"Again, I am not disagreeing with you, just looking at some of the logistics..."

And rightly so. I think it will initially find it's place in the more gross applications of power when it fits and where it fits and move from there. The use of it in more rural applications or simply places not in large city cores is still a mammoth market share. Think of it's application with solar, wind, grid interface, etc. The possibilities are considerable even if space considerations make it a problem for a city centre, depending on the power requirements.
