It's been a while since I read the first series, so forgive me if this question appears obtuse: are Espers' powers unlimited? For example, can Mikoto continuously produce an EMF of a billion volts as long as she is in the right frame of mind (which I am aware affects an Esper's ability)? Do they get physically exhausted or run out of power? If not, does it mean anything when they say that Gunha produces a much larger AIM Dispersion Field, or is that related only to complexity and calculation ability?
