What are the obstacles to get thisbattery in public use? I find debate meaningless if there are like legal constraints. In that case the legal constraingt should be addressed first otherwise a technical/scientific discussion becomes meaningless. A lot of effective physics is restricetd. Effectiveness=danger.
