That's very interesting! I assume that powers those "inductive current sensor thingies" in the road at the intersections too?
I have Telco in my background. The "most serious" battery setup I've ever seen has been at a main hub/CO. The battery room in Denver looked to be the size of a large house with racks and racks and racks of huge, expensive batteries.
I can only imagine what a site like 60 Hudson St, in NYC would have.
